what is the advantage of having an elongated shape


What Is The Advantage Of Having An Elongated Shape?

Less drag since there is less surface area for water or air to exert resistance-creating pressure on. The result ? You can move relatively faster while still using the same energy.Nov 28, 2018

What is the advantage of a bacteria being rod shaped?

Another benefit of a rod-like shape is the inherent breaking of symmetry, allowing the cell to concentrate molecules at specific cellular locales. Despite their small size, bacteria are capable of concentrating proteins at different locations in the cell.

Why is bacterial shape important?

Simply put, bacteria with different shapes present different physical features to the outside world, and these features help cells cope with and adapt to external conditions. Even a 0.01% increase in the growth rate of E.

What is the best shape for a cell?

Therefore, if a cell is going to be spherical, it would be best to be the smallest sphere possible, because decreasing size increases the surface-to-volume ratio (i.e., the volume decreases faster than does the area that can service it with nutrients).

What is the greatest advantage of a compact state?

Advantages of a Compact State: Difficult to attack. Access to a variety of resources.

What is the advantage of a cell being shaped like a sphere?

Cell shape affects diffusion because a spherical shape would have the lowest surface-to-volume ratio compared with other non-spherical cell shapes. This is the reason why many bacteria are believed to have rod-shaped, filamentous, or curved cells [120].

What is the advantage of a cell being shaped like a cylinder?

The cylindrical rod shape, in which cell growth occurs by elongation of the wall, is advantageous as it maintains a constant surface-to-volume ratio.

What advantages do the shapes confer on bacterial types?

Bacterial morphology is extremely diverse. Specific shapes are the consequence of adaptive pressures optimizing bacterial fitness. Shape affects critical biological functions, including nutrient acquisition, motility, dispersion, stress resistance and interactions with other organisms.

What is the significance of the use of a microscope to the study of microbiology?

Light (or optical) microscopy is an important tool used by biologists. It enables them to study specimens that are too small to see with the naked eye. Light (natural or artificial) is transmitted through, or reflected from, the specimen and then passed through a system of lenses that produce a magnified image.

Why do cells of human body differ in size and shape?

Cells have different shape and size because different cell types have different functions. For example : Red blood cells are shaped like a doughnut to carry more hemoglobin, and to fit through small spaces, and neurons are long and skinny to span wide places to send signals around the body .

Why is cell size important?

The need to be able to pass nutrients and gases into and out of the cell sets a limit on how big cells can be. … The larger a cell gets, the more difficult it is for nutrients and gases to move in and out of the cell. As a cell grows, its volume increases more quickly than its surface area.

What is the significance of having different shapes and sizes of cells in the human body support your answer with three examples?

Explanation: for example:-the cells of a nerve are longest cell in our body length can be more than a metre muscle cell a cylinder or spindle shaped,but they function are different in nerve cells are used to carry a blood to the body part whereas muscular cell help to force anything.

Why is shape so important?

Learning shapes not only helps children identify and organize visual information, it helps them learn skills in other curriculum areas including reading, math, and science. … Learning shapes also helps children understand other signs and symbols. A fun way to help your child learn shapes is to make a shape hunt game.

What is an example of a elongated state?

Norway and Chile are examples of elongated states. … Archipelagos such as Philippines, Indonesia, and Fiji are examples of fragmented states. A prorupted or protruded has an extension that protrudes from the main territory. Thailand is an example of a prorupted state.

Why are compact states efficient?

Compact states have relatively equal distances from their center to any boundary much like a circle. They are often regarded as efficient states. … Prorupted states occur when a compact state has a portion of its boundary extending outward exceedingly more than the other portions of the boundary.

Which of the following is the best example of an elongated state?

Chapter 8 human geography

example of elongated state vietnam, chile, morroco, portugal, panama
perforated state whole in a state filled by another state
example of perforated state lesotho in south africa
types of physical borders water, desserts, mountains

Why was the size most effective at maximizing diffusion?

Why was that size most effective at maximizing diffusion? What are the important factors that affect how materials diffuse into cells or tissues? The most effective was the smallest cube because it had a very small amount of volume which allowed the diffusion to be easily carried out all throughout the cube itself.

Why is a large surface area to volume ratio an advantage?

Gas exchange surfaces tend to have the adaptation a large SA:volume ratio. This is advantageous as it increases the area over which gases and other materials can be transported into and out of the organism, via diffusion and active transport.

Why is it important that a cell have a large surface area relative to its volume?

Materials must be able to reach all parts of a cell quickly, and when volume is too large relative to surface area, diffusion cannot occur at sufficiently high rates to ensure this.

What advantage does a cell have by being long and thin instead of being a sphere or a cube quizlet?

What advantage does a cell have by being long and thin instead of round or square? It can increase its surface area, which can allow it to be smaller.

Why is it advantageous for the cell to be small in size?

Cells are small because they need to be able to diffuse through materials easily. Also, smaller size of the cells allows the passage of materials inside and outside of the cell easily. Cells are small in size to allow easy division and growth of the cells.

Why would a smaller cell need more mitochondria?

Why do large cells need more mitochondria? … Mitochondria is place for cellular respiration. More mitochondria = more ATP produced.

What are rods with rounded ends bacteria?

A bacillus (plural bacilli), or bacilliform bacterium, is a rod-shaped bacterium or archaeon. Bacilli are found in many different taxonomic groups of bacteria. However, the name Bacillus, capitalized and italicized, refers to a specific genus of bacteria.

What are round shaped bacteria called?

coccus, plural Cocci, in microbiology, a spherical-shaped bacterium.

What shape of bacteria is most common?

The three common shapes of bacteria are as follows:

  • Spherical shape (cocci).
  • Rod-shaped (bacilli).
  • Spirilla (spiral or twisted bacteria).

What are the advantages of microscope?

Microscopes can be used to help diagnose a number of different conditions and diseases. A typical compound microscope will include a viewing lens that magnifies an object 10 times, and four secondary lenses that magnify an object 10, 40, or 100 times.

What are the advantages and disadvantages of a microscope?

Advantage: Light microscopes have high resolution. Electron microscopes are helpful in viewing surface details of a specimen. Disadvantage: Light microscopes can be used only in the presence of light and are costly. Electron microscopes uses short wavelength of electrons and hence have lower magnification.

What is the importance of the microscope in histology?

LIGHT MICROSCOPES. Light, or optical, microscopes are essential for histological studies because they allow us to visualize cells and morphological features of tissues. Light microscope relies on glass lenses and visible light to magnify tissue samples.

How does cell shape affect function?

How might cell shape affect cell function? The shape of a cell will affect its surface area. The surface area of a cell dictates how much interaction the cell will have with its environment. Cells with high surface area are usually cells that require a lot of interaction with their environment.

Why are cells of different shapes and sizes give suitable examples?

Cells have different shapes because they do different things. … For example, neurons are very long, thin, branched cells. They also need to connect with other neurons to form communication networks, so they have many long branches, RBCs are shaped like a doughnut to carry more hemoglobin, and to fit through small spaces.

How does a cells shape relate to its function?

Cell Shape

Each cell type has evolved a shape that is best related to its function. For example, the neuron in Figure below has long, thin extensions (axons and dendrites) that reach out to other nerve cells. … The shape of the red blood cells (erythrocytes) enable these cells to easily move through capillaries.

What are the advantages of large organisms being multicellular?

Multicellular organisms thus have the competitive advantages of an increase in size without its limitations. They can have longer lifespans as they can continue living when individual cells die. Multicellularity also permits increasing complexity by allowing differentiation of cell types within one organism.

Is bigger always better for a cell?

No, bigger is not always better for the cell because it’s the same as a smaller cell it just needs requires more energy to do its functions. Describe the change in the surface area of the cube when the length of the side doubles.

Why is it important to check that the cell is big enough to continue with the cell cycle?

Why is it important to check that the cell is big enough to continue with the cell cycle? DNA in these chromosomes can be damaged by a number of agents including radiation, toxic chemicals, and free radicals. At this checkpoint, another protein known as p53 will inspect the chromosomes’ DNA for damage.
