Streamlined body – The sperm has a streamlined body that allows it to move rapidly to reach the target egg cell. For instance the head has a tapering apex which helps reduce drag as the cell travels in the female reproductive tract.

Does shape of cell vary with function?

The shape of cell does not depend on the function they perform.

Does shape affect the rate of diffusion?

Despite the numerous factors that impacted the final results such as the difficulty to calculate and the approximation of surface area human errors through observation and lack of people controlling the results a conclusion was able to be made to answer our research question the shape of the cell does not affect …

How does cell size and shape influence the diffusion of molecules into and out of the cell quizlet?

How does cell size and shape influence diffusion into and out of the cell? As cell size increases its ability to facilitate diffusion across the cell membrane decreases. This is because its internal volume increases at a faster rate than its external surface area.

Can cell shape influence the rate of diffusion of nutrients and wastes?

Yes the shape of a cell can affect the rate of diffusion of nutrients and waste.

Does the shape of a cell affect its ability to grow?

In a new study published recently in Cell Harris and Theriot [9] developed and tested a quantitative model in which they hypothesize that the relative growth between a bacterium’s cell-wall surface and its cytoplasmic volume is the primary determinant of cell size and shape. Growth is intimately related to shape [10].

How is the shape and size of cell related to its function explain by giving examples?

Answer: the shape and size of the cells are related to the specific function they perform. some cells like amoeba have changing shapes. in some cases the cell shape could be more or less fixed and peculiar for a particular type of cell for example nerve cells have a typical shape.

How does protein structure affect function?

Protein function is directly related to the structure of that protein. A protein’s specific shape determines its function. If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids the protein becomes denatured and does not perform its function as expected.

What is structure and function of cell?

Cells provide structure and support to the body of an organism. The cell interior is organised into different individual organelles surrounded by a separate membrane. The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth.

What is the relationship between structure and function quizlet?

Structure refers to how the (body) is put together-bones muscles tendons and ligaments. Then onto the organ structure down to the cellular level. Function refers to how (the body) work.

How does the structure of cytoplasm relate to its function?

Cytoplasm provides shape to the cell. It fills up the cells thus enabling the organelles to remain in their position. The cells without cytoplasm would deflate and substances will not permeate easily from one to the other organelle. A part of the cytoplasm the cytosol has no organelles.

What happens to the shape of the hydrophobic tail in a phospholipid?

What happens to the shape of the hydrophobic tail in a phospholipid when a double bond is present in the carbon chain? … When the tail of the phospholipid is bent the molecules cannot assemble as tightly. This will increase membrane flexibility.

Why is the cell membrane structure important?

The cell membrane therefore has two functions: first to be a barrier keeping the constituents of the cell in and unwanted substances out and second to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

What are the basics of sperm structure and how does it relate to function?

The head of the sperm contains the nucleus. The nucleus holds the DNA of the cell. The head also contains enzymes that help the sperm break through the cell membrane of an egg. The midpiece of the sperm is packed with mitochondria.

What is sperm tail made of?

The tail is made of protein fibers that contract on alternative sides giving a characteristic wavelike movement that drives the sperm through the seminal fluid which also supplies additional energy. Some sperm have two heads or two tails and if the testes are too warm they may die or spermatogenesis may not occur.

How is the nucleus adapted to its function?

The cell nucleus is bound by a double membrane called the nuclear envelope. … This lipid bilayer has nuclear pores that allow substances to enter and exit the nucleus or transfer from the cytoplasm to the nucleoplasm. The nuclear envelope helps to maintain the shape of the nucleus.

How does the shape of a cell vary from each other give an example?

Explanation: 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 .

How do the shapes of nerve epithelial and muscle cells affect their functions?

Epithelial cells are smaller and flattened for gas exchange. Muscle cells are slender and rod-like. Describe how the shapes of nerve cells are well suited to their functions. Nerve cells are long with threadlike extensions that can be used to transmit motor or sensory information.

Does the diversity in cell shape reflect variation in cell function?

The variety of cell shapes seen in prokaryotes and eukaryotes reflects the functions that each cell has confirming the structure-function relationship seen throughout biology. Each cell type has evolved a shape that is best related to its function.

How does the shape of a cell affect the cell’s SA v ratio?

Consider the area and volume of a typical cell. Not all cells are spherical in shape but most tend to approximate a sphere. The formula for the surface area of a sphere is 4πr2 while the formula for its volume is 4πr3/3. … Therefore as a cell increases in size its surface area-to-volume ratio decreases.

How does size affect the movement of materials in and out of cells?
