How does the structure of a cell membrane help the cell regulate water?
by a process called osmosis. Osmosis depends on the concetration of the water inside and outside the cell.
What chemical structure makes up the cell mebrane?
The cell membrane is primarily composed of a phospholipid bilayer, which consists of two layers of phospholipid molecules. These molecules have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tail, creating a barrier that surrounds the cell and controls the movement of substances in and out of the cell. Additionally, proteins, cholesterol, and carbohydrates are also embedded within the lipid bilayer, playing important roles in cell functioning and communication.
What is a limiting factor to cell size?
the ration of volume to cell surface is the biggest factor. if it gets too big, it will take too long to transport necessary molecules form the cytoplasmic mebrane or nucleus out to the environmment or vica versa. size is usually regulated by genes encoded in the DNA.
How both passive transport and active transport are necessary for photosynthesis to occur explain?
Basic photosynthesis equation is Water + Carbon Dioxide --> Glucose + Oxygen -Water is absorbed by the roots via osmosis (passive transport), moves through the xylem and is absorbed into cells where it is needed via osmosis again -CO2 from the high concentration in the atmosphere to the low concentration in the plants cells through the stomata. It is always being used up to synthesis glucose so the lower concentration is maintained -Glucose is usually converted into sucrose (a relatively large molecule) which then requires active transport to cross the plasma mebrane, and into the phloem tubes to a storage site -I would imagine oxygen would diffuse out via the same channels that CO2 came in
5 differences between plant and animal cells?
Plant cells are a type of eukaryotic cell found in the organism within the plant kingdom. The eukaryotic cell does not contain the nucleus. The plant cell differs from other eukaryotic cells as the organelles present are different. Organelles are the major parts of the cell. Animal Cell: Animal cell is a typical eukaryotic cell with a membrane bound nucleus with the presence of DNA inside the nucleus. Unlike the eukaryotic cells of plants and, animal cells do not have a cell wall. They comprise of other organelles and cellular structures which carry out specific functions necessary for the cell to function properly.
What is the function of a cell mebrane?
what the cell membrane does is give the cell it's shape and prevents thing from come in into it and out
How does the structure of the cell membrane help the regulate water?
the cell mebrane has achannel espicially for water, in some cases according to the osmolarity around cell mebrane the water will go from high concentration to low concentration by these channels . in this way cell membrane will keep the osmotic pressure equal on both sides by movement the water
What do lipids have to do with the plasma mebrane?
The membrane is made up of a bilayer (two layers) of phospholipids.
Is the cell mebrane a cell?
No, the cell membrane is a structure that separates the interior of a cell from its external environment. It is a vital component of a cell, but the cell membrane itself is not a cell. Cells are the basic unit of life that make up all living organisms.
Explain why the term fluid mosaic model is used to describe the plasma membrane?
the arrangement of the molecules that make up a cell mebrane
What is a brain atlas?
A brain atlas shows the different types of the brain like the mebrane or the pituitary gland and what there function is.
What does zona pellucida do in an egg cell?
It is also known as vitelline mebrane. The function of the vitelline membrane is that it protects oocytes(female gametocyte), eggs, and embryos during development, and regulates interactions between ovulated eggs and free-swimming sperm during and following fertilization. : )
What model do scientist use to describe a cell mebrane why does that model help represent what a cell membrane is made out of?
A model can be used for things that are too small to see clearly.
What parts of the cell keep it intact?
i had the same question but im pretty sure its the mitochondria
What else is the eardrum called?
tympanic mebrane
Why triglycerol is not part of biological membrane?
biological membranes are composed of a phospholipid bilayer. i don't see why triglycerol would need to be a part of it. if anything a cell mebrane wouldn't work the way it should if triglycerol were a part of it.
What are the main structual components of a cell mebrane?
phospholipids and proteins
