What is the most important structure of a cell?
the most important structure of a cell is the nucleus.If u dont belive it look at every cell and it always has to have a nucleus.
Are membranes the most important structures in cells?
yes but the nucleus is just as important no membrane cell dies no nucleus cell dies so they are equel
Why are cells small not big?
Probably so they are easier to repair. The problem that a cell has with growing larger is that the surface of the cell does not increase as rapidly as the volume of the cell. At the size of the largest cell, the surface area is so small relative to the volume that the cell is barely able to transpire. There are exceptions to the rule, though. The largest single cell is the slime mold plasmodium. It can be considered a single cell because their thousands of nuclei are not bounded by cell walls or membranes. Slime molds can grow to cover several square inches. They are able to transpire because of the way that their cytoplasm streams. They are the closest thing in nature to "The Blob".
What was the origianal cell theory?
The original cell theory was made hunderds of years ago, and was made of three parts. It said that all living things are made up of one or more cells, that all cells come from other cells, and that cells are the basic structure of life.
What is the definition of the organelle nucleus?
A differentiated structure within a cell, such as a mitochondrion, vacuole, or chloroplast, that performs a specific function. Well that's what I put in my test and if i remember rightly i got it right!
What steroid that makes up part of the cell membranes?
Cholesterol is a steroid that plays a key role in the structure and function of cell membranes. It helps maintain membrane fluidity and stability, and is also a precursor for the synthesis of other important molecules such as steroid hormones.
Which nutrient is a key component in cell membranes neurons and certain hormones?
Phospholipids are the key component in cell membranes, while phosphorus is essential for neurons. Cholesterol is vital for the structure and function of cell membranes and is a precursor for certain hormones, such as steroid hormones.
What steroid makes up part of the cell membranes?
Cholesterol
What steroid is found in cell membranes?
Cholesterol makes up an important part of cell membrane.
A well-known steroid that is a major component of animal cell membranes is?
Cholesterol is a well-known steroid that is a major component of animal cell membranes. It helps maintain membrane structure and fluidity, as well as serves as a precursor for the synthesis of other important molecules like hormones.
Why is the structure of a phospholipid so important to the cell?
The structure of a phospholipid, with hydrophilic heads and hydrophobic tails, allows them to form lipid bilayers that make up cell membranes. This structure provides a selective barrier that regulates the passage of substances in and out of the cell, ensuring cellular integrity and function.
Is bacterium present in a cell membrane?
Bacteria are single-celled organisms and do not have cell membranes surrounding them. They have a cell wall that provides structure and support to the cell. The cell membrane in bacteria is located beneath the cell wall.
The most important steroid molecule is?
Cholesterol is the most important steroid molecule because it serves as a precursor for the synthesis of other essential steroids in the body, including hormones like cortisol, estrogen, and testosterone. Additionally, cholesterol is a key component of cell membranes and plays a crucial role in maintaining cell structure and function.
Do protist have cell membranes?
Yes, protists have cell membranes. Cell membranes are present in all living cells, including those of protists, to regulate the passage of materials into and out of the cell and maintain cellular structure and function.
Why do animal cell membranes have different shapes then plant cell membranes?
Because the animal cells contain cholesterol as the major sterol in the plasma membrane whereas in plant cells the plasma membrane contain stigmasterol as the major sterol. How could you not know this? Are you a 1st grader?
The plasma membranes of all known cells are largely composed of what class of macromolecules?
The plasma membranes of cells are largely composed of lipids, specifically phospholipids. These phospholipids form a bilayer structure that provides a barrier for the cell, regulating the passage of molecules in and out of the cell.
Why can steroid and thyroid hormones but not amino acid-based hormones move across cell membranes?
Steroid and thyroid hormones are lipid soluble, allowing them to diffuse directly across cell membranes. Amino acid-based hormones are water soluble and require specific receptor-mediated mechanisms to enter cells.
