What is a tissue membrane?
A tissue membrane is a thin layer of tissue that covers or surrounds structures in the body. These membranes serve various functions like protection, secretion, absorption, and support. Examples include the mucous membranes lining the digestive tract and the synovial membranes in the joints.
The major functions of lipids in a organism do not include?
The major functions of lipids in an organism do not include providing structural support (like proteins do) or directly aiding in enzyme catalysis (like proteins and some vitamins do). Lipids primarily act as energy storage molecules, form cell membranes, and help with insulation and protection of organs.
What are the functions that cell membranes perform?
Cell membranes perform several key functions, including acting as a barrier to regulate the passage of substances in and out of the cell, providing structural support to the cell, facilitating cell communication and signaling, and recognizing and binding to specific molecules like hormones or antigens.
Do cheetahs have cell walls or membranes?
Cheetahs do not have cell walls. However, like all living organisms, they have cell membranes that surround and protect their cells. Cell membranes regulate the passage of substances in and out of the cell.
How is the cell of a one called organism different from the cells in many celled organism?
it has more cells.
Do fungi have cell membranes?
Yes. Like plants they have both cell membranes and cell walls (but the cell walls have a different composition).
How is the cell of a one-celled organism different from the the cells of many-celled organisms?
One cell or unicellular organism cells are of simpler forms mostly prokaryotes. In one cell organisms all the vital functions which are necessary for the life is carried by the same cell. In many cell or multicellular organisms the cells are complex and are called eukaryotic cells. In multicellular organism the cells are divided and are specialized in performing different functions according to need as some cells like blood work to carry oxygen, some cell hv functions like secreating some fluids like hormones or vitamins.
What is compound lipid?
Compound lipids are a type of lipid that consist of a combination of fatty acids, alcohol, and other molecules like phosphate or sugars. They include phospholipids and glycolipids, which are essential components of cell membranes and are involved in various cellular functions.
What are the main functions of the cell membrane and what molecules is it made of?
The main functions of the cell membrane are to regulate the movement of substances in and out of the cell, provide structural support, and facilitate cell communication. The cell membrane is primarily made of phospholipids, cholesterol, and proteins.
Are cells and cell membranes the same?
no they are not, The cell is like the body and the cell membrane is like the skin of the body
What organism has diffusion?
All living organisms exhibit diffusion at some level, as it is a fundamental process for the movement of molecules such as gases, nutrients, and waste products within cells and across cell membranes. From single-celled bacteria to complex multicellular organisms like humans, diffusion plays a vital role in maintaining cellular functions.
How is a single cell like an entire organism?
Because it has a "brain" or control center.... the nucleus! It functions kinda like a human or animal, it eats and produces waste.
