every living cell is surronded byu a living membrane called cell membrane which allows the passage of some molecules preventing the passage of others in this way maintains the internal composition to constant or nearly constant.

Define between plant cell and animal cell?
A plant cell has a nucleus, cytoplasm, cell wall, cell membrane and (most of the time) chloroplasts. An animal cell only has a nucleus, cytoplasm and cell membrane.
What regulates passage of materials into and out of cells?
The cell membrane controls movement of materials in and out of the cell.
Which cell structure controls what enters and leaves the cell?
The selective permeability of the cell membrane
What cell structures are made primarily from phospholipids?
cell membrane
What controls entry into and out of the cell?
Cell Membrane
Define the structure and function of the cell membrane plasma membrane?
The cell membrane consists of a lipid bilayer which is actually a phospholipid. Cell membranes are semipermiable and they regulate what enters and leaves the cell.
Define between plant cell and animal cell?
A plant cell has a nucleus, cytoplasm, cell wall, cell membrane and (most of the time) chloroplasts. An animal cell only has a nucleus, cytoplasm and cell membrane.
Define When a cell use energy to move material across cell membrane?
if it is against a concentration difference.
What is the function of the carbohydrates that stick out if the plasma membrane?
The carbohydrates help identify chemical signals and define the characteristics of the cell.
How do you define eukaryote?
A eukaryote is an organism with cells with a nucleus and other organelles enclosed within a cell membrane.
What regulates passage of materials into and out of cells?
The cell membrane controls movement of materials in and out of the cell.
Which cell structure controls what enters and leaves the cell?
The selective permeability of the cell membrane
Define a cell?
smallest unit that displays the properties of life; always contains cytoplasm surrounded by a plasma membrane.
What cell structures are made primarily from phospholipids?
cell membrane
What structure controls the passage of substances into and out of the cell?
cell membrane
What controls entry into and out of the cell?
Cell Membrane
What is the thin flexible membrane around all cells?
the cell membrane is as flexible barrier outside of the cell.
