What is the function of the cell membrane

A cell membrane protects a cell from it's surroundings. The cell membrane controls the movement of substances from the outside and inside of cells and organelles.

The cell membrane, also known as the plasma membrane, is the outer covering of animal cells which sits inside the cell wall of plant cells. It is semi-permeable so it allows certain materials to go in and out of the cell. Substances that can pass easily in and out of the cells include oxygen, carbon dioxide, and water. So basically, it is separates the cytoplasm from the outside environment, allowing only certain molecules to enter and exit the cell and also controls the amount of the substances that can go in and out.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
