The model illustrates a process by which a substance is taken up by a cell. which statements describe the process? a. the model shows the process of endocytosis. b. the process shown in the model requires energy from the cell. c. the cell membrane in the model remains intact throughout the process. d. the model shows the process of facilitated diffusion.

A. The model shows the process of endocytosis.

B. The process shown in the model requires energy from the cell.

Explanation:

The model shows endocytosis process. It is an active process i.e. it requires energy from the cell. In endocytosis particles like whole cells or part of cells are engulfed by another cell. Cell membrane plays an important role in this process. It invaginates to form a pocket around the incoming particle. This pocket is pinched off and the particle is contained in the newly formed vacuole from the cell membrane.

Endocytosis can be of two types, phagocytosis and pinocytosis. In phagocytosis, large particles like cells are taken in by the cell. In pinocytosis, cell takes in small solutes dissolved in extracellular fluid.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
