Question

a student drew an animal cell to model the parts of the cell. the drawing shows the cell model with its internal structures. what is the name of the structure labeled x and what is its function? cell membrane: it controls what enters and leaves the cell. mitochondrion: it contains energy in the cell. chloroplast: it changes the energy of sunlight into energy the cell can use. cell wall: it provides support for the cell.

Explanation:

The structure labeled X is the cell - membrane. The cell - membrane is a selectively permeable barrier that controls the movement of substances in and out of the cell. Mitochondria are for energy - production, chloroplasts are for photosynthesis in plant cells, and cell walls provide support mainly in plant cells. In an animal cell, the outer - most structure is the cell - membrane which regulates transport.

Answer:

cell membrane; it controls what enters and leaves the cell.
