Evaluate 8.13A Cell Structure and Function

Cells are the basic unit of structure and function for all living things. All cells are surrounded by a ​ (a)   that regulates what can enter or leave the cell. The chloroplasts in ​ (b)   cells allows these cells to make their own food by converting energy from the sun into sugars. Mitochondria in cells ​ (c)   energy for use in cells. Cell processes are controlled by the ​ (d)   which contains genetic material. Proteins are made by ​ (e)   using instructions in the cell's DNA.

• cell membrane
• plant
• animal
• release
• nucleus
• vacuole
• ribosomes
• cytoplasm

Answer explanation

Cell membranes regulate material entering and leavings cells. Chloroplasts in plants make food, while mitochondria in both plants and animals release energy for use in cells. A cell's nucleus controls cell processes. Ribosomes produce proteins.
