| A | B |
|---|
| Which structure is the location where proteins are made in the cell? | ribosome |
| Which structures do not have an external membrane component? | cytoskeleton, ribosome, nucleolus, and cell wall |
| Which structure processes and modifies proteins for excretion from cells? | Golgi body |
| Which structure regulates what enters and leaves the cell? | plasma membrane |
| What is the small membrane sac which can form from the endoplasmic reticulum or from the Golgi body? | vesicle |
| What is the large, fluid-filled, central structure found in the middle of plant cells that stores a variety of materials? | vacuole or central vacuole |
| The plastid that captures light energy and manufactures food is the __________. | chloroplast |
| The organelle associated with energy release in the cell is the __________. | mitochondrion |
| What organelle is associated with digestion of materials inside the cell? | lysosome |
| The cell part that is responsible for moving other cell parts is the _________. | cytoskeleton |
| What structure is involved in the initial routing and modification of newly formed proteins and in the formation of lipids (fats)? | endoplasmic reticulum |
| What is the structure that directs and coordinates all cellular activity? | nucleus |
| Ribosomes are assembled in which nuclear structure? | nucleolus |
| Which organelle can allow the movement of molecules because it contains protein channels? | plasma membrane |
| Ribosomes on the surface of this organelle allow newly formed proteins to enter and be initally processed. | endoplasmic reticulum or rough endoplasmic reticulum |
| This structure appears green because it contains chlorophyll, a green pigment. | chloroplast |
| A loose arrangement of cellulose fibers and other components gives this structure the ability to allow most molecules access to the rest of the cell. | cell wall |
| These structures transport molecules from the Golgi body out to the plasma membrane where the molecules can leave the cell. | vesicle |
| This special sac stores digestive enzymes and may fuse with vesicles containing food to digest the food. | lysosome |
