Answers & Comments
Answer:
1. A. nucleus
- In a cell their is an organelle that contains the cells DNA and controls all cellular activities. This organelle is called the nucleus.
2. C. endoplasmic reticulum
- an organelle that serves as the site of protein synthesis. One of the main functions of the smooth ER is in the synthesis of lipids.
3. C. Golgi bodies
- The Golgi apparatus is often considered the distribution and shipping department for the cell's chemical products.
4. B. mitochondrion
- The mitochondria inside a cell produces ATP, or adenosine triphosphate.
5. A. lysosome
- Lysosomes digest materials taken into the cell and recycle intracellular materials.
6. B. cell membrane
- The cell membrane controls what goes into and out of the cell
7. C. cell wall
- Pectin's aid in cell adhesion by helping the cell walls of adjacent cells to bind to one another.
8. A. vacuole
- Vacuole stores water, waste products, food, and other cellular materials.
9. B. chloroplast
- Plants use chloroplasts for the process of Photosynthesis the process used by plants to convert light energy from sunlight into starch or sugar.
10. C. cell membrane
- The cell membrane gives the cell its structure and regulates the materials that enter and leave the cell.
