Question

read each description and then identify the cell structure. write your answer on the line provided.

1. im a real \powerhouse,\ thats plain to see. i break down food to release energy. what am i?
2. im strong and stiff. cutting through me is tough. im found only in plants, but i guess thats enough. what am i?
3. my name means \colored bodies,\ and i contain dna. i pass on traits to new cells in a systematic way. what am i?
4. im the \brain\ of the cell. or so they say. i regulate activities from day to day. what am i?
5. found only in plant cells, im green as can be. i make food for the plant using the suns energy. what am i?
6. im a series of tubes. found throughout the cell. i transport proteins and other things as well. what am i?
7. im full of holes, flexible, and thin. i control what gets out. as well as what comes in. what am i?
8. proteins are made here. even though im quite small. you can find me in the cytoplasm. or attached to e.r.s wall. what am i?
9. ive been called a \storage tank\ by those with little taste. im a sac filled with water, food, enzymes, or waste. what am i?
10. since i contain many enzymes, i can digest an injured cell; and can break down a large molecule into a smaller one as well. what am i?

Explanation:

• 1: Mitochondria are known as the "powerhouse" of the cell as they break down food to release energy.
• 2: Cell wall is strong and stiff, found only in plant cells.
• 3: Chromosomes mean "colored bodies", contain DNA and pass on traits.
• 4: Nucleus is the "brain" of the cell that regulates activities.
• 5: Chloroplasts are found only in plant cells, green and make food using sunlight.
• 6: Endoplasmic reticulum is a series of tubes that transport proteins.
• 7: Cell membrane is full of holes, flexible and thin, controls what enters and exits.
• 8: Ribosomes are small, make proteins, found in cytoplasm or attached to ER.
• 9: Vacuole is like a "storage tank", a sac filled with water, food, enzymes or waste.
• 10: Lysosomes contain many enzymes, can digest injured cells and break down large molecules.
