Looking Inside Cells Lesson

Question 1

The is the function of a cell wall?

Answer 1

The cell wall supports and protects the cell (plant cells only).

Question 2

What is the function of ribosomes?

Answer 2

The ribosomes produce the proteins needed by the cell.

Question 3

How’s the function of mitochondria differs from the function of chloroplasts?

Answer 3

Mitochondria convert energy in food molecules to energy
the cell can use to carry out its functions, while
chloroplasts capture energy from sunlight and change it
to a form of energy cells can use in making food.

Question 4

Learn the chart from learning about cells types:

Answer 4

Organism:
1. Mixed bacteria- cell wall and cytoplasm (structures observed), unicellular, no nucleus.

2. Anabaena- cell wall and cytoplasm (structures observed), multicellular, no nucleus.
3. Onion cells- cell wall, nucleus, and cytoplasm (structures observed). Multicellular.
4. Elodea cells- cell wall, nucleus, cytoplasm, chloroplasts, vacuole (structures observed). Multicellular.
5. Human Cheek Cells- cell membrane, nucleus, cytoplasm (structures observed). Multicellular.

Question 5

What are the 3 structures all cells have?

Answer 5

The 3 structures are: cytoplasm, a cell membrane, and genetic material.

Question 6

What are the different organelles found in plant and animal cells?

Answer 6

• plant cells contain chloroplasts, a cell wall, and a very
large vacuole. Usually do not have lysosomes.
• animal cells do NOT contain chloroplasts or a cell wall.
They have lysosomes and smaller vacuoles.
