grade 7 lesson 2

The cell part found only in plant cells that provides support and structure to the cell is

• Cell membrane

• Cell wall

• Nucleus

• Chloroplast

The control center of the cell. It contains the DNA

• Vacuole

• Chloroplast

• Nucleus

• Mitochondria

Organelles found in both plant cells and animal cells. It filters what goes in and out of the cell

• Cell wall

• Chloroplast

• Mitochondria

• Cell membrane

The cell membrane is selectively permeable. What does "selectively permeable" mean?

• Anything can enter.

• Nothing can enter.

• Some things can enter, while other things can't enter.

What organelle contains the DNA and is the "brain, or control center" of the cell?

• mitochondria

• nucleus

• ribosome

• cell membrane

jelly-like substance within the cell membrane that the organelles float in. 

• mitochondria
• vacuole
• chloroplasts
• cytoplasm

This organelle helps plants keep their rigid structure. 

• Cell wall
• Cell membrane
• Chloroplast
• Nucleus

If we were comparing a cell to a country, a power plant would best represent

• The nucleus

• The chloroplast

• The mitochondria

• The cell membrane

Cell parts that build proteins according to the DNA code

• Mitochondria

• Chloroplast

• Nucleus

• Ribosomes

The cell membrane is selectively permeable. What does "selectively permeable" mean?

• Anything can enter.

• Nothing can enter.

• Some things can enter, while other things can't enter.
