Ch4: The Plant Cell

Plant cells are...

• Prokaryotic

• Eukaryotic

Cells that contain organelles

• Prokaryotes

• Eukaryotes

Which of the following is NOT an organelle?

• Mitochondria

• Central Vacuole

• Nucleus

• Cell Wall

T/F: All cells of a plant would contain the exact same organelles.

• True

• False

Answer explanation

Organelles will vary by function. There would be no ned for chloropasts in a root cell!

T/F: Mitochondria would be unnecessary in a cell that has chloroplasts, because the chloroplasts can photosynthesize.

• True

• False

Answer explanation

Chloroplasts manufacture sugars but those sugars still need to b converted into ATP. This happens in mitochondria, so it is much needed!

Mitochondria are considered the "powerhouse of the cell" because they produce most of the _____, a molecule necessary to power metabolism.

• Glucose

• ATP

• Starch

• Sucrose

Chloroplasts belong to a larger family of organelles known as the ...

• Ribosomes

• Plastids

• Vacuoles

• Cristae

The inner membrane of the mitochondria is highly folded to increase surface area for the reactions of respiration. This inner folded membrane is known as the...

• Lumen

• Stroma

• Cristae

• Thylakoid

T/F: Chloroplasts can change into chromoplasts. This is what happens when fruit ripens.

• True

• False

The cell membrane is semipermeable. This means...

• It is flexible

• It allows certain substances in but prevents others.

• It is mostly fluid

• It is like a truck
