AP Biology Cells

Plant cells have ___ for cell to cell communication.

• gap junctions
• plasmodesmata
• desmosomes
• tight junctions

Which structure is common to plant and animal cells?

• central vacuole
• chloroplast
• wall made of cellulose
• mitochondrion

Which of the following is major cause of the size limits for certain types of cells?

• evolutionary progression in cell size; more primitive cells have smaller sizes.
• the need for sufficient surface area to support the cell's metabolic needs.
• limitation on the strength and integrity of the plasma membrane as cell size increases
• the difference in plasma membranes between prokaryotes and eukaryotes

A biologist ground up some plant leaf cells and then centrifuged the mixture to fractionate the organelles. Organelles in one of the heavier fractions could produce ATP in the light, whereas organelles in the lighter fraction could produce ATP in the dark. The heavier and lighter fractions are most likely to contain, respectively,

• mitochondria and chloroplasts.
• peroxisomes and chloroplasts.
• chloroplasts and peroxisomes.
• chloroplasts and mitochondria.
