Cell Structure and Function REVIEW

Which process do plant cells use to capture and store energy from sunlight?

• endocytosis
• fermentation
• glycolysis
• photosynthesis

Which transport process requires the use of cell's energy?

• diffusion
• osmosis
• active transport
• facilitated diffusion

Diffusion differs from active cell transport processes because it

• forces large molecules from a cell.
• keeps a cell's boundary intact.
• moves substances into a cell.
• needs none of a cell's energy.

What is the 'powerhouse' of the cell?

• mitochondrion
• cytoplasm
• lysosome
• ribosome

What organelle acts as a storage packet for the cell?

• mitochondrion
• cytoplasm
• vacuole
• ribosome

What feature does a typical prokaryotic cell have that is missing from some eukaryotic cells?

• mitochondrion
• cytoplasm
• vacuole
• ribosome

What explains why the ratio of cell surface area to volume affects the cell size? Cells with high surface-to-volume ratio...

• consume energy efficiently.
• produce waste products slowly.
• suffer from diseases frequently.
• transport substances effectively.

Which statement is not true of carrier proteins and channel proteins?

• Carrier proteins change shape as they function but channel proteins do not.
• Carrier proteins and channel proteins extend through the cell membrane.
• Channel proteins move items inside a cell but carrier proteins do not.
• Channel proteins and carrier proteins perform facilitated diffusion.
