Cell Structure: True/False
The smooth ER is studded with ribosomes
FALSE
Only plant cells contain chloroplasts
TRUE
The rough ER is studded with ribosomes
TRUE
an animal cell is smaller than a virus
FALSE: if viruses can invade animal cells, they must be smaller to fit inside.
Both plant and animal cells contain chloroplasts
FALSE: only plant cells contain chloroplasts
The plasma membrane and cell wall are the same thing
FALSE: the plasma membrane is a fluid, phospholipid bilayer, the cell wall is a rigid, outer structure layer (not found in eukaryotes).
Both prokaryotes and Eukaryotes have a plasma membrane
TRUE
Prokaryotes are generally larger than eukaryotes
FALSE: Eukaryotes are generally larger, as they are multicellular.
both prokaryotes and eukaryotes have a nucleus
FALSE: Eukaryotes have a defined, membrane-bound nucleus while prokaryotes do not.
Animal cells have a cell wall
FALSE: both plant and animal cells have a cell membrane, but animal cells do not have cell walls.
The flagella is used to keep the cell in place
FALSE: flagella are motor proteins that allow a cell to propel itself through a liquid medium (example: the "tail" of a sperm cell).
Cellular respiration takes place is the mitochondria
TRUE
photosynthesis is unique to plant cells
TRUE: Only plant cells have chloroplasts, the organelle responsible for photosynthesis.
Human beings are good examples of eukaryotic cells
TRUE: human beings are eukaryotes because they have membrane bound organelles and a nucleus where their genome is stored.
Roses are a good example of eukaryotic cells
TRUE: plants are eukaryotes because they have membrane bound organelles and a nucleus where their genome is stored.
Plant cells make their own glucose, while animal cells rely on external sources for glucose
TRUE: plants have chloroplasts, which serves as a glucose source within the plant.
an animal cell is larger than a water molecule
TRUE: water molecules constantly move in and out of animal cells via osmosis, to fit inside they must be smaller than the animal cell.
