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.
