Cells and Cell Transport Review

If starch (solute) cannot move through a membrane, which observation would most likely be made 24 hours later?

• water will diffuse into the model cell

• the cell will change color

• the cell will shrivel

• starch will diffuse out of the cell

An organism has a cell wall, free-floating DNA, and ribosomes. What is it?

• a plant

• an animal

• a fungus

• a prokaryote

Which of these is NOT a component of the cell theory?

• all living things are made of cells

• cells form through spontaneous generation

• cells are the basic functional structure of life

• cells come from preexisting cells

"Active transport" is when a cell:

• absorbs materials from Low to High concentrations without energy

• absorbs materials from High to Low concentrations without energy

• forces materials from Low to High concentrations using energy

• does nothing

Diffusion is when the the particles move:

• From A to B

• From B to A

• from both sides equally

• not at all

Where in a cell is this structure found, and what is its purpose?

• around the nucleus; protein production

• around the cell; protection and transport

• near the nucleus; package molecules for transport

• in plant cells only; photosynthesis

What microscope should be used to observe live protozoans?

• Transmission electron microscope

• Scanning electron microscope

• Magnifying glass

• Compound light microscope

Which pair correctly matches organelles to their functions?

• mitochondria and chloroplast; control cells activities

• golgi apparatus and vessicles; make and process energy

• cell membrane and cell wall; package molecules for transport

• ribosomes, rough and smooth ER; manufacture proteins

An cell has a nucleus, a cell wall made of cellulose, and has both mitochondria and chloroplasts. What best describes this cell?

• animal

• plant

• bacteria

• fungi

When cells are placed in a hypertonic sugar solution, what will likely happen?

• water will leave the cell

• water will enter the cell

• the amount of water will stay the same

• sugar will enter the cell
