This structure is only found in plants and prokaryotes (Gives it a rigid shape)
cell wall
cytoplasm
centriole
nucleus
Which organelle produces the energy a cell needs to carry out its function
Mitochondria
Golgi Bodies
Cytoplasm
Nucleus
Plasma membranes are selectively permeable. This means
anything can pass in and out
the membrane regulates the passage of the material in and out of the cell
glucose cannot enter the cell
cholesterol cannot enter

Hydroscopic
Hydrogenated
hydrophobic
Hydrophilic
What kinds of molecules pass through a cell membrane most easily?
ionic
small and hydrophobic
large polar
large and hydrophobic
When does diffusion stop?
After a day and a night
When the particles are evenly spread out
When there are no particles left
When all the particles leave the system
Proteins in the cell membrane allow
only water to enter the cell
the cell to interact with it's environment (surrounding cells)
the cell to attach to other cells
Endosymbiotic Theory is the idea that ______ cells could have evolved from_____cells
prokaryotic, eukaryotic
eukaryotic, animal
prokaryotic, plant
eukaryotic, prokaryotic
Which of the following observations best supports the claim that mitochondria evolved from once-free-living prokaryotic cells by the process of endocytosis?
Mitochondria produce ATP
Mitochondria contain proteins
Mitochondria exchange substances with the cytosol.
Mitochondria are surrounded by a double membrane.
Bacteria are an example of a ____ cell.
prokaryotic
eukaryotic
plant

Which of the following is a reason that cells are so small?
Cells are small because they want to maximize their surface area-to-volume ratio.
Cells are small because they want to maximize their volume-to-surface area ratio.
Cells are small because they need to produce extremely small macromolecules.
Cells are small because they prefer to work together in clusters of many thousands that wouldn't otherwise fit anywhere.
Which of the following is one way that cells increase their surface area without increasing their size?
Cells will often include perfectly spherical membranes.
Cells will often include folds in their membranes.
Cells will often include holes in their membranes.
Cells will maximize their volume.
What is the primary role of aquaporins?
To transport water across the membrane.
To change the state of water from gas to liquid.
To pump water into the mitochondria for cellular respiration.
To use water for hydrolytic purposes.
Which of the following describes the difference between passive and active transport?
passive transport involves moving solutes against the concentration gradient using ATP.
active transport involves moving solutes against the concentration gradient using ATP.
passive transport involves moving solutes with the concentration gradient using ATP.
active transport involves moving solutes with the concentration gradient using ATP.
What is the difference between the molecule transported in facilitated diffusion versus simple diffusion?
facilitated diffusion involves nonpolar solute transport through a membrane protein
simple diffusion involves nonpolar solute transport through a membrane protein
facilitated diffusion involves polar solute transport through a membrane protein
simple diffusion involved polar solute transport through a membrane protein
If ATP breakdown (hydrolysis) is inhibited, which of the following types of movement across cell membranes is also inhibited?
Movement of oxygen into a cell
Movement of water through aquaporins
Passage of a solute against its concentration gradient
Facilitated diffusion of a permeable substance
