How do the small molecules of oxygen and carbon dioxide move through the cell membrane?
passive transport by diffusion
100
What are the REACTANTS of photosynthesis?
CO2 , H2O, Sunlight
100
What are the REACTANTS of Cellular Respiration?
C6H12O6 and O2
100
What happens during the S phase of the cell cycle?
The cell's DNA is replicated.
100
What is the main difference between passive and active transport?
Passive: High to Low
Active: Low to High
200
What is osmosis? What kind of transport is it?
The movement of water. Passive.
200
Which organelle in the plant cell makes glucose from sunlight?
Chloroplast
200
In which organelle do most stages of cellular respiration take place?
Mitochondria
200
What is the longest phase of the cell cycle?
Interphase
200
Homeostasis refers to the necessity of an organism to maintain constant or stable internal conditions. What structure helps cells maintain homeostasis by regulating the movement of materials into and out of a cell?
Cell Membrane

In animals, glucose is absorbed from the gut into intestinal cells against its concentration gradient. This one-way process requires energy to work. What type of transport is this?
Active transport
300
What types of organisms do photosynthesis?
Plants, Autotrophs
300
Why is the mitochondria considered the "powerhouse" of the cell?
Because it makes energy (ATP for the cell)
300
What is the end result of mitosis?
two identical daughter cells
300
The process of photosynthesis can be generally expressed by:
carbon dioxide + water 
glucose + oxygen
The process of cellular respiration can be generally expressed by:
glucose + oxygen carbon dioxide + water
What can be said about these two reactions?
The products of photosynthesis are the reactants of cellular respiration.

What is the main difference between passive transport and active transport?
Passive: High to Low
Active: Low to High
400
What are the PRODUCTS of photosynthesis?
C6H12O6 and O2
400
What are the PRODUCTS of photosynthesis?
CO2 , H2O, ATP
400
What lines up in the middle of the cell during metaphase?
sister chromatids
400
What carbohydrate is in plant cell walls to assist with structure and protection?
Cellulose

If a saltwater fish is placed into a freshwater tank, what would happen to the cells of the fish? Are the fish cells hypotonic or hypertonic?
Swell. Hypotonic.
500
Why are plants considered AUTOtrophs?
Because they are self-feeders. They make glucose (their own food) via photosynthesis.
500
What kinds of organisms can do cellular respiration?
Only Plants? Only animals? All organisms?
ALL Organisms
500
What is the function of the spindle fibers?
They pull sister chromatids apart to opposite sides of the cell.
500
What protein helps to speed up reactions, build, and break down substrates?
Enzymes
