How do the small molecules of oxygen and carbon dioxide move through the cell membrane?
passive transport by diffusion
What are the REACTANTS of photosynthesis?
CO2 , H2O, Sunlight
What are the REACTANTS of Cellular Respiration?
C6H12O6 and O2
What happens during the S phase of the cell cycle?
The cell's DNA is replicated.
What is the main difference between passive and active transport?
Passive: High to Low
Active: Low to High
What is osmosis? What kind of transport is it?
The movement of water. Passive.
Which organelle in the plant cell makes glucose from sunlight?
Chloroplast
In which organelle do most stages of cellular respiration take place?
Mitochondria
What is the longest phase of the cell cycle?
Interphase
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?
What types of organisms do photosynthesis?
Why is the mitochondria considered the "powerhouse" of the cell?
Because it makes energy (ATP for the cell)
two identical daughter cells
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
What are the PRODUCTS of photosynthesis?
C6H12O6 and O2
What are the PRODUCTS of photosynthesis?
CO2 , H2O, ATP
What lines up in the middle of the cell during metaphase?
sister chromatids
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.
Why are plants considered AUTOtrophs?
Because they are self-feeders. They make glucose (their own food) via photosynthesis.
What kinds of organisms can do cellular respiration?
Only Plants? Only animals? All organisms?
ALL Organisms
What is the function of the spindle fibers?
They pull sister chromatids apart to opposite sides of the cell.
What protein helps to speed up reactions, build, and break down substrates?
Enzymes
