Review!
100
The term for an organism's regulation of its internal environment to maintain stable conditions suitable for survival
Homeostasis
100
What is the concentration gradient?
The concentration of solutes inside the cell vs. outside the cell
100
The vascular tissue which transports nutrients throughout the plant
Phloem
100
What are the products of photosynthesis?
Glucose and oxygen
100
What is the main difference between viruses and living cells?
Viruses cannot reproduce on their own, they do not respond to their environment, they are much smaller...
200
What will happen to the cell in this environment?
The cell will not grow or shrink; it is an isotonic solution
200
The movement of particles from an area of higher concentration to an area of lower concentration, eventually resulting in even distribution
Diffusion
200
In which cell organelle does photosynthesis occur?
Chloroplast
200
In which cell organelle does cellular respiration occur?
Mitochondria
200
Which biomolecule makes up the cell membranes?
Lipid
300
Why does water move into a cell in a hypotonic solution?
The concentration of water is lower inside the cell
300
Endocytosis is a type of _______ transport where molecules are _____ __ the cell
active, brought/taken in
300
Growth in response to light
Phototropism
300
Glucose, C6H12O6
300
Where do substrates bind on an enzyme?
The active site
400
Name the three types of passive transport
Diffusion, facilitated diffusion, osmosis
400
A cell containing cytoplasm with 75% water is placed in a beaker with a 20% water solution. What will happen to the cell?
The cell will shrink.
(Hyper, high, the cell will dry)
400
The vascular tissue in a plant which transports water and minerals up through the plant
Xylem
400
What is the relationship between cell respiration and photosynthesis?
The products of one are the reactants of the other
400
The MAIN differences between prokaryotic and eukaryotic cells
Eukaryotic cells have a nucleus and membrane-bound organelles, prokaryotes do not
500
The feature of a cell membrane that maintains homeostasis within a cell by allowing some molecules into the cell while keeping others out.
Selective permeability
500
What type of transport would be required for the following scenario:
Cells lining the gut need to take in glucose, but at a certain time, the concentration of extracellular glucose is lower than the concentration already stored in the cells.
Active transport (the molecules need to move against the concentration gradient)
500
Plant growth in response to touch
Thigmotropism
500
What is the chemical equation for photosynthesis?
6CO2 + 6H2O --> C6H12O6 + 6O2
500
An advertisement for a health supplement for dogs claims to build lean muscle and strengthen tendons and ligaments, as well as provide energy. Which two biomolecules must the supplement contain to provide these benefits?
Proteins and carbohydrates
