What is the equation for photosynthesis?
Carbon Dioxide + Water ---> Sugar + Oxygen
100
What is diffusion?
Movement of molecules from and area of high concentration to an area of low.
100
What is the difference between a plant and an animal cell?
Plant cells have cell wall and chloroplast. Animal cells have centrioles.
100
What are the 3 parts that make up an atom?
Proton, neutron, and electron.
100
What is the charge on an ion formed when an atom has lost an electron?
Positive ion
200
What is the first step in photosyntheis?
Light absorption
200
What is the difference between osmosis and diffusion?
Osmosis is the diffusion of water.
200
What is the difference between prokaryote and eukaryote?
Prokaryote lacks a nucleus and other membrane bound organelles. Eukaryote has a nucleus and other membrane bound organelles.
200
What is a polar covalent bond?
Unequal sharing of electrons. One side is slightly positive and one side is slightly negative. Ex: Water Molecule
200
What is a concentration gradient?
Where there is a difference between two concentrations. Meaning an area of high concentration to an area of low concentration.
300
What is produced in the light dependent reaction?
Oxygen,ATP,NADPH
300
What is passive transport? What is active transport?
Passive transport does not require energy moving from an area of high to low. Active transport requires energy moving from an area of low to high.
300
What are the organelles that provide energy to the cell?
The mitochondria and chloroplast.
300
What is an enzyme?
A protein that speeds up chemical reactions.
300
What is the function of the nucleolus?
Where RNA is made.
400
What is produced during the Calvin Cycle?
High Energy Sugars
400
What is hypertonic,hypontonic,isotonic?
When the cell is in an hypertonic solution, water diffuses out of the cell, and the cell shrivels. When the cell is in an hypotonic solution, water diffuses into the cell, cell bursts. When the cell is in an isotonic solution, water diffusing out= water diffusing in normal conditions.
400
What is the site of protein synthesis?
The ribosome.
400
What is an atom that has lost or gained an electron?
An ion.
400
What is the function of the cell membrane?
Regulates what goes into and out of the cell.
500
What are 3 factors affecting the rate of photosynthesis?
Water,Temperature, and light intensity.
500
What is endocytosis and exocytosis?
Actice transport endocytosis is moving materials into the cell. Exocytosis is moving materials out of the cell.
500
What is the limiting factor in cell size?
Surface area to volume ratio.
500
What is the amount of energy that is needed to start a reaction?
Activation energy

Why do leaves appear green?
Chlorophyll does not absorb green light.
