Define the terms
100
Water enters the plant through these structures
Roots
100
What is diffusion?
The movement of particles from areas of high concentration to areas of low concentration
100
Name at least two functions of the cell membrane
Protective layer, gets rid of waste, gets nutrients, gives structure to the cell.
100
What is photosynthesis?
Chemical process where plants take CO2, sunlight and water to make glucose and O2
100
What is an autotroph?
Organisms that are able to make their own food
200
Organelle where photosynthesis takes place
Chloroplast
200
What is osmosis?
the movement of water from areas of high to low concentrations through a semipermeable membrane
200
The cell membrane is a semipermeable membrane. What does semipermeable mean?
that only certain substances can go through
200
What are the two phases in photosynthesis?
the light and the dark phase
200
What does aerobic mean?
organisms that need oxygen to survive
300
Green pigment inside the plant
Chlorophyll
300
Is energy required for diffusion to happen?
No
300
What is the cell membrane made out of? (3 main things.. what are they?)
proteins, lipids and carbohydrates
300
How is the plant able to make oxygen?
by breaking up the water molecule
300
A synonym for the word "consumer"
heterotroph
400
These pores are located in plants' leaves
Stoma
400
Give an example of diffusion
spraying perfume
400
What is the function of proteins within the cell membrane?
Allows the transport of particles in and out of the cell
400
In which phase is glucose created?
dark phase
400
When water gets out of a plant through its stomas. What is this called?
transpiration
500
Channel through which water travels inside the plant
Xylem
500
What is the difference between diffusion and osmosis?
Osmosis is the movement of water through a semipermeable membrane. Diffusion is the movement of particles from areas of high to low concentration.
500
What is the name of the lipid layer that makes up the cell membrane (it has heads and tails)
phospholipid bilayer
500
What is rubisco and what does it do?
An enzyme that attaches CO2 to a 5-carbon chain during the first step of the dark phase

hypotonic
