movement of oxygen into a cell, higher to lower concentration, no energy
100
How does a plant get the food it needs to create a energy?
photosynthesis
100
What is it called when a cell divides?
Mitosis
100
What do cells make up?
Tissues
200
Name one part of a cell and tell me what it does.
Nucleus controls cell
200
What is osmosis?
Movement of water into a cell, higher to lower concentration, no energy.
200
What three things does a plant need to do photosynthesis?
water, co2, and sun
200
Why do cells need to divide?
To replace the dead cells.
200
What is a tissue?
A group of specialized cells that work together
300
What part of the cell does photosynthesis occur in?
Chlorplast
300
What is active transport?
Movement of sugars, salt, and chemicals into the cell, requires energy.
300
What two things does photosynthesis create?
Sugar and oxygen

Explain what happens during mitosis.
Chromosomes copy themselves, chromosomes fasten together, chromosomes line up in the center, chromosomes split apart, new nucleus is formed and the cell splits into two.
300
What is an organ?
A group of tissues that work together.
400
What part of the cell does cellular respiration occur in?
Mitochondria
400
How are diffusion and osmosis alike and different?
Diffusion is oxygen and osmosis is water. They both are from higher to lower concentration and do not require energy.
400
What is cellular respiration?
How a cell uses sugar and oxygen to make energy
400
What is cell differentiation?
specialization of cells
400
What is an organ system?
A group of organs that work together.
500
What is the cell theory?
All living things are made up of cells, cell are basic units of structure and function in living things, all new cells are produced from existing cells.
500
How is diffusion and active transport alike and different?
Both move stuff in. One requires energy the other does not.
500
Why would fermentation happen?
Not enough oxygen is available so the sugar is only partly broken down.
500
Why would a cell that just went through mitosis be called a daughter cell?
