The Cell Cycle
Passive & Active Transport
100
The maintenance of a constant internal stat in a changing environment.
What is homeostasis
100

The process by which cells use oxygen to produce energy from food. 

cellular respiration

100

Why do cells undergo mitosis 

to replace dead or damaged cells

100

The movement of particles across the cell membrane without energy.

Passive transport 

200
In order to survive, what do your cells need to obtain?
Energy
200

Equation for photosynthesis 

carbon dioxide + water ----> sugar + oxygen 

200

All cells must do this to survive 

Obtain energy 

200

The movement of particles across the cell membrane with energy.

Active transport 

300
What can cells do when they have energy?
They make new cells, exchange materials, & eliminate waste.
300

Equation for cellular respiration

Sugar + oxygen ----> water + carbon dioxide + energy 

300

A process of cell division that forms two new nuclei that are identical to each other.

Mitosis 

300

The movement of molecules from high concentrations to low concentrations.

Diffusion

400

How does the body respond to the cold weather?

answers vary 

400

A process that plants, algae, & some bacteria use to make their own food

Photosynthesis 

400

the process by which a cell uses energy to surround a particle and enclose the particle in a vesicle to bring the particle into the cell 

Endocytosis 

400

The diffusion of water through a semi- permeable membrane.

Osmosis

500

What does a tree do to maintain homeostasis during the winter months?

loses leaves

500
Where does photosynthesis takes place?
In chloroplasts.
500

when particles are enclosed in a vesicle and released from a cell. 

Exocytosis 

500

Molecules move in and out of a cell by diffusion. You have more molecules on the outside of the cell than inside.  How will the molecules move as a result of diffusion?

into the cell
