The process by which cells use oxygen to produce energy from food.
cellular respiration
Why do cells undergo mitosis
to replace dead or damaged cells
The movement of particles across the cell membrane without energy.
Passive transport
Equation for photosynthesis
carbon dioxide + water ----> sugar + oxygen
All cells must do this to survive
Obtain energy
The movement of particles across the cell membrane with energy.
Active transport
Equation for cellular respiration
Sugar + oxygen ----> water + carbon dioxide + energy
A process of cell division that forms two new nuclei that are identical to each other.
Mitosis
The movement of molecules from high concentrations to low concentrations.
Diffusion
How does the body respond to the cold weather?
answers vary
A process that plants, algae, & some bacteria use to make their own food
Photosynthesis
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
The diffusion of water through a semi- permeable membrane.
Osmosis
What does a tree do to maintain homeostasis during the winter months?
loses leaves
when particles are enclosed in a vesicle and released from a cell.
Exocytosis
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
