Osmosis

movement of water through a cell membrane (special type of diffusion) and fills the cells with water

Vacuole

storage for water, waste or food in the cell. Animal Cells have multiple small ones and Plant Cells usually have one large one

Eukaryotic Cells

a cell with a nucleus and both animal and plant cells can be this

Chloroplast

contains chlorophyll that helps plants make food; gives plants green color

Nucleus

the control center of the cell that contains chromosomes

Photosynthesis

Carbon dioxide + Water +Light energy = Sugar + Oxygen and how plants make food

Organelles in Plant Cell ONLY

Cell Wall, Chloroplast

Control Center in a cell

Nucleus

Prokaryote and Eukaryote

All cells can be classified as one of these

Diffusion

a type of passive transport that moves molecules through a cell membrane

Cell membrane

thin layer that encloses the cell and controls what enters and leaves the cell

Cell wall

surrounds the cell membrane; provides shape and support for the cell

Active transport

requires the cell to use its own energy to move substances through its cell membrane

Prokaryotic

Cells with no true nucleus

DNA

contains important information for making proteins, etc./ contains instructions

Cellular respiration

energy releasing from food

Organelles

Small structures inside cells that have special jobs
