Photosynthesis

Process by which most plants some protists and many types of bacteria make there own food

cell membrane

protective outer covering of all cells that regulates the interaction between the cells and the environment

cytoplasm

constantly moving gel-like mixture inside the cell membrane that contains heredity materials and is the location of most of a cells life process

cell wall

Rigid structure the encloses support and protects the cells of plant algae fungi and most bacteria

Endoplastic reticulum

What structure in the cytoplasm of a eukaryotic cells that can act Storage site process energy, materials, or manufacture, substance

nucleus

chloroplast

green, chlorophyl-containing, plant-cell organelle that uses light energy to produce sugar from carbon dioxide and water.

mitochondrion

cell organelle that breaks down food and releases energy.

ribosome

small cytoplasmic structure on which cells make their own proteins.

Mitochondria

cell organelle that breaks down food and releases energy.

Golgi body

Organelle that packages, cellular materials and transports them within the cell or out of the cell

tissue

group of similar cells that work together to do one job.

organ

structure, such as the heart, made up of different types of tissues that all work together.

cell theory

states that all organisms are made up of one or more cells, the cell is the basic unit of life, and all cells come from other cells
