Multicellular multicellular organisms are organisms that consist of more than one cell.
Unicellular A single cell.
Biotic Living. Plant and animals
Abiotic Non-Living, Pysical rather than biological. Sun, rocks, air
Plasma membrane (Cell Membrane) The Gatekeeper Membrane that surrounds a cell. It controls which substances move into and out of the cell
Cell wall a rigid layer surrounding the plasma membrane of the cells of plants, fungi, and bacteria. It provides support to a plant.
Chloroplast a plastid that contains chlorophyll and in which photosynthesis takes place.
Mitochondria (Power Plant of the Cell) an organelle found in large numbers in most cells.It converts food energy to energy used by the cell.

Centrioles
Nucleoleus
Microtubules
Vesicles
Microvilli
DNA the hereditary material in a cell that carries instructions for making proteins
Central Vacuole A large sac filled with water and makes a plant more rigid. It helps stand tall!
