Cell Parts

Nucleus Chromosomes are found here – the brain of the cell

Nuclear Membrane Holds nucleus together

Cell Membrane: It is fluid like and separates the cell from the outside environment. It keeps the cytoplasm inside and allows nutrients in and waste products out.

Endoplasmic Reticulum: a membrane covered cell organelle that breaks down drugs and other substances & packages proteins for delivery out of the cell.

Lysosome: Digests food articles, wastes, cell parts, and foreign invaders

Mitochondrion: This organelle is the power plant of the cell. It breaks down food particles so that energy can be produced.

Golgi Complex: organelle that modifies, packages, and transports material out of the cell.

Cytoplasm Jelly like substance within a cell

Ribosomes Where proteins are made

3 things not found in an animal cell that are found in a plant cell: Valcuole: serves as a storage container for water Cell Wall: gives a plant cell a defined shape which helps support individual part of plants. Chlorophyll: Traps light and is used to produce food for plants
