Cell Part Review

Makes proteins RIBOSOMES

Stores food, water, minerals, and carbs. Vacuoles

Carries information that determines traits. Chromosomes

Found in plant cells only, collect sun energy to make energy. Chloroplasts

Endoplasmic reticulum This cell part make proteins and lipids, and moves materials within the cell. Endoplasmic reticulum

Generates energy for the cell by breaking down food. Mitochondria

Control center of the cell. Nucleus

Provides internal support and structure and moves materials within the cell. Cytoskeleton

Jelly-like material that contains the cell parts. Cytoplasm

Controls what goes into and out of the nucleus. Nuclear envelope

Makes ribosomes and located in the nucleus. Nucleolus

Found in animal cells only, helps with cell division. Centrioles

Found in plants cells, and is a thick walled structure that supports and protects the cell. Cell wall

This cell part stores and packages materials for storage or release from the cell. Golgi apparatus

Controls what goes into and out of the cell, supports it and protects it. Cell membrane

Has powerful digestive enzymes to break down large particles of food and worn out parts of the cell. Lysosomes

Lipid bilayer Flexible membrane system that allows materials in and out of the cell

Diffusion Movement of a substance from where there is a lot to where there is a little.

PASSIVE TRANSPORT Goes with the gradient, no carrier molecules needed. No energy.

FACILITATED DIFFUSION Goes with the gradient. Uses a carrier protein. No energy!

ACTIVE TRANSPORT Goes against the gradient. Use a carrier molecule. Needs energy.

Another look at active transport

Carrier Molecules changing shape.

OSMOSIS

Hypertonic, Hypotonic, Isotonic

Exocytosis Bulk transport of materials out of the cell

Endocytosis Bulk transport of materials into the cell.
