Cell Theory test

The Cell Theory

All living things are made of cells. Cells are the basic unit of structure and function in all living things. New cells are produced from existing things

Bacteria

Cells without a nucleus.

Eubacteria

Cells without a nucleus that resemble eukaryotes

Eukaryotic kingdoms

Animals, plants, fungus, and protists

Prokaryotes

NO NUCLEUS. 2 major categories are bacteria and eubacteria

Eukaryotes

Have a nucleus and internal membranes. Can be bacteria and eubacteria

Cell Membrane

a thin flexible barrier around the cell

Cytoplasm

the area outside the nucleus, but inside the cell membrane

Cell Wall

provides support and protection

Ribosomes

Produce proteins from codes from the nucleus

Nucleus

found in only Eukaryote cells only. Contains info of DNA

Chromatin

Instructions for the cell (DNA)

nucleolus

produces ribosomes

Nuclear envelope

membrane surrounding the nucleus

Cytoskeleton

A network of proteins that help the cell maintain its shape, helps with the movement of materials and organelles throughout the cell.

RoughER

covered in ribosomes which makes it looks rough.

SmoothER

no ribosomes

Golgi apparatus

packages, sorts and ships materials throughout the cell

Lyosomes

sacs filled with enzymes that break down food particles and old organelles

Vacuoles

Store water and food and help support structures (plants)
