Cell Parts and Cell Parts

Cell Wall

Cell Wall

A rigid layer that protects and supports the cell

Cell Membrane

Help the organisms move

Nucleus

Controls the whole cell, inside is the chromatin which is made of DNA and RNA

Mitochondria

Makes energy available to the cell

Chloroplast

Capture sunlight energy to make food

Vacuoles

Stores and transport materials in the cell

Unicellular

Organisms with one cell

Multicellular

Organisms with more than one cell

Cell Theories

-cells are the smallest unit of life, meaning they are the basic units of life -all living organisms are made of cells, meaning from the smallest organisms to the largest they all have at least one cell -all cells come from existing cells, meaning cells don't just form randomly, they are divided from other cells

Homeostasis

maintaining a constant internal environment

nuclear membrane

surrounds the nucleus

nucleolus

found inside the nucleus, makes ribosomes

lysosomes

breaks down matter in the cells

prokaryotic

do NOT have a nucleus

Eukaryotic

cells that DO have a nucleus

golgi apparatus

packages and moves things within the cell, delivers to correct place

smooth endoplasmic reticulum

produces lipids, moves things through the cell

rough endoplasmic reticulum

contains ribosomes

animal cell

does not have a cell wall or chloroplast and a small vacuole

plant cell

contains a cell wall, chloroplast and large vacuole
