*its shape and size contribute to its function
Robert Hooke

Cell theory
1.All organisms are made up of one or more cells
2.Cells are basic units of structure and function in all living things
3.All cells come from cells that already exist
Organelle
a tiny sructure in the cell that performs a funtion
Nucleus
directs all cell activities (similar to the brain of the cell)
Nucleolus
makes ribosomes
Chromatin
Contains DNA (genetic material that are the instructions for the cell)
cell membrane
selectively permeable membrane meaning it only lets specific materials move in and out of the cell
Cytoplasm
gel-like material inside the cell -cytosol is part of the cytoplasm
Endoplasmic recticulum
moves material around in the cell (like a highway)
Ribosomes
make protiens and translate messages
Golgi Body
the packaging organelle
Mitochondria
powerhouse of the cell because it breaks down food molecules and releases energy *does cellular respiration
Vacuole
storage area in the cell
