CELL STRUCTURE STUDY GUIDE

1. Nucleus- control center of the cell, directs all cell activities
2. Cell Membrane- gatekeeper of the cell, allows some things to move or out but not all things.
3. Mitochondria- the energy source of the cell, the power generator, site of respiration
4. Vacuole- storage area for the cell- stores, water, wastes, oxygen and food
5. Endoplasmic reticulum- transport system of the cell.
6. Ribosomes-place where proteins are made
7. Golgi Bodies- packages proteins and gives support
8. Chloroplasts- makes food for the plant cell, changes solar energy into chemical energy

 
The main differences of the plant and animal cell are:

PLANT	ANIMAL
Contains cell wall	No cell wall
Box-like shape	Roundish shape
Large vacuoles	Small vacuoles
No centrioles	centrioles
Lysosomes are rare	Lysosomes are many
chloroplasts	No chloroplasts

 
 
CELL THEORY:

1.  All organisms are made of one or more cells
2.  All cells come from other cells
3.  A cell is the basic/smallest unit of life that carries on all life’s processes
