| Word | Definition |
| Cell Membrane | A thin structure that surrounds both animal and plant cells, its main job is to control what enters and leaves the cell (door man). |
| Cell Wall | Plants cells – the area outside the cell membrane, it is a stiff structure that helps support and protect the |
| Nucleus | This organelle controls the cell, it is known as the “brain” of the cell, or mayor of the town. |
| Cytoplasm | A jellylike substance that make up all the living material in a cell except the nucleus. |
| Mitochondrea | Structures that are the powerhouse of the cell (produce power). |
| Ribosomes | An organelle that manufactures and moves materials within a cell. They look like small dots on the Golgi bodies and float freely in the cytoplasm (cars). |
| Endoplasmic Reticulm | An organelle that transports (moves) materials throughout a cell (Highway). |
| Golgi Bodies | An organnelle that manufactures and moves materials within a cell (Shipping/ Fed. Ex). |
| Lysosomes | An organelle that break down food molecules, waste products, and old cells (trash service). |
| Vacuoles | An organelle that stores food, water, and wastes in a cell and helps get rid of wastes (warehouse). |
| Chloroplasts | Plant cells have green, oval-shaped organelles that help with photosynthesis. |

What you need to know for th BIG EXAM: PARTS OF THE CELL nucleus cell membrane mitochondrion tissue golgi body ribosome endoplasmic reticulum organ cytoplasm cell wall organelle chloroplast organ system* cell theory* virus* MICROSCOPE PARTS eyepiece low-power objective coarse adjustment knob diaphragm high-power objective mirror arm fine adjustment know base stage clips revolving nose piece stage MICROSCOPES compound light micoscpoe electron microscope PLANT CELL cell wall nucleous cell membrane chomatin endoplasmic reticulum ribosome cholorplast vacole golgi complex mitochondrion ANIMAL CELL golgi complex cell membrane endoplasmic reticulum nucleous chromatin lysosome ribosome mitochondrion food vacuole NOTES A cell is the smallest unit that is capable of performing life functions. A nerve cell can be a meter long. The human egg cell is smaller that the dot on the i. Prokaryotic cells- without membrane bound structures Eukaryotic cells- with membrane bound structures The cells of different types of plants are in cell walls. The eye is the most important of all 5 sences. The 1st man to make a microscope was not a trained scientist.
