Every living thing has cells. It is the basic functional unit in humans. Humans are multi cellular organisms, which roughly have trillions of cells in the human body. They all play an important role in various bodily functions.
They form the body’s structure, take in and transport nutrients from foods to the host, convert nutrients to energy, and carry the genetic materials of the body. The cell, though extremely minute does have different parts on it.
| Nucleus | Regulates all cell activities |
| Cell Membrane | Is made out of phospholipids and proteins |
| Mitochondrion | Site of cellular respiration “power house” |
| Lysosome | Suicide Sacks that contain digestive enzymes |
| Rough Endoplasmic Reticulum | Contains Ribosomes, transports proteins and other materials |
| Smooth Endoplasmic Reticulum | Contains no ribosomes, stores proteins |
| Gogi complex (apparatus) | Processes and packages proteins |
| Nucleuolus | Dark spot of chromatin in the nucleous where ribosomes are produced |
| Cytoplasm | Colloid that contains water and nutrients and supports the organelles |
| Organelles | The parts of a cell with a particular function |
| Prokaryotic | Cells with no true nucleus and no membrane bound organelles |
| Eukaryotic | Cells that contain a true nucleus and membrane bound organelles |
| Centrioles | Only in animal cells, aid in cell division |
| Ribosomes | Produce Proteins |
| Chloroplast | Found only in plants, site of photosynthesis |
| Vacuoles | Large storage sacks found mainly in plants |
| Cell Wall | Structure in plants made of cellulose that is outside of the cell membrane |
| Chromatin | Thin strands of DNA and proteins found in the nucleus of a cell. |
| Cell | Smallest unit of life |
| Cytoskeleton | Long protein filaments in the cytosol that support the cell. |
