| cytoplasm | contains all the cell parts |
| organelles | "little organs" each performs its own specific function |
| nucleus | control center for the cell |
| chromatin | genetic blueprint of the cell |
| nucleolus | ribosomes are assembled |
| nuclear envelope | encloses the contents of the nucleus, double membrane performed with pores |
| ribosomes | proteins are assembled |
| endoplasmic reticilum | network of membranes that produceand transport materials |
| rough er | proteins are made and transported |
| smooth er | lipids are made and transported |
| golgi apparatus | packages and distributes materials from ER (proteins and lipids) |
| vesicle | sac that contains an organic compound |
| mitochondrion | supplies energy (from food) to cell |
| peroxisome | contains enzymes to alter dangerous chemicals in cells |
| centrioles Animal only | aids in cell division |
| lysosome Animal only | cleans up the cell, contains digestive enzymes to rid the cell of unwanted materials |
| cytoskeleton | supports and shapes the cell |
| flagellum Animal only | long whiplike tail |
| cilia | many short flagella |
| vacuole | stores water, nutrients, enzymes: variety of functions |
| central vacuole plant only | large area in plant cells, keep plant cells rigid, contains water and digestive enzymes |
| chloroplast plant only | uses energy from sunlight to make food in the form of sugar |
| cell wall palnt only | support around some cells, very porous; contains cellulose |
| cell membrane | determines what enters and leaves the cell (selectively permeable) |
