| cell wall | only found in plants, it supports and protects the cell. |
| cell membrane | it is full of holes and allows only certain materials in and out of the cell. |
| cytoplasm | a gel-like material that fills the inside of the cell. |
| nucleus | it controls all activities in the cell. |
| nuclear membrane | it surrounds the nucleus and allows only certain materials in and out of the nucleus |
| vacuoles | stores food, water, and waste products in the cell. |
| mitochondria | the powerhouses of the cell, they release energy from food. |
| endoplasmic reticulum | they are the transportation tunnels of the cell. they move materials around inside the cell |
| ribosomes | this is the place where proteins are made for the cell |
| chromatin (chromosomes) | they contain the codes for making new cells. the word means colored bodies |
| lysosomes | this structure is used to digest material in the cell |
| golgi bodies | this is where proteins are packaged to leave the cell |
| chloroplasts | found only in plant cells, these structures trap sunlight to create food for the plant. |
| nucleolus | this is found in the nucleus and this is where ribosomes are made. |
| capsule | in a bacteria cell, this is the layer of slime that surrounds the cell wall |
| flagella | this structure allows bacteria to move around in their environment |
| nucleoid | this is an area in bacteria cells where the DNA is concentrated |
| tissue | a group of similar looking cells that do the same sort of work |
| organ | a structure made up of different types of tissue that work together to do a particular job |
