Cell Structure- Shea
pre-test cell structure
| Question | Answer |
|---|---|
| cell membrane | outer boundary of the cell, which allows for material to enter and exit |
| cell wall | supports, protects and gives shape to a cell |
| chloroplasts | capture light energy from the sun and convert it to a chemical energy for the cell |
| chromatin | hereditary material made from DNA and proteins and is located in the nucleus. contains all the information for the cell |
| cytoplasm | gel-like material made of water and other chemicals |
| cytoskeleton | network of protein filaments that provides shape and internal organization |
| ER | folded membrane that carries proteins and other materials around the cell. can be smooth or rough |
| golgi apparatus | receive proteins and other materials from the ER and then packages and distributes them to other parts of the cell |
| lysosomes | small organelles which contain chemicals that digest waste and worn out cell parts |
| mitochondria | convert energy in food molecules to energy the cell can use to carry out its functions |
| nucleus | directs all activity of the cell |
| ribosomes | makes proteins and can attach to the ER or float on their own |
| vacuoles | fluid-filled storage centers for food, other materials and waste. Plants have one large one. Some animals cells have small ones; other animals cells have none |
