| They are the oldest life form on earth. | virus |
| Most biologiests agree they are not alive. | virus |
| They are alive. | bacteria |
| They do not move, grow, or carry out respiration | virus |
| They need a living host to reproduce. | virus |
| other life forms evolved from them. | bacteria |
| Cell | smallest unit of life |
| All living things are made up of? | cells |
| nucleus | brains, tells cell what to do |
| cell membrane | allows things to enter and leave such as wter, oxygen and nutrients |
| mitochondria | might, powers the cell |
| cytoplasm | gel like - keeps parts in place |
| rough.e.r. | transports protein |
| smooth e.r. | releases calcium |
| ribosomers | makes protiesn |
| virus | a tiny particle that can reproduce only inside the cells of living things. |
| bacteria | tiny one-celled organisms, some of which can cause diseases. |
| a virus is a non living thing | true |
| bacteria a is living thing | true |
| bacteria goes through all 6 life processes | true |
| a virus does not go through all 6 life processes | true |
| what are the 6 life processes | get energy, use energy, respond to change, reproduce, grow, get rid of waste |
| get energy | plants get energy from the sun, animals get nutrients by eating other living things |
| get rid of waste | when living things use energy they produce waste |
| growing | when organisms grow they use enegy |
| reporduce | living thinggs make more of their own kind |
| resond to change | organisms resond to the environment around them |
| use energy | living things break down food material and release the store energy |
| cell wall | keeps plants sturdy and stiff |
| chlorplast | green coloring |
| red blood cells | carry oxygen |
| nerve cells | carry messages to the brain |
| mature blood cells | have no nucleus |
| skin cells | protect cells underneath the skin |
| tissues | roups of similar cells that work together to do the same job. (muscle tissue) |
| organs | composed of differnt kinds of tissues that work together.(circulatory system) |
| Which part powers the cell? | The mitochondria |
