| Question | Answer |
| cell | the smallest unit that can perform all life processes |
| How were cells discovered? | looking at a cork tree |
| What is the cell theory? | -all organisms are made up of one or more cells
-the cell is the basic unit of living things
-all cells come from existing cells |
| How are cells, atoms, and molecules alike? | very small, made-up of smaller parts, all within humans, can't see them with the naked eye, make up all living, non-living things, make up other things |
| How are cells different form other particles? | -makes up living things
-basic unit of life
-can perform life processes
-made up of organelles
-can reproduce |
| How are atoms different from other particles? | -makes up non-living things
-basic unit of matter
-can bond
-made up of protons, electrons, and neutrons
-can not reproduce |
| How are molecules different from other particles? | -non-living things
-basic units of compounds
-made up of atoms
-doesn't reproduce |
| structure | arrangement of parts in an organism. Includes shape and material made up of. (How its made) |
| function | the special, normal, or proper activity of an organ or part of an organ (The job it does) |
| organelle | structures inside a cell |
| nucleus | large organelle in a eukaryotic cell that contains DNA |
| DNA | hols info on how to make a cell's protein |
| proteins | control chemical reactions in cells |
| nucleolus | where the cell begins to make its protein |
| cell wall | only in a plant cell; a rigid structure that provides support for the plant cell |
| cell membrane | covers the cell surface and acts as a barrier (semipermeable) |
| cytoplasm | made mostly of water holds |
| energy processing | how the cell produces energy |
| ATP | Adenosine Triphosphate |
| chloroplast | -2 membranes
-own DNA
-where photosynthesis takes place
-contains chlorophyll
-captures energy
-organelle in plant and algae cells |
| Who built the first microscope and was able to identify a cellwall in cork? | Robert Hooke |
| mitochondria | -only in animal cells
-release energy as ATP
-function is to change energy from food that cells can use
-sugar is broken down to produce energy (glucose)
-mainly found in muscle cells |
| Examples of an organelle is... | nucleus, nucleolus, cell wall, cell membrane, and cytoplasm |
| ulva | -a green protist that looks like a head of lettuce |
| volvox | -green algae plants that looks like bubbles. |
