| A | B |
|---|
| diffusion | when molecules enter a cell by way of the selectively permeable membrane from an area of higher concentration to an area of low concentration |
| osmosis | when water molecules "diffuse" |
| passive transport | transport that does not requires energy |
| active transport | transport that requires energy |
| facilitated diffusion | when a molecule cannot enter a membrane and enters by way of a carrier molecule |
| transport proteins | proteins in the cell membrane that pick up molecule outside the cell and carry them in, using energy |
| give examples of active transport | englufing and transport proteins |
| a cell membrane is... | selectively permeable |
| What does the cell theory state? | That 1) all cells have come from previous cells, 2)all cells are the structure and function of living things, 3) all living things are composer of cells |
| What organelle is the "powerhouse for the plant" by turning food into energy? | mitochondria |
| what dark green structures trap light energy and produce it into food? | chloroplasts |
| Why is the nucleus centered in the center of the cell? | So it can direct all cell functions out. |
| What are two organelles only found in plant cells? | chloroplasts and cell wall |
| What organelle is larger in the plant cell than in the animal cell? | vacuole(s) |
| What are the Golgi bodies for? | They receive proteins and other newly formed materials from the ER and package and distribute them to other parts of the cell. |
| What do animal and plant cells have that bacteria cells do not? | a nucleus |
| What is an element? | any substance that cannot be broken down into simpler substances |
| What is an atom? | the smallest unit of an element |
| What is a compound? | When two or more elements combine together. |
| What is a molecule? | The smallest unit of most compounds. |
| What are carbohydrate's structure? | ring-like |
| Why do we need carbs? | FOR ENERGY!!! YAAA :) |
| what are carbs made up of? | hydrogen, carbon, and oxygen |
| What is an organic compound? inorganic compound? | organic-has carbon, inorganic-doesn't |
| what are proteins' structure? | long chain of amino acids |
| what do proteins produce that speeds up chemical reactions? | enzymes |
| what is a proteins' elements? | carbon, hydrogen,oxygen, nitrogen |
| what are the nucleic acids' structure? | twisted ladder, double helix |
