Chapter 3 Plants
Chapter 3 Lesson 1
| Term | Definition |
|---|---|
| Chlorophyll | A green photosynthetic. Pigment found in the chloroplast of plants, algae and some bacteria |
| Photosynthesis | The prosses by witch plants and other autotrophs capture and use light energy to make food from carbon dioxide and water |
| Tissue | a group of similar cells that preform a specific function |
| chloroplast | an organelle in the cells of plants and some other organisms that captures energy from sunlight and changers it to an energy form that cells can use in making food from carbon |
| Vacuole | A sac-like organelle that stores water food and other materials |
| Cuticle | the waxy waterproof layer that cover the leaves and stems of most plants |
| Vascular tissue | The internal transporting tissue in some plants that is made up of tubelike structures that carry water food and minerals |
| Organelle | A tiny cell structure that caries out a specific function within the cell |
| Chromatin | The strains called chromatin connect genetic material the instructions for directing the cell’s function |
| Mitochondrion | Rod- shaped cell structures that convert energy in food molecules to energy the cell can use to carry out its functions |
| Endoplasmic reticulum | A cell structure that forms a maze of passage ways in witch proteins and other materials are carried from one part of the cell to another |
| Lysosomes | a small round cell structure containing chemicals that break down large food particles into smaller ones |
| Golgi body | A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum packages them and distributes them to other part of the cell |
| What are the 3 main characteristics that all plants have | multicellular, autotrophs, cell wall |
| 2 things that a plant needs and the 2 things it makes during photosynthesis | plants need: obtain water and other nutrients They produce: transport materials and reproduce |
| What are the 2 reasons why cell walls are important for plants | Plant cells are enclosed by a cell wall And separates the cell from the environment And plant cells walls contain cellulose witch makes the walls rigid witch is good for crunch like a carrot |
| List the 5 things that a plant needs to survive on land | Obtaining water and other nutrients retaining water support transporting materials reproduction |
| label a plant cell diagram and why its different from a animal cell | Plant and animal cells are different because an animal cell doesn’t have chlorophyll and a vacuole |
