| Term | Definition |
|---|---|
| Chlorophyll | a green pigment found in the chloroplasts of plants, algae, and some bacteria |
| photosynthesis | a process which plants and other autotrophs use light from the sun to make food |
| tissue | Group of similar cells that preform a specific function |
| chloroplast | organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food |
| vacuole | sac-like organelle that stores water, food, and other materials |
| cuticle | Waxy waterproof layer that covers the leaves and stems of most plants |
| vascular tissue | tissue in some plants that is made up of tubelike structures that carry water, food, and materials |
| organelle | a tiny cell structure that carries out a specific function within the cells |
| chromatin | Strains in genetic material/ DNA |
| mitochondrion | rod shaped cell structure that convert energy in food molecules to energy that cells can use to carry out its functions |
| endoplasmic reticulum | cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of a cell to the another |
| lysosomes | a small round cell structure containing chemicals that break down large food partials into smaller ones |
| Golgi body | structure in a cell that receives proteins and other newly formed materials from the endoplasm reticulum packages them and distributes them to other parts of the cell |
| 3 main characteristics that all plants share | Autotroph’s, organisms to produce their own food, cell wall |
| 2 things that plants need and the 2 things it makes during photosynthesis | Water, sunlight and sunlight, food |
| What are two reasons why cell walls are important for plants | it keeps the cell safe and it separates it from the environment |
| List five things that the plant needs to survive on land | Ways to obtain water and other nutrients from their surroundings, retain water support their bodies, transport, material, and reproduce |
| Three differences between a plant cell and an animal cell | Cell wall, chloroplast, vacuole |
