| Term | Definition |
|---|---|
| Chlorophyll | A green pigment found in the chloroplasts of plants, algae and some bacteria |
| Photosynthesis | Sunlight provides the energy for food making process, a plant uses carbon dioxide gas and water to make food and oxygen |
| Tissue | Tissues are groups of similar cells that perform a specific function in an organism |
| Chloroplast | Look like jelly beans are structures in which food is made |
| Vacuole | Large storage sac that can expand and shrink, stores water, wastes and food |
| Cuticle | Helps a plant reduce water loss and is waxy and waterproof layer |
| Vascular tissue | A system of tube like structures inside a plant through which water minerals and food move |
| Organellee | A tiny cell structure that caries out a specific function within the cell |
| Chromatin | These strands contain genetic material the instructions for for directing the cells functions |
| 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 passageways in which proteins and other materials are carried out to another |
| Lysosomes | A small round cell structure containing chemicals that that break down large food particles into smaller one |
| Golgi body | A structure in a cell that receives proteins |
| Three characteristics that all plants share | Autotrophic, except some green algae, Contain many cells, all plants have a cell wall |
| 2 things that a plant. needs & 2 things it makes during photosynthesis | They make food and water during photosynthesis.They need carbon dioxide and water |
| 2 reasons why cell walls are important for plants | The cell wall surrounds the cell membrane and separates the cell from the environment |
| 5 things a plants needs to survive on land | Water, to obtain nutrients ,retain water, support their surrounding, transport materials, and reproduce |
| Label a plant cell diagram and why its different from an animal cell | Plant cells have a cell wall chloroplasts and a large central vacuole animal cella do not have these things |
