Chapter 3 plants
lesson one
| Term | Definition |
|---|---|
| Chlorophyll | a green pigment found in the chloroplast of plants,algae, and some bacteria. |
| photosynthesis | the process by which plants and other autotrophs capture and use light. |
| tissue | a group of similar cells that preform a specific function. |
| chloroplast | captures energy-from sunlight |
| vacuole | sac-like organelle stores water, food and other materials |
| cuticle | the waxy waterproof layer that covers the leaves/stems of most plants |
| vascular tissue | the intense tube-like structure that carries food/water/ minerals |
| Organelle | tiny cell structure that carries out a specific function within the cell |
| chromatin | the complex DNA of other proteins |
| Mitochondrion | power house of plant cells generates ATP through cellular respiration (ENERGY) |
| endoplasmic reticulum | involved in the synthsis of protiens and lipids |
| Lysosomes | A small round cell structure containing chemicals that break down large food particles into smaller ones |
| Golgi | sorts , modifies, and packages protein’s and lipids for transport |
| describe the 3 main characteristics that all plants share | autotrophs, multicellular, and cell walls |
| list the 2 things that a plant needs and the 2 things it makes during photosynthesis | carbon dioxide and water |
| what are the 2 reasons why cell walls are important for plants. | they separate the cell from the enviornment , they are rigid, provide protection and support |
| List the 5 things that a plant needs to survive on land | water, food , support their bodies, transport materials ,and reproduce |
| Compare animal cell to plant cell | animal is usually a heterotroph but plants are usually autotrophs |
