Chapter 3 plants
Lesson 1
| Term | Definition |
|---|---|
| Chlorophyll | A green pigment found in the chloroplast of plants, algae, and some bacteria. |
| Mitochondrion | Rod-shaped cell structures that convert energy and food molecules to energy the cell can use to carry out its functions |
| Differences between plant and animal cells | plant cells have chloroplasts, cell walls, and a vacuole |
| What are the three main characteristics of all plants? | 1. Auto autotrophs 2. Multicellular. 3. Cell walls. |
| What are 2 reasons why cell walls are important for plants | 1. Cell walls separate the cell from the environment 2. Cell walls strengthens and supports the large bodies of the plant. |
| List the five things that a plant needs to survive on land | 1. obtain water in nutrients from surroundings 2. retain water 3. Support their bodies 4. Transport materials 5. Reproduce |
| Lysosomes | A small round cell structure containing chemicals that break down large food particles into small smaller ones. |
| List the two things that a plant needs, and the two things that it makes during photosynthesis | PHOTOSYNTHESIS 1. Food. 2. Oxygen. |
| vacuole | A sac-like organelle that stores, water, food and other minerals |
| Cuticle | The waxy, waterproof layer that covers the leaves and stems of most plants |
| vascular tissue | The internal transporting tissue in some plants that is made up of tube like structures that carry water, food, and minerals. |
| tissue | A group of similar cells that perform a specific function. |
| Chloroplast | An 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 when making food. |
| Photosynthesis | The process by which plants and other autotroughs can capture light energy to make food from carbon dioxide and water |
| endoplasmic reticulum | A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another |
| Organelle | a tiny cell structure that carries out a specific function within the cell |
| Chromatin | An organelle in the nucleus that contains genetic material |
| 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 parts of the cell. |
