Chapter 3 plants
Lesson 1
| Term | Definition |
|---|---|
| Describe the 3 main characteristics that all plants share? | Autotrophs, multicellular, all plant cells have a cell wall. |
| List the 2 things that a plant needs and the 2 things it makes during photosynthesis. | Sporophyte stage and gametophyte. Water and nutrients for their environment. |
| Chlorophyll | Is a green pigment found in the chloroplast of plants, algae, and some bacteria |
| Photosynthesis | Sunlight provides the energy for this food-making process |
| Tissue | a group of similar cells that perform a special function in an organism |
| Chloroplast | They look like green jelly beans and they are the structure of how food is made |
| Vacuole | A large storage sac that can expand and shrink. It stores many substances, including water, wastes and food. A plant wilts when too much water has left its vacuole. |
| Cuticle | Helps a plant reduce water loss! It’s waxy and it waterproof. |
| Vascular tissue | system of tube like structures inside the plant through which water materials in Food move. |
| Organelle | A tiny cell structure that carries out a specific function within the cell |
| Mitochondrion | Rod shaped cells 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 passageway’s in which proteins and other materials from one part of the cell to another. |
| Chromatin | Thin strands floating directly ahead in the nucleus tell the nucleus how to direct the cell |
| Lysosomes | A, small round cell structure contains chemicals that breakdown large food particles into smaller ones |
| Golgi body | A structure in the cell that receives proteins and other materials from the endoplasmic reticulum package them, and distributes them to other part of the cell |
| What are two reasons why cell wall are important for plants? | The cell wall surrounds the membrane and separates the cell from the environment |
| List the five things that a plant needs to survive on land | For plants to survive on land it must have ways to obtain water and other nutrients from their surroundings, retain water support their bodies to transfer materials and reproduce. |
| How is a plant cell different from an animal cell? | A plant cell has a cell wall but an animal cell doesn’t. |
