Chapter 3 Plants
Lesson 1
| Term | Definition |
|---|---|
| Chlorophyll | A green photosynthetic pigment found in the chloroplast of plants, algae, and some other bacteria. |
| Tissue | A group of a 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 in making food. |
| Vacuole | A sac-like organelle that stores water, food, and other materials. |
| Cuticle | The waxy, waterproof layer that covers the leaves and stems of the most plant. |
| Vascular tissue | The internal transporting tissue and 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 cell. |
| Chromatin | Contain genetic material, the instructions for directing the cell’s function. For example, the instructions in the chromatin ensure that leaf cells grow and divide to form more leaf cells. |
| Mitochondrion | Rod-shaped cell structure 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 passengeways in which proteins and other materials are carried from one part of the cell to another. |
| Lysosomes | a small, round cell structure containing chemicals that break down large food particles into smaller ones. |
| Golgi body | a structure in a cell that receives protein and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell. |
| Describe the 3 main characteristics that all plants share. | Nearly all plants are autotrophs, organisms that produce their own food. With the exception of some green algae, all plants contain many cells. In addition, all plant cells are surrounded by cell walls. |
| List the 2 things that a plant needs in the 2 things it makes during photosynthesis. | a plant uses carbon dioxide gas and water to make food and oxygen. |
| What are 2 reasons why cell walls are important for plants. | Contain cellulose, a material that makes the walls red. Because their cell walls are rigid, plant cells look like small boxes. |
| List the 5 things that a plant needs to survive on land. | for plants to survive on land, they must have ways to obtain water and other nutrients from their surroundings, retain water, support their bodies, transport materials, and reproduce. |
| Label a plant cell diagram and why it’s different from an animal cell. | one has a larger vacuole, one doesn’t have a cell walls (animal cell), and the other does(plant cells), one has chloroplasts(plant cell) and the other doesn’t(animal cell) |
