| Germination | seed starts to grow a stem and leaves break |
| Seed Coat | this part of a seed protects the embryo from injury and also from drying out. |
| Endosperm | This is a temporary food supply |
| Embryo | This is a tiny plant |
| Cotyledons | These are seed leaves |
| Coro | is an example of a monocot seed |
| Beans | is an example of a dicot seed |
| Annual | The stem may stay alive like trees, it completes it's life cycle in one season grows seed flowers |
| Marigolds, tomatoes | examples of annual plants |

| Daisies | example of a perennial plant |
| Biennial | two seasons, rest in winter, starts to grow in the spring |
| Carrots | Example of a biennial plant |
| 3 things a seed needs to grow | sun, water, carbon dioxide |
| 2 things a ROOT does for a plant | absorbs water and nutrients |
| 2 things a STEM does for a plant | carries water and nutrients to the leaves |
| 2 things a LEAF does for a plant | it makes food and absorbs sun |
| 2 things a FLOWER does for a plant | makes seeds and pollen |
| Fruit | it contains seeds |
| 4 things a seed needs to survive | water, nutrients, carbon dioxide, and sun |
| Photosynthesis | The process by which plants make there own food |
| 5 things a plant needs to make its own food | sun, water, glucose, CO2, and Chlorophyll |
| Chlorophyll | Cell that makes glucose |
| What a plant gets from the soil | nitrogen, potassium, phosphorus nutrients and water |
| Most important plant nutrients that they get from the soil | Nitrogen, Potassium, Phosphorus |
| Leaves | Collect the sunlight that is used for photosynthesis |
| Flower | Part of the plant that makes seeds |
| Pollination | moving pollen from the anther to the stigma |

| 2 ways that a plant has adapted to live in a water | under water leaves are flexible to go with the current some plants have airspaces in there stems |
| Monocot | Sees that has one cotyledon |
| Herbaceous stem | it is not made out of wood |
| Fibrous root | doesn't have a lot of root thin strands |
| Why are plant at the bottom of the food chain | people and animals eat plants |
| What would happen to animals if all the plants in the world die | animals would die - no fool/habitat |
| 5 ways plants help the environment of humans | make food, make oxygen, habitats for animals, move and help soil, produce |
| Bees help pollinate flowers | pollinate flowers by taking from one flower to the next |
| Birds help pollinate flowers | get nectar and move between flowers |
| Why are orangutans and pandas endangered animals | people cut down trees and destroyed their habitats |
| 2 ways that animals help disperse seeds | eat them or bury them |
