| seed | a structure that can grow into a new plant |
| embryo | a young organism that is just beginning to grow |
| flower | a plant structure where seeds are made |
| pollination | when pollen moves from the male part of a plant to an egg after which a seed can form |
| fruit | plant structure that grows around seeds |
| life cycle | how an organism grows and reproduces |
| cone | a plant structure where seeds are mde in some nonflowering plants |
| germinate | begin to grow |
| seedling | a small plant |
| From Seed to Plant | 1. A seed is planted in soil. 2. The seed germinates. Roots start to grown down in the soil. 3. The roots grow longer - a stem pushes up out of the ground. 4. The plant grows leaves and starte to make its own food. 5. In time, the plant grows into an adult. Now it can reproduce and make new seeds. |
| flowering plants | plants that use flowers to make seeds |
| pollen | powder produced by the male part of the flower |
| egg | the female part of the flower |
| nectar | sweet liquid from the flower that bees are attracted to and drinkk |
| decompose | when the adults plants die, they break down and become part of the soil |
| conifer | plants that reproduce with cones |
| spores | plant structure that are used to reproduce in plants that do not make seeds (fern) |
| bulb | an underground stem |
