| Question | Answer |
|---|---|
| Function of roots | absorb water and nutrients and anchor the plant |
| Pollination | when pollen moves from the male part of the flower to the female part of another plant |
| Function of stem | allows water to reach the leaves and food to reach the roots |
| Job of flower | reproduction |
| germination | process by which the embryo inside a seed begins to grow |
| Needs of living things | homeostasis, water, energy,living space |
| CO2 enters a plant through... | the leaves |
| Flowers with tall stamen and dull petals are pollinated by... | wind |
| Fertilization | the joining of a sperm cell and an egg cell in the ovary |
| Transpiration | the movement of wator vapor out of a plant |
| pollen produces | produce sperm cells |
| stomata are located on | the leaves |
| embryo | a fertilized egg |
| when a seed germinates, what emerges first | roots |
| characteristics of all plants | multicellular, cells with a nucleus & cell wall, producer |
| plant part that produces sperm cells | stamen |
| plant part that produces egg cells | ovary |
| sperm is located in the... | pollen |
| homeostasis | stable internal conditions |
| angiosperm | a plant that produces flowers and fruit |
| gymnosperm | a plant that produces seeds, but not flowers |
| fern | a vascular plant that produces spores not seeds |
| nonvascular plant | mosses and liverwort |
| reproductive structure of a conifer | pine cone |
| 3 animal pollinators | bees, bats, hummingbirds |

| does a plant die if the main stem is broken? | yes, the leaves can't get water and the roots can't get food |
| do some plants reproduce sexually? | yes, sperm and egg cells unite |
| male reproductive part of a plant | stamen |
| part of the female reproductive structure where egg cells form | ovary |
| structure that protects the developing flower | sepals |
| female reproductive part of a plant | pistil |
| flower structure that attract insects | petals |
| tip of the pistil | stigma |
| tip of the stamen | anther |
