| A | B |
|---|
| phloem | vascular tissue through which food moves |
| xylem | vascular tissue in which water and nutrients move |
| seeds | structures that contain a young plant inside a protective covering |
| cotyledons | in some plants the one or two seed leaves that food is stored in for the embryo to grow |
| germination | early growth stage of the embryo |
| stomata | underside of the leaf's small openings, or pores |
| transpiration | process by which water evaporates from a plant's leaves |
| cambium | layer of cells inside the phloem that divide and produce new phloem and xylem |
| root cap | a structure that surrounds the tip of the root and protects the root from injury from rocks |
| embryo | young plant that develops from the zygote, or fertilized egg |
| leaves | capture light in the chloroplasts for photosynthesis |
| stem | supports leaves, stores food, transports water, food, and nutrients |
| roots | anchor plant, store food, absorb wter and nutrients |
| seed coat | protects the seed and keeps it from drying out |
| cuticle | protective waxy covering of a leaf that prevents water loss |
| lower leaf cells | contain storage area for CO2 and oxygen |
| upper leaf cells | contain the most chloroplasts for photosynthesis |
| transpiration | loss of water through the stoma of plants |
| heartwood | layer of xylem cells that no longer carry water, strengthens the stem |
| pith | center area of young tree stems that stores water |
| taproot | one main root that has some root hairs coming off it |
| fibrous root | many roots with a large number of root hairs extending from it |
| root cap | protects the root from injury as it grows through hard soil and rock |
| root hairs | increase the surface area of the root and its ability to absorb more water and nutrients |
| seed plant | reproduces with seeds and contains vascular tissue |
| vascular tissue | phloem and xylem that move water, food, and nutrients through the plant |
| seed dispersal | distributing of seeds by animals, wind, water, and shooting out of the plant |
| sapwood | active layer of the stems xylem |
| woody stem | hard stem like a tree or bush |
| herbaceous stem | soft stem like grass and flowers |
