Term | Definition |
---|---|
Vascular plants | Plant has veins to transport water and nutrients. |
Non-vascular plants | Plant does not have veins to transport water and nutrients. |
Cuticle | A protecting film covering the epidermis of leaves |
Plant embryo | A plant in the early stages of development: in higher plants, the plumule, cotyledons, and radicle within the seed. |
Stomata | Permit the absorption of carbon dioxide necessary for photosynthesis from the air, as well as the removal of oxygen. |
Root cap | A section of tissue at the tip of a plant root. |
Cambium | The tissue that allows the plant to get wider. |
Xylem | Carries water and nutrients up the stem to all parts of plant. |
Phloem | Carries food for the plant. |
Bulbs | Underground food storage - stores food over the winter and provides a new plant with food until it can make its own. Have thick fleshy ‘layers’. |
Fibrous root | Roots that branch out from stem and get water from the surface of the earth. Usually found in monocots. |
Tap root | One main root that grows downward with smaller roots branching out. Get water form deep in the water. Usually found in dicots. |
Tubers | Underground food storage - stores food over the winter and provides a new plant with food until it can make its own. |
Herbaceous stem | soft, green - usually found on flowering plants |
Woody stem | strong, inflexible - usually found in trees and bushes |
Guard cell | Open and close the stomata. |
Palisade layer | Contains chloroplasts, which is where photosynthesis takes place |
Seed coat | The protective outer coat of a seed. |
Epidermis | “Skin” of leaf - responsible for gas exchange |
Spongy layer | Between the palisade layer and lower epidermis; it contains vascular tissue and has air spaces for gases to pass through |
Cotyedon | an embryonic leaf in seed-bearing plants, one or more of which are the first leaves to appear from a germinating seed. |
Angiosperm | a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees. |
Gymnosperm | a plant that has seeds unprotected by an ovary or fruit. |
Stigma | The part of the pistil where pollen germinates. |
Style | A long, slender stalk that connects the stigma and the ovary. |
