Term | Definition |
Chlorophyll | a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. |
dicot | a flowering plant with an embryo that bears two cotyledons (seed leaves). Dicotyledons constitute the larger of the two great divisions of flowering plants, and typically have broad, stalked leaves with netlike veins (e.g., daisies, hawthorns, oaks). |
vein | A vein is a vascular structure (xylem and phloem cells surrounded by the bundle sheath) in a leaf that provides supports for the leaf and transports both water and food. The veins on monocots are almost parallel to the margins of the leaf. |
cuticle | a protective and waxy or hard layer covering the epidermis of a plant, invertebrate, or shell |
root | In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil. Roots can also be aerial or aerating, that is growing up above the ground or especially above water. |
pollen | a fine powdery substance, typically yellow, consisting of microscopic grains discharged from the male part of a flower or from a male cone. |
xylem | the vascular tissue in plants that conducts water and dissolves nutrients upward from the root and also helps to form the woody element in the stem. |
stem | the main body or stalk of a plant or shrub, typically rising above ground but occasionally subterranean. |
monocot | a flowering plant with an embryo that bears a single cotyledon (seed leaf). |
pollination | the transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization. |
chloroplast | (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place. |
germination | the development of a plant from a seed or spore after a period of dormancy. |
seed coat | the protective outer coat of a seed. |
seed | a flowering plant's unit of reproduction, capable of developing into another such plant. |
conifers | a tree that bears cones and evergreen needlelike or scalelike leaves. Conifers are of major importance as the source of softwood, and also supply resins and turpentine. |
leaf | a flattened structure of a higher plant, typically green and bladelike, that is attached to a stem directly or via a stalk. Leaves are the main organs of photosynthesis and transpiration. |
sprout | shoots of a plant. |
spore | (in a plant exhibiting alternation of generations) a haploid reproductive cell that gives rise to a gametophyte. |
phloem | the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves. |
taproot | a straight tapering root growing vertically downward and forming the center from which subsidiary rootlets spring. |
cotyledon | an embryonic leaf in seed-bearing plants, one or more of which are the first leaves to appear from a germinating seed. |
