Plant Unit
| Question | Answer |
|---|---|
| Bryophyte | A small flowerless green plant of the division Bryophyta, which comprises the mosses and liverworts. |
| Pteridophyte | A member of the Pteridophyta, a division of plants including the ferns and their allies (horsetails, club mosses). |
| Gymnosperms | A plant that has seeds unprotected by an ovary or fruit. Gymnosperms include the conifers, cycads, and ginkgo. |
| 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. |
| Monocot | A group of flowering plants of Angiospermae (angiosperms), characterized by having only one cotyledon in the seed and an endogenous manner of growth. |
| Dicot | Any member of the flowering plants, or angiosperms, that has a pair of leaves, or cotyledons, in the embryo of the seed. |
| Germination | Germination refers to the process by which an organism grows from a seed or a spore. Germination occurs primarily in plant and fungal species. (Always used water) |
| Embryo | An unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus). |
| Cotyledon | An embryonic leaf in seed-bearing plants, one or more of which are the first leaves to appear from a germinating seed. |
| Seed Coat | The protective outer coat of a seed. |
| Taproot | A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward. |
| Fibrous Root | A fibrous root system is the opposite of a taproot system. It is usually formed by thin, moderately branching roots growing from the stem. |
| Osmosis | Movement of water from a higher concentration to a lower concentration through a semipermeable membrane |
| Root Hair | Each of a large number of elongated microscopic outgrowths from the outer layer of cells in a root, absorbing moisture and nutrients from the soil. |
| Xylem | The vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem. |
| Root Pressure | Root pressure is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. |
| Cohesion | The action or fact of forming a united whole. |
| Adhesion | The action or process of adhering to a surface or object. |
| Phloem | The vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves. |
| Glucose | A simple sugar which is an important energy source in living organisms and is a component of many carbohydrates. |
| Transpiration | (of a plant or leaf) The exhalation of water vapor through the stomata. |
| Photosynthesis | The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. |
| Stomata | Any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width which allows movement of gases in and out of the intercellular spaces. |
| Guard Cell | open/close Stomata |
| Chloroplast | Organelle where photosynthesis takes place (Captures energy from sunlight and uses it to produce food for the cell. Contains the chemical chlorophyll.) |
| Chlorophyll | Green chemical in Chloroplast |
