Term | Definition |
Weed | A plant growing where it is not wanted. |
Crop | A plant that is raised for the production of food and/or fiber for people or animals. |
Botany | The study of plants |
Paleozoic Era | More than 500 million years ago |
Ordovician Period | 505-438 million years ago |
Angiosperms | The flowering plants |
Cretaceous Period | About 355 million years ago |
Vascular | Structural support, water conduction |
Phloem | Food conduction. Roots, stems, and leaves |
Nonvascular | Mosses, no more than 1 or 2 inches tall. No special tissues like xylem and phloem. |
Cell Wall | Protects, structurally supports cells |
Chloroplast | Specializes in photosynthesis |
Central Vacuole | Increases cell surface area, stores metabolic wastes |
Nucleus | Keeps DNA and its transcription into RNA away from potentially damaging reactions in cytoplasm |
Nuclear Envelope | PART OF NUCLEUS- double membrane perforated with pores that control the flow of materials in and out of the nucleus |
Nucleolus | PART OR NUCLEUS- a small round body of protein in a cell nucleus, where ribosomes are made, synthesized and partially assembled |
DNA in Nucleoplasm | PART OF NUCLEUS- Chromatin: holds hereditary material |
Ribosomes | Attached to rough ER and free in cytoplasm sites of protein synthesis |
Rough ER | Modifies new polypeptide chains; synthesized lipids |
Smooth ER | Diverse roles; e.g. makes lipids, degrades fats, inactivates toxins |
Golgi Apparatus | Modifies, sorts and ships proteins and lipids for exports or for insertion into cell membranes |
Lysosome- Like Vesicle | Digests, recycles materials |
Plasma Membrane | Selectively controls the kinds and amounts of substances moving into and out of the cell; helps maintain cytoplasmic volume and composition |
Plasmodesmata | Communicates junction between adjoining cells |
Mitochondrion | Energy power-house produces many ATP or aerobic respiration |
Cytoskeleton | Structurally supports, impacts shape and moves cell and its componants |
Microtubules | PART OF CYTOSKELETON- Hollow tubes of protein that support the cell and moves organelles within the cell |
Micofilaments | PART OF CYTOSKELETON- Protein fibers that help the cell contract and move |
Intermediate Filaments | PART OF CYTOSKELETON- Threadlike proteins in the cell's cytoskeleton that are roughly twice as thick as microfilaments |
Tonoplast | Holds vacuole together |
Peroxisome | Where hydrogen peroxide and other harmful molecules are broken down by enzymes |
Alternate | Leaf arrangement, one leaf at each node of the stem |
Annual | A plant whose life duration is a year or less. |
Awn | A bristle-like tip: most frequently used with respect to bristle or hair like projections from glumes, lemmas, or paleas of grass spikelets. |
Berry | A fleshy, several-seeded fruit. |
Biennial | A plant whose life is two years. |
Bulb | An underground perennial, storage organ consisting of a stem axis and numerous, overlapping leaf scales. |
Capillary | Thread-like. A small tube that helps draw water. |
Compound (leaf) | A leaf whose blade is divided into two or more distinct leaflets. |
Dissected (leaf) | A leaf whose blade is cut into numerous, narrow lobes. |
Entire | The margin of a leaf which is untoothed. |
Fibrous Roots | A root system, as in grasses, compound of numerous, separate roots rather than one main root. |
Infloresence | A cluster of flowers, or the flower-bearing portion or portions of a plant. |
Internode | Portion of a stem between nodes. |
Irregular | A flower with petals which differ in size. Example: Flowers of the legume family. |
Leaflet | A secondary division of a compound leaf. |
Margin | Edge of a leaf. |
Node | The part of the stem from which leaves and branches arise. |
Opposite (leaves) | The leaves paired at each node. |
Palmately Compound | A compound leaf in which the leaflets all arise from the same point |
