plant characteristic
plant characteristics key terms
| Term | Definition |
|---|---|
| Alternation of Generations | The fluctuation between the diploid (sporophyte) and haploid (gametophyte) life stages that occurs in plants. |
| Alternation of Generations | The fluctuation between the diploid (sporophyte) and haploid (gametophyte) life stages that occurs in plants. |
| Angiosperm | A vascular flowering plant in which seeds are enclosed inside of protective ovaries. |
| Autotroph | An organism that synthesizes its own organic nutrients and does not rely on other organisms for food. |
| Bryophyte | A lower terrestrial plant (often a moss or liverwort) that lacks a vascular system and is dependent on environmental moisture for reproductive and nutritive functions. |
| Bulb | Roughly spherical underground bud containing additional buds that can develop asexually into new plants. |
| Chlorophyll | A green pigment, necessary for photosynthesis, that is found in the chloroplasts of plants. |
| Dicot | An flowering plant (angiosperm) that possesses two cotyledons during embryonic development. |
| Diploid | Having two sets of chromosomes, one from each parent. |
| Gamete | A haploid sex cell (either an egg or sperm cell); male and female gametes join during fertilization to create a diploid zygote. |
| Gametophyte | A haploid plant or plant structure that produces haploid gametes through mitosis. |
| Grafting | An artificial form of vegetative propagation in which parts of two young plants are joined together, first by artificial means and then by tissue regeneration. |
| Gymnosperm | A vascular non |
| Haploid | Having only one set of chromosomes. |
| Hormone | A chemical that affects the ways in which an organism functions; it is produced in one part of the plant body but, by traveling to target cells throughout the body, affects many other parts as well. |
| Jacket Cell | A component of the cell layer that covers the reproductive organs of plants and prevents them from drying out. |
| Monocot | A flowering plant (angiosperm) that possesses one cotyledon during embryonic development. |
| Ovary | In plants, the protective structure that holds the ovules and surrounds the angiosperm seed; after fertilization, develops into a fruit. |
| Ovule | Structure that contains the female gametophyte and gametes; after fertilization, develops into a seed. |
| Phloem | Vascular tissue composed of cells that are living at maturity; transports the products of photosynthesis throughout the plant body. |
| Photosynthesis | The process by which plants and other autotrophic organisms convert light energy into organic materials. |
| Pollen Grain | The male gametophyte of gymnosperms and angiosperms. |
| Root | The part of a plant beneath the soil; responsible for collecting water and minerals from the soil, storing nutrients, and securing the plant to the ground. |
| Root Hair | An outgrowth of a plant root that provides an increased surface area for the absorption of water and dissolved minerals from the soil. |
| Runner | Slender horizontal stem that can give rise, via specialized nodes, to new plants. |
| Shoot | The part of the plant above the soil, including all aerial structures such as stems, leaves, flowers, and fruits; gathers carbon dioxide and light energy for photosynthesis, provides surfaces for gas exchange, and contains the plant's reproductive organs. |
| Sporophyte | A diploid plant or plant structure that produces haploid spores through meiosis. |
| Stoma | A very small epidermal pore, surrounded by two guard cells, through which gases diffuse in and out of a leaf. |
| Tracheophyte | A terrestrial plant with a vascular system. |
| Tuber | Fleshy underground storage structure, composed of an enlarged portion of the stem, that has on its surface buds capable of producing new plants. |
| Vascular System | Mechanism of internal water and nutrient transport, made up of the vascular tissues xylem and phloem, that is characteristic of tracheophytes. |
| Vascular Tissue | A conductive component (either xylem or phloem) of the system that transports food and nutrients throughout the plant body. |
| Vegetative Propagation | A form of asexual reproduction in which plants produce genetically identical offshoots (clones) of themselves, which then develop into independent plants. |
| Xylem | Vascular tissue composed of cells that are dead at maturity; transports water and dissolved minerals upwards from the roots to the shoot. |
| Alternation of Generations | The fluctuation between the diploid (sporophyte) and haploid (gametophyte) life stages that occurs in plants. |
| Antheridium | The male sex organ of terrestrial plants; where sperm cells are generated. |
| Archegonium | The female sex organ of terrestrial plants; where egg cells are produced. |
| Autotroph | An organism that synthesizes its own organic nutrients and does not rely on other organisms for food. |
| Diploid | Having two sets of chromosomes, one from each parent. |
| Epidermis | The outer layer of cells found on the body wall of an organism. |
| Gamete | A haploid sex cell (either an egg or sperm cell); male and female gametes join during fertilization to create a diploid zygote. |
| Gametophyte | A haploid plant or plant structure that produces haploid gametes through mitosis. |
| Haploid | Having only one set of chromosomes. |
| Jacket Cell | A component of the cell layer that covers the reproductive organs of plants and prevents them from drying out. |
| Photosynthesis | The process by which plants and other autotrophic organisms convert light energy into organic materials. |
| Root | The part of a plant beneath the soil; responsible for collecting water and minerals from the soil, storing nutrients, and securing the plant to the ground. |
| Shoot | The part of the plant above the soil, including all aerial structures such as stems, leaves, flowers, and fruits; gathers carbon dioxide and light energy for photosynthesis, provides surfaces for gas exchange, and contains the plant's reproductive organs. |
| Spore | Haploid cell from which a gametophyte is produced. |
| Sporophyte | A diploid plant or plant structure that produces haploid spores through meiosis. |
| Stoma | A very small epidermal pore, surrounded by two guard cells, through which gases diffuse in and out of a leaf. |
