- The movement of a plant in response to the force of gravity
- When a root system forms a single primary root
- The process where dissolved minerals are transported into a plant
- Polysaccharides produced by root cells which lubricates the tip and eases its journey through the soil
- Fleshy roots found on bulbs or corms which shrink during prolonged droughts thus pulling the bulb or corm lower
- Small single cell extensions of epidermal cells that are the primary site for the absorption of water.
- A root systems composed of several seminal roots
- A plant whose roots do not require contact with soil
- 1. Specialized body parts ( cones, roots, and flowers)2. Pollen to carry sperm cells3. Rigid cell wall of cellulose and lignin 4. Waxy covering ( cuticle ) to prevent H2O loss
- Monocots - 1 cytoledon, flower parts in 3's, and parallel leaf veins Dicots: 2 cytoledons, flower parts in 4's or 5's, branched/ net leaf veins
- Nonvascular: gametophyte( dominant) and don't have xylem or phloem Vascular: sporophyte ( dominant ) and have xylem and phloem
- Eukaryotic Multicellular Autotrophic Cell wall of cellulose
- Perennial(live for a number of years), vascular(contain xylem and phloem), stem persists across seasons and years, and secondary thickening(expansion in girth).
- Trees convert carbon dioxide and water into sugars, storing carbon in their cell walls.
- - Sieve tube elements and companion cells work together to transport carbohydrates. - Fibers provide additional support - Phloem parenchyma cells
- - Bryophytes (nonvascular plants)- Seedless vascular plants - Gymnosperms - Angiosperms (flowering plants)
- - Simple tissues: one kind of cell - Complex tissues: two or more kinds of cells.
- examples of leaf specialization in relation to ecological roles
- What percentage of plant species are engaged in mycorrhizal symbiosis?
- A woody plant that produces seeds and fruits, with leaves with branching, net-like veins, and pollen with three aperatures (openings) is most likely a member of which group? A. conifersB. cycadsC. eudicotsD. monocots
