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
