(Metaphyta) A kingdom that includes all the plants. The earliest true plants were probably unicellular green algae, which first appeared in the Precambrian.
(vascular plants; kingdom Plantae)
A division comprising plants that have vascular tissues (xylem and phloem) through which water and nutrients are transported.
The division of the plant kingdom (Plantae) that includes all of the seed-producing plants. These form two groups, the gymnosperms and the angiosperms (flowering plants).
CA seed plant in which the ovules are carried naked on the cone scales, in contrast to the angiosperms, in which they are enclosed by an ovary.
A flowering plant, distinguished by producing seeds that are enclosed fully by fruits. Angiosperms are the most highly evolved of plants, and appear first in rocks of Lower Cretaceous age.
A division of the plant kingdom, comprising the vascular cryptogams. They are flowerless plants exhibiting an alternation of 2 distinct and dissimilar generations. The first is a non-sexual, spore-bearing, sporophyte generation Like Ferns
Succulent or herbaceous
Fleshy non-woody plants usually shortlived.
Any wiry or woody, free-hanging, climbing plant. (vines aren’t woody)
1 Refers to the propensity of a cell, its components, or its products to become stained by an acidic dye. “acid-loving” plants
Applied to a cell, its components, or products that can be stained by a basic dye. (base or Ph loving plants)
Three lifecycle patterns exist among higher plants…
Annuals, biennials, or perennials the lifecycle consists of :seed germination, vegetattion and reproduction, then death.
Applied to a plant that lives for two years. During the first season food may be stored for use during flower and seed production in the second year. If the plant is damaged, for example by insect attack, it may survive into a third year and flower again.
A plant that normally lives for more than 2 seasons and, after an initial period, produces flowers annually.
A straight-chain, insoluble polysaccharide that is composed of glucose molecules linked by beta-1,4 glycosidic (see glycoside) bonds. It is the principal structural material of plants, and as such is the most abundant organic compound in the world. It has also been found in certain sea squirts.
