Q:
With these anatomical features in mind, do research to find
an angiosperm species that has structural modifications to leaves, stems,
roots, or flowers that result in adaptive functions. For example, a California
Barrel Cactus has spines in place of leaves to reduce water loss
Discuss the following in your answer:
1.Identify the angiosperm species and describe the
structural modification.
2.Explain how this specific structural modification
(adaptation) to leaves, stems, roots, or flowers helps the plant to live and
survive in its environment.
Cant use:
California Barrel Cactus, Dandelions, Venus Fly trap, Albany
Pitcher trap, Sundew, Black Needlerush, Evergreen Shrub, Marijuana, Aloe Vera, Fishhook
Cactus, or Sunflowers

Preview: ... rticular ways. The sexual organs (pistil and stamens) of the orchid flower are fused together into a structure called the column, which lies opposite the lip. Orchids have only one stamen (male floral organ), and in most orchids it bears only one anther (pollen-producing structure); in a few orchids, however, two anthers are produced. The pollen is not granular, as it is in most flowering plants, but is aggregated together in a number of masses, or sacs, that vary in texture from mealy to horny. Three stigmatic lobes (pollen-receptive areas) are usually pres ...

Botanists group species of plants (or, from the other direction, the monocots and dicots can be subdivided) based on a number of characteristics. Botanists pay particular attention to how the flowers are put together:
A complete flower has all four layers of parts.
An incomplete flower lacks one or more layers. These knotweed flowers lack petals (corolla).
A perfect flower had both “sexes” — both stamens and pistil(s). A monoecious plant has perfect flowers or has both male and female flowers on the same plant (for example, Easter lily, pea, dandelion, and rose).
An imperfect flower is lacking e ...
