Summary Introduction
To write:
The reason behind ocotillo not dropping its leaves at a single predictable time of each year, unlike temperate
Introduction:
Ocotillo is a hardy shrub which can tolerate high heat of up to 50 degree Centigrade and low temperature as well of up to 20 degree Centigrade. It has the capacity to withstand drought and rainless weather. It is predominantly found in desert climate and in high mountain region of 6500 ft. where there is snowfall. It is said to be dormant for years if no rain and comes back once it rains. Even a cut-down branch will grow roots if planted in a wet soil.

Which of the following is correct regarding female gametophyte development in
Angiosperms?
The female gametophyte develops in the anther
The female gametophyte develops in an ovule within an ovary
A female gametophyte develops from all four megaspores produced via meiosis
All cells of the female gametophyte are haploid
If there is a steep decline in the population of the major pollinators in an area, which of the following angiosperms would be most directly affected: aspen trees, pear trees, or dandelion plants? Why?
A slight change in a plant species’ flower structure might favor a different pollinator. How might such a change in flower structure lead to a new plant species? How does coevolution between flowering plants and animal pollinators help explain the huge diversity of angiosperms?

Absence of anything that resembles a flower This plant is probably a(n) Group of answer choices moss angiosperm protist gymnosperm fernarrow_forwardMost of the approximately 900 species of gymnosperms are conebearing plants. On the surfaces of their cone scales are ovules, which later become seeds. These ovules are said to be naked because they are not completely enclosed by diploid tissue (as the ovules of angiosperms are). This characteristic gives the gymnosperms their name; gymnos is a Greek word meaning naked, and sperma means seed. Botanists now divide the gymnosperms into four groups: conifers, cycads, ginkgos, and gnetophytes.arrow_forwardWhile out on a hike you happen on to a small herbaceous plant that is currently producing many colorful flowers and seeds. The seeds that this small plant is producing have large wings that blow long distances in the breeze. Which of the following is most likely true of this plant?
