Plant Diversity The scales of the female cones bear ovules, which enclose the female sporangia. Cells in the female sporangia also undergo meiosis to produce spores. One of the spores from each meiotic division develops into a female gametophyte by mitosis. As the pollen germinates and produces sperm nuclei by mitosis, the female gametophyte produces an egg. One sperm nucleus reaches the egg through the pollen tube and fertilizes it. Notice in Figure 6 that the male gametangium has been...

1. When you look at a pine or maple tree, the plant you see is a _____. 2. The Brazil nut tree, Bertholletia excels (n = 17), is native to tropical rain forests of South America. It is a hardwood tree that can grow to over 50 meters tall, is a source of high-quality lumber, and is a favorite nesting site for harpy eagles. As the rainy season ends, tough-walled fruits, each containing 8-25 seeds (Brazil nuts), fall to the...

Question 4 How is angiosperm fertilization different than in gymnosperms? a. Angiosperms are the only plants to produce seeds after fertilization takes place. b. In angiosperms, the female gametophyte is present on bracts. c. In angiosperms, a sperm fuses with an egg to produce a zygote. d. Unlike other plants, angiosperms require water for fertilization to take place. e. Two fertilization events take place in angiosperms, producing a zygote and endosperm.

Question 1: Please consider gametes in animals. Part a. Are gametes diploid or haploid, and what process (mitosis or meiosis) forms them? Sketch this process and include this labeled drawing in your submission. Remember that your drawing must not be an exact copy of a published figure, although you may use a published figure as a guide if you reference it. Part b. What occurs when two gametes unite, and what is the ploidy of the resulting zygote? Through which...

my assigned organism is Naked mole rat (Heterocephalus glaber). please type it. The first step in understanding how information is passed from one generation to the next is understanding how cells divide, particularly how the DNA is passed on to the resulting cells. In this discussion, you will describe the life cycle of an animal or plant of your choosing. The animal or plant you choose must have a sexual life cycle (although it may also have an asexual life...
