The gametophyte stage of the plant life cycle is most conspicuous in ___. A. Ferns B. Seed plants C. Horsetails D. Mosses E. Club mosses D. Mosses How are gametes produced by bryophytes? A. By meiosis of sporophyte cells B. By meiosis...
In plants, offspring are the seedlings that result from the fertilization of the ovules by the pollen of the plants. In animals, the offspring are the young, or children that are produced.Answer and Explanation: Young plants and animals are similar to their parents ...
as they help the plants reproduce. Wind and water carry the pollen grains to other plants. Birds and insects are attracted to the color and scent of the flower. As they flit from one flower to another, pollen grains get stuck in their bodies and are then transported to other flowers...
How can an organism be produced with out gamete formation in asexual reproduction? Summarize the process by which the male and female gametes are brought together. Why is this process referred to as double fertilization? Is t...
Meiosis, a unique way to produce gametes: Meiosis, a special type of cell division, is essential for sexual reproduction. The cells produced by meiosis are called gametes (in higher animals) or spores (in flowering plants). Male gametes are also known as sperm; female gametes are known as ...
The ovaries produce steroid hormones. The follicular part of the ovary mostly produces estrogen. Also, androgen and progestin are produced in the follicular part of the ovary. The ovaries function cyclically. One of the follicles while maturing becomes dominant and prevents others from maturing. The...
The impact of conflict on the evolution of organismal biology changes in response to how organisms reproduce3. For sea urchins or abalone, which cast their gametes to the whims of ocean currents, conflict shapes the interface between sperm and eggs4,5. For organisms with internal fertilization, ...
Zoospores b of brown algae a can be positively deposited on the surface of the cathode and a rocky place for marine algae with high adhesion density can be produced. The direct current is 0.05-5.0mA/m<2> in the case of zoospores of sea tangle and 0.001-10.0mA/m<2> in the case of ...
According to Carl Sagan in "The Dragons of Eden": Large organisms such as human beings average about one mutation per ten gametes [a gamete is a sex cell, either sperm or egg] -- that is, there is a 10 percent chance that any given sperm or egg cell produced will have a new and ...
How to determine possible gametes for a genotype How do you find the genotypes on a pedigree? What genotype does a person with O blood have? What is genotype? What would the genotype ratio of the offspring be for two individuals that are heterozygous?
