The lower animals like protozoans, sponges and few coelenterates reproduce in one simple way while all the rest follow a different pattern of reproduction. How do penguins reproduce? female, contributes half of the offspring's genetic makeup. Some species of gecko reproduce asexually, when the female produces fertile eggs without mating with a male. Although giraffes do not have a mating season, it is more common during the rainy season because they are less stressed out and there is plenty of food to consume. A female can produce thousands of eggs, which she stores in her ovary.

Although they cannot fly, they are still birds that reproduce laying eggs, only that the incubation time, the number of eggs and the care devoted to … Meiosis is a two-part cell division process in organisms that sexually reproduce which results in gametes (egg and sperm) with one half the number of chromosomes of the parent cell. Before fertilization, the entire interior of the egg consists of a single cell, which can weigh up to 5 pounds. Most ferns reproduce sexually, and that involves meiosis and fertilisation. Once they are sexually mature, their sex organs acquire the necessary conditions to reproduce, but they can begin to mate later. Should other males try to come into contact with her they will battle. In captivity, they mate throughout the year as they do not have shortages of food or water. The largest cells found in nature are ostrich eggs. What did Castiglione do? This can result in one of the males dying in the process. Jellyfish reproduction involves several different stages. This is why most zoos often have a male and a female or two females instead of two males. Usually, land snails reach maturity between 6 … When you are thinking of the typical big fern plant, what it does is, by meiosis, produces spores, and spores have half the number of chromosomes of the big parent plant. ; Each spore grows into a photosynthetic prothallus (gametophyte) via mitosis.Because mitosis maintains the number of chromosomes, each cell in the prothallus is haploid. ... What does it mean to reproduce sexually? I How do plants reproduce asexually? II Where do our crops come from? Perpetuating the species is a paramount issue for any animal, and penguins are no exception. Trending. The Ostrich egg will weigh 1600 – 2300 gm (about 3.5 to 5 pounds) and is equivalent in volume to 2 dozen chicken eggs. 1. Individuals reach sexual maturity at different ages, according to their species and their particular conditions. In the adult, or medusa, stage of a jellyfish, they can reproduce sexually by releasing sperm and eggs into the water, forming a planula. However, there have been documented cases of male elephants engaging in sexual activities on each other due to their urge to reproduce but not being able to do so for a lack of available females to them. ...

When food supplies are very low, and they struggle to survive are less likely to breed.
