Asexual Reproduction

Asexual ReproductionBy Ainesh Jain

Starfishes can reproduce asexually and sexually. they reproduce asexually by fission. They split in half and both grow back the missing parts.

Daughter CellsWhen a cell is ready to reproduce, the cell splits into two cells. Those two cells that are produced are called daughter cells. The daughter cells initially have half of the DNA the parent cell did.

Hydras can reproduce asexually and sexually. When food is plentiful hydras reproduce asexually by growing a mini hydra on the side. When it is mature, it breaks off.

How Does it Happen?When a cell is getting ready to divide, the nucleus splits. When the nucleus splits, the chromosomes split as well and go to the poles of the cell. Lastly, the cytoplasm splits and two cells are formed.

What reproduces asexually?Many types of organisms use asexual reproduction to reproduce. Some plants and animals do this. Twins happen the same way. The egg splits into two and you get twins.

ClonesWhen asexual reproduction happens, the daughter cells are exact clones of the parent cells. The daughter cells do not get genes from more than one source so, there is no variation. So, the daughter cells have the exact same genotype as the parent cells.

The Spider Plant produces plantlets on its buds to reproduce asexually.

Question 2Offspring born from one parent is an exact clone of the parent. Offspring born from two examples have genes from both parents and thus are not clones but a little different than either one of their parents. So the clone has no variety and the sexually reproduced offspring has variety form parents. For example, corals that are clones are many times different than corals that were sexually reproduced. Also clones do not have the protection from parasites that is getten from "variety genes" like they showed in the video.

Question 1The benefits of asexual reproduction are that the organism can do it by itself and faster. One starfish doesn't have to find another one and therefore the process is faster. The drawbacks are that you can sometimes only do it in good conditions. Hydras can only bud when they have a lot of food. Another drawback is that there is no variety in offspring because they are all clones.

Corals can reproduce asexually and sexually. Asexually, they produce by new corals budding off of parent corals.
