Asexual Reproduction:

translation:

1. Parent individual

2.Fragmentation

3.The star will regenerate the lost arm

4.Of the fragment a new star will appear (replica)

The process by which a living being generates another living being of the same species. A form of reproduction that occurs without the fusion of sexual cells. In other words, it generates offspring that is identical to a single parent. There is many different types of asexual reproduction, such as binary fission (throat bacteria), budding (hydra, sponge), fragmentation (sea star), vegetative reproduction (strawberry, potatoes), or spore formation (fungi, bacteria).

Binary Fission: single cell splits in identical copies.

Budding: where a new individual develops from some generative anatomical point of the parent organism.

Fragmentation: a piece of organism or cell breaks and the piece grows again like a clone of the parent.

Vegetative Reproduction: specific cells that develop to structures that forms a new plant like the parent.

Spore Formation: single cell that grows and changes to a different organism.

Advantages:

1.) Energy is not required to find a mate

2.) Large colonies are produced

3.) Many offspring are produced

4.) Diversity facilitates the adaptation of the species to environmental changes.

Disadvantages :

1.) Offspring are genetic clones susceptible to the same disease.

2.) Unfavourable conditions can wipe out entire colonies

3.) Some offspring that are close together compete for food and space

Sexual Reproduction :

Advantages:

1.) It removes bad genes from the population.

2.) More genetic variation species.

3.) Able to produce more offspring because of mate.

Disadvantages :

1.) It requires two parents, a male and a female.

2.) It produces fewer offspring than asexual reproduction.

3.) It requires energy and time, slower reproduction rate.

Mitosis and Meiosis

There is two different process on which the cells divide from the chromosomes,  one is mitosis and the other is meiosis.

What is Meiosis?

Meiosis consists of two successive divisions, meiosis I and meiosis II, and its process is like PMAT, but twice. Is the basis for sexual reproduction. It requires two parents. Basically,meiosis is the production of gametes that contain half the number of chromosomes from a body cell. Each body cell has 46 chromosomes, where half come from the father and half from the mother. We call these cells HAPLOID. The difference from mitosis is that in Meiosis, it creates a variation on the species. As I said before, there is two phases o meiosis: meiosis I and meiosis II. Now I am going to explain the phases of meiosis I and meiosis II.

What is Mitosis?

Mitosis is the process that produces two identical daughter cells from one parent cell. Mitosis is used in asexual reproduction. Also Mitosis is one of the shortest phases of cell cycle, why? It only consists on prophase, metaphase, anaphase and telophase. And it is a duplication of a cell and all of its parts. It duplicates the DNA.

What is the difference between Mitosis and Meiosis?

Mitosis is a method of cloning; from a progenitor cell we obtain two descendant cells with the same genetic information and equal to the genetic information of the progenitor cell. In meiosis, four daughter cells genetically different from each other, and different from the progenitor cell, are the basis of sexual reproduction.

How do organisms grow:

Lets start with the basics, Mating is the process by which gametes arrive in the same place at the same time, there are 2 main types of fertilization: Internal, where the sperm and egg unite inside the body of parents. External, where sperm and egg unite outside body of parents. Some methods of fertilization are that there must be enough nutrients for the dividing embryo, and temperature must be warm enough so protients and enzymes still function properly during chemical reactions in developing embryos. Pollination is the transfer of pollen to a plant for fertilization, its transfered by bees, buterflies, moths. The embryo develops in the female part. Now we have embryonic development, and is when the embryo is formed and develops.It has 4 stages: cleavage, patterning, differentiation and growth.

Here is a briefly example of how organisms grows in butterflies.

Extra Info:

1.) How does the cell differ between plants and animals? In plants, a cell plate forms between the daughter cells.

2.) The cell needs to have enough nutrients, DNA must be replicated, and DNA should not be damaged to go through the cell cycle.

3.) The life of a cell is divide in 3 stages: interphase, mitosis, and cytokinesis.

4.) What is the difference between reproduction cloning and therapeutic cloning? Well, the purpose of reproduction cloning is to make a genetic duplicate of an existing organism or a dead organism. And the purpose of therapeutic cloning is to correct problems of health, like diabetes, Parkinsons disease, or spinal injuries.

5.) The purpose of DNA replication is to make an identical copy of DNA, and its process its like this. The DNA molecule unwinds, enzymes separate the DNA molecule, each side of the ladder is a template on which a new side forms, and finally, the new bases pair with the bases of the original DNA,

6.) Cancer cell growth has large abnormal nucleus, they move to new locations, and they are unspecialized.

7.) The cell cycle has 3 stages: interphase, mitosis and cytokinesis, and its just about division and duplication of the cell.

After doing this post and doing this review, I think that it helped me understand better what we were doing and how interesting is mitosis, meiosis, asexual and sexual reproduction, how cells grow, and how it all connects! At the very beggining I was really confused, but now I do understand a lot more. I also think that it was really good watching all the videos and doing the activites with the posters, that helped me a lot to understand better.But I would like to learn a little bit more about how organisms grow, like, get more detailed information.
