INTRODUCTION
By playing, living ensure the survival of the species. There two distinct types of reproduction:
1) ASEXUAL . It is characterized by a single parent is involved giving rise to new individuals are alike to him. Asexual reproduction is characteristic of bacteria, algae, protozoa, fungi, some plants and animals
2) SEXUAL REPRODUCTION . It is characterized involves two types of sex cells (gametes) that, in most cases are produced by two parents (one male and one female). Individuals that are produced are not identical to their parents because they have characters of both. Sexual reproduction is characteristic the vast majority of animals and plants ..
WHAT IS KNOWN FOR CYCLE OR LIFE CYCLE? . The life cycle of a living being is the set of stages that any living through since it is the egg cell or zygote until it becomes an adult. Any
cycle consists of the following phases:
a) REPRODUCTION . Sex cells or gametes produced by the agencies come together to form the zygote.
b) EMBRYONIC DEVELOPMENT. Once formed, the zygote, it will suffer a series of divisions to form a complete individual
c) GROWTH . Once formed the body, there will be increased in size and maturity of the same to get the features of an adult can be replayed.
CURIOSITIES. You've probably heard about the reproduction of the seahorse (also called the hippocampus). Here you can watch a video showing the birth of these animals. Remember that it was truly "rare" in the reproduction of these animals? if you are able to explain in few words, add a comment on this post which sums it up. If you see a comment that there are already exposed but you think you can comment on or otherwise explain it form or rectify because you think that something is not right, do not hesitate to do so.
WORK FOR THIS ITEM.
After studying the issue, attend to the explanations and participate actively in class, you will make a presentation on "IMPRESS" with your partner (specifications to be met are the same as for any presentation, ie, text short but clarification of what we are studying, meaningful images to help understand our exposure and generally ingeniárosla to make it as attractive as possible.)
