Life can find its way in almost any conditions that exist on Earth. To do this, there are many different ways of reproduction. And an important role in the formation of numerous biocenoses is played by the reproductive cell of animals and plants - the gamete.
general information
First of all, you need to understand the terminology. What is a gamete in biology, and what role does it play? This is how reproductive (reproductive) cells are designated, the peculiarity of which is the presence of only half of the chromosome set and association during reproduction. Together they form a zygote. There are male and female gametes. The former are called sperm, and the latter are called egg cells.
With a lack of knowledge, a question may arise about how this applies to plants. The reason for this is simple: in plants, sperm are pollen. And female eggs are contained in the ovary of plants. A gamete is formed by cell division.
Why is the reproductive cell of animals and plants important?
First of all, this is reproduction. But why in this way? The fact is that we have to exist in a world built on competition. Many different pathogenic bacteria and viruses want to settle in our body and use its resources. This is largely possible thanks to the "selection of keys" to our DNA.
Therefore, in order to ensure the survival of the organism, a mechanism was developed during evolution that provided for the release of half of deoxyribonucleic acid, which stores information about a person, animal, or plant. Thus, the effect of harmful microorganisms on the offspring is becoming more complicated.
This is an important mechanism for the struggle of large organisms for a place under the sun on this Earth, because our competitor is an adversary who has great ability to adapt. That is why such a reproductive cell of animals and plants as the gamete is important.
