You all spend all your time jerking off and talking bout japanese cartoons. Time to learn some cool stuff instead.

What is sexual reproduction?
Sexual reproduction is a means or propagation that came about because it has the advantage of genetic variation; where as an asexual species just clones it self, sexual species combine their genes, most genes are inactive in a specimen, and so offspring not only has a random mix of the two parents genes but also genes that their great great grandparents might have had and combinations of genes that no other specimen has had. In sexual species this genetic variation allows adaptation to different environments or changing environmental conditions (the speed of this adaption is set by the average lifespan and average age of reproduction of the species). For instance adaption to northern climates by humans led to decrease in melanin in the skin due to genetic variation and the specimens with less melanin surviving more often (because deficiency in vitamin D weakens immune system), this is called evolution. Darwin gave the more classic example of birds that are forced to a new island due to an eruption, and on the new island the seeds are slightly bigger, this means that the birds born with larger beaks survive more and over a few generations all specimens have larger beaks. This is an example of how genetic variation drives adaption to new environments and it is why sexual species are so common compared to asexual species.

What are angiosperms and gymnosperms?
Gymnosperms are the older form of tree, they reproduce by opening pine cones and the seeds gets spread by the wind to female pine cones that are inseminated by it. Angiosperms are a lot younger and came about during the Cretaceous (the latter period of the dinosaur era which is called the Mesozoic). Angiosperms are flowering plants, they produce a flower which has sugar on it (nectar), an insect eats the nectar and in the process has pollen rubbed on them by the Stamen if it is a male flower, when they go to eat the nectar of a female flower from another specimen of the same species of plant, they get the pollen on the female flowers Stigma, the flower will then turn into a fruit, the fruit is eaten by a mammal or an avian which then moves on and defecates out the seeds within the fruit, the seeds then grow into a new plant using the defecation as fertiliser.

What is Fungi?
Fungi are an order of life alongside plants, animals, and bacteria. They usually live in the soil or inside plants and they propogate with spores. You are likely breathing in fungus spores now. If you bake some bread and immediately rush to put it in an airtight container, it will still go moldy. The mold was not in the wheat, it simpyl is in the air everywhere all the time and so the spores got on it when you took the bread out of the oven!
Fungi eat decaying plant matter, parasitize plants, or make mutual exchanges with plants. The majority of plant specimens have a mutual relation with a fungi, in that the fungi gives the plant phosphorus and other nutrients and in exchange the plant gives the fungus carbohydrates. What does fungi look like you ask? Fungi is most often seen as what is called Mycelium, mycelium are branching strands called hyphae that look like fine white roots that spread in the soil or perhaps under bark, anywhere it won't dessicate, some families of fungi make frutiing bodies which we know as mushrooms, toadstools, and truffels. These are the result of reproduction between two fungi species which reproduce by fusing their hyphae, the fruting body then grows and spread the spores. Many species of fungi including mold are capable of asexual reproduction also. Fungi is at least as old as vascular plants and likely older in aquatic species.

What are primates?
Primates are a group of mammals that evolved to have dexterous hands to peel fruit, unfortunately this adaptation has led them to be able to "masturbate", many species of primates have nearly went extinct since they just masturbate all day instead of reproducing, nature has had to make the female of the species extremely horny compared to other species in order to force the males to reproduce with them (epic win).
