Heredity increases diversity among organisms by nonrandom mating, which is the preference of the organism to mate with another based on specific characteristics. Nonrandom mating has two forms. Inbreeding is the first form where organisms with the same genotypes will mate with each other resulting in minimal genetic diversity. Outbreeding is the second form where organisms of different genotypes will mate with each other resulting in an increase in genetic diversity. The variation in the heredity of an organism allows it to be more flexible and can also guarantee better survival rate of the population under the given environmental conditions.
<span>sporophytes
</span><span>A sporophyte produces spores therefore those plants that have spores is called sporophyte. A sporophyte is a type of a diploid organism so, which means that meiosis must occur in order to be able to produce haploid cells containing half number of chromosomes. Meiosis in sporophyte occurs in an area called sporangia. The spores that are being created inside sporangia shall be release into the air. Mitosis is expected to take place on a single haploid spore in order to be a multicellular gametophyte.</span>
The feature that allows this to happen is a semipermeable membrane (selectively permeable membrane). This allows the cell to decide what gets in, it allows things like hydrocarbons and oxygen and water to pass, but prevents large sugars from getting in. The process of water passing through the holes in osmosis which is the diffusion of water across this semipermeable membrane.
