The advantage of heterospory is that it facilitates the evolution of different plant species. It has numerous benefits, including decreased genetic variability, and an increased reproductive efficiency. In addition, heterosporous plants tend to advance to seed habitats sooner than homosporous plants. Here are some advantages of heterospory. Read on to learn about these advantages. Once you’ve read this article, you’ll be more knowledgeable about this important topic.
Heterospory is a form of reproductive strategy used by many plants, including ferns, and mosses. While this type of reproduction system produces fewer seeds per plant, it takes longer for seeds to mature. This reduces the diversity of species within ecosystems. It also makes the offspring more susceptible to disease and insect damage. In contrast, microgametophytes produce only one type of spore, the microspore.
In addition to being more efficient at generating seeds, heterosporous plants can produce two distinct types of gametes. They may also improve the reproductive capacity of both male and female species. They may be more susceptible to disease than homosporous species, because heterosporous sporophytes have more space to grow. In summary, these advantages of heterospory make it a popular choice among crop-grown plants. However, it has many disadvantages.
The first advantage of heterospory is the ability to store pollen. As it is easier to disperse and travel, heterosporous plants can grow larger than homosporous ones. As a result, the size of the gametophytic generation is reduced. In Pteridophytes, homospores only differ in archegonia and antheridia, which are important for sex differentiation.
Heterospory also improves reproductive health. Its male sporophytes need a continuous supply of food and oxygen to sustain their growth. In contrast, heterosporic plants can produce two kinds of stomata – the former has megaspores, while the latter has microspores. During meiosis, the microspores increase in size, while the megaspores grow out. This is a major advantage of heterospory compared to the former.
The second advantage of heterospory is that it is possible to predict sex at the spore stage. The resulting microspores produce fewer spores, and the male is reduced to an antheridium. The resulting spores are both independently self-supporting in terms of food and energy. And the reproductive advantages of heterospory go beyond sex diversity. It is more advantageous to plant species, and humans.
Biologically, heterospory is beneficial in that it can help plants survive in the harsh climate of arid regions. As a result, the female gametophyte is independent of external conditions and has the highest survival rate of the three types of seedlings. The third advantage of heterospory is that the sporophyte is more resistant than the female, and it is also more fertile. This means that the chances of reproducing independently of the sporophyte are much higher.
