Seeds, when compared to spores, have distinct advantages due to their hard outer shells and internal structures called endosperms, which provide essential nutrients for enclosed seedlings. Once a behavior becomes a habit we perform it much easier and faster. Heterospory and seed habit in Selaginella The occurrence of two kinds of spores in the same plant is called the heterospory. • In Pteridophytes and other lower groups, the megaspores are used to be shed and dispersed soon after their formation in order to germinate into female gametophyte. Verify your number to create your account, Sign up with different email address/mobile number, NEWSLETTER : Get latest updates in your inbox, Need assistance? A combination of these advantages gave seed plants the ecological edge over the previously dominant genus Archaeopteris, thus increasing the biodiversity of early forests.

Evolution of heterospory: successful, ü 2. What is the advantage of seed habits in seed plants. Studies have revealed that coffee, specifically, has a lot of advantages. The phenomenon of Heterospory is of great biological advantage because of the fact that a large megaspore which contains female gametophyte derives its food from the sporophyte, and is independent of the external conditions as might interfere with the growth of a free living gametophyte. This reduced the chance of genetic variability among homosporous plants. It also provides food source to the embryo. Habits are a part of your life, but don’t let them become the only thing. The seed plants (Spermatophyta) comprise two major groups: the Acrogym-nospermae (also referred to as gymnosperms; c. 800 living species) and the Angiospermae (also referred to as angio-sperms; c. 250 000 living species) (Cantino et al., 2007).
