Alternation of generations  is a term primarily used in describing the life cycle of plants A mature sporophyte produces spores by meiosis, a process which results in a reduction of the number of chromosomes by a half. Spores germinate and grow into a gametophyte. At maturity, the gametophyte produces gametes by mitosis. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte. This cycle, from sporophyte to sporophyte (or equally from gametophyte to gametophyte), is the way in which all land plants and many algae undergo sexual reproduction.

Blog #10 Why is dissection an important part of a biology curriculum? Which animals and/or plants should be included in biological studies?

Dissection is important because it help get a greater understanding of nature around us. Dissecting is a fundamental source of learning in biology. By dissecting, we are able to find out how thing work.  Since biology is the study of life, all animals should be included (except for endangered species).

Blog#9 Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism Give an example and a picture for each

Competition is the fight for survival by fighting for necesites such as food, water, and shelter.








Commensalism is when one organism benefits while the other is unaffected.


Mutualism is when both organisms benefit from interaction.


Predation is where one organism preys on another.


Parasitism is where one organism benefits while slowly killing the organism it feeds on.
