The type of reproduction, in which the new plant can grow from a piece of stem.
Introduction:
The reproduction can be defined as the process of producing identical offspring. The reproduction can be either sexual or asexual. The sexual mode of reproduction involves two individuals (male and female) and asexual reproduction involves a single individual.

We'd use cotton wool and dampen it, and placing the seedlings at the bottom. Depending on which bottle it was, some were mixed with dampened cotton wool, and others didn't have cotton wool that were dampened. Then the opening of the bottle was covered, except for one which was covered with a lid. (See the picture). Now, I have to explain my results in my lab report. I can't find a solid source on what factors that cause the germination of seedlings. I've covered cellular respiration, and photosynthesis, but I don't know how to proceed from here. Bear also in mind that there's no soil in which the seed is germinating, so I will have to be able to explain this. Second of all, could you clue me in on how moisture is important for the germination of seedlings? Should I also bring up the physiology of seedlings and how they're growing?arrow_forward
