Day 5- Plant Reproduction

Today we focused on how plants reproduce through the process of pollination. Just like humans, plants reproduce so that they have more than themselves. To do this, the plants' male and female parts need to unite in the process of pollination. Before pollination can occur, though, the plants need to attract things that can pollinate them, known as pollinators, to do that job. Plants accomplish this by having a strong scent and looking attractive with bright colors. When pollination occurs, pollen moves from the male parts to the female parts by a pollinator, such as wind or insects. During pollination, the pollen grains land on the stigma, which is the sticky substance on the top of the pistil (female part) and then goes down the tube in the pistil, the style, and reaches the ovuole for fertilization.

Once the ovuole is fertilized, it begins to turn into a seed, and that seed will eventually turn into the fruit. That fruit will contain seeds that will be scattered to start the entire process over again.

Homework for Day 5 (Friday):
For you assignment, I want you to again visit our classroom blog and post a short write-up about what you liked/disliked about the plant information we have covered so far. Are there still things that confuse you? If so, write them down. Finally, as always, comment on at least one other person's post. This assignment needs to be done by our next class period (Monday).
