Answer:
Name the two types of flowers. How are they different?
Different types of flowers (the Angiosperms) can easily be identified by dividing them into Monocots or Dicots. ... There are other ways of classifying flowers, especially Annuals; Perennials, Biennials and Ephemerals; or even by the way they reproduce such as Sexual Reproduction and Asexual Reproduction eg. Bulbs.
What do you understand by pollination?
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
ANS .1 FIRST FLOWER:. This Portulaca has narrow leaves and the petals are not clearly defined. Because the leaves look like Monocots (not branching), I would have assumed that this was a Monocot. But it is definitely a Dicot Flower as you can see below with the broader leaved form. It is a good example of just how tricky Nature can be. The photo below is much clearer. If you click on it to enlarge it you can see the five petals distinctly. Sometimes, unless you have access to the original baby seed leaves of a flower, things can get pretty tricky.
SECOND FLOWER : Portulacas (above) are often called Moss Roses. They are Dicots because they have combinations of five petals. The singles have five petals and the doubles may have ten or more. But they do look so much like Wild or Single Roses that it's easy to see how they came to be considered Moss Roses. (The true Moss Rose is an actual Centifolia Rose). See more about them on the Portulacas Page. Here you will see just why these hardy, drought tolerant little plants are so popular.
