  1. Asexual & Sexual Reproduction With Plants By David Rolke

  2. Asexual Reproduction • Asexual Reproduction means to reproduce by budding or growing small plants on roots. Or just without sex. For example strawberries grow long roots which then small strawberries grow on, but with the parent plant’s DNA. Or potatoes, which grow small sprouts which then bud, saying that the potatoes grows a smaller itself. With its own DNA.

  3. Sexual Reproduction • There are plants that have different ways to reproduce. For example there is budding. But there is also a way where plants produce pollen from the stamen which than gets carried by insects and birds, to other flowers. Which then the pollen gets stuck by pistils of other flowers. The pollen grains than grow small tubes which grow their way downward to the ovule. The ovule gets fertilized and grows into seeds.

  5. Parts of Plants • Some flowers have both genders. The male parts are filament, which contains the pollen, and the anther, which holds holds up the filament. Both of them belong to the Stamen. The female parts of the body are the stigma, where the pollen land after the flight, style which holds the stigma and the ovary, where the seeds grow after the fertilization. Those three parts belong to the pistil.

  6. Pollination • Flowers make nectar, which is food for some insects. The insect come and strafe their body against the filament. Pollen get stuck on the insects body. The bees or other insects land on the next flower and also strafe against the stigma, where small pieces of pollen grain get stuck on it. The grains of pollen then grow small tubes, which grow their way towards the ovule, to fertilize it. The ovule than grows into a seed. Then after a few weeks, the flower changes its form and the seeds travel by different ways. For example, Seeds can fly with the wind, seeds can glide downwards towards the ground, explosive where the the flowers receptacle bursts open and the seeds fly away or with water, where the seed swims away with the current. Last but not least, animals, where the seed gets caught and hangs by the animals fur.
