More than a half from 300000 kinds of plants, have seeds reproduction. The others ways they can reproduce are from spores, rhizomes , bulbs, tubers, corns, cuttings, grafts etc.
We can find to types of reproduction asexual, where one cell can split into two cells or sexual reproduction when two cells combine and create a living cell.
We have flowers that have both reproductive organs, other flowers have only one. see flowers parts
This difference make that plants propagate themselves in different ways.
A flower garden is alive with insects that are towards nectar a substance that flowers produce. The insects carries the pollen to the next flower. The pollen grains that insects take from one flower to another, join with an egg cell and a seed may be produce. Then the ovary becomes a fruit.
Another plants need wind to spread their pollen. Tubular flowers need long tongues to pollinate. Generally are pollinated by hummingbirds or moths.
DIFFERENT PLANTS AND ITS REPRODUCTION
This trees produce corns instead of flowers. Some corn produce pollen and other produce an ovule. The small corn produce the pollen in spring, the wind carries the pollen to the large corn which has the ovule. That´s the way pollination occurs.
Are modified rhizomes. The tubers buds grow into a new plant. An example is the potato and the buds are known as potatoes eyes.
Are horizontally growing stems that are produce by plant. This plants produce adventitious roots down into the soil. Strawberries are an example.
This kind of reproduction take place in the edge of the leaves. The plant produce more plants that grow in mature ones .
Each bulb has a short stem
surrounded by nutrient leaves that gives nutrition to the stem. Bulbs grow underground.
Are similar as a bulb. It grows underground. The difference between bulbs an corms is that in corms the nutrition is stored in the stem. They don´t have leaves surrounded that provides the nutrition.
