Discovering Plants

Roots

Are usually subterranean organ of a plant used for the anchorage to the soilBack4Flowers

A reproductive organ of the seed bearing plants .BackStem

An aerial and upright part of the plant that usually bears the leaves, flowers, and fruitsBackLeaves

a flat broad structure responsible for the production of food, transpiration, and respirationBack

How Plants Grow and Multiply and its part.Changes in a germinating seedFactors in Seed Germination and GrowthSeed and Fruit Dispersal Propagating Plants AsexuallyClick meHOW PLANTS GROW AND MULTIPLYSexual Reproduction Most plants grow from seedsThese plants have parts that are responsible in the making of seeds.These seed-making parts of plants are found in the flowers.

Are parts of a flower that are responsible in the making of seeds in floweringplantsStamen and Pistilis the male reproductive organ.Anther- ovoid structure at its tipPollen Grains- bear by antherFilament-stalk of the flower

Stamen is the male reproductive organ.Anther- ovoid structure at its tipPollen Grains- bear by antherFilament-stalk of the flower

PistilStigmaStyleOvaryOvulesAn egg cell is formed in the ovule.The ovules, after fertilization, will develop into seeds and the ovary surrounding it becomes the fruits in most plants.

Parts of a flower

For more informationClick meWhat is the Role of Pollination?

One important function of the flower is to produce seeds. but, how?If seeds are to be produced, the pollen grains from the anther must land on the stigma.

What is pollination?Is the first step in the process of development of seeds in plants.Occurs mainly by wind and by animals such as insects and birds.

Two types of PollinationSelf-pollinationWhen pollen from a plants anther is transferred to that same plants stigma.

Cross-pollinationWhen pollen from a plants anther is transferred to another plants stigma.

Fertilization and development of the seedFertilization is the union of sperm cells and egg cells.

after fertilization the ovules gradually transform into mature seeds and the ovaries into fruits.Thank you
