What are the benefits of bees collecting honey for sage?

The flowers of green plants are divided into two categories: unisexual flowers and bisexual flowers. Unisexual flowers include male flowers and female flowers. Male flowers are flowers with only stamens, which only produce pollen and cannot bear fruit; Female flowers only have pistils, which can only accept pollen and fruits. Androgyny means that there are both pistils and stamens in the same flower.

Common billing plants are: cucumber, pumpkin, watermelon, cantaloupe, gourd, corn and so on.

Plants with bisexual flowers are: beans, soybeans, tomatoes, eggplant and so on.

2. Lily is hermaphrodite, hermaphrodite.

1。 Salvia is a labiatae plant. It has a labial corolla with a pistil and two stamens under the upper lip. The stamens are T-shaped and have a unique structure, just like two levers arranged side by side at the entrance of the flower tube. When the honeybee stepped on his lips and put his head into the flower tube to eat honey, the lower end of the T-shaped stamen was pushed inward by the insect's head, and the upper end drooped due to leverage, just hitting the anther on the back of the honeybee, so that the pollen was scattered. When this bee flies to another flower to collect honey, as soon as its back touches the stigma of the drooping pistil, it will pass the pollen to the stigma of that flower by the way.

2. Male flowers are terminal, small, simple in structure, without bright colors, with degenerated perianth, slender filaments, T-shaped anthers that are easy to shake, thin and dry pollen, and feathery stigma. Completely adapted to wind-borne pollination.

3. In order to ensure the complete hybridization of plants without self-pollination. Ensure the purity of future generations.

4. Ensure that pollination is artificial and prevent self-pollination; Prevent cross-pollination and prevent confusion and loss; Ensure the normal breathing of flowers.

5. Because there is no pollination or the pollination effect is poor, there is no growth hormone to stimulate the growth during the seed expansion period, which leads to the lack and shrinkage of seeds.

6. Pollination and fertilization are not good. Do artificial pollination and rub the two flower heads of sunflower face to face. Shake the corn in the field or knock down the pollen and sprinkle it on the corn beard.

7. Each ovule needs two sperm to fertilize the egg cell and polar nucleus respectively. When the flower is in full bloom, the pollen on the anther will adhere to the stigma due to the action of wind or insects, and the pollen grains will grow pollen tubes, pass through the stigma and reach the ovule along the style. Each pollen grain germinates and produces two sperm in the pollen tube. The pollen tube enters the ovule through the micropyle, releases the sperm, and combines with the egg cell and polar nucleus in the embryo sac to form a fertilized egg and fertilized polar nucleus, thus completing double fertilization.

There are as many ovules as you need to participate in fertilization.
