Dehiscence is through a pore or partial slit and pollen is carried by
wind
(wind pollination). Later the empty anthers dry and fall off. Usually, the style also elongates exerting the feathery receptive stigma to catch the wind borne pollen. After pollination, the spikelets close.
What foods dont need pollination?
Radishes
(Raphanus sativus), beets (Beta vulgaris), carrots (Daucus carota), onions (Allium cepa), lettuce (Latuca sativa), members of the cabbage family (Brassica spp.) and many herbs will grow and produce food in the garden without any need for pollination by bees or other methods.

Is sugar beet pollinated by bees?
Poole (1937) stated that the beet is an example of a
wind-pollinated species

Can man survive without bees?

What would we not have without bees?
We may lose all the plants that bees pollinate, all of the animals that eat those plants and so on up the food chain. Which means a world without bees could struggle to sustain the global human population of 7 billion. Our supermarkets would have half the
amount of fruit and vegetables
.
What plants are not pollinated by bees?
Radishes
(Raphanus sativus
Do bees pollinate pineapples?

are self-pollinating, and can fertilize themselves without any bees involved. … If you plant all Royal Delicious apples, for example, you won’t get fruit, with or without bees.
What would life be like without bees?
