Which plants spread their seeds by means of the sun?

The seeds of many plants need external forces to spread. For example, persimmons and Achyranthes bidentata spread by animals, while dandelions and willows spread by wind.So which plants spread their seeds by means of the sun?

1. Which plants spread their seeds by means of the sun?

Impatiens, peas, sesame, rapeseed, mustard, peas and soybeans, mung beans, wood sorrel and other plants all spread their seeds by means of the sun. This is because after the seeds of these plants mature, the fruit walls become dry and hard, and after being baked by the sun they burst open, so the seeds can be ejected.

2. What other ways are there for plant seeds to spread?

1. Spreading by water

Coconuts spread by water. After a coconut matures, the coconut fruit falls into the sea and drifts far away with the seawater.

After the fruit of the water lily matures, it sinks to the bottom of the water. After the fruit wall rots, the seeds wrapped in a spongy outer seed coat float up and drift to other places.

2. Spreading by small birds or other animals

Cherries, wild grapes, wild ginseng and others rely on small birds or other animals to eat the seeds into their stomachs. Since they cannot be digested, they are excreted with the droppings and spread in all directions. In addition, pine nuts are carried away by squirrels when they store food for the winter.

3. Spreading by wind

The red osier willow spreads its seeds far away by the drifting of its catkins.
