How do dandelions,Xanthium strumarium, and peas disperse their seeds
Do you know these? Introduction to the dispersion of dandelion, Xanthium strumarium, and pea seeds in the aspect of green plants and flowers, let's follow the editor to see!
Wind dispersal: After the dandelion flowers wither, white fluffy balls will grow, and the fluffy balls will be blown away by the breeze. Adhesive dispersal: Xanthium strumarium seeds are equipped with barbs that will stick to passing animals. Ballistic dispersal: When the pods of peas mature, they will burst, shooting the seeds inside (Z-D) to a distance. Artificial dispersal: People will collect seeds for sowing.
How do dandelions, Xanthium strumarium, and peas disperse their seeds
1 -- Wind Dispersal --
Dandelions rely on wind to disperse seeds. When dandelions enter the flowering period, they grow small yellow flowers similar to chrysanthemums. After the flowers wither, a white fluffy ball made up of countless tiny seeds grows at the center of the flower. When the breeze blows, the fluffy ball is blown away, and the seeds float into the sky, spreading to distant places with the wind.
2 -- Adhesive Dispersal --
Xanthium strumarium is an annual herb with a height of about 90 cm, triangular-ovate leaves with coarse锯 teeth edges, and green color. The fruit is obovate after maturity, with a dense distribution of barbs on the surface. When mammals pass by, the Xanthium strumarium seeds will hook onto the hair and spread to distant places.
3 -- Ballistic Dispersal --
Peas are annual攀援 herbaceous plants of the legume family, about 2 meters tall, entirely green, with heart-shaped leaves. The pods mature from July to September every year, are oblong in shape, about 10 cm long, and contain 2-10 seeds inside. Mature pods suddenly burst, shooting the seeds inside (Z-D) to a distance to complete the dispersal process.
4 -- Artificial Dispersal --
Dandelions, Xanthium strumarium, and peas can all be artificially dispersed. Children will blow into the dandelion fluff during play, blowing the mature seeds into the sky, while Xanthium strumarium is a common weed in rural areas, and children will pick the seeds for mischief. Peas are common crops, and farmers will pick the mature pods and store them for sowing the following year.
