Answers
Explanation:
1.Ferns and mushroom reproduce through
(spores/buds). Ferns, fungi and mosses reproduce by releasing millions of spores through the air. The spores are fed eggs and are spread through the environment by wind. Mosses don't have flowers or seeds, but use spores to reproduce.
2.Reproduction in Bryophyllum occurs asexually through vegetative propagation by leaves. The leaf of Bryophyllum is broad and has notches at its margins. Buds arise from the notches. ... These buds can give rise to new plants with adventitious roots, shoots and small leaves.
3.There are some natural agents that help in scattering the seeds away from the parent plant. These are wind, water, animals and by the explosion of fruits
4.Explosions
Some plants have pods that explode when ripe and shoot out the seeds. Lupins, gorse and broom scatter their seeds in this way. Pea and bean plants also keep their seeds in a pod. When the seeds are ripe and the pod has dried, the pod bursts open and the peas and beans are scattered.
5.(1) Dispersal of Seeds and Fruits by Wind
The seeds and fruits dispersed by wind either have wing-like structures or they have hair or they are very small and light, which helps them to be easily carried away by the blowing wind
