Jewelweed, a flowering plant, has seed pods that burst open when touched and forcefully eject their seeds. these structures are favorable because they a. can cause genetic changes to occur. b. prevent germination within the seed pod. c. aid in the dispersal of the species. d. attract insects that aid in pollination.
d. aid in the dispersal of species
to aid the dispersal of the species.
Because it allows seed dispersal.
Seed dispersal is an extremely important phenomenon. Seeds are organs of perpetuation and, when ripe, need to be released from the mother plant. When they fall close and germinate, they can suffer from the accumulation of many close individuals, which leads to competition. Therefore, it is essential that seeds and fruits are taken to more distant areas. For this, they have some dispersing agents, these agents can be wind, rain, animals and even humans.
When a plant with flowers and pods that open when touched and forcefully eject its seeds, seed dispersal can occur.
The correct answer is - it help in dispersal of seed and spread the seed.
Jewelweed is a very common flowering plant found in moist and shady habitats. It is a plant that widespread and disturbs habitats by it colonizes. It is an antipruritic property.
jewelweed plants have seed pods that burst open by touching it and disperse the seed up to 4 feet, due to this property this plant is also known as touch me not plants. These seedpods are helpful in seed dispersal far from the plant and help in spreading seed and species.
Thus, the correct answer is - it help in dispersal of seed and spread the seed.
