44. A mutation causes a particular plant to produce small fruit with almost none of the usual pulpy flesh. What outcome do you expect for this plant’s progeny?
The seeds will have poor germination.
The seeds will germinate, but will quickly run out of energy stores.
The seeds will not be dispersed.
The seeds will dry out.
30. Naked seeds, pollination by wind, paraphyletic
In gymnosperms, seeds are not enclosed in fruits. So they are also called as naked seeds.
The pollen grains of gymnosperms are light and non sticky and are produced in numerous amount because they are pollinated by wind.
Gymnosperms are paraphyletic meaning they form a group which includes an ancestor but not all of its descendants. This is because all the gymnosperms do not share naked seeds. Some of gymnosperms have seeds covered by sporophytic tissue.
41. Extinction of animals, balancing ecosystems, increased erosion, reduction in potential medicines, reduced food supply
Not only angiosperms, but the loss of any type of plant will result in the listed problems. But the climate will not get moderated. In fact it will become worse.
42. The seeds will germinate, but will quickly run out of energy stores
The flesh In The Seed is meant for the nutrition of the seed. So if the amount of flesh is less, than the seed will run out of the energy stores quickly.
Please give a good rating.
