Question

A big advantage with the evolution of pollination was:

1. Asexual reproduction could happen
2. Sexual reproduction could happen in dry environment
3. Sexual reproduction could happen underwater
4. Sexual reproduction could happen in environments water

2. If you compared plant reproduction to that of animals, the cells in pollination would be equivalents to:

1. The ovary
2. Sperm
3. An unfertilized egg
4. A zygote

3. The group of Gymnosperms includes:

1. Brown Algae
2. Ferns
3. Flowering Plants
4. Evergreens and Conifers

4. The Angiosperms include:

1. Ferns
2. Christmas Tree
3. Some Unicellular Organisms
4. Plants with fruit

5. The biggest difference between Angiosperms and Gymnosperms:

1. Whether they have leaves or not
2. Whether they have flowers or not
3. Whether they have seeds or not
4. Whether they have circulatory structures or not

Answer 1

1) pollen grain is a trait found in gymnosperms and angiosperms, the pollen grains can be carried by the wind, animals, etc to the female reproductive structures, so the fertilization does not require water, but in lower plants like bryophytes, pteridophytes the water is required for the fertilization.

so the answer is b) Sexual reproduction could happen in dry environment.

2) If you compared plant reproduction to that of animals, pollen grains are equivalent to the sperm, egg cell in the female plants is equivalent to egg cell in the females.

so the answer is b) sperm.

3) Gymnosperms are vascular plants having seeds.

ferns are pteridophytes, brown algae is a type of algae, flowering plants are angiosperms,  Evergreens and Conifers are gymnosperms.

so the answer is d) Evergreens and Conifers

4) ferns are pteridophytes

Christmas Tree is a gymnosperm

Some Unicellular Organisms- unicellular organisms can be either bacterias or protists.

Plants with fruit- are angiosperms, angiosperms have flowers, the ovary in the flower develops to fruit, so the answer is d) Plants with fruit

5) gymnosperms and angiosperms are vascular plants, gymnosperms have seeds, but the seeds are exposed, the angiosperms have flowers so the seeds are covered in the fruit. so the answer is b) hether they have flowers or not
