Question

Choose the false statement:

A) Among angiosperms, fertilization is the term used to describe the process when pollen grains are released into the wind, eventually by chance on the stigma of a flower.

B) In flowering plants pollination most often relies on insects or other animal vectors.

C) Germination is a process that involves the emergence of a plant embryo from the seed coat.

Choose the false statement:

A) Evolutionarily, conifers can attribute their success in colonizing the land and displacing lower plant species by relying on a mutualistic coevolution with certain groups of animals.

B) The nutrient tissue found in the seeds of gymnosperms (conifers) is not quite as nutrient rich as that found in the seeds of angiosperms (flowering plants).

C) Anthers are the male parts of flowers where pollen grains are formed.

Choose the false statement:

A) One of the similarities seen between ferns and mosses is that they both require water to reproduce since they both produce flagellated gametes.

B) Conifers (Gymnosperms) are more primitive than flowering plants (Angiosperms); this is evident since the mechanisms for pollination and species dispersal of conifers are so much less efficient.

C) The purpose of seeds formed by conifers is species dispersal; seeds provide animals with a tasty, nut-like, reward that encourages them to transport the plant embryos to distant sites.

Answer 1

1.Among angiosperms, pollination is the term used to describe the process when pollen grains are released into the wind, eventually by chance landing on the stigma of a flower.Fertilisation is the fusion of the male and female gametes.

In flowering plants pollination takes place wit the help of insects like bees, butterflies, wasps, etc...some plants have even developed special relations with the insects and other animal vectors like bats to achieve pollination and more chances of survival. Thus, In flowering plants pollination most often relies on insects or other animal vectors.

Germination is a process that involves the emergence of a plant embryo from the seed coat.

Thus, the false statement among these is:

A) Among angiosperms, fertilization is the term used to describe the process when pollen grains are released into the wind, eventually by chance on the stigma of a flower.

2.Evolutionarily, conifers cannot attribute much but instead angiosperms can attribute their success in colonizing the land and displacing lower plant species by relying on a mutualistic coevolution with certain groups of animals.

The nutrient tissue found in the seeds of gymnosperms (conifers) is not quite as nutrient rich as that found in the seeds of angiosperms (flowering plants).

Anthers are the male parts of flowers where pollen grains are formed.

Thus, the false statement among the above statements are:

A) Evolutionarily, conifers can attribute their success in colonizing the land and displacing lower plant species by relying on a mutualistic coevolution with certain groups of animals.

3.Ferns and Mosses are both gymnosperms. One of the similarities seen between ferns and mosses is that they both require water to reproduce since they both produce flagellated gametes.

Conifers (Gymnosperms) are more primitive than flowering plants (Angiosperms); this is evident since the mechanisms for pollination and species dispersal of conifers are so much less efficient.

The pollination of conifers usually occur through means of wind and the seeds are then dispersed either by being dropped, eaten or carried away by forest wildlife.But the purpose of seeds formed by conifers is not species dispersal; seeds don't always provide animals with a tasty, nut-like, reward that encourages them to transport the plant embryos to distant sites.

Thus, the false statement among the above statements are:

C) The purpose of seeds formed by conifers is species dispersal; seeds provide animals with a tasty, nut-like, reward that encourages them to transport the plant embryos to distant sites.
