Q.

Which plants are bryophytes?

Q. Bryophytes are dependent on water because

1. Archegonium has to remain filled with water for fertilisation.
2. Water is essential for fertilisation for homosporous nature.
3. Water is essential for their vegetative propagation.
4. The sperms can easily reach up to egg in the archegonium.

Q. Autoradiography technique was used to

1. trace the path of carbon in photosynthesis
2. establish that the oxygen evolved during phtosynthesis is by photolysis of water molecule.
3. study photorespiration in certain plants.
4. find out the absorption maximum of chlorophyll pigments.

2. Gymnosperms
3. Angiosperms
4. Bryophytes

Q.

In which plant, the gametophytic phase is main and the sporophytic phase is subsidiary?

1. Bryophytes
