Answer #1

1) The picture represents a moss plant (bryophyte)

It requires water/moisture for reproduction.

Moisture is required for the liberation of male gametes (antherozoids) from the antheridia and then dispersal of antherozoids which swim in water to reach the female sex organ (archegonia). The opening of the archegonial neck also requires moisture which then facilitates the entry of antherozoids into the archegonia for fertilization.

2) The organism belongs to dinoflagelllate group of photosynthetic protists.

The organsims moves with the help of two flagella attached to its body.

The organism is an autotroph (photosynthetic)

Thank you
