Dinoflagellate -
Dinoflagellate is a unicellular algae. It contains two flagella. These two flagella are different in appearance and size. These two flagella arise from the ventral side of the body.
Dinoflagellate possess ribbon like transverse flagella. Out of two flagella, one flagella beats posteriorly and other flagella beats in the left side of the body.
Ques 1. What part of the dinoflagellate (the algae) is actually damaged by excess energy?
Answer:
Energy first falls on the Photosystem II of the plant. When excess of energy falls on the leaf of the plant then the high temperature can cause irreversible damage to the photosystem II reaction center protein D1.
Due to excess of energy on the photosystem II can cause various changes. These are:
- Excess energy disrupt the stability of the thylakoid membrane.
- It alters the redox state of electron transport chain
- It damages the Photosystem II.
