Lactose metabolism is regulated by lac operon in prokaryotic cells. When in the environment lactose is present, the cell signals the presence of lactose and synthesizes the enzyme required for the degradation of lactose. Removal of lactose from the environment leads to the termination of the enzyme synthesis. Thus, the metabolism of lactose is environment dependent.
The metabolism of lactose is also dependent on the presence of glucose. Glucose is the favorite food for bacteria. If glucose and lactose both are present in the environment, the bacterial cells prefer glucose over lactose and lactose is not metabolized. In the absence of glucose, the cells will metabolize lactose.

Answer:
The correct answer is a. the photosynthetic part of a lichen.
Explanation:
Lichen is a symbiotic association in which the algae and fungi are associated with each other. Fungus can not make there own food so they are not photosynthetic like algae or plants and in lichens algae are the photosynthetic part while fungus plays the role of absorbing nutrients for the algal partner.
Lichens are found all over the world and they absorb industrial pollution very quickly so are also referred to as pollution indicators of the environment as they do not grow in a polluted area.
Therefore the photosynthetic part of lichen is algae, not fungus so the correct answer is a.
