### Step-by-Step Text Solution 1. **Definition of Source and Sink:** - In plants, the terms "source" and "sink" refer to the parts of the plant involved in the transport of nutrients, particularly sucrose, through the phloem. - **Source:** This is the organ where food (primarily sucrose) is synthesized. The main source in plants is the leaves, where photosynthesis occurs. - **Sink:** This is the part of the plant that requires or stores the food. Sinks are typically non-photosynthetic parts, such as roots, fruits, and developing buds. 2. **Function of Source and Sink:** ...

In what kind of plants do you come across 'Kranz' anatomy? To which conditions are those plants better adapted? How are these plants better adapted than the plants which lack this anatomy.

The efficiency of carnot's heat engine is 0.5 when the temperature of the source is T_(1) and that of sink is T_(2) .The efficiency of another crot's heat engine is also 0.5.the temperature of source and sink of the second engine are respecitvely

The efficiency of a carnot engine is (1)/(6) . If the temperature of the sink is reduced by 62 K, the efficiency becomes (1)/(3) . The temperature of the source and the sink in the first case are respectively.

What is the source of carbon hydrogen and oxygen in plants?

The efficiency of a Carnot cycle is 1//6 . If on reducing the temperature of the sink by 65^@C , the efficiency becomes 1//3 , find the source and sink temperatures between which the cycle is working.
