In desert plants, which part of the plant primarily carries out photosynthesis, and why?
  • a)
    Scale- or spine-like leaves, to reduce loss of water by transpiration.
  • b)
    Green stems, as they can carry out photosynthesis.
  • c)
    Roots, to absorb more water.
  • d)
    Flowers, to attract pollinators.
Correct answer is option 'B'. Can you explain this answer?

In desert plants, the leaves are often modified into scales or spines. This modification helps reduce water loss by minimizing the surface area from which transpiration (the process of water evaporation from plant surfaces) can occur. Since these modified leaves (scales or spines) cannot perform photosynthesis efficiently, desert plants adapt by having green stems. These green stems contain chlorophyll, which allows them to carry out photosynthesis. This adaptation is crucial for desert plants as it enables them to synthesize food while minimizing water loss, ensuring their survival in harsh, arid environments.

Correct answer is option B.
Because green stems contain chlorophyll. And photosynthesis is occured in plants with chlorophyll.
We can relate this with the green leaves. It is the same process in the green stems too but they are stems and those are leaves. But both have Chlorophyll.

Green Stems: The Primary Site of Photosynthesis in Desert Plants
Desert plants have evolved unique adaptations to survive in arid environments where water is scarce. One of these adaptations involves the location of photosynthesis within the plant. In desert plants, the primary site of photosynthesis is the green stems.

Reducing Water Loss
The scale- or spine-like leaves of desert plants have reduced surface area to minimize water loss through transpiration. This helps the plant conserve water in the arid desert environment. By carrying out photosynthesis in the green stems instead of the leaves, desert plants can reduce the risk of losing precious water through evaporation.

Efficient Use of Resources
Green stems in desert plants are capable of carrying out photosynthesis, utilizing sunlight to produce energy for the plant. This adaptation allows the plant to efficiently use available resources, such as sunlight and water, to sustain its growth and survival in harsh desert conditions.

Adaptation to Harsh Environments
By locating the primary site of photosynthesis in the green stems, desert plants have adapted to their arid surroundings. This unique strategy enables them to thrive in environments where water is limited and temperatures are high. The green stems of desert plants serve as an essential organ for photosynthesis, helping the plant to produce energy and survive in challenging desert conditions.
