In particular environments, such as deserts, some plants have adapted to reduce water loss due to high temperatures and limited water availability. These adaptations include having scale- or spine-like leaves, which significantly reduce the surface area through which water can be lost by transpiration. However, these plants still require photosynthesis to produce food. Given these adaptations, what part of these desert plants primarily carries out photosynthesis in the absence of substantial leafy green surfaces?
1
The plants rely solely on their roots for photosynthesis.
2
The flowers of these plants are adapted to perform photosynthesis.
3
The green stems and branches of these plants take over the role of photosynthesis.
4
These plants do not perform photosynthesis and survive by absorbing nutrients directly from the soil.
