The process which cannot happen in plants without sunlight is: **a. photosynthesis** Here's why: * **Photosynthesis** is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. Sunlight provides the energy needed for this process. * **Respiration** occurs in plants (and all living organisms) continuously, day and night, to release energy from stored food. It does not directly require sunlight. * **Digestion** in plants refers to the breakdown of complex substances into simpler ones, often for transport or utilization. This process doesn't directly depend on sunlight. * **Assimilation** is the process by which plants incorporate absorbed nutrients into their own structure. This also doesn't directly require sunlight.
