Which of the following is/are the main absorbing organ/organs of plants?

In plants, the roots are the primary organs for the absorption of water and minerals from the soil, facilitated by root hairs that increase the surface area for efficient uptake. However, leaves also function as absorbing organs. While their primary role is photosynthesis and gas exchange through stomata, they are capable of 'foliar feeding,' where nutrients and water are absorbed directly through the leaf surface. This method is often used to rapidly correct nutrient deficiencies. Some research indicates that plants can absorb water through their entire surface, including stems, but roots and leaves remain the functional main absorbing organs. Bark generally serves as a protective layer and is not considered a main absorbing organ for water or nutrients in the same capacity as roots or leaves. Therefore, both roots and leaves are recognized as the main absorbing organs.
