Final answer:
Ground tissue in leaves mainly facilitates photosynthesis, supports structure, and stores and transports water and sugars.
Step-by-step explanation:
A property of ground tissue inside leaves is that it is primarily responsible for photosynthesis. This tissue is predominantly made up of parenchyma cells, which contain chloroplasts that capture light energy and convert it into chemical energy through the process of photosynthesis.
Besides this vital role, ground tissue also plays a part in supporting the structure of the plant, storing nutrients such as water and sugars, and assisting in the transport of these substances to other parts of the plant.
