Question

why might there be more plasmodesmata connecting adjacent cells in plant tissues such as seeds and fruits?
increase the transport of materials that are important for development and growth
increase the rate of photosynthesis by capturing more light energy
decrease the volume of the central vacuole so that cells stay small and have a larger surface area
decrease the movement of water out of cells to prevent plasmolysis

Explanation:

Plasmodesmata are channels for inter - cellular transport. In seeds and fruits, there is a high demand for the transport of nutrients and signaling molecules for development and growth. So, more plasmodesmata would facilitate this transport. Photosynthesis is mainly in leaves, not seeds/fruits. The volume of the central vacuole and water movement to prevent plasmolysis are not related to the function of plasmodesmata in this context.

Answer:

Increase the transport of materials that are important for development and growth
