Plants have larger leaves to have a larger surface area because they grow faster.

Detailed explanation-1: -Answer. Answer: The large leaves of the shade shoot provide a larger area for trapping light energy for photosynthesis in a place where light levels are low. Plants subjected to low light intensity often grow rapidly producing long internodes (the part of the stem between each leaf).
Detailed explanation-2: -Leaf expansion is a process by which plants make efficient use of the space around them by causing their leaves to enlarge, or wither.
Detailed explanation-3: -Answer. Yes, The leaves of many plants grow in many patterns to trap maximum amount of sunlight because they need to prepare for the photosynthesis and that is why they are growing out in different patterns. The best example is Banana Leaf which gets flattened and dorsal to trap the huge amount of sunlight.
Detailed explanation-4: -In deep shade, light is more likely to be the limiting factor than carbon dioxide. So shade plants tend to have chloroplasts packed with thylakoids to make maximum use of the limited available light. They have more photosystems to funnel electrons into the same number of electron transport complexes.
