_____ is provided for a plant by its leaves.

• A. Water storage
• B. A food factory
• C. Pollination site
• D. Root support

Answer: (B)

Leaves provide the plant with food by acting as its food factory through photosynthesis. They capture light energy with chlorophyll in the chloroplasts and use it to convert carbon dioxide and water into sugars such as glucose. These sugars serve as the plant’s energy source and building blocks for growth, and they’re transported to other tissues via the phloem to fuel roots, stems, flowers, and storage tissues.

Other options don’t fit as the main role of leaves: water storage happens in specialized tissues of some leaves or stems, but not as their primary function; pollination occurs in flowers; root support comes from the roots and supporting tissues in stems.
