Question

multiple-choice question
what are the characteristics of leaves that makes them adoptive to
photosynthesis?
veins carry other nutrients brought in from roots/soil
there are many leaves per plant
they have a waxy coating
large surface area
thin

Explanation:

• Veins carry other nutrients brought in from roots/soil: This is related to the transport of substances in the plant, not directly to photosynthesis.
• There are many leaves per plant: This is more about the plant's overall structure for photosynthesis (more leaves mean more photosynthetic sites in general), but not a characteristic of a single leaf for photosynthesis.
• They have a waxy coating: The waxy coating (cuticle) is mainly for reducing water loss, not directly for photosynthesis.
• Large surface area: A large surface area allows more light to be absorbed (light is one of the requirements for photosynthesis) and more carbon dioxide (from the air) to come into contact with the leaf cells (carbon dioxide is a reactant in photosynthesis).
• Thin: A thin leaf structure means that the distance for light to penetrate to the photosynthetic cells (e.g., mesophyll cells) is short, and also for the diffusion of gases (carbon dioxide in and oxygen out) to be more efficient.

Answer:

Large surface area, thin.
