Question

What are three requirements associated with leaves as photosynthetic organs?

A. Thinness, red color, and waxiness.
B. Broad surface area, chlorophyll, and vascular tissues.
C. High water content, narrow shape, and spines.
D. Hard texture, small size, and shade tolerance.

Answer 1

Leaves, as photosynthetic organs, have three important requirements: broad surface area, chlorophyll, and vascular tissues.

Step-by-step explanation:

Leaves are the main site of photosynthesis in plants. Three important requirements associated with leaves as photosynthetic organs are:

1. Broad surface area: Leaves have a large surface area to maximize the absorption of sunlight for photosynthesis.
2. Chlorophyll: Leaves contain chlorophyll, a pigment that captures light energy and is essential for photosynthesis.
3. Vascular tissues: Leaves have vascular tissues, such as xylem and phloem, which transport water, nutrients, and sugars within the leaf and between the leaf and the rest of the plant.
