A plant species lives in an area with limited sunlight. Which structure would be most helpful to the plant to help it survive?
A
colorful flowers
B
large leaves
C
deep roots
D
tiny seeds
Explanation: 

Detailed explanation-1: -Answer:Large Leaves Leave are the part of a plant that contains chloroplasts. Chloroplasts are structures that contain chlorophyll, a pigment that captures sunlight and allows the plant to make sugars. The larger the leaf surface a plant has, the more sunlight it can capture.

Detailed explanation-2: -Some plants can survive in very low-light conditions. If you think about dark, rainforest canopies, there are plants that grow in that environment. They have evolutionary adaptations to handle these low-light environments, which include making broad, thin leaves to capture as much sunlight as they can.

Detailed explanation-3: -In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

Detailed explanation-4: -Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color.

Detailed explanation-5: -In leaves, cells in the mesophyll (the tissue between the upper and lower epidermis) are uniquely suited to carry out photosynthesis on a large scale. This is due to their high concentration of chloroplasts, which are the sites of photosynthesis. More chloroplasts means more photosynthetic capability.
