How does the shape of a leaf help it to use sunlight?

Answer 1

As much as I know... Broader, fuller leaves will be nearer the base because they are shaded by the upper tree canopy. If they are broader, larger, or have less exaggerated lobes then they have more surface area to catch what sun-rays they can. Likewise, leaves at the top of the canpy are distictly lobed, smaller, etc, because they have a greater exposure to sunlight. They can't typically absorb as much light as they are exposed to, so they have less surface area so they don't absorb too much and litterally get burnt out. Other shape characterisitcs are typically due other environmental pressures over time.

Answer 2

The flat shape of leaves allow for maximum surface area to absorb sunlight. The leaf's thinness makes sure that the sunlight and the products of photosynthesis are available to all the cells of the leaf.

Answer 3

The surface of the plant that is facing up is "dark green". The "dark green" area is the chloroplast which contains the chlorophyll, and the chlorophyll captures the light used for photosynthesis.

Answer 4

it helps with photosynthesis because it is thin, long and broad so light energy (sun at most times) can reach all parts of the leaf and also produce food by photosynthesis.

Answer 5

Photosynthesis firstly depends on the color of leaf if the color of leaf is green then chlorophyll is present in the leaf ,as we know photosynthesis depends on chlorophyll,so color plays an important role in photosynthesis

Answer 6

well.......

big, round leaves have more surface area so they can absorb more sunlight;

cactus leaves are small and thin so not much water evaporate from them.

(in case u didnt know, cactus leaves are more commonly known as 'spikes.')

Answer 7

The shape of a leaf is very important to a plant in using sunlight efficiently. The larger the leaf is the more sunlight the plant is able to collect.
