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.

How does the shape of a leaf help it use sunlight efficiently?
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.
How does the shape of a leaf help it to use sunlight more efficiently?
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.
What do leaf cells use choropyll to absorb?
Sunlight.
What is the substance that enables a leaf to use sunlight to produce food?
The substance that enable a leaf to use sunlight to produce food is called chlorophyll. Chlorophyll is found in chloroplasts.
What is the role of chloroplasts in a leaf?
To use use sunlight to make food, and chloroplast is what makes leaves green.
What are the steps in photosynthesis?
Sunlight strikes the leaf. Chlorophyll captures light energy. Plants use energy in sunlight to make food.
How does a leaf help a plant grow?
A leaf can help a plant grow because a leaf has something called photosynthesis. Photosynthesis is the process in which plants use sunlight to synthesize foods from carbon dioxide and water. So pretty much a leaf is one way a plant can grow, live, and depend on. Of course it needs more than one to live.

How the sun help us to make calcium in your body?
Sunlight does not help us to make calcium, but it does help us to make vitamin D, which we need to use the calcium that we have; the two work together. When sunlight shines on our skin, we can use that energy to drive a photosynthetic reaction, which is not unlike the way green plants use sunlight to manufacture sugar.
What is sunlight used for?
we use sunlight to help our crops grow. Sunlight is also important to our clothes because it helps our clothes dry and gave it vitamin D. sunlight kills germs from our clothes.

what two substances enter and leave the leaf in photosynthesis?
The leaf first takes in Carbon Dioxide, or CO2, into it's self through the bottom of the leaf. It uses the CO2 and makes sugars out of it, water, and sunlight. This reaction makes a byproduct, Oxygen, that the leaf lets out, which we use to breathe.
Does plants use chlorophyll to trap sunlight?
Plants use sunlight to make food with the help of chlorophyll. The green pigment is used in this process and the process is called photosynthesis.
Does the leave use the sunlight to make food for the plant?
Yes, the leaf is the part of the plant that carries out photosynthesis. Photosynthesis is the process in which a plant uses sunlight, water and Carbon Dioxide to make food for itself.
What is the use of a leaf?
It is part of a plants' photosynthesis. Leaves draw in sunlight for a plant, then turn it into 'food'. Many animals also eat leaves.

Why are there more stomata on the bottom of the leaf?
Because the stomata are what the leaves use to breathe. They are located on the bottom of the leaf so that the plant won't lose all of its moisture through evaporation by the sunlight. The sun will not absorb the stomata.
Where does photosynthesis happen in a cell?
Photosynthesis takes place in a chloroplast of a leaf cell. They take in sunlight for use in conjunction with water and CO2 to make glucose.
What parts of the plant are responsible for nutrition?
Chloroplasts within the leaf cells. They perform photosynthesis and use Carbon, Water, And sunlight to produce energy for the plant.
