The leaf's underneath surface is covered with millions of stomata, for rapid gas exchange. Rapid gas exchange, more carbon dioxide absorbed, more photosynthesis.

∙ 15y agoThin leaves are not required to support photosynthesis. What is important is that the chlorophyll and other photosynthetic apparatus be close to the surface of the plant.
The primary reason for plants having many thin leaves is rapid growth rate. Thin leaves, being lightweight, allow branches and branchlets to support many leaves, and thus a lot of leaf surface to absorb sunlight and power photosynthesis.
In addition to sunlight, nutrients and sufficient water are required for rapid growth. There are many plants with thick leaves, such as cacti and numerous other plants, that evolved in arid regions with plenty of sunlight, but few nutrients. These are most slow-growing, due to the lack of moisture and nutrients, except for some annuals that grow rapidly during short wet periods, then go dormant.
It would do cacti no good to collect greater quantities of solar energy, because the other components of growth are available only in reduced quantities. In those plants, the ability of their thick,waxy leaves and trunks to collect and store water is more important than a lot of leaf surface.

Why are leaves blades thin and flat?
Leaves are usually broad, thin, and flat to increase surface area for photosynthesis. The wider the leaf is, the more spots there are for photosynthesis to take place.
Underwater plants have long and thick leaves if they had big broad leaves?
Normally this would have to do with the origin and location of the plant. Long, thin leaves offer less resistance to water flow; these types of plants are normally found in fast, running water. Note: Not all underwater plants have narrow, thin leaves!
Why the water lily has broad leaves and a hollow flexible stem?
Lotus is an aquatic plant fixed at the bottom of the pond. To reach the surface of the water lotus stems are thin & hollow.
In which part of the plant does most of the photosynthesis take place?
Any part of a plant that is green can perform photosynthesis, its just that leaves have special adaptations to optimize its efficiency.So plants with green stems can, plants with brown woody stems can't.
Why are most leaves thin and spongy inside?
Cuz they are, ok
Why do leaves have a large surface area?
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
How might the rate of photosynthesis be affected by increasing its thickness?
The rate of photosynthesis would be slowed down by increasing the thickness of a leaf. Leaves that are broad and thin offer the best conditions for the process.
Why are leaves blades thin and flat?
Leaves are usually broad, thin, and flat to increase surface area for photosynthesis. The wider the leaf is, the more spots there are for photosynthesis to take place.

What is the thin part of the leaf called?
The Blade, or lamina, is the broad, flat part of the leaf. Photosynthesis occurs in the blade, which has many green food-making cells.
What is a 5 letter word for wide not thin?
broad,
What would help a plant survive in limited sunlight?
its one of these to sum it up colorful leaves large leaves deep roots thin cuticle
What is the disadvantage to the leaf of being thin and broad?
The flatter and broader the leaf , the more of a surface area it has. the more surface area it has the more space it has for photosynthesis to take place therefor it can gain more nutrients.
How the leaf adapted to perform phtotsynthesis?
Leaves have large surface areas to absorb as much light as possible, and are thin for rapid diffusion; also, they contain chlorophyll, essential for photosynthesis.
Why do submerged plants have narrow thin leaves?
Narrow, thin leaves have lower pressure under water.
How do water and nutrients move through a non-vascular plant?
They transport material, such as nutrients, through rhizoids, long thin cells that also anchor and absorb the minerals. They transfer material from rhizoid to rhizoid through the process of osmosis.
What are words that are not broad?
Words that mean "not broad" may be "skinny" or "thin". To describe an area, you could use the word "narrow". Example sentences Although the football player's shoulders were quite broad, his hips were very narrow. The thin model thought her hips were too broad.
