Stomata are present in leaves where CO2 is required for photosythesis and lenticels are pesent on woody parts of the plant to provide perforation. SINCE THE REQUIREMENT OF CO2 is more in the leafy areas, there are many stomata than the lenticels.

What is a plants most valuable resource?
stomata
What is the primary gas exchange organ for most plants?
Stomata
In most plants stomata on a leaf must be during the calvin benson cycle?
In most plants stomata is usually opened on leaves to preserve water. As a result, CO2 is added during the Calvin Benson Cycle.
Is it true that stomata and mitochondria are two speacialized cells found only in plants?
Stomata are a structure found in leaves; only plants have leaves, so only plants have stomata. Mitochondria, however, are organelles found in the cells of all kinds of organisms, not just plants.
How do gases enter and leave plants?
In terrestrial plants, gas enters and leaves (termed "gas exchange") through cell-lined pores called "stomata." Stomata open and close in response to light and humidity, permitting oxygen, carbon dioxide and water vapor to enter and leave the plant. In most terrestrial plants, the stomata are located on the surface of the leaves, or in cacti, on the surface of the stems. In aquatic plants, gas exchange directly though the tissue surface.

Is the loss of water from plants?
Plants lose most of their water by transpiration through the stomata of the leaves.

Where are stomata generally most abundant in the majority of leaves?
On a dorsi-ventral leaf most of the stomata are found on the lower side of the leaf, that remains away from sunlight. On an iso-bilateral leaf stomata are present on both the sides, upper as well as lower.
How many stomata are likely to open at night?
In most green plants the stomata are only open during the day. They allow carbon dioxide to reach the cells where the majority of photosynthesis takes place. As they also allow transpiration (water loss) the stomata of most plants close during the night when photosynthesis is not possible. There is a group of mainly desert plants known as CAM plants. These carry out a process called Crassulacean acid metabolism, which effectively allows them to store carbon dioxide in their leaves. In these plants the stomata are normally closed during the day to prevent water loss when temperatures are high, and open during the night when temperatures are lower.
Why does duckweed have stomata on the top surface of the leaf?
duckweeds does not have stem but only roots.
