Stomata are called the "necessary evil" because while they are essential for gas exchange in plants, allowing for the intake of carbon dioxide and release of oxygen during photosynthesis, they also lead to water loss through transpiration. This water loss can be detrimental to the plant, especially in dry conditions, as it can lead to wilting and decreased photosynthetic efficiency. Therefore, while stomata are crucial for plant survival, they also present a challenge in terms of water conservation.

What is the small opening under a leaf called?
Stomata
How do plants acquire the carbon dioxide necessary for photosynthesis?
Plants acquire carbon dioxide necessary for photosynthesis through tiny openings on their leaves called stomata. These stomata allow carbon dioxide to enter the plant and be used in the process of photosynthesis.
What tiny openings on plants leaves are called?
Tiny openings on plant leaves are called stomata. Stomata are responsible for gas exchange, allowing plants to take in carbon dioxide for photosynthesis and release oxygen and water vapor.
What are the pores on leaves called?
These are known as stomata - pronounced stoh-muh-tuh ; the singular form is stoma.The are generally found on the underside of the leaves and sometimes along the stems; theyallow for gaseous exchange between the leaf and the atmosphere. Carbon dioxide in and water vapour and oxygen out (transpiration).They are normally on the underside of leaves as the waxy cuticle covers the upper epidermis; strangely some plants that are grown in tissue culture have stomata on both leaf surfaces, as a cuticle does not develop until the tissue culture plantlets are exposed to an open environment (and ultraviolet light).Plants growing in arid areas have fewer stomata to reduce transpiration where as plants in tropical areas have large or many stomata to take advanatge of the ideal growing conditions.
What are the tiny holes in plant's leaves called?
Stoma (plural stomata), they are the pores used for gas exchange.
Why is transpiration called a necessary evil?
Water transpiration means water movement through a plant. As the plant opens stomata to release carbon dioxide, some water escapes too. This cools the plants and causes moisture in the atmosphere.

Stomata
How do plants acquire the carbon dioxide necessary for photosynthesis?
Plants acquire carbon dioxide necessary for photosynthesis through tiny openings on their leaves called stomata. These stomata allow carbon dioxide to enter the plant and be used in the process of photosynthesis.

What are small openings on the underside of a leaf called?
They are called stomata, openings or pores in the epidermis of leaves.
What are small pores on the leaf surface called?
Small pores on the leaf surface are called stomata. They are responsible for regulating the exchange of gases, such as carbon dioxide and oxygen, during photosynthesis.
What tiny openings on plants leaves are called?
Tiny openings on plant leaves are called stomata. Stomata are responsible for gas exchange, allowing plants to take in carbon dioxide for photosynthesis and release oxygen and water vapor.
What are the pores in the epidermis called?
It is called the stomata.
What is bad about the stomata in plants?
Although not necessary, the stomata during gaseous exchange also favour transpiration and provide passage to the microorganisms.
What do the stomata do for the leaf?
it gives the leaf food, carbon dioxide enters through tiny holes called stomata, Oxygen leaves plant through stomata. This is called respiration
