Why is stomata called the necessary evil?

Answer 1

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.

Answer 2

Oh, dude, stomata are like the bouncers of the plant world. They let in carbon dioxide for photosynthesis, but at the same time, they can lose water through transpiration. So, they're kind of a necessary evil because plants need them to breathe, but they can also be a bit of a hassle with all that water loss. It's like they're the plant's way of saying, "You can come in, but don't make a mess."

Answer 3

Well, friend, stomata are like tiny windows on a plant's leaves that let them breathe in carbon dioxide for photosynthesis. They also release oxygen, which is wonderful for us. However, sometimes stomata can lose too much water through them, which can be a challenge for the plant. So, they're called a "necessary evil" because while they're essential for a plant's survival, they can also cause water loss.

Answer 4

Large amount of water are transpired to the atmosphere making the situation for fresh water worse.But it is necessary for the health development of the plant .It causes the sap to move and causes cooling in plant.So transpiration is necessary evil.

Answer 5

At any one time, the stomata may prevent water vapor from escaping the cell by remaining closed, or allow carbon dioxide to enter the cell by opening. Both are H2O and CO2 are vital for photosynthesis, but the stomata controls their presence in the cell.

Answer 6

Stomata are important for gas exchange in plants but can also lead to water loss through transpiration. This is why they are sometimes referred to as a "necessary evil" - essential for photosynthesis and respiration, but also potentially contributing to dehydration in plants.
