What is the cuticle in a leaf?
The cuticle is a waxy covering on the leaves of plants. It is produced by the upper epidermis, which is like the skin of a leaf. Its function is to protect the leaf from water loss through evaporation. Hope this helps!
Do plants release more water through their leaves or stem?
Plants release more water through their leaves due to a process called transpiration, where water evaporates from leaf surfaces. Stems also play a role in water transport, but the majority of water loss occurs through the leaves.
Why do most water loss occur from the lower surface of the leaf?
Most water loss occurs from the lower surface of the leaf because it has more stomata, which are tiny pores that allow water vapor to escape during transpiration. The lower surface is also less exposed to direct sunlight, reducing the risk of excessive water loss through evaporation.
What controls water loss in a leaf?
Water loss in a leaf is controlled by the stomata, which are tiny openings on the leaf surface. When the stomata are open, water vapor can escape through transpiration. The guard cells surrounding the stomata regulate the opening and closing of the stomata to help prevent excessive water loss.
What is the protective substance that restricts water loss from a leaf?
The protective substance that restricts water loss from a leaf is called cuticle. It is a waxy layer on the outer surface of the leaf that helps to reduce water evaporation and protect the leaf from drying out.

What do you call a process where the loss of water through the stomata of a leaf takes place?
Transpiration.
What part of the leaf collects water?
The part of the leaf that primarily collects water is the cuticle, a waxy layer that covers the leaf's surface. While the cuticle itself doesn't absorb water, it helps minimize water loss through evaporation, allowing the leaf to retain moisture. Additionally, the leaf's stomata, small openings on the surface, play a crucial role in regulating water loss and gas exchange. Overall, the leaf's structure is designed to efficiently manage water for photosynthesis and other functions.
How does the water changed between its entry and its exit of a leaf?
When water enters a leaf through the roots, it is primarily in the form of liquid and contains dissolved nutrients. As it moves through the leaf, it undergoes a process called transpiration, where water evaporates from the leaf's surface, mainly through small openings called stomata. This loss of water not only helps in cooling the leaf but also facilitates the uptake of more nutrients. By the time water exits the leaf, it is typically in vapor form, having lost some of its dissolved nutrients during the process.
Why is the top of a leaf waxy?
Leaves have a waxy coating called a cuticle to prevent excess water loss through transpiration. Without this coating they would dry up. The waxy layer blocks the stomata preventing as much water evaporating from them
Why do dead leaves gradually shrink if left in a warm and damp place?
The main reason is the dehydration or loss of water.
Which process makes the water potential in a leaf more negative?
A.The pressure placed on the leaf by the cuticleB.The evaporation of water from mesophyll cellsC.The movement of water into the leaf by root pressureD.The increased K+ pumped out of guard cellsE.The movement of water from the veins into the leaf

What is the function of a stoma on a leaf?
A stoma on a leaf allows for the exchange of gases, such as oxygen and carbon dioxide, during photosynthesis and respiration. It also helps regulate water loss through transpiration.
