What structural or physiological adaptations enable plants to control water loss How might these adaptations affect transpiration?
Root size or structure Affects rate of water absorption, amount of water lost. Root hairs Increased number increases transpiration. Leaf hairs Presence decreases transpiration. Stomatal crypts or recessed pits Presence decreases transpiration.
Which of the following is an adaptation to reduce water loss?
They have a number of adaptations to reduce transpiration for water conservation, for example, the stem is covered by thick cuticle and has high succulency while leaves are modified into spines to reduce the loss of water by transpiration. Hence option A is correct.
How do plants protect themselves from water loss?
However, plants also lose water during this opening through a separate process called transpiration. During drought, plants protect themselves from excessive water loss by closely regulating stomatal opening and closing. Each stomatal pore is flanked by a pair of kidney-shaped guard cells.
How do plants control the loss of water?
Water loss through transpiration can be reduced by closing the stomata in the leaves using a substance called ABA. When the stomata is closed photosynthesis will decrease because no CO2 can enter through the closed stomata.
How does the plant control water loss?
Water loss through transpiration can be reduced by closing the stomata in the leaves using a substance called ABA. When the stomata is closed photosynthesis will decrease because no CO2 can enter through the closed stomata.
Which adaptations help plants store water?
Aloes are succulent plants, which have adaptation that allow them to store water in their enlarged fleshy leaves, stem, or roots. This allows them to survive in arid environments.
What adaptation helps leaves conserve water?
Thick, waxy cuticle – having leaves covered by a thickened cuticle prevents water loss from the leaf surface.
What are 3 adaptations that allowed plants to prevent water loss?
Here are four important adaptations:
- The Cuticle. The cuticle is a layer of epidermis cells in vascular plants. …
- Leaf Hairs. …
- Stomata. …
- Partnerships with microorganisms.
- Plants form symbiotic relationships with soil microorganisms like endo and ecto mycorrhizae fungi.

What adaptations would help Minimise water loss from the leaves?
Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss. Some dry-land plants have stomata only on the bottom epidermis, which further reducing water loss, and some have several layers of epidermal cells.
How is water loss control in plants?
The main ways vascular plants limit water loss include the cuticle, leaf hairs, stomata and mutualistic relationship between microorganisms. The cuticle is waxy and water repellent which keeps the water “locked” in the plant. Stomata opens and closes when the guard cells increase/decrease in size.
Which of the following structures helps in preventing water loss due to transpiration in plants?
Stomata are small pores found in the leaves of the plant that helps in the gaseous exchange during photosynthesis and respiration. Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.
Which of the following helps prevent water loss in plants?
Plants reduce water loss by closing their stomata, developing thick cuticles, or by possessing leaf hairs to increase the boundary layer. Stomata are quick to respond to environmental cues to protect the plant from losing too much water, but still allowing in enough carbon dioxide to drive photosynthesis.
