Scientists hypothesized that more than 250 years ago, when conifers evolved, climate conditions were dry and cool. In response to these conditions, most conifer developed leaves that are long and thin. This shape reduces the surface area from which water can be lost by evaporation. Another water conserving adaptation is the thick, waxy layer that covers conifer leaves. In addition, the openings of the leaves that allow for gas exchange are located in the cavities below the surface of the leaves, also reducing water loss.

∙ 11y agoSometimes leaves will curl up, to again increase humidity against the leaf surface and try ot stop water loss via transpiration......these are really only leaves in quite sry environments.....also these leaves will tend to have a thicker cuticle and often store water in leaves or stem eg succulents or cacti depending on where you live. waxy cuticle to prevent water loss
Guard cells to close over stomata to prevent water loss
Stomata on the lower surface of most leaves to prevent less water loss by transpiration ( is lower temp, higher humidity)

∙ 11y agoThe conifer leaves are thin and have a small surface area so water can drip off after rain and also that excess water which hasn't been used for food for the plant can be taken away.

It is good for the animals in the coniferous forest, so they can hide and camouflage from predators

Succulent plants have fleshy leaves with thick surface layers These characteristics help the plant?
Fleshy leaves and thick surface layers help in keeping water inside the plant, preventing it from drying out. The cactus is an extreme example of this adaptation, made to survive in arid environments.
Why is it that plants normally shed off their leaves during dry season?
when there is drought the water is scarce. so due to that the water absorbed by the tree is less. this water is not enough for the trees. the scorching heat of the sun the tree lose their leaves because not getting water properly
What is the Characteristics of floating plants?
A plant's adaptations for floating in water are floating leaves and finely dissected leaves. These plants can only grow in water or in soil that is always saturated with water.
What plant make wax?
Plants use waxy substances on their leaves to help reduce transpiration, the evaporation of water from plants. The wax helps to keep water in the plant as to not dehydrate the plant.
How do the flowes leaves and stems help plants meet their basic needs?
The flowers are the sexual organs. A basic need is to reproduce. The leaves make the food. The stems carry the food and water to every part of the plant that needs it much like our veins and arteries.
How do plants help conserve water and soil?
when the plants wilt they bend and result in the shortening of transpiration which helps to conserve water

How does water help plants with no leaves?
water helps plants with no leaves by the roots absorbing the water then the water goes up the xylem (stem) and helps the entire plant continue to grow and produce new leaves. some plants can photosynthesizes without laves
How can Xeriscaping help conserve water?
Xeriscaping emphasizes on using native plants to beautify your space and conserve water. Native plants usually require less water to thrive on as compared to foreign plants. Which means the frequency of watering your plants goes down. In this way Xeriscaping helps conserve water while gardeining. Check out the link below for some cool tips on Xeriscaping.
Can nuclear plants help conserve energy?
They can help conserve other fuels which are used to generate energy. They can be used in place of those fuels but they, along with all power plants, generate energy they do not conserve it.
What is the evolutionary importance of pine needles?
The needles are the leaves of the tree, which allow it to carry out photosynthesis and produce food
How does the wax on leaves in desert ecosystem help plants?
Slows down evaporation of water from the pores of the leaves.
How does a leaf help plants?
It helps to balance the amount of water plants take in. If there is too much water in the plant leaves will let some water out through the tiny holes on their underside. Plants in dry places may have leaves with waxy or fuzzy coatings to help keep water in. A plants leaves may also help to protect the plant from being eaten. Leaves might be poisonous sharp or tough to chew. Hungry animals will leave the plant alone.
How do aquatic plants float on water?
Some plants, like water hyacinth, float in water. They have special types of leaves that help them to stay afloat.
What is the Characteristics of floating plants?
A plant's adaptations for floating in water are floating leaves and finely dissected leaves. These plants can only grow in water or in soil that is always saturated with water.
What adaptations help desert plants survive?
thick, waxy cuticles
