What is the purpose of needle like leaves on some trees?

What is the purpose of needle like leaves on some trees?

1) Needle shape helps the leaves to retain moisture, preventing water loss as the stomatas are sunken and tightly packed in needle like leaves. 2)Needle shape gives them ability to shed snow as pine trees are found in cold regions.

What might be one of the biggest advantages of the needle shaped leaves of the pine trees?

What might be one of the biggest advantages of the needle shaped leaves of the pine trees? Needle-shaped leaves reduced the water loss so much that the trees did not have to drop the leaves in the winter months.

How are needle shaped leaves adapted to dry conditions?

The needles of pines, like those of other conifers, are well-adapted for growth in dry environments. In particular, the outer surface of pine needles has a thick waxy layer, called a cuticle, which reduces evaporative water loss.

What is the advantage of trees having needle shaped leaves quizlet?

What is the advantage of trees having needle-shaped leaves? – The leaves lose water at a greater rate. – The leaves are more likely to be eaten by herbivores. – Needle-shaped leaves have a greater surface or photosynthesis than broad, flat leaves.

Which tree has leaves shaped like needles?

Pines, spruces, firs and cedars are some trees with needle shaped leaves. The leaves have needle shape because of dryness in air to prevent the water loss due to transpiration.

What shape are Pinus leaves found?

Pinus is a large, perennial, evergreen plant. 2. Branches grow spirally and thus the plant gives the appearance of a conical or pyramidal structure.

Are pine needles good for anything?

Pine Needle Uses The needles make excellent fire starters, flavoring for teas and vinegars, grill smoke to season meats, air fresheners, and, of course, mulch. They have many medicinal properties as well. Outside of garden use, a tea made from the leaves is not only delicious but the scent can help clear sinuses.

Why do gymnosperms have needle like leaves?

Why do some trees have needles instead of broad, flat leaves? Conifers, or cone-bearing trees, evolved to have needles that retain more water and seeds that could hang out until there was enough moisture to take root. It may not seem like it, but needles are leaves.

What is a plant with needle like leaves called?

Coniferous trees have small, waxy and usually narrow leaves (needles or flat scales). ‘Coniferous’ means that it is a cone-bearing tree. The most common conifers are spruces, pines and firs. Alternative names used for coniferous trees are evergreens, softwoods and (appropriately enough) conifers.

What is the advantage for a plant to produce broad leaves compared to narrow needle like leaves?

Broad-leaves are usually grown quickly and don’t take much energy for plants to grow. They are also often easily eaten by herbivores but are very efficient at photosynthesizing because of their large surface area.

Why are needle shaped leaves better than regular leaves?

But their needles still offer some nifty advantages over leaves—especially in tough climates or soil conditions: Needles have a thick, waxy coating that retains more water than a regular leaf. Needles have lower wind resistance than big, flat leaves, so they’re less likely to make the tree fall over during a big storm. Click to see full answer.

Why do trees have needles in the fall?

Since needles don’t shed each fall they can capture sunlight for nearly the entire year. Needles can survive ice and snow. Needles have lower wind resistance than big, flat leaves, so they’re less likely to make the tree fall over during a big storm. Needles are tough for insects to eat.

How does a needle tree keep water in the leaves?

Retained Water. However, needles have pit-like stomatae — holes through which trees exchange water and gasses — that collect water and bring it into the leaf. Furthermore, these needles are covered with a waxy coating, preventing water loss through transpiration.

Why do coniferous trees have needle shaped leaves?

Coniferous trees adapted with their needle shaped leaves because to survive in cold climatic conditions. Pines and cedars are example for coniferous trees.
