Why do artichokes have pointy needles in the leaves of their exterior?
Artichokes have thorny needles on their leaves as a defense mechanism to protect themselves from herbivores and predators. These needles discourage animals from eating them and help the plant conserve its energy for reproduction.
Plant needles are PROBABLY initially the result of?
Plant needles are probably initially the result of evolutionary adaptations to deter herbivores and reduce water loss. The needle shape helps protect plants from being eaten by animals, while the small surface area reduces water loss through evapotranspiration.
How cactus leaves work?
Typically the leaves of the plant play the greatest role in photosynthesis. However, on cacti, the needles are actually modified leaves. These needles are a characteristic of protection and cannot carry out photosynthesis due to little surface area. Therefore, it is the stem that does the photosynthesis for the plant.
Why you need to cut the brown leaves of a plant?
For some plants, the brown leaves slow the growing of the plant since brown leaves are basically dead leaves, but for most plants, people just cut them off because it looks more presentable that way. Usually they can live and grow with the brown leaves still there.
Does a pine needle have a stomata?
Yes, pine needles have stomata. Stomata are small pores found on the surface of leaves and needles that are involved in gas exchange, allowing the plant to take in carbon dioxide for photosynthesis and release oxygen and water vapor.
Name of the plant which reduces fertility of soil the leaves of this plant are bad for your lungs?
Tobacco
What are the different adaptations seen in plants?
There a plenty of adaptations plants have and this would be a long answer. with that said look at the cactus for example. This plant not only stores water within for a very long time but also has needles that do several different things. The needles of a cactus shade the the cactus, not having leaves means less need for water, the needles are able to slow water down when in falls on the plant, in order for the plant to collect as much water as possible and since this plant must store water for a long time, the needles protect it from predator's Also cactus are completely green, doing away with leaves and allowing the skin of the plant to do the photosynthesis needed.
What is the primary role of the needles of a scrub pine tree?
The "needles" on a pine tree or other conifer are the plant's leaves, where photosynthesis takes place. The needles are long and slender because of the environment of the trees. Needles lose less water and heat than typical leaves.

Can chickens eat brussel sprout leaves right off the plant?
Yes the plant is completely edible.
What are two traits of hemlock leaves?
They have flattened leaves which are called needles. The needles have two white lines beneath them. There are also cones that grow on these trees.
Various types of modified leaves?
The cactus modified leaves to sreate its spines, which are used for protection and storage of water. Carniverous plants have the "mouths," which are modified to help the plant obtain its needed nitrogen. Coniferous trees created needles instead of leaves. These needles are used for water storage and photosynthesis, and they have a very thick cuticle.

Why is it necessary to remove most of the leaves from a plant during transplant?
This reduces moisture loss and allows the roots to start getting into the soil.

What are the health benefits to the Hoodia plant?
The Hoodia plant is a spiny succulent plant with no leaves. It is found in South Africa and Namibia. This plant is said to have been used for many years for weight loss. It supposedly reduces ones appetite.
