This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
The correct response is an opuntia. As a defense mechanism against water loss through transpiration, areole leaves and other types of leaves can become transformed into spines.
Why are the leaves of Opuntia transformed into these forms?
The decreased leaves of an opuntia can be seen as the spines that are present on the plant. Spines are formed from the modified leaf portions in order to prevent the plants from being eaten by animals and from losing too much water through transpiration.
Which component of the Opuntia plant is altered?
The stem of the opuntia plant not only stores the products of photosynthesis but also serves the role of transporting water.In reality, spines are formed through the transformation of leaves. It provides the plant portion with both defense and protection.
Is the leaf of the opuntia altered?
Thus, the response that should be chosen is option A. The spines on opuntia are actually a modified form of the leaf.
In what form do the leaves of a cactus eventually transform?
Spines are transformed from the leaves of cactus plants. It is the green stem that is responsible for carrying out all of the tasks that are normally carried out by the leaves, including photosynthesis.
Opuntia is distinguished by the transformation of its areoles’ leaves into

What are the benefits of having leaves that have been transformed into spines?
The majority of cactus species have lost their true leaves and now only hold on to their spines, which are highly modified forms of leaves. In addition to acting as a deterrent against animals, the spines on a cactus can also reduce the amount of wind that blows past the plant and provide some degree of shade. When there are no leaves present, the photosynthesis process is carried out by the expanded stems.
Which type of plant undergoes leaf transformation into tendrils?
Only the leaflets that are at the very end of the pea plant’s stem can undergo the transformation into tendrils. In some plants, such as the yellow vetch (Lathyrus aphaca), the entire leaf transforms into a tendril, while the stipules expand and take over the role of carrying out photosynthesis.
Why do the prickly pear’s leaves morph into spines instead of remaining leaves?
Spines are the common name for the sharp, pointed structures that can develop on the leaves of certain plants in order to serve as a form of defense against predators. The minute leaves of the axillary bud of the prickly pear are transformed into spines in this way. The axillary bud that they carry in their axil is the target of their defense mechanism, which is their function.
Why do the cactus plant’s leaves turn into spines instead of remaining leaves?
In order to reduce the amount of water that can be lost by evaporation, the spines on its leaves have been reduced to an incredibly minute size. Because the photosynthetic process is carried out by the stem, the plant is able to live in arid environments. As a result, the cactus is the option that should be chosen here.
Which type of modified stem is typically utilized for the purpose of storing food?
A bulb is a modification of the stem that stores food and is characterized by expanded fleshy leaves that emerge from or surround the base of the stem. Bulbs can also be found surrounding the base of the stem. Tendrils, thorns, bulbils, and cladodes are all examples of stem alterations that grow in an upward direction.
Are there any leaves on an opuntia plant?
Opuntia is a type of plant known as a xerophyte, which means that its leaves have evolved into spines to slow down the pace at which water is lost by transpiration, and they do not participate in photosynthesis at all…. While true leaves have been reduced to scales or spines, these structures can be found in the axils of the scale leaves.
Are the tendrils that grow on cucumbers a form of stem modification?
Tendrils are structures that are spirally coiled or have a claw-like appearance, and they are used by plants to grip an object or adhere to it. It’s possible that a tendril is a modified stem or even a modified leaf. Tendrils are modified versions of leaves that are found in the family Cucurbitaceae, which includes cucumbers.
Which of the following is an altered leaf?
The pitcher-like structures that are characteristic of Nepenthes are derived from the leaves. As a result of this, it is also known as the pitcher plant. The upper leaflet of Pisum sativum, more commonly known as pea, transforms into a tendril. Cactus plants are characterized by the transformation of their leaves into spines. They contribute to the protection.
What exactly is an example of cladode?
Asparagus (Asparagus) shoots, on the left, Engelmann prickly pear (Opuntia engelmannii), in the center, and butcher’s broom (Ruscus aculeatus), on the right. These are all examples of plants that have cladodes. Although it does not produce leaves, the stem will eventually grow flattened and take on the appearance of leaves as it takes over the plant’s photosynthetic tasks.
Why do we not consider sunflowers to be flowers?
The sunflower is technically not a flower but rather a type of inflorescence known as a capitulum. This type of inflorescence has a flattened receptacle. It produces a large number of florets that are sessile and very tiny. The floret that is the youngest can be found in the middle, while the floret that is the oldest can be found on the outside. The term “involucre” refers to the surrounding bracts that cover the entire cluster of florets.
Is the primary purpose of the leaf to provide shade?
Function of the leaf
The process of photosynthesis is the primary means through which leaves contribute to the production of food for the plant… Stomata, which are pores in the leaf surface, are responsible for the release of oxygen into the surrounding air. photosynthesis. Sugars are produced by green plants like trees through the interaction of carbon dioxide, sunshine, and water.
What exactly is the function of a cactus that has been altered?
The modification of the leaves of cactus plants into spines has two purposes: it enables the plants to reduce the amount of water lost through transpiration, and it also protects the plants from being consumed by animals.
What are the two primary roles that leaves play in the plant?
The processes of photosynthesis and transpiration are the two primary jobs that are carried out by the leaf. In the presence of light, the process known as photosynthesis is how green plants create their own sustenance from carbon dioxide and water.
How are leaves altered so that they can serve a certain purpose?
Leaves can be adapted to take the form of spines, which not only prevent the loss of water but also serve as a defense mechanism. Some of the stems become changed into tendrils, which are used to sustain the plant. There are some leaves that are particularly thick, which assists in water storage. Some of them have been engineered to catch and eat insects.
Is it possible for it to transform into spines?
Explanation: In order to prevent water loss through transpiration and facilitate adaption to arid conditions, the leaves of opuntia plants transform into spines. The photosynthetic process is carried out by the stems of this plant, which have the appearance of leaves and are referred to as phylloclades.
What exactly is the function of the veins in the leaves?
It is the veins in a leaf that make up the vascular structure of the organ. These veins extend into the leaf via the petiole and are responsible for the transport of water and nutrients between the leaf and the stem. Veins also play an important part in the preservation of the leaf’s capacity for photosynthesis and water balance.
What do you call the configuration where leaves are arranged on a stem?
The classification of leaves as alternate, spiral, opposite, or whorled is referred to as phyllotaxy. The arrangement of leaves on a stem is known as the arrangement of leaves on a stem.
Which kinds of things have tendrils as examples?
It is possible that its anatomy is composed of stem tissue or leafstalk tissue. Some examples of plants that produce tendrils are the grape, as well as members of the family Cucurbitaceae, which includes squash and melons, the sweet pea (Lathyrus odoratus), and passionflowers.
What portion of the leaf is referred to as the petiole?
The blade of the leaf and the leaf base are connected by a stalk known as the petiole. The blade, which has a green appearance and is flattened in a plane that is perpendicular to the stem, serves as the primary photosynthetic surface of the plant.
