Which Of The Following Features Is Associated With C4 Plant?

There are two key adaptations that are responsible for C4 plants being able to achieve this: To begin, the first step in the process of carbon fixation is carried out by C4 plants using a different enzyme. Phosphoenolpyruvate (PEP) carboxylase is the name of this enzyme, and it does not have any oxygenase activity and has a far greater affinity for CO2 than rubisco does.

C4 plants are distinctive in that they have two distinct kinds of photosynthetic cells. The bundle-sheath, which is a layer of cells that surrounds the vascular bundle, is a structural element that is present in most plants; however, only C4 plants have chloroplasts in this layer of cells.

What are the characteristics of C4 photosynthesis?

C4 Plants Have the Following Traits: C4 photosynthesis allows C4 plants to circumvent the need for photorespiration. During the Calvin cycle, C4 plants produce a sugar with four carbon atoms. C4 plants generate more usable energy than C3 plants and thrive in hot, arid environments. C4 plants also require less water.

Which of the following is an example of a C4 plant?

  1. A plant that converts carbon dioxide into sugar molecules with four carbon atoms and then participates in the Calvin cycle is referred to as a C4 plant.
  2. These plants are able to produce a great deal of energy despite the hot and dry conditions in which they thrive.
  3. Corn, pineapple, and sugar cane are just a few examples of foods that come from C4 plants.

Therefore, the response that is right is ″sugarcane.″

What is the C4 carbon fixation pathway in plants?

C4 plants make use of the C4 carbon fixation pathway in order to boost their photosynthetic efficiency. This is accomplished by lowering or eliminating photorespiration, a process that takes place primarily in conditions characterized by a low atmospheric CO. 2 concentration, high light, high temperature, drought, and saltiness.

What is the function of C4 cells in plants?

  1. Photosynthesis normally takes place in the cells that are found closer to the surface of a plant leaf.
  2. These cells are known as epidermal cells.
  3. On the other hand, these cells in C4 plants are open to oxygen and do not contain RuBisCO, which prevents photosynthesis from occurring.

3.The CO 2 combines with another carbon component to produce oxaloacetic acid, which is a substance having the formula C4H8O.

What is the special feature of the leaves of C4 plants?

  1. When a four-carbon molecule is created during C4 photosynthesis, the distinctive structure of the leaf makes it possible for carbon dioxide to condense in the ″bundle sheath″ cells that surround Rubisco.
  2. This structure is responsible for delivering carbon dioxide directly to Rubisco, which eliminates the requirement for photorespiration and prevents Rubisco from coming into touch with oxygen.

What are the characteristics features of C4 leaf anatomy?

Typically, C4 leaves will have an architecture of the Kranz type. This means that the vascular bundle will be surrounded by organelle-rich bundle sheath cells, and this tissue layer will then be further surrounded by mesophyll cells that are organized in a radial pattern.

What is characteristic of C4 plants quizlet?

Which of the following best describes the features of plants that have the C4 pathway? Oxaloacetate is a kind of short-term storage for carbon dioxide that C4 plants use.

How do you identify C4 plants?

C4 plants, on the other hand, are plants that employ the C4 pathway during the dark response. This is how C4 plants are classified. These plants have chloroplasts that can be either of two different shapes, and in contrast to C3 plants, the leaves of C4 plants have kranz architecture.

Which is a C4 plant?

C4 plants, of which there are numerous types of tropical grasses, are among the most significant agricultural species in the world (maize and sugarcane).

Why do C4 plants have Kranz anatomy?

The Benefits of Using Kranz Anatomy It offers an ideal location for the CO2 to be concentrated within the plants, namely in the area around the RuBisCO. It contributes to the reduction of the effects of photorespiration. With the assistance of the bundle sheath cells that are present in C4 plants, it makes it possible for carbon dioxide to be fixed twice within those plants.

Why do C4 plants show Kranz anatomy?

  1. Kranz anatomy is a unique structure that is seen in C4 plants.
  2. In this structure, the mesophyll cells are arranged in a ring-like way around the bundle-sheath cells.
  3. When compared to the amount of chloroplasts found in mesophyll cells, the number of chloroplasts found in bundle-sheath cells is significantly higher.

This is present in C4 grasses like maize, as well as in a few dicotyledonous plants.

What are C4 plants quizlet?

C4 plants are able to concentrate CO2 by dividing portions of certain cycles up between the cells of the leaf. As a CO2 shuttle, 4-carbon oxaloacetate can also be used. The presence of oxygen within the plant cell, which triggers a response from the plant to stop the process of photosynthesis, most likely in an effort to defend itself.

Do C4 plants have RuBisCO?

Yes, RuBisCO may be found in both C3 and C4 plants. The Calvin cycle, which is part of both of the routes that lead to carbon fixation, is driven by the enzyme RuBisCO, which is the primary enzyme. The placement of RuBisCO is different from one another. In C3 plants, it can be found in the cells of the mesophyll, but in C4 plants, it may be found in the cells of the bundle sheath.

C3 vs C4 Plants

C3 Plants C4 Plants
Photorespiration is not suppressed Photorespiration is suppressed
Carbon dioxide fixation is slow. Carbon dioxide fixation is faster.
Photosynthesis occurs when stomata are open Photosynthesis occurs even when stomata are closed.

What is true about C4 plants?

  1. The Definition of C4 Plants Before beginning the Calvin-Benson cycle of photosynthesis, a C4 plant converts the carbon dioxide that it takes in from the atmosphere into a molecule that has four carbon atoms.
  2. It is also possible to refer to the C4 route as the Hatch–Slack pathway.
  3. It is one of the three photosynthetic routes in plants that have been found, and it is responsible for the fixation of carbon.

What happens in C4 plants?

Mesophyll cells are responsible for the first stage of carbon fixation that occurs in the C4 pathway, while bundle-sheath cells are the ones that carry out the Calvin cycle. PEP carboxylase is responsible for the production of oxaloacetate by the attachment of an incoming carbon dioxide molecule to the three-carbon compound PEP (a four-carbon molecule).

What does C4 stand for?

C-4 is defined as a powerful explosive that is made up of several different compounds that give it a moldable and plastic quality. I was able to get a hold of a chunk of the C-4 plastic explosive before it went off. It was approximately the size of a baseball.
