This phenomenon, known as chloroplast dimorphism, is unique to C4 plants, such as amaranthus, sugarcane, and maize, amongst others.
What is a dimorphic chloroplast?
A dimorphic chloroplast is one that has two structurally distinct chloroplasts within the same plant at the same time. The presence of this kind of dimorphism can be seen in plants that engage in a particular kind of carbon fixing. – In C4 plants, chloroplasts are clustered in two sheaths of cells that are concentric to each other and surround each vascular bundle.
What is chloroplast dimorphism in Amaranthus?
The chloroplasts found in mesophyll cells are devoid of grana and starch, whereas the chloroplasts found in bundle sheath cells are devoid of grana but abundant in starch. This characteristic is referred to as chloroplast dimorphism. C4 plants are recognizable by the presence of dimorphic chloroplasts in their cells. A C4 plant is an amaranthus plant.
Which chloroplast dimorphism does the plant sugarcane show?
Since sugarcane is a c4 plant, it displays the chloroplast dimorphism that is characteristic of such plants. Therefore, option D is the one to pick. Find the answer to any question you may have regarding photosynthesis in higher plants with:
Which of the following plant cell types contains chloroplast with abundant Grana?
Bundle sheath cells and mesophyll cells are the two types of chloroplast-containing cells that they have in their bodies. The chloroplasts of bundle sheath cells are devoid of grana, but the chloroplasts of mesophyll cells are rich in grana. Therefore, the response that is right is ″Sugarcane.″
Which of the following plants exhibit dimorphic chloroplast 1 sorghum 2 tomato 3 bell pepper 4 Opuntia?
The sugarcane plant, often known as the C(4) plant, has chloroplast dimorphism.
Which of the following possess dimorphic leaves?
Both Pinus and Gnetum have leaves that are dimorphic, which means that they have two different types of leaves: scale leaves and foliage leaves.
What is the function of dimorphic chloroplast in C4 plants?
Chloroplasts in Single-Cell C4 Plants and Maize Exhibit a Dimorphic Structure C4 plants include two distinct kinds of chloroplasts: one is responsible for the fixation of carbon dioxide, while the other makes it possible for rubisco to work at higher CO2 partial pressures (Edwards et al., 2001).
What is Kranz anatomy?
Kranz anatomy is a unique structure that is seen in C4 plants.In this structure, the mesophyll cells are arranged in a ring-like way around the bundle-sheath cells.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.

In which group of plants do dimorphic chloroplast occur name any two such plants?
Maize, sugarcane, and sorghum are examples of monocot plants. Euphorbia, Chenopodium, Atriplex, and Amaranthus are all examples of dicot plants. Therefore, sugarcane contains dimorphic chloroplasts in some of its cells. Because of this, the appropriate response is option (A).
Where is dimorphic chloroplast found?
The chloroplasts of mesophyll cells do not contain grana and are devoid of starch, whereas the chloroplasts of bundle sheath cells do not contain grana and are rich in starch. This characteristic is referred to as chloroplast dimorphism. The chloroplasts of C4 plants display dimorphism, but the chloroplasts of C3 and CAM plants do not.
What are dimorphic plants?
A plant’s root system is said to be dimorphic if it has two distinctly different root morphologies, each of which is designed to serve a different role in the plant.
What is a dimorphic flower?
Introduction. Flowers, which are the reproductive organs of plants, display a variety of sexually dimorphic characteristics1,2,3,4,5,6,7,8. Sexual dimorphism is a common type of intraspecific variation. In order for pollen to be transferred from plant to plant, plants frequently rely on animal pollinators.
Why do plants like maize and sugarcane have dimorphic chloroplast?
These bundle sheath cells contain chloroplast that does not have grana, yet the mesophyll cells that are close to them have an abundance of grana. Dimorphic chloroplasts are present in C4 plants, which contributes to their better output of biomass, absence of photorespiration, and endurance of high temperatures.
What is a C4 plant examples?
As a consequence of this, C4 plants have a tendency to produce more fruit than C3 plants in conditions characterized by high light and warmth. Corn, sorghum, sugarcane, millet, and switchgrass are all types of plants that belong to the C4 family.
Are fungi dimorphic?
Abstract. During the course of their existence, dimorphic fungi are able to transition between two morphologies, namely yeast and hyphae. These organisms are known as ″splitters.″ Temperature is responsible for inducing morphological changes in fungi that are thermally dimorphic.
What are Kranz 2 examples?
As an illustration, corn, pineapple, and sugarcane are all examples of plants that have Kranz anatomy.
What are C3 and C4 plants?
Definition. The dark reaction of photosynthesis, also known as the C3 pathway or the Calvin cycle, is carried out by C3 plants. The dark reaction of photosynthesis is carried out by C4 plants via the C4 route, also known as the Hatch-Slack Pathway. Season. These are plants that thrive during the chilly season and are typically found in locations that receive a lot of moisture.
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.
