The right response is sugarcane, which is (C). Sugarcane is a c4 plant, which means that its chloroplasts may take on two different forms.
Why does sugarcane show chloroplast dimorphism?
- The phenomenon known as chloroplast dimorphism describes the occurrence of granulated chloroplasts in leaves that are devoid of starch and include bundles of chloroplasts.
- Sugarcane has chloroplasts that can store starch but no grana in the cells that make up its vascular bundle sheath.
- Since sugarcane is a c4 plant, it displays the chloroplast dimorphism that is characteristic of such plants.
Why is Amaranthus a dimorphic chloroplast?
Because it is a C4 plant, amaranthus has two different types of chloroplasts in its cells. – Because the process of fixing carbon with carbon-4 takes more ATP than the process of fixing carbon with carbon-3, plants are able to repair carbon more effectively under conditions when there is a lack of nitrogen or carbon dioxide.
What type of dimorphism is present in C4 plants?
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 dimorphism of chloroplast?
Dimorphic chloroplasts are chloroplasts that are concentrated on two types of cells with differing sizes and shapes. These two cell types are referred to as ″dimorphs.″ Grana-containing mesophyll cells are where you will find it.

Which of the following plants exhibit dimorphic?
The correct answer is option 1. The sorghum plant is a C4 organism. Dimporphic chloroplasts are chloroplasts that have a structure and size that are distinct from one another, for example, one is huge while the other is little.
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.
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).
Why do plants such as maize and sugarcane have dimorphic chloroplasts?
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 an example of a C4 plant?
C4 plants, such as maize, sugarcane, and sorghum, circumvent the need for photorespiration by employing a different enzyme known as PEP during the initial stage of the carbon-fixation process. This process takes place in the mesophyll cells, which are situated in close proximity to the stomata, the openings in the plant through which carbon dioxide and oxygen are taken in.
Why do C4 plants have two types of chloroplasts?
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).
Is bell pepper a C4 plant?
Two of the vegetables grown in the greenhouse are tomatoes and bell peppers. They are referred to as C3 plants.
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.
Do C4 plants have more chloroplasts?
The mesophyll cells of closely related C4 plants have a lower chloroplast content than the mesophyll cells of C3 plants. Plant Cell Environ.
How many plants are C4 plants?
According to the APG IV classification, there are around 8,100 recognized C4 species, and these species are divided among at least 61 separate evolutionary lineages that reside within 19 families of flowering plants. Not just useful crops like maize, sorghum, and sugarcane, but also noxious weeds and invasive plant species are included in this category.
Is tomato a C4 plant?
Both tomato plants, which are classified as C3 plants, and maize plants, which are classified as C4 plants, were cultivated in a nutrient solution to which triacontanol was added twice per week.
Where is Kranz anatomy found?
Kranz anatomy is a subcategory of anatomy that may be found exclusively in the leaves of C4 plants.
What do CAM plants do at night?
The stomata of CAM plants are able to open up at night, enabling carbon dioxide start text, C, O, end text, start subscript, 2, end subscript to enter the leaves by diffusion.
