The correct answer is:
Option 1: Maize
Kranz anatomy is a specialized leaf structure found in plants that perform C4 photosynthesis, such as maize (corn), sorghum, and sugarcane.
In Kranz anatomy, the leaf has two distinct types of cells:
Bundle sheath cells: These cells are located around the vascular bundles and contain large amounts of chloroplasts for the Calvin cycle.
Mesophyll cells: These cells are located between the epidermis and bundle sheath and are involved in the initial fixation of carbon dioxide.
This adaptation helps C4 plants minimize photorespiration and efficiently fix carbon in hot, dry environments.
The other options (Tomato, Potato, Pea) are C3 plants and do not exhibit Kranz anatomy.
Kranz anatomy is a specialized leaf structure found in C4 plants. It is characterized by two distinct types of photosynthetic cells:
This unique arrangement is advantageous for C4 photosynthesis, as it concentrates CO2 around the enzyme RuBisCO in the bundle sheath cells, minimizing photorespiration.
Now, let's consider which of the given plants are C4 plants:
Therefore, the correct answer is Maize.
A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
