CBSE Diagrams for Class 11 Biology Important for Exams

CBSE Diagrams for Class 11 Biology

In class 11, there are 22 biology chapters included. We have try to attempt to include all the important diagrams for students for the purpose of exam. All the students need important neat labeled diagram for increasing the rank in the exam. From class 11 we have added 17 diagrams. Out of these 22 chapters most important chapter diagrams are drawn.

Chapter 2: Biological classification

In this chapter 1 diagram is more important from exam point of view. The first diagram is of bacteriophage, by which students came to know microscopic structure and features of micro-organism.

Figure 1: Bacteriophage

Chapter 5 : Morphology of flowering plants

This chapter includes morphology of all parts of flowering plant. Many of the part morphology we have learnt in lower classes, but in class 11 the diagram of gram seed and V.S of maize seed is more appropriate.

Figure 3: Gram seed

Chapter 6 : Anatomy of flowering plants

Along with morphology, anatomy of flowering plants should be equally studied. In anatomy of flowering plants microscopic structure of monocot root and dicot root is vital. By comparing between two morphology students can get to know about the morphological difference between monocot and dicot root. The same have done for dicot and monocot stem, so we have drawn the diagram of dicot and monocot stem.

Figure 4 : T.S of Dicot root

Chapter 7: Structural organization in animals

From this chapter, two diagrams are important and constantly asked in exam. From that 1st diagram is reproductive organs of an earthworm we have included and 2nd is alimentary canal of a cockroach.

Chapter 10: Cell cycle and cell division

As we know cell cycle is the marks giving topic so after the cell division next important process is cytokinesis in plant and animal cell, to understand such complex topic, we have explain in diagrammatic way.

Figure 10: cytokinesis in plant and animal cell

Chapter 11 :Transport in plants

To understand transportation mechanism in plant, first students must learn the concept of transport in cell, so 3 diagrams of plasmolysis we have illustrated.

Figure 11: Plasmolysis

Chapter 13 : Photosynthesis in higher plants

For photosynthesis to occur the main organelle present in plants is the chloroplast. By observing the chloroplast students can understand the parts of chloroplast.

Chapter 18: Body fluids and circulation

In this chapter standard ECG diagram is important which gives an idea about the normal and diseased patient ECG.

Chapter 19: Excretory products and their elimination

To understand the process of excretion the diagram of nephron is seems to be very helpful.

Figure 14: A nephron

Chapter 20: Locomotion and movement

One diagram is important and it is diagram of sarcomere of skeletal muscle showing dfferent regions.

Figure 15: sarcomere of skeletal muscle showing different regions

Chapter 21 :Neural control and coordination

In this chapter we have drawn the 2 diagrams such as the diagram of ear and schematic representation of eye.
