Practicals in Biology for Class 10th

Biology is a fascinating subject that deals with the study of living organisms and their interactions with the environment. Class 10th biology practicals are an essential part of the curriculum, as they help students to gain a better understanding of the concepts and principles taught in the classroom. Here are some of the practicals that students can perform as part of their biology curriculum.

Preparing temporary mounts of plant and animal tissues

This practical involves the preparation of temporary mounts of plant and animal tissues for microscopic observation. Students can use onion peel, human cheek cells, and Elodea leaf cells to prepare the mounts. They can then observe the structures of the cells under a microscope and draw diagrams of what they observe.

Identification of tissues in plants and animals

This practical involves the identification of different types of tissues in plants and animals. Students can use prepared slides of different plant and animal tissues, such as parenchyma, collenchyma, sclerenchyma, and epidermis, to identify the tissues and their functions.

Study of osmosis through potato slices

This practical involves the study of osmosis, which is the movement of water molecules from a high concentration to a low concentration across a semi-permeable membrane. Students can use slices of potatoes and varying concentrations of salt solutions to observe the effect of osmosis on the potato slices.

Study of the digestive system of humans

This practical involves the study of the digestive system of humans. Students can use charts and models to learn about the different organs involved in the digestive process, such as the mouth, esophagus, stomach, small intestine, and large intestine.

Conclusion

Biology practicals for class 10th are an essential part of the curriculum, as they help students to gain a better understanding of the concepts and principles taught in the classroom. By performing these practicals, students can develop their analytical and observational skills and learn about the natural world around them.
