Practical Biology for Advanced Level and Intermediate Students, Fifth Edition is an eight-part laboratory manual covering the syllabuses in biology of the advanced level students and other examinations of similar standard. The Introduction presents general instructions for practical work and for the keeping of practical notebooks and a list of apparatus and instruments required, as well as a summary of the characteristics of living organisms, the differences between plants and animals and the principles of plant classification.

Part I describes first the features and uses of a microscope, followed by a presentation of guidelines for the preparation of microscopical slides.

Parts II to IV are devoted to the evaluation of the form, structure, the microscopical structure of tissues and organs, and the very important aspect of their mode of functioning. These parts also consider other forms and modes of life, including insectivorous plants, fungi, bacteria, saprophytism, symbiosis, commensalism, and parasitism.

This book is directed toward advanced and intermediate level botany teachers and students. We are always looking for ways to improve customer experience on Elsevier. We would like to ask you for a moment of your time to fill in a short questionnaire, at the end of your visit.

Both private and regular students should prepare your lab observation and practical book in every classes and should be completed before going to your exam. As per the TN 11th New Blueprint, 20 marks for practical exam out of marks. Students can easily get full marks in public practical examination. This practical marks will be very helpful to increase your percentage. Attend your lab classes regularly and practice all the experiments. Do measurements and calculations carefully. You need to remember formulae and the steps to take readings to draw graph in physics.

Practical Biology

Biology is a practical science. Practical activities are not just motivational and fun: they also enable students to apply and extend their knowledge and understanding of biology in novel investigative situations, which can aid learning and memory, and stimulate interest. We have published a new set of resources to support the teaching of practical science for Key Stages The resources are part of the Practical Work for Learning projectwhich explores how three different teaching and learning approaches can be applied to practical work.

Materials Required A healthy potted plant, beaker, a pair of forceps, tripod stand, wire gauze, bunsen burner, black paper, paper clips, iodine solution, alcohol, water bath etc. Procedure I.

Important Note. Question 1: If plant is kept in a room with lights on, can it perform photosynthesis? Question 2: In which colour of light, plants can prepare their food best. Question 3: In which part of the plant the photolysis reaction initiates? Question 4: What is the original colour of iodine solution?

Question 1: What are the raw materials required by plants for photosynthesis? Question 2: What is the use of light in photosynthesis? In photolysis reaction, the water decomposes to form hydrogen and oxygen gas. Question 3: In a plant if there are no leaves for a short period of time, i.

Question 4: Why do we boil the leaves in alcohol solution? Question 5: Why do we need to decolourise the leaf? Question 6: Why should we always use water bath while boiling the leaf in alcohol solution? It will catch fire if we heat the beaker containing alcohol directly on the flames of burner. To prevent such accidents, it is always advised to use water bath. Question 1: What is meant by de-starching? Why do plants get de-starched when kept in continuous darkness for about forty eight hours?

When plants are kept in continuous darkness for about forty eight hours, all the starch present in them is used up for various biological processes and no new starch is formed due to absence of light. Question 2: Will you get the same result if you perform the experiment without de-starching the plant?

Give reason. If the starch is already present in the plant, the experiment will not give the fair test. Question 3: Why do we warm the leaves in alcohol? Question 5: Why do we keep the experimental plant in bright sunlight? Question 6: Can this experiment be performed with a de-starched leaf detached from the plant? Give reasons.

Questions based on Procedural and Manipulative Skills Question 1: The first step in photosynthesis is a convert light energy into chemical energy b reduction of C0 2 gas to carbohydrates c photolysis of water d absorption of light energy by chlorophyll. Question 2: In desert plants, the first step of photosynthesis can be a absorption of sunlight b photolysis of water c intake of C0 2 at night d convert light energy into chemical energy.

Question 3: In an experiment to show that sunlight is necessary for photosynthesis, the leaf is boiled in alcohol for a few minutes using a water bath. It is essential because: a alcohol is highly volatile b the steam from water bath heats the leaf rapidly c steam from water bath dissolves the chlorophyll d alcohol is flammable. This is to: a deactivate the chloroplast b destarch leaves c activate chloroplasts d prepare leaves for photosynthesis.

The correct order is: I. Question 7: Before carrying out the test for the presence of starch in a leaf-on exposure to sunlight, the leaf is put into alcohol contained in a beaker and boiled over a water bath. This step is carried out to a extract starch b dissolve chlorophyll c allow water to move into the leaf d make membrane of leaf cells more permeable.

Question 8: A student performed the starch test on a leaf, some steps involved are shown below: The correct sequence of steps should be: a iviiiiii b iiiiiiiv c iiiiiivi d iiiiivii. Question 9: What is the right procedure to remove chlorophyll from a destarched leaf?To browse Academia. Skip to main content. Log In Sign Up. XI Sci. Biology Practical Handbook Prof. Mamta R.

Learning does not mean only gaining knowledge about facts and principles rather it is a path which is informed by scientific truths, verified experimentally.

The laboratory is important for making the study complete, especially for a subject like Science and Biology. CBSE has included the practicals in secondary class intending to make students familiarised with the basic tools and techniques used in the labs. By performing the experiments, students will know the concept in a better way as they can now view the changes happening in front of their eyes. Their basics will become solid as they will learn by doing things. By doing this activity they will also get generated their interest in the subject.

Students will develop questioning skills and start studying from a scientific perspective. Home Cbse Lab Manual English 12th 1.
