Principles of Biotechnology - According to modern biotechnology, some of the main principles are genetic engineering and bioprocess engineering. Genetic engineering is used to modify the DNA of the target organisms by changing the phenotype of the organism. Bioprocess engineering maintains the sterile condition to support the growth of large quantities of desired microbes and other eukaryotic cells.
- Which is used for the production of new or modified biotechnology products like antibiotics, enzymes, and vaccines. Genetic engineering primarily includes the isolation of DNA fragments from the donor organism. Then it is inserted into the vector DNA, later it is transferred into an appropriate host. Then cloning of recombinant DNA in the host organism. Later culture of the transformed cells in a nutrient medium and extraction of the desired product. With some of the properties like - It should be smaller in size but should be able to carry a large DNA insert. The cloning vector should have the origin of replication so that it can autonomously replicate in the host organism. It should have a restriction site with a selectable marker to screen recombinant organisms.
- And It should also possess multiple cloning sites. Conclusion By going through all the important questions for Class 12 Biology Chapter 11, students can prepare and revise the concepts for their 12th boards and competitive exams. It will also help them to understand the fundamental topics covered in the chapter Biotechnology Principle and Its Processes. These important questions are designed in such a way that it not only covers the conceptual parts but also the problem-solving and applicational approach too.
- The answers of Biotechnology Principles and processes Class 12 important questions are detailed and connected to the theory so students can get a clear idea about the topics by referring to these questions and answers.

It occurs usually at night. It occurs usually during the day. Water is lost from the leaves in the form of liquid droplets. Water is lost from the leaves in the form of water vapour. It occurs through the vein endings of leaves. It occurs through the stomata. It is an uncontrolled process. It is a controlled process. Page No Briefly describe water potential. What are the factors affecting it? Answer: Water potential quantifies the tendency of water to move from one part to the other during various cellular processes such as diffusion, osmosis, etc.- The water potential of pure water is always taken as zero at standard temperature and pressure. The water potential of pure water or a solution increases on the application of pressure values more than atmospheric pressure. It is termed as pressure potential. This pressure potential plays a major role in the ascent of water through the stem. Page No Question 7: What happens when a pressure greater than the atmospheric pressure is applied to pure water or a solution? Answer: The water potential of pure water or a solution increases on the application of pressure values more than atmospheric pressure. For example: when water diffuses into a plant cell, it causes pressure to build up against the cell wall. This makes the cell wall turgid. This pressure is termed as pressure potential and has a positive value.
- Page No Question 8: a With the help of well-labelled diagrams, describe the process of plasmolysis in plants, giving appropriate examples. Answer: a Plasmolysis can be defined as the shrinkage of the cytoplasm of a plant cell, away from its cell wall and toward the centre. It occurs because of the movement of water from the intracellular space to the outer-cellular space. This happens when the plant cell is placed in a hypertonic solution i. This causes the water to move out of the cell and toward the solution. The cytoplasm of the cell shrinks and the cell is said to be plasmolysed. This process can be observed in an onion peel kept in a highly concentrated salt solution.
- The entry of water in the plant cell exerts pressure on the rigid cell wall. This is called turgor pressure. As a result of its rigid cell wall, the plant cell does not burst. Page No How is the mycorrhizal association helpful in absorption of water and minerals in plants? Answer: Mycorrhiza is a symbiotic association of fungi with the root systems of some plants. The fungal hyphae either form a dense network around the young roots or they penetrate the cells of the roots.
Oxford University Press | Online Resource Centre | Multiple Choice Questions
The large surface area of the fungal hyphae is helpful in increasing the absorption of water and minerals from the soil. In return, they get sugar and nitrogenous compounds from the host plants. The mycorrhizal association is obligate in some plants. For example, Pinus seeds do not germinate and establish in the absence of mycorrhizal. Page No What role does root pressure play in water movement in plants? Answer: Root pressure is the positive pressure that develops in the roots of plants by the active absorption of nutrients from the soil. When the nutrients are actively absorbed by root hairs, water along with minerals increases the pressure in the xylem. This pressure pushes the water up to small heights. Root pressure can be observed experimentally by cutting the stem of a well-watered plant on a humid day. When the stem is cut, the solution oozes from the cut end.
