Cell Biology
The study of structural and functional units of life, including cell division (mitosis and meiosis) and the cellular basis of living organisms.
Stem Cells
Undifferentiated cells present in multicellular organisms that can renew themselves through mitosis and differentiate into specialized cell types.
Tissue Culture
A technique of growing plant cells, tissues, or organs on a nutrient-enriched artificial medium under aseptic conditions to produce new plants.
Biotechnology
The integration of natural science and organisms to produce products and processes for agriculture, medicine, and industrial applications.
Genetically Modified Crops (Bt Crops)
Crops whose DNA has been altered using genetic engineering techniques to provide resistance against pests and environmental stresses.

Common question types include short notes on stem cells, applications of biotechnology, differences between various types of biotechnology, and reasoning-based questions on the importance of organ donation.
Frequently Asked Questions
What is the difference between embryonic stem cells and adult stem cells?
Embryonic stem cells are pluripotent and can develop into any type of body cell, whereas adult stem cells are multipotent and are limited to differentiating into specific cell types related to their tissue of origin.
Why is biotechnology important in agriculture?
Biotechnology helps in developing pest-resistant crops like Bt cotton, drought-tolerant varieties, and nutrient-enriched foods like Golden Rice, thereby increasing agricultural yield and quality.
What is meant by organ transplantation?
Organ transplantation is a medical procedure where a failing or damaged organ in a human body is replaced with a healthy organ obtained from a living or deceased donor.
