Study Notes

Cell as the Basic Unit of Life

Cell: The smallest unit of life.
Ribosomes: Function to synthesize proteins.
Mitochondria: Responsible for cellular respiration, producing energy (ATP) for the cell.

Human Body Systems

Digestive System: Responsible for breaking down food into nutrients the body can absorb.
Blood Vessels: Include arteries, veins, and capillaries.

Biology and Genetics

Biology Chapter 2: Focuses on the study of cells in living organisms.
Class 12 Biology: Includes the study of meiosis, the process of cell division that leads to the formation of gametes (sperm and egg cells), contributing to genetic diversity.
Taxonomy: The study of classification and evolutionary history of living organisms.
