Growth and development are fundamental concepts in Form Four Biology, explaining how organisms increase in size and become more complex. This PDF note clearly defines growth as a permanent increase in size and dry mass, and development as changes in complexity through cell differentiation.
The material explains positive and negative growth, along with key processes such as cell division, cell enlargement, cell assimilation, and cell differentiation. It also highlights the importance of growth in increasing body size, enabling specialization, and supporting adaptation to different environments.
In addition, the notes cover various types of growth, including isometric, allometric, diffuse, localized, determinate, indeterminate, and intermittent growth, with clear examples for better understanding.
Designed for exam preparation, this resource simplifies concepts and provides structured content for quick revision.
