Biology (Grade VII)
Grade VII
Tk. 5,000
Tk. 4,500
Before 10 July
Overview
Explore what makes life possible—from cells and enzymes to organs and ecosystems.
The Grade VII Biology syllabus provides a comprehensive understanding of life processes, organismal structure, and diversity. The chart below highlights the key learning areas:
Identify key structures in plant and animal cells and relate them to specific functions- Understand how diffusion, osmosis, and active transport move substances into and out of cells
- Explore the roles of carbohydrates, proteins, lipids, and DNA in biological systems
- Describe how enzymes catalyse metabolic reactions with specificity and efficiency
- Investigate the process and importance of photosynthesis in plants and the role of minerals
- Trace the transport of water and nutrients through plant structures like xylem and phloem
- Understand human nutrition, including food groups, digestion, enzymes, and nutrient absorption
- Compare aerobic and anaerobic respiration and understand their role in energy release
- Describe the structure and function of the circulatory, respiratory, and excretory systems
- Learn how the nervous and hormonal systems coordinate internal responses and maintain balance
- Understand classification systems and how traits are passed through genetic inheritance
- Explore how variation arises within species and how organisms are grouped by features

Assessment and Practice
Regular topic tests provide students with timely feedback, while dedicated consolidation weeks encourage application of concepts across topics. A structured midterm exam assesses core understanding, and extensive spiral revision ensures long-term retention. The course concludes with mock exams that prepare students for formal assessments, focusing on critical thinking, analysis, and accurate biological communication.
Course Structure Overview
This comprehensive plan guides students through the complexities of biological systems, from cellular processes to human physiology and genetics, incorporating regular assessments and spiral revision.
