Introduction to Cell Biology
Introduction to the basic concepts of cell biology, covering the structure and functions of animal and plant cells, including the nucleus, cytoplasm, ribosomes, mitochondria, and cell membrane.
Specialized Cells
Discussing specialized cells like sperm cells and rainbow cells, highlighting their unique structures and functions in the body.
Digestive System
Explaining the digestive system process starting from the mouth to the small intestine, including enzyme secretion, breakdown of food components, and nutrient absorption.
Photosynthesis in Plants
Detailing the process of photosynthesis in plant cells, explaining how chloroplasts convert sunlight, water, and carbon dioxide into glucose for plant nutrition.
Respiratory System
Exploring the respiratory system, including the nasal cavities, bronchioles, alveoli, and the exchange of oxygen and carbon dioxide in the lungs.
Endocrine System
Discussing the endocrine system's role in hormone production and regulation of body functions, focusing on organs like the pancreas, kidneys, and adrenal glands.
Kidney Function
Detailing the structure and function of the kidneys, explaining the process of blood filtration, reabsorption, and urine production in the nephrons.
DNA and Protein Synthesis
Explaining the structure of DNA, nucleic acids, and the process of protein synthesis through transcription and translation in cells.
Food Web and Energy Transfer
