Cell Organelles and Their Functions

The video tutorial provides an overview of cell structure, detailing the functions of various organelles such as the cell membrane, mitochondria, ribosomes, endoplasmic reticulum, lysosomes, and nucleus. It explains how these components work together to maintain cell function, including energy production, protein synthesis, and material transport. The video also highlights the unique features of plant cells, such as chloroplasts, vacuoles, and the cell wall, emphasizing their roles in photosynthesis and structural support.
