Cell Organelles and Their Functions

The video tutorial explains the structure and function of various cell organelles, including the cell membrane, cytoplasm, and nucleus. It covers the endoplasmic reticulum's role in material distribution and protein processing, the function of ribosomes in protein synthesis, and mitochondria's role in energy production. The Golgi apparatus is discussed in terms of secretion, while lysosomes are noted for their digestive functions. Centrosomes are highlighted for their role in cell division, and plastids, including chloroplasts, are explained in the context of photosynthesis.
