Cells: The Building Blocks of Life and Their Functions

The video explains that all living things are made of cells, which are the basic building blocks of life. It covers the structure and function of plant and animal cells, including the cell membrane, cell wall, and various organelles like the nucleus, vacuole, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, and chloroplasts. The video highlights the importance of cells in supporting life and their role in processes like cellular respiration and photosynthesis.
