Cell Structure and Function Concepts

Cells are the basic units of life, with all cells having a membrane, cytoplasm, and DNA. They are categorized into eukaryotic and prokaryotic cells. Eukaryotic cells have organelles like the nucleus, while prokaryotic cells do not. Organelles perform specific functions, such as the nucleus controlling cell activities and mitochondria providing energy. Some cells have unique structures like cilia and flagella. Plant cells have chloroplasts for photosynthesis, while animal cells do not. The video concludes by summarizing the differences between cell types.
