What are the keys points of cell?

Cells are the basic structural and functional units of life, serving as the building blocks for all living organisms. Key points about cells include their classification into prokaryotic (without a nucleus, e.g., bacteria) and eukaryotic (with a nucleus, e.g., plants and animals) types. Cells perform essential functions such as metabolism, energy production, and replication, and they contain organelles that carry out specific tasks. Additionally, the cell membrane regulates the movement of substances in and out, maintaining homeostasis.
