Cells

• Basic unit of life
• Building blocks of all living organisms
• Vary in size, shape, and function
• Classified into two main types: prokaryotic and eukaryotic
• Prokaryotic cells lack a nucleus and membrane-bound organelles
• Eukaryotic cells have a nucleus and membrane-bound organelles
• Organelles perform specific functions within the cell
• Examples of organelles include mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes
• Cells have a cell membrane that regulates the movement of substances in and out of the cell
• Cells can reproduce through cell division
• Cells carry out various metabolic processes, such as respiration, photosynthesis, and protein synthesis
• Specialized cells form tissues, which then form organs and organ systems in multicellular organisms
• Cells communicate with each other through chemical signals
• Some cells have the ability to differentiate and specialize into different cell types
• Cells play a crucial role in maintaining homeostasis within an organism.
