What features do a cell have?

Cells have several key features, including a plasma membrane that regulates the entry and exit of substances, cytoplasm where cellular processes occur, and genetic material (DNA) that contains the instructions for growth and reproduction. They may also contain organelles, such as mitochondria for energy production, ribosomes for protein synthesis, and in plant cells, chloroplasts for photosynthesis. Additionally, cells can vary in size, shape, and function depending on their type and role in an organism.
