Explain cell theory, the definition of a cell, and the different organelles found in cells along with their functions.
Understand the Problem
The question is presenting information about cell theory, the definition of a cell, different types of cells, cell parts (organelles), and their functions. This content appears to be for educational purposes, summarizing key concepts in cell biology.
Answer
Cell theory states organisms are made of cells, cells are the basic units of life, and all cells come from existing cells. Organelles like the nucleus and mitochondria have specific roles.
Cell theory states that all organisms are made of cells, cells are the basic unit of life, and all cells arise from existing cells. A cell is defined as the basic structural and functional unit. Key organelles include the nucleus, mitochondria, ribosomes, ER, Golgi apparatus, and lysosomes, each serving specific functions.

More Information
The cell theory was formally articulated in 1839 by Schleiden and Schwann and it remains one of the foundations of biology. Each organelle within a cell has unique functions, akin to organs in a body.
Tips
A common mistake is confusing the functions of different organelles or misunderstanding the scope of the cell theory—it's universal across all forms of life.
