2. What is the scientists involved?Robert Hooke, Matthias Schleiden, Theodor Schwann, Rudolf Virchow
3. What are cells and why are they important?Cells are tiny building blocks like LEGO bricks that make up all living things. They do all the jobs that keep us alive, such as giving us energy and letting us grow.
4. How big are cells and how do they stay inside?Cells are very small, usually between 0.1 and 100 micrometers wide. They are wrapped in a special skin called a plasma membrane that keeps the inside safe and lets the right stuff in and out.

Plasma Membrane: The selectively permeable outer boundary of a cell that regulates transport.
Eukaryotic Cell: A cell characterized by a membrane-bound nucleus and other organelles.
Prokaryotic Cell: A simpler cell type lacking a nucleus and membrane-bound organelles.
Homeostasis: The maintenance of a stable internal environment within a cell or organism.
