The Fundamental Unit of Life- Notes

Introduction to Cell 

Robert Hooke observed many tiny, hollow, room-like structures in a thin slice of cork through a compound microscope and called them cells.

Organisms with single cell are called unicellular organisms.

Organisms with multiple cells are called multicellular organisms.

Prokaryotes do not have nuclear membranes and membrane bound organelles.

Eukaryotes have a membrane bound nucleus and organelles.  

Cell Structure 

The cell is the fundamental and structural unit of life.

The plasma membrane is selectively permeable as it allows the movement of some substances in and out of the cell.

The nucleus controls cell division and cell development.
