Study Notes
Basic Units of Life
- The basic structural and functional unit of life is the cell.
- Cells can be classified into two main types: prokaryotic and eukaryotic.
Types of Cells
- Prokaryotic cells lack a complex system of membrane-bound organelles and do not contain a true nucleus.
- Eukaryotic cells have a well-defined, true nucleus and contain numerous membrane-bound organelles.
Historical Discoveries
- The term 'cell' was coined by Robert Hooke in the 17th century.
- Anton van Leeuwenhoek is recognized for discovering bacteria and other microorganisms.
Human Genome Project
- The Human Genome Project aimed to sequence the approximately three billion bases of DNA found in every human cell.
- This monumental project took place from 1990 to 2003.
Biology and Origins of Life
- The literal meaning of biology is "the study of life."
- Life is believed to have first arisen about 3.5 to 4 billion years ago.
- The earliest organisms were prokaryotic and consisted mainly of simple cells.
