Study Notes
- Cells were discovered in 1665 by Robert Hooke in cork slices.
- Cells are the basic units of life and make up all living things.
- The Cell Theory states that all living things are made of cells, the cell is the basic unit of structure and function, and cells only come from pre-existing cells.
- Organisms can be unicellular or multicellular.
- Prokaryotes are small and simple cells, while eukaryotes are large and complex cells found in animals and plants.
- Plant cells have a cell wall, cell membrane, cytoplasm, nucleus, ribosomes, endoplasmic reticulum, Golgi body, mitochondria, lysosome, vacuoles, and chloroplasts.
- The cell wall provides strength and support to the plant and is mainly made up of cellulose and lignin.
- Cellulose is used for making paper and can be converted into cellulosic ethanol, a biofuel.
- Some animals can digest cellulose with the help of bacteria in their stomachs, but humans cannot.
- Cellulose is important for dietary fiber and keeping waste moving through the digestive system.
