Study Notes
Cell Structure and Function
- The jellylike substance inside the cell membrane is called cytoplasm.
- Lysosomes break down organelles that are no longer useful.
- Ribosomes make proteins using coded instructions from the nucleus.
- The cell membrane is semi-permeable phospholipid bilayer, allowing it to carry out its functions.
Cell Organelles
- Golgi body is responsible for packaging and processing proteins and lipids.
- Mitochondria are the site of cellular respiration, generating energy for the cell.
- Endoplasmic reticulum is a network of tubules and cisternae involved in protein synthesis, transport, and storage.
- Vacuole stores water, salts, and other substances.
- Nucleolus is responsible for producing ribosomes.
Cell Theory
- The cell theory states that all living things are composed of one or more cells and cell products, all living cells come from other living cells by cell division, and cells are the basic units of structure and function in an organism.
- Microscopes were essential for the development of the cell theory.
Spontaneous Generation
- Spontaneous generation is the discredited theory that life can arise from non-living matter.
- Louis Pasteur conclusively disproved the theory of spontaneous generation with his famous swan-neck flask experiment.
- John Needham and Lazzaro Spallanzani conducted experiments to test the idea of spontaneous generation.
Cellular Processes
- Nutrition is the process by which cells obtain food molecules to support their activities.
- Digestion is the process by which food particles are broken down into smaller units.
- Absorption is the process by which cells absorb water, minerals, and other materials.
- Biosynthesis is the process by which cells organize complex chemicals from simple building units.
- Excretion is the process by which cells eliminate waste products.
- Egestion is the process by which cells eliminate insoluble particles.
- Secretion is the process by which cells expel synthesized substances.
- Movement is the process by which cells respond to external stimuli.
- Irritability is the process by which cells respond to changes in their environment.
- Respiration is the process by which cells break down food molecules to generate energy.
- Reproduction is the process by which cells replicate their DNA and increase in number.
