Microscopes, cells, genetics

• Light microscopes can magnify up to 1000x using visible light and up to 2000x using near-ultraviolet or near-infrared light.
• Electron microscope uses electrons instead of photons as the source of illumination
• Light microscopy uses visible light or light in the near ultraviolet or near infrared ranges to produce magnified images of samples.
• 'Mitochondria are responsible for producing energy through respiration.
• 'The cytoplasm contains organelles that carry out specific functions within the cell.'
• The nucleus is where DNA is stored and controls cellular activities.
• Chloroplasts contain chlorophyll and are involved in photosynthesis.
• Different types of lenses are used for different purposes, such as low power objectives for general viewing and high power objectives for detailed observation.
• Ribosomes synthesize proteins from amino acids.
• 'Ribosomes are involved in protein synthesis.'
• 'Vacuoles store water and other substances such as pigments and waste products.'
• Chromosomes contain genetic information and determine an individual's characteristics.
• Chromosomes contain genetic information and determine an individual's characteristics.
• A condenser lens focuses light onto the specimen being viewed.
• Cilia and flagella are hair-like structures that move substances or propel the cell itself.
• Mitochondria produce energy through respiration.
• Lysosomes break down and recycle worn-out parts of the cell.
• Cell membranes regulate what enters and exits the cell.
• Cytoplasm - jelly-like substance that fills most of the cell
• Mitochondria generate energy through respiration.
• The objective lenses magnify the image produced by the condenser lens.
• An eyepiece is used to view the enlarged image created by the objective lenses.
• Light passes through the specimen and is focused on the objective lens.
• A microscope has two main components: an illumination system (condenser) and an optical system (objective lenses).
• The stage holds the slide with the specimen being observed.
