Biology topic 1: cells and microscopy
Cells
Structures:
Ribsomes
Protein synthesis
Mitochondria
Release chemical energy required for chemical reations
ATP - adenosine triphosphate - where the chemical energy produced by the mitochondria is stored - protein
Cell wall
Protects cell -found in plants cells
Cellulose
makes up the walls of plant cells
Nucleus
tells the cell what to do - stores DNA
Cell membrane
Controls what enters and exits the cell - found in both
cytoplasm
supports and suspends organelles
Chloroplasts
Allow plants to capture the energy of the sun for photosynthesis.
Vacuole
help maintain water balance
Microscopy
Types of microscopes
Light microscope
Uses visible light and a system of lenses
Electron microscope
Uses electon beams instead of light
Uses of microscopes
Microscopes can be used to observe subjects at a cellular level, and allowing scientists to see the shape of a cell, its nucleus, mitochondria, and other organelles
Plant and animal cells are eukaryotes
Bacteria are prokaryotes
