Bio principles Exam 2 – Brooks Latest Update Graded A+ Cytology the study of cells Robert Hooke - observed cork could float - discovered a honeycomb-like structure in a cork slice using a primitive compound microscope - only saw cell walls as this was dead tissue - coined the term "cell" for these individual compartments he saw Two types of microscopes: 1. Light Microscope 2. Electron Microscope Light Microscope - light is focused on specimen by a glass condenser lens -...

Homeostasis When organisms maintain a stable internal environment even when external conditions change Metabolism Combination of chemical reactions taking place within an organism Stimulus A signal to which an organism responds Biosphere Means "living planet" Robert Hooke Scientist who looked at cork through a microscope and gave the name to cells Light Microscope A type of microscope Can magnify 1000x Not as strong as other microscopes Uses light Scanning Electron Microscope A typ...

Bio principles unit 2 brooks questions and answers graded A+ all organisms are made of cells and come from cells Cell theory When the cell size (INCREASES or DECREASES), the membrane gets smaller compared to cell volume. increases the study of cells Cytology "how can cork float" Took sections, looked under microscope and found that they had tiny chambers (aka cells) Robert Hooke Part of electromagnetic spectrum via sun, delivering energy that can be recorded as waveleng...
