LAB #1 Key De Anza Bio 10 DL Winter 2011 1) The compound scope contains 2 sets of lenses – the ocular lenses and the objective lenses. 2) This question was not graded – please ignore. 3) The ocular lenses are the eye pieces at the top of the scope with 10x magnification. 4) If there’s 10x already in the ocular lens, and you need to get to 200x, the objective that you would need must be a 20x objective 5) Eukaryotic organisms have a membrane-bound nucleus, whereas prokaryotes do not. 6) The fine focusing knob is used under high power magnification 7) A cover slip is the last thing added to make a wet mount. 8) Only a plant cell has a central vacuole, chloroplasts, and a cell wall. Animal and plant cells are alike in that they have several common organelles, including nucleus, mitochondria, endoplasmic reticulum, cell membrane, golgi apparatus, etc… 1) Nucleus – contains the DNA that guides protein production. Acts as the cell’s control center Mitochondria – Transforms energy in the food we eat to the chemical energy of ATP via

Unformatted text preview: cellular respiration Chloroplast – Transforms the energy of sunlight into chemical energy stored in sugar via photosynthesis Cell membrane – acts as the cell’s barrier, regulating passage of material in and out of the cell Cell wall – A more rigid structural barrier, protecting plant cells and helping plant’s to maintain rigid 3-D structures Cell vacuole – A large membrane-bound sac for storing water, sugar, etc… in a plant cell Endoplasmic reticulum – a network of membrane bound channels where proteins are produced from amino acids according to the instructions of a cell’s DNA Golgi apparatus – a series of flattened membrane-bound pouches to receive, sort, modify, and ship proteins to various area of the cell/body Ribosome – the workbench on which proteins are actually constructed from amino acids within the endoplasmic reticulum 2) Chloroplasts, Cell wall, and Cell vacuole are found only in plants....
