Question details

Multiple-choice/True-false/Matching 1. The water content of a typical human cell is around 65-70%. Using your knowledge of cellular anatomy and physiology, what is the normal percentage of carbohydrates in a typical human cell? a) 0% b) 1-5% c)30-40% d) 50-60% 2. Humans, plants, animals, fungi,protists and bacteria are all composed of one or more cell. Viruses (which cause diseases such as AIDS, measles, viral pneumonia and chicken pox) are: a) composed of cells b) not composed of cells 3. All cells currently on earth came from preexisting cells: a) true b) false 4. Oxygen moves from the blood into nearby body tissues. The process that drives this movement is called a) active transport b) osmosis c) diffusion d) mitosis e) phagocytosis 5. What is the order of the following, from smallest to largest: 1. an amino acid molecule, 2. a human liver cell, 3. a hydrogen atom, 4. a cell nucleus 5. a carbon dioxide molecule д) 1, 2, 3, 4,5 b) 3, 5, 1, 4,2 c)1,5, 3, 4, 2 d)3,4,5, 1,2 e)5, 1, 3, 2,4 6. Division of a cells nucleus during somatic cell division is known as mitosis, while division of the cells cytoplasm is known as: a) telophase b) meiosis c) interphase d) cytokinesis e) S-phase 7. If your microscope had a 15x ocular lens, what would be the total magnification when using our scanning objective lenses? a) 4x b) 10x c)40x d) 60x e) 100x 8. The phase between cell divisions is known as a) interphase b) prophase c) anaphase d) metaphase e) phagocytosis 9. Parfocal means that: a) the microscope only uses one lens b) final focusing can only be done with the fine focus knob c) changing objective lenses will keep the specimen in focus or close to it d) the highest magnification is 1000x. Color Plates: Plate 6, The Generalized Cell: cell membrane (orange), rough ER (yellow), ribosomes (red), nuclear membrane (green), mitochondria (blue). Plate 7, Cell Division/Mitosis: cell membranes (orange), nuclear membranes (green), centrioles (yellow), all DNA (red). Microscope plates (on following pages), Label the following items with numbers as follows: ocular lenses (1), objective lenses (2), coarse focus knob (3), fine focus knob (4), stage clip (5), stage controls (6), camera lens housing (7). 18
