ASU Bio 181 Exam 1- Practice questions, Exam Questions and answers, Graded A+ The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: - -kidney A cell that is anchorage-dependent for growth will also exhibit contact inhibition. - -true In your own multicellular body, cells with different functions have different DNA. - -false, their DNA is identical but different gene expression The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. - -true The paramecium swims by way of using a flagella. - -false, they use cilia In order to examine cells which are smaller than can be detected by the human senses what needs to be used? - -tehcnology Compared to bacteria which of the cell types below are not responsible for finding food - -Lymphocyte Macrophage Fibroblast A cancer cell will be anchorage-dependent for growth and immortal. - -false, a cancer cell is anchorage-independent for growth and immortal A normal cell is anchorage-dependent for growth and mortal. - -true A cell that is itself an organism must have a minimum of four needs presented in lecture. List these four things. - -a cell needs to find food, shelter, reproduce, and mate. Also be able to escape predators. In your own multicellular body, different cells in your body have a division of labor between them - -true What limits the paramecium from acquiring more complex functions? - -the number of biomolecular machines it can contain within itself Write a few sentences that explain what limits an individual cell from becoming more complex. - -It has a limited number of biomolecular machines that a cell can contain and limits it from being more complex. It has to do everything for itself. Also has a certain number of parts with which to change its engineering, thereby changing its function.
