1/Nastic Movement: "Nastic movements are non-directional responses to stimuli (e.g. temperature‚ humidity‚ light irradiance). The movement can be due to changes in turgor or changes in growth. Nastic movements differ from tropic movements in that the direction of tropic responses depends on the direction of the stimulus‚ whereas the direction of nastic movements is independent of the stimulus. The rate or frequency of these responses increases as intensity of the stimulus increases. An example of

Exercise 13 MITOSIS: REPLICATION OF EUKARYOTIC CELLS ANSWERS TO QUESTIONS 1. a. Mitosis and cytokinesis are often referred to collectively as "cellular division." Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided. b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and
