Chapter 9: Cellular Reproduction CELLULAR GROWTH -As the cell grows, its volume increases much more rapidly than the surface area. -The cell might have difficulty supplying nutrients and expelling enough waste products. TRANSPORT OF SUBSTANCES -Substances move by diffusion or by motor proteins. -Diffusion over large distances is slow and inefficient. -Small cells maintain more efficient transport systems. CELLULAR COMMUNICATIONS -The need for signling proteins to move throughout the cell also limits cell size. -Cell size affects the ability of the cell to communicate instructions for cellular functions. THE CELL CYCLE -Cell division prevents the cell from becoming too large -It also is the way the cell reproduces so that you grow and heal certain injuries

Chapter 12 The Cell Cycle Overview: The Key Roles of Cell Division Rudolf Virchow ? said ?where a cell exists, there must have been a preexisting cell, just as the animal arises only from an animal and the plant only from a plant?. Summarized by saying: ?omnis cellula e cellula? ? means every cell comes from a cell. Cell division ? plays several important roles in the life of an organism: Unicellular organism ? i.e. amoeba ? cell divides and forms duplicate, complete organisms. Larger scale ? cell vision can produce progeny (descendents) Enables sexually reproducing organisms to develop form a single cell (zygote) Can function in renwal or repair ? replacing cells that die (i.e. bone marrow, skin)

Campbell's Biology, 9e (Reece et al.) Chapter 12 The Cell Cycle In this chapter, 24 questions are new, and 12 have been altered to incorporate new material from the textbook. As in the other chapters, any questions that depend on figures or introductory scenarios have been placed at the end of the chapter rather than in concept sequence. Multiple-Choice Questions 1) The centromere is a region in which A) chromatids remain attached to one another until anaphase. B) metaphase chromosomes become aligned at the metaphase plate. C) chromosomes are grouped during telophase. D) the nucleus is located prior to mitosis. E) new spindle microtubules form at either end. Answer: A Topic: Concept 12.1 Skill: Knowledge/Comprehension

Chapter 12 The Cell Cycle Lecture Outline Overview: The Key Roles of Cell Division The ability of organisms to reproduce their kind is the one characteristic that best distinguishes living things from nonliving matter. The continuity of life is based on the reproduction of cells, or cell division. Cell division functions in reproduction, growth, and repair. The division of a unicellular organism reproduces an entire organism, increasing the population. Cell division on a larger scale can produce progeny for some multicellular organisms. This includes organisms that can grow by cuttings. Cell division enables a multicellular organism to develop from a single fertilized egg or zygote.

Chapter 13 Meiosis One of the characteristics of life is that organisms reproduce their own kind Exceptions to this rule only show up as tabloid rumors Offspring generally resemble their parents in some form Heredity-transfer of traits from parent to offspring But there is variation We will look at how chromosomes pass from parent to offspring Parents give offspring coded information in units called genes It is our link to our parents The genetic program is written in the language of DNA-4 bases It is symbolic DNA programs the cell to translate the information Ex: when we read the word apple, we see the fruit Cells do the same thing except in the form of a code that might mean freckles, blue eyes, brown hair

Campbell's Biology, 9e (Reece et al.) Chapter 13 Meiosis and Sexual Life Cycles New questions are mostly at higher skill levels in this chapter. The new questions represent newer material both in the chapter and in the area of biological research. All questions with accompanying art work or questions grouped together as sets have been organized at the end of the chapter. Multiple-Choice Questions 1) If a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants? A) Backtrack through her previous experiments to obtain another plant with the same traits.
