PPT-Chapter 01-Reproduction in Organisms

Std XII By Ms Madhusrabani Patro PGT Biology DAV Public School Berhampur Introduction The period from birth to natural death is known as life span It dont . Characteristics of Living Things. G. Grow and Develop. All living things grow and get larger during their life.. . Living things may also develop and change as they get older.. R. Reproduce. Organisms make other organisms similar to themselves.. Dept. Theoretical Biology. How to simplify biology. to . interpret effects of . stressors. Organisms are . complex …. Stressing organisms …. … only . adds to the complexity. Response to a toxic (and other) stress depends on. The . disadvantages and advantages of sexual . reproduction. CfE. . Advanced Higher Biology. Unit . 2: . Organisms and Evolution. SQA mandatory key information. Disadvantages of sexual reproduction – males unable to produce offspring, only half of each parent’s genome passed onto offspring. Benefits outweigh disadvantages due to increase in genetic variation in the population. . 1. Make a Venn Diagram. 2. Asexual Reproduction. Sexual Reproduction. Both. Types of reproduction in living organisms. Asexual Reproduction. Requires only one parent. Offspring have 100% the same chromosomes as the parent.. 1. Make a Venn Diagram. 2. Asexual Reproduction. Sexual Reproduction. Both. Types of reproduction in living organisms. Pass DNA from parent to offspring. Asexual Reproduction. Requires only one parent. Modern cell theory. Keep in mind that:. All living things are made up of one . or . more cells.. The . cell . is . the basic unit of life.. All cells come from preexisting cells. Just as cells reproduce as part of the Cell Cycle, living organisms reproduce as part of the life cycle.. Section 1 – the world of biology. Section 2 – themes in biology. Section 3 – the study of biology. Section 1 – the world of biology objectives. Relate the relevance of biology to a person’s daily life.. Sexual vs. Asexual Reproduction Compare the results of uniform or diverse offspring from sexual or asexual reproduction Uniform offspring Diverse offspring Sexual reproduction Asexual reproduction Sexual Reproduction 1. Asexual Reproduction. Requires only one parent. Offspring have 100% the same chromosomes as the parent.. In other words, the offspring are exact “clones” of the parent.. 2. Asexual Reproduction. Test Tomorrow!!!!!!!. Which of the following is an advantage of sexual reproduction over asexual reproduction?. I. Sexual reproduction is more rapid and less complicated.. II. Sexual reproduction results in more diversity.. Binary Fission. Bacteria reproduce by a process called binary fission. Binary fission: a copy of their single chromosome is produced and then the cell divides in half so that one half gets one chromosome and the other half gets the other chromosome. A . clone. is an identical genetic copy of its parent. Many organisms naturally form clones via asexual reproduction. Cloning is also used in agriculture and research to copy desired organisms, tissues and genes. Standards. GSE S7L1: Obtain, evaluate, and communicate information to investigate the diversity of living organisms and how they can be compared scientifically.. GSE 7L1b: Evaluate historical models of how organisms were classified based on physical characteristics how that led to the six-kingdom system (currently archaea, bacteria, protists, fungi, plants and animals). Unit 2: Organisms and Evolution. Advanced Higher Biology. Miss A Aitken. Costs and Benefits. Two forms of reproduction:. Sexual Reproduction. Asexual Reproduction. Why do both forms exist?. They must exist because neither one is perfect for all situations. If it was perfect, only one would exist..
