OBJECTIVES: 8.L.5.1. -TSWU that cells carry on the many functions needed to support life including cell respiration, photosynthesis, protein synthesis, mitosis, and meiosis. . 5.10C – describe the differences between complete and incomplete metamorphosis of insects. Vocabulary. Cycle-. . A . series . of . repeating events that usually . lead back to . a . starting point.. Compare the life cycles of different kinds of animals.. Vocabulary . Adult. -the stage of an animal’s life cycle when it reproduces. . Egg. -a structure containing food that young animals need in order to grow. . Before we start genetics, let's review the process of what makes us all look different compared to our siblings, family, and classmates!. Sexual Reproduction. Sexual reproduction creates genetic variability. That is why we all look different and you look different from your siblings! . Variations on a Theme. Living organisms are distinguished by their ability to reproduce their own kind. Heredity . is the transmission of traits from one generation to the next. Variation . is demonstrated by the differences in appearance that offspring show from parents and siblings. Life Cycles. Overview: Variations on a Theme. Living organisms are distinguished by their ability to reproduce their own kind. Genetics . is the scientific study of heredity and variation. Heredity . Some of the chemical building blocks of life, called . macronutrients. , are required by organisms in large quantities. Water . –. Carbon. Hydrogen . –. Oxygen. Nitrogen . –. Phosphorous. Copyright © 2002 Pearson Education, Inc., publishing as Benjamin Cummings. Cell Cycle. 3. A . life cycle. of an organism is the generation-to-generation sequence of stages in its reproductive history.. 6.1 Chromosomes and Meiosis. Cells can be divided into 2 major groups:. Somatic (body): most of body tissue and organs. Germ: found in reproductive organs, develop into gametes. Gametes are sex cells – ova (eggs) & spermatozoa (sperm). 1. MEIOSIS AND SEXUAL LIFE . CYCLES. Heredity. = Continuity of biological traits from one generation to the . next. Variation. = Inherited differences among individuals of the same . species. Genetics. 1 identify the stages of meiosis. Only diploid cells caages of meiosis in a diploid cell where 2N = 6Meiosis involves 2 consecutive cell divisions. Since the DNA is duplicated result is 4 haploid cel Lydia R. Leonardo, DrPH. Biology 133 Lecture. Second Half. Module 2:.  . Reproductive Organs and the Sexual Cycle.  .
