Unit 2. Chapters 9-16. Cell Processes 1. Cellular Respiration‚ Photosynthesis‚ Cell Cycle‚ Mitosis‚ Meiosis‚ & Genetics. Note A: All work must be hand-written‚ including charts & diagrams. Note B: each answer requires more than one sentence & use diagrams whenever possible; failure to use diagrams will result in less points. Chapter 9 Outline 1) Principles of Energy Conservation a) Cellular respiration and fermentation are catabolic(energy – yielding) pathways b) Cells must recycle the ATP

Introduction The Earth is home to various forms of life contributing to the endless biodiversity that we see in our daily lives. In environments around the world there are distinct correlations between the environment and adaptations acquired by the organisms that live there. It has been shown that these adaptations

Unit 3 Lecture Study Guide 1. List the 4 primary tissue types and give the general characteristics and functions of each one. Nerve Tissue: transmit nerve impulses; coordinates and regulates body activities‚ bind and support nerve tissue; carry on phagocytosis; connect neurons to blood vessels‚ changes shape from squamous to cuboidal Epithelial Tissue: covers all free body surfaces and lines organs‚ anchored to connective tissue by basement membrane‚ lacks blood vessels‚ can reproduce

Unit 2 Lecture Study Guide 1) What are the parts of an atom? Where are the subatomic particles found? Parts of an atom- divided into two basic regions: 1. the central nucleus (contains heavy particles) 2. the electron cloud (contains very light‚ moving particles) Subatomic particles: 1.Protons (found in the central nucleus) 2.neutrons (found in the central nucleus) 3.electrons (spin rapidly in a cloud around the central nucleus) 2) How does the Atomic Mass # differ from the Atomic

Compare and contrast mitosis and meiosis * Mitosis: cell divides only once and the result is exactly the same as the previous. It produces identical diploids * Meiosis: cell divides twice and it produces non-identical haploids. Synapses (pairing of homologous chromosomes) and Crossing over happen here 47. What is crossing over‚ why is it important

the fungus to form a network of cells called a mycelium. During the sexual phase‚ cell fusion results in the formation of a single-celled‚ diploid zygote encased in an ascus (plural‚ asci). Within the ascus‚ each single-celled zygote undergoes meiosis and gives rise to four haploid cells. These haploid cells then undergo a single round of mitotic division and give rise to a total of eight haploid ascospores with thick cell walls in each ascus. Many of these rod-shaped asci‚ each with eight
