Understanding Cell Structure, Genetics, and Ecosystems: A Comprehensive Overview

This resource provides an in-depth exploration of cell structures, including the cell membrane, mitochondria, nucleus, and organelles involved in transport, such as the rough and smooth endoplasmic reticulum. It delves into key genetic concepts like DNA, genes, chromosomes, and the principles of inheritance highlighted by Mendel's work with pea plants. Additionally, explore environmental interactions through habitats, populations, and ecosystems, discussing factors that influence population size and natural selection. Understand complex relationships such as symbiosis and succession processes.

Presentation Transcript

  1. Test Review

  2. Parts of the Cell • Cell Membrane • Mitochondria • Nucleus • Lysozome • Rough Endoplasmic Reticulum • Smooth Endoplasmic Reticulum • Ribosomes • Microtubules

  3. Transport Into/Out of Cell • Active Transport: takes energy • Endocytosis/Exocytosis • Diffusion/Osmosis

  4. Cell Division • PMAT (prophase, metaphase, anaphase, telophase) • Asexual reproduction vs. Sexual reproduction • Mitosis vs. Meiosis • Sex cells (half cells)

  5. DNA • Adenine (A), Thymine (T), Cytosine (C), Guanine (G) • Genes: the section on DNA that makes a specific protein • Chromosome: 23 pairs of them in each human (23 from mom, 23 from dad) made up of millions of genes each • Mutation: any permanent change in a gene or chromosome

  6. Genetics • Mendel and his pea plants • Alleles (B or b): different forms of genes for different traits (brown hair or blond hair) • Dominant and recessive factors • Punnett Squares • Homozygous (BB or bb) • Heterozygous (Bb) • Genotype: Bb Phenotype: Brown hair

  7. Genetics • Incomplete Dominance: two alleles are dominant to each other (red and white making pink) • Multiple Alleles: more than two possible alleles (blood type has three possible alleles (A, B, and O) • Polygenic Inheritance: many different genes work together for one phenotype (finger prints or eye color)

  8. Habitat • Organism: one individual member of a species • Habitat: where an organism lives • Abiotic/Biotic • Species: a group of organisms that can mate and produce offspring that can mate • Populations: all members of one species living in the same area • Communities: all the populations living in a given area • Ecosystems: all abiotic and biotic factors in a given area

  9. Populations Change in Size • Birth rate and death rate • Immigration and emigration • Population Density • Limiting Factors

  10. Natural Selection • Adaptations • Niche • Competition • Predator/prey • Symbiosis: mutualism, parasitism, and comensalism

  11. Succession • Primary succession • Secondary succession
