Course Overview

Acellus General Biology provides a basic introduction to biology, the study of life. A major focus of this course is the cell – its structure and function, cell transport and cellular energy, and how cells divide. Students will explore genetics and learn about DNA. Units on ecology and evolution are also included. Acellus General Biology is taught by Acellus Instructor Levi Goes. Acellus General Biology is A-G Approved through the University of California.

Scope and Sequence

Unit 1 – Ecology This unit discusses ecology and interdependence, the organization of the biosphere, producers, consumers, decomposition, the capturing of energy, the food web and food chain, energy versus nutrients, primary productivity, and symbiotic relationships. Also covered are competition, mutualism and commensalism, predation, camouflage and mimicry, parasitism, population growth, carrying capacity, what limits population growth, and ecological succession. Unit 2 – Cell Structure and Function This unit discusses cell organelles, the nucleus, mitochondria, ribosomes, cell theory, eukaryotes versus prokaryotes golgi apparatus – endoplasmic reticulum, vacuoles and lysosome, and chloroplast. Unit 3 – Cell Transport This unit discusses cell membranes, cell walls, strength of solutions, osmosis, diffusion, active versus passive transport, endo and exocytosis, and facilitated diffusion. Unit 4 – Cellular Energy This unit discusses how photosynthesis was discovered, the equation for photosynthesis and rates of photosynthesis. Also discussed are the equation for cellular respiration, ATP and ADP, chlorophyll, pigments, photosynthesis and cellular respiration. Unit 5 – Cell Division This unit covers mitosis, why cells divide, cancer, meiosis and crossing over, haploid and diploid, mitosis versus meiosis, asexual and sexual reproduction, the cell cycle, and cytokinesis. Unit 6 – Genetics This unit discusses the contributions of Gregor Mendel to the science of genetics. Also covered are characters and traits, genotypes and phenotypes, genes and alleles, homozygous and heterozygus, fertilization, probability, Mendel's F1 cross, the law of segregation, Mendel's F2 Generation, incomplete dominance, codominance, multiple alleles, and polygenic versus single gene traits. Unit 7 – DNA This unit discusses the history, shape, and structure of DNA, as well as nucleosomes, replication, transcription, RNA, genetic code, translation, and mutations. Unit 8 – Evolution This unit discusses the work of Charles Darwin, the galapagos, inherited variation and artificial selection, the evidence of evolution, natural selection, vestigial structures, allele frequencies, and changes in the population.
