Life Science and Biology Year in Review - Cells-Genetics-Evolution-Symbiosis-Biomes-Classification

Review the entire year of Life Science with this video and Biology Study Guide. The video is long so this guide will help. 0:00 Introduction full-year review Biology 0:12 Characteristics of Life 0:31 Organelles of the cell 4:06 Levels of organization 8:00 Cell movement 9:31 Mitosis 11:00 Body systems Integumentary 13;00 Muscular 17:00 Skeletal 18:00 Circulatory 20:00 Immunity 23:00 Excretory system 25:00 Nervous system 28:00 Respiratory system 31:00 Genetics 33:00 Selective breeding 36:00 Punnett square 39:00 Evolution 42:00 Natural selection 45:00 Fossils 47:00 Symbiotic relationships 50:00 Food Webs 53:00 Biomes desert 55:00 Tundra 57:00 Rainforest 1:00:03 Taiga 1:03:00 Deciduous forest 1:06:01 Grassland 1:12:03 Aquatic 1:09:05 6 kingdoms Life Science or Biology class. We began the year with the basic unit of life, the cell. In other words, the cell is considered the smallest thing that is alive. In order for something to be alive, it needs to have these 6 characteristics. All living things are made of cells Contain DNA Respond to stimuli Grow develop Reproduce Require energy The organelles of a cell work together to keep the cell alive. The major organelles of the cell covered are the nucleus, Endoplasmic reticulum, mitochondria, Golgi body, cell membrane, lysosomes, and ribosomes. Life also has levels of organization cells make tissues which make organs which make organ systems make organisms. The cell divides during cell division which includes mitosis Cell division begins during interphase when the cell makes copies of organelles and DNA Mitosis begins with prophase when chromosomes first appear During the year in Life Science or Biology class, we discuss how the body systems work together to keep the body alive. These systems include, Integumentary system Skeletal system Muscular system Digestive system Immunity lymphatic Circulatory Excretory Nervous Respiratory Genetics is the study of how traits are passed from one generation to the next. Topics covered, the following topics Genes and chromosomes and traits An allele Working out Punnett squares Selective breeding Evolution helps explain the variety of life. We also covered an ecology unit and studied, symbiotic relationships, food webs, and the major land biomes.
