Cells of the six kingdoms
There are six kingdoms that classify life on Earth - Eubacteria, Archaebacteria, Protista, Fungi, Plantae, and Animalia. Eubacteria and Archaebacteria are prokaryotic and unicellular, while Protista, Fungi, Plantae, and Animalia are eukaryotic. Protista can be unicellular or multicellular, Fungi and Plantae are multicellular, and Animalia are always multicellular. The kingdoms differ in their cell structures, body forms, and modes of nutrition, which can include photosynthesis, chemosynthesis, heterotrophic nutrition like phagocytosis, or secretion and absorption of enzymes
Cells
This document summarizes the key differences between prokaryotic and eukaryotic cells, as well as the main organelles found within eukaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles. The main organelles described are the nucleus, mitochondria, chloroplasts, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, and cell walls.
Cell organelles
This document summarizes the key components of plant and animal cells. It describes the cell membrane as the outer boundary that protects the cell and controls what enters and leaves. It notes that plant cells also contain a cell wall made of cellulose that provides protection and support. The nucleus controls most cell activities and contains DNA. The cytoplasm and organelles like the endoplasmic reticulum, Golgi complex, mitochondria, vacuoles, lysosomes, and chloroplasts carry out specialized functions like protein production, packaging and transport of materials, energy production, storage, and waste digestion.

Cells2 091001182025-phpapp01
Cytology is the study of cells. Anton van Leeuwenhoek first observed cells using microscopy in the 1600s. Robert Hooke coined the term "cell" after observing plant cells in 1665. The cell theory, developed in the mid-1800s, states that all living things are made of cells, cells are the basic unit of structure and function, and new cells are produced from existing cells. Cells come in two main types - prokaryotes which lack nuclei and organelles, and eukaryotes which have nuclei and organelles. All cells share common structures like the cell membrane, cytoplasm, and in eukaryotes, the nucleus, but they also contain specialized structures called organelles that perform
Cell differences plant & animal
Plant cells are typically rectangular in shape with a large, permanent vacuole and cell wall made of cellulose. They contain plastids like chloroplasts and have fewer mitochondria than animal cells. Plant cells divide using a cell plate, while animal cells are spherical, have a small temporary vacuole, lack plastids and a cell wall, and divide using a furrow with centrosomes aiding the process.
Cell Organelles
This document provides information about the structures and organelles found within cells. It discusses the nucleus, which contains DNA and directs cell activities, the cell membrane that controls movement in and out of the cell, the cell wall that supports plant cells, and the cytoplasm where organelles are found.

Cells come in two main types - prokaryotic cells like bacteria that lack organelles and a nucleus, and eukaryotic cells like human cells that have internal membranes, organelles, and a nucleus. Eukaryotic cells contain organelles such as the nucleus, which holds DNA, and the endoplasmic reticulum, Golgi complex, and lysosomes, which are involved in protein transport and waste digestion.
Cell structure and micro-organisms
All living things are made up of cells, the basic unit of structure and function. Robert Hooke first observed cells in 1655 using a microscope to view cork. Cells contain various organelles that carry out essential functions - the cell membrane contains and protects the cell, the nucleus controls cell processes, mitochondria produce energy, and plant cells also have a cell wall and chloroplasts. While animal and plant cells share many organelles, plant cells have a cell wall and larger vacuoles. Microorganisms like bacteria can be single-celled, while large organisms have many specialized cells.
Cell Structure and Function
The document provides an overview of cell structure and function. It defines the cell and outlines the cell theory. The major components of plant cells are described, including organelles like the nucleus, chloroplasts, mitochondria, and cell membrane. It also discusses the cytoskeleton and movement of substances across the cell membrane through passive diffusion, facilitated transport, osmosis, and active transport processes like endocytosis and exocytosis. The overall purpose is to introduce learners to key aspects of cell biology.

Speciation
Speciation is the process by which new species form. It occurs when populations become isolated from each other and diverge to the point that they can no longer interbreed. Isolation can be geographic, such as when physical barriers separate populations, or reproductive, such as when changes prevent successful mating. Speciation rates may be gradual over millions of years or punctuated by rapid changes following events like natural disasters. The evolutionary history and relationships between species can be modeled in cladograms or phylogenetic trees.
Evolution of populations
This document discusses population genetics and microevolution. It explains that evolution occurs at the genetic level through heritable changes in DNA, arising from various sources of genetic variation within populations like mutation, recombination, and random mating. The key concepts of gene pool, allele frequencies, genetic equilibrium, and Hardy-Weinberg principle are introduced to illustrate how evolution can result from changes in the distribution of alleles in a population over generations under the influence of genetic drift or natural selection.
Patterns of heredity and human genetics
This document discusses several patterns of human genetics and heredity, including simple dominant and incomplete dominant inheritance. It provides examples of traits that follow each pattern, such as tongue rolling being a simple dominant trait and flower color in plants being an example of incomplete dominance. The document also covers codominance, polygenic inheritance, sex determination and sex-linked traits such as hemophilia. It explains how traits can be influenced by sex hormones in some cases.
Dna to chromosomes
The document discusses how eukaryotic cells package DNA into chromatin and chromosomes. DNA is found in the form of chromatin during interphase, which involves tightly coiling DNA around histone proteins to form nucleosomes. Nucleosomes are the basic unit of DNA packaging, allowing the 2 meters of DNA in human cells to fit inside the nucleus. Chromosomes only form when cells are preparing to divide and reproduce, allowing DNA to be passed from parent cells to daughter cells.
Species interactions comm ecology
This document summarizes the five major types of species interactions: predation, competition, parasitism, mutualism, and commensalism. It defines each interaction and provides examples. Predation involves one species consuming another for food, while competition occurs when two species require the same limited resources. Parasitism benefits one species at the expense of the other. Mutualism is a cooperative relationship that benefits both species, such as pollination. In commensalism, one species benefits while the other is not affected.
The biosphere
The document summarizes the key spheres that make up Earth's biosphere - the geosphere, hydrosphere, atmosphere, and anthrosphere. It then discusses Biosphere 2, an artificial closed ecosystem experiment in Arizona meant to study interactions within a biosphere. The experiment identified issues like too much CO2 and not enough O2 or food production. It also summarizes the major biogeochemical cycles of water, carbon, nitrogen, and phosphorus that are vital to life on Earth.
Ecological succession
Ecological succession is the gradual replacement of one community by another over time. It is initiated by disturbances that remove existing organisms or alter resources and habitat. There are two types of succession: primary succession occurs in areas without soil, while secondary succession occurs in areas with existing soil following a disturbance. In both cases, pioneer species are the first to colonize, and succession progresses gradually until an equilibrium climax community dominated by less tolerant species is reached if undisturbed.
Unique properties of water
Water is a polar molecule that is essential for life. Its polarity allows it to dissolve many other polar substances and act as a solvent for biological molecules and reactions in living cells and organisms. Water has unique physical properties, such as a high heat capacity and ability to form hydrogen bonds, that make it well-suited to regulate temperature and support life processes on Earth. The polarity and hydrogen bonding of water molecules also allow water to have high surface tension and influence many other physical phenomena.
Cells
Cells are the basic units of life. All living things are made of cells, and cells come only from other living cells. There are two main types of cells - prokaryotic cells which lack a nucleus and membrane-bound organelles, and eukaryotic cells which have a nucleus and membrane-bound organelles. The document goes on to describe the structures and functions of various cell organelles like the nucleus, mitochondria, chloroplasts, cell membrane, and others. It also compares the differences between plant and animal cells.
Introduction to ecology 2
This document provides an introduction to ecology, including definitions of key terms and concepts. It explains that ecology is the study of the relationships between organisms and their environments. It describes the different levels of ecological organization from the biosphere down to the individual organism. It also defines biomes as large geographical areas with similar climates and ecosystems, and lists some major biomes such as tundra, taiga, and tropical rainforest. Finally, it discusses adaptations as traits that enhance an organism's survival and are maintained by natural selection.
Characteristics of life
This document outlines the 8 characteristics of living organisms: 1) unique biochemistry, 2) organization and cells, 3) response to stimulus, 4) homeostasis, 5) metabolism, 6) growth and development, 7) reproduction, and 8) adaptation and evolution. Each characteristic is defined and an example is provided to illustrate the meaning. The document explains that all living things share fundamental biochemical similarities and that cells are the basic functional units of living things.
Hierarchy of biology additional notes
The document discusses several key topics in biology including cells, tissues, organisms, populations, communities, ecosystems, biomes, and the biosphere. It explains that cells are the basic structural and functional units of all life on Earth and can be either prokaryotic or eukaryotic. Tissues, populations, and communities are discussed in the context of multicellular organisms. Ecosystems are natural systems consisting of biotic and abiotic factors in an area, while biomes represent major communities with similar environmental conditions over large geographic areas. Finally, the biosphere encompasses all global ecosystems within the zones of air, land, and water where life exists.
Methods used by biologists
Biologists use several methods to study organisms including making inferences based on observations and prior knowledge, direct observation using the five senses to detect things in experiments and record events, and both qualitative observations using words, diagrams, pictures, colors, odors and sounds as well as quantitative observations involving numerical data through measurements, calculations and graphs which must include units when reporting raw or processed data.
Hierarchy of biology
This document outlines the levels of organization in biology from the subatomic to the biosphere, as well as the core concepts covered in biology. It begins with subatomic particles and atoms/ions, then moves up through compounds, nanosystems, cells, tissues, organs and organ systems, organisms, populations and communities, ecosystems, biomes and the biosphere. It also lists the five core ideas typically covered in biology: unity and diversity, structure and function, energy and regulation, interdependence, and science, technology and society.
Introduction to HBS: Unifying Themes
Introduction to the course of Human Body Systems (and how it relates to basic anatomy and physiology)
What is biology and Why study biology?
Biology is the study of living things, life processes, habitats, interactions, history and future of life. It examines all kingdoms including animals, plants, fungi, protists, eubacteria and archaebacteria. Studying biology is important because living things are interdependent and human existence relies on other organisms. Understanding biology has allowed humans to develop agriculture, solve medical problems, and be curious about their place in the world. Continued discovery will provide knowledge to improve lives and ensure a healthy future for our planet.
Antigens and antibodies
Antigens are substances that cause the immune system to produce antibodies. Antigens can be external, like bacteria or viruses, or internal, like bacterial toxins or damaged cells. Antibodies are proteins produced by the immune system in response to antigens. Each antibody targets a specific antigen. When an antibody binds to its matching antigen, it helps protect the body or tags antigens for destruction.
Body defenses against infection
The document summarizes the body's immune defenses against infection. It describes two main types of immunity: innate immunity, which provides nonspecific defenses like skin barriers and phagocytes; and acquired (adaptive) immunity, which develops after exposure and provides pathogen-specific responses using B cells, T cells, antibodies, and immunological memory. The immune system uses successive lines of defense, from physical barriers and phagocytes to inflammation and antibodies, to protect the body. Vaccines help produce active immunity by exposing the immune system to weakened or killed pathogens.
Lymphatic system notes
The lymphatic system defends against infection and disease by returning tissue fluid to the bloodstream. It consists of lymphatic capillaries that collect fluid from tissues, terminal ends that connect to lymphatic ducts, and lymphatic ducts that return the fluid to the venous system.
Enzymes for hbs
Enzymes are proteins that act as biological catalysts and are necessary for most chemical reactions in living cells. They help reactions occur by lowering their activation energy. Enzymes have a unique three-dimensional shape with active sites that allow them to specifically bind to substrates and rearrange the molecules involved in chemical steps. While they are not consumed in these reactions, enzymes increase the rates of reactions and can be reused, making them highly efficient biological catalysts.
