Protists kingdom
Protists are a diverse group of eukaryotic organisms that are not classified as animals, plants, or fungi. They have simple cellular organization without specialized tissues or organs. Protists range from unicellular organisms like amoebas to multicellular forms like seaweed. Though diverse in appearance, protists are grouped together in the Kingdom Protista because they do not fit into other kingdoms. There are estimated to be between 60,000 to 200,000 protist species.
Six-kingdoms-of-life
This document defines and provides examples of different kingdoms of life: Archaebacteria, Eubacteria, Protists, Fungi, Plants, and Animals. It explains that Archaebacteria and Eubacteria are the oldest and most simple forms of life, often single-celled, found in extreme environments. Protists are also microscopic single-celled organisms that are distinct from plants, animals, bacteria, and fungi. Fungi include mushrooms and molds, some important to ecosystems while others can cause disease. Plants are generally multi-cellular producers that generate their own food. Animals, the largest kingdom, are multi-cellular consumers that require eating other organisms for energy and nutrition.
Protista
Protista are a kingdom of unicellular eukaryotic organisms that include protozoa, algae, and other types. They can be aquatic and found in moist environments. Protista have characteristics of both plants and animals, as they are eukaryotic but mostly unicellular. The kingdom is divided into protozoa, algae, and other groups like paramecium and euglena. Protozoa can be parasitic and kill other organisms for food, while algae include single-celled and multi-cellular photosynthetic organisms that come in various colors.
Binomial Classification
This document discusses the three kingdom and five kingdom classification systems of microorganisms. It describes Ernst Haeckel's original three kingdom system from 1866 which divided organisms into Protista, Plantae, and Animalia. It then outlines Robert Whittaker's five kingdom system from 1969 which is based on cell structure, body organization, nutrition mode, and nutrition source, dividing organisms into the kingdoms of Monera, Protista, Fungi, Plantae, and Animalia. Each kingdom is defined with examples of phyla contained within and characteristics around cell structure, nutrition, and reproduction.
Protozoa

1.general introduction to medical parasitology
Here are short notes on the life cycle of a parasite:
(a) Life cycle of parasite:
The life cycle of a parasite refers to the series of changes and stages it passes through from egg/cyst/spore to adult form. There are two main types of life cycles:
1. Direct life cycle: Requires only one host. Eggs/cysts are passed in feces and ingested by the same or another host, where they develop into adults.
2. Indirect life cycle: Requires two or more hosts. Eggs/cysts are passed and ingested by an intermediate host. Larvae develop and infect another definitive host, where they mature into adults. The adults reproduce
Parasitism
This document defines and describes different types of parasitism. It begins by defining parasitism as a relationship between species where one benefits at the expense of the other. It then describes 8 types of parasitism: obligate, facultative, ectoparasitism, endoparasitism, mesoparasitism, epiparasitism, brood parasitism, and social parasitism. Each type is defined and an example is provided, such as head lice for ectoparasitism and Plasmodium for endoparasitism. The document concludes by thanking the reader.

Science8_Protista.pptx
Protists are eukaryotic organisms that are neither plants, animals, nor fungi. They can be unicellular or multicellular and live in aquatic or moist environments. Protists have membrane-bound organelles and nuclei and can be autotrophic or heterotrophic. They reproduce asexually, though sexual reproduction occurs rarely under stress. Protists are classified into groups like protozoans, algae, and slime molds.
Introduction to non chordates
This document provides an introduction to non-chordates, also known as invertebrates. It discusses that invertebrates lack a backbone or spinal column and make up 95% of all animal species. Invertebrates are further divided into chordates and non-chordates based on the presence or absence of a notochord. Animals lacking a notochord are called non-chordates, while those also lacking a vertebral column are called invertebrates. The document then covers the 30 invertebrate phyla, their defining characteristics, examples of major and minor phyla, differences between lower and higher invertebrates, and general characteristics of invertebrates such as habitat, size,

Amazing Sperm Plants
Flowering plants first appeared around 135 million years ago and have since diversified greatly. They have flowers that attract pollinators like bees, helping the plants reproduce. There are over 500 ways to classify flowers based on their many variations from crossed genes between species. Angiosperms can be divided into two main classes - monocots and dicots - based on their seeds and seedling structure. Monocots have one seed and dicots have two. Angiosperms can also be classified as woody, herbaceous, annual, perennial, or biennial based on characteristics like their stem structure and lifespan.
Cnidarians
Cnidarians are a phylum of aquatic animals that include jellyfish, corals, sea anemones and hydroids. They live in oceans around the world, from the surface waters to the deep sea. Cnidarians have two life stages - a free-swimming medusa stage and a stationary polyp stage, where they are attached to a surface. Their life cycle often involves both a medusa and polyp form.
Stems
Stems perform several functions like producing leaves, branches, and flowers. They transport substances between roots and leaves and hold leaves up towards sunlight. Monocots have vascular bundles arranged in the stem, while dicots and gymnosperms have vascular bundles arranged in cylinders with xylem and phloem tissue. Primary growth occurs through cell division at the stem tip in all seed plants, resulting in increased length. Secondary growth occurs through thickness, with cork cambium forming the outer covering and vascular cambium between vascular tissues producing new layers of xylem wood.
Gretchen Harrigan
Fungi are living organisms that are more closely related to animals than plants. They absorb nutrients from decaying matter in the soil rather than producing their own food through photosynthesis. Fungi are made up of fine threads called hyphae that intertwine to form a tangled web-like structure called a mycelium. Hyphae may contain cross walls that divide them into separate cells. Fungi play an essential role in the environment by aiding plant root function and breaking down dead organic material.
Leaves, Roots, And Stems
Sponges are multicellular animals that live attached to surfaces in marine environments. They filter feed by drawing water through their bodies to absorb nutrients while releasing waste. Sponges can reproduce both sexually through internal fertilization or asexually. There are over 5,000 known sponge species. Sponges were some of the earliest forms of animal life on Earth.
This Is My Power Point
Leaves are the main organs for photosynthesis in plants. They are made up of a thin flattened blade connected by a petiole stalk to the stem. The blade is covered by an epidermis layer and vascular tissues which transport water and nutrients. Mesophyll tissue inside the leaf contains chloroplasts that perform photosynthesis, producing carbohydrates that move through phloem vessels to the rest of the plant. Sunlight is absorbed by palisade mesophyll cells at the top and travels through spongy mesophyll cells at the bottom. Stomata pores allow gases like oxygen and carbon dioxide to diffuse in and out for photosynthesis. Water lost through transpiration is replaced through xylem vessels in the vascular tissue

Archaebacteria differ from eubacteria in that they lack peptidoglycan and have distinct membrane lipids, and their DNA sequences are more similar to eukaryotes. Archaebacteria thrive in harsh environments like digestive tracts, salty lakes, and oxygen-depleted mud. Prokaryotes use flagella for movement and undergo cellular respiration for energy. They can also exchange genes between cells through conjugation. Prokaryotes reproduce through binary fission, doubling in size before dividing into two daughter cells.
Kyle Wood
1) Different types of algae, called protists, are described including euglenophytes, dinoflagellates, and chrysophytes.
2) Euglenophytes are plantlike protists that reproduce through binary fission and have two flagella but no cell wall.
3) Dinoflagellates can be photosynthetic or heterotrophic, reproduce through binary fission, and store DNA but not histones like other organisms.
Mammals
Mammals are classified into several groups based on how their young develop. Marsupials carry their young in pouches after they are born. Monotremes lay eggs that hatch outside the body. Placental mammals exchange nutrients between the mother and embryo through the placenta. There are many types of placental mammals including those that live on land or in water, fly, have hooves or trunks. Convergent evolution has led to similar structures developing in different mammals living in similar climates.
Fishes
This document discusses the characteristics, evolution, feeding, and respiration of fish. It notes that fish generally have paired fins, scales, and gills. Originally fish were armored and jawless, but in the Devonian Period fish evolved paired fins and jaws. Fish can feed in different ways depending on their environment, including herbivores, carnivores, parasites, filter feeders, and detritus feeders. Gas exchange occurs through gill filaments and blood circulates through fish in one loop.
Primates And Human Origins Powerpoint
The document discusses primates and human origins. It defines hominids and primates, noting that hominids evolved to walk upright and have opposable thumbs, while primates have binocular vision and well-developed brains and limbs. It outlines the two hypotheses for modern human evolution - the multi-regional model suggesting independent evolution in several places, and the out-of-Africa model where Homo sapiens first evolved in Africa from earlier species like Homo habilis, Homo ergaster, and Homo erectus. It also discusses Homo neanderthalensis and evidence that Homo sapiens lived alongside them around 50,000-40,000 years ago.
Viruses Final Presentation!
There are three main types of bryophytes: mosses, which commonly grow in moist areas; liverworts, which resemble flat leaves attached to the ground and get their name from resembling a liver; and hornworts, which are found in soil damp year-round. Bryophytes are non-vascular plants that are typically found in damp, moist environments like evergreen forests and go through a life cycle of growth, reproduction, and dispersal.

Viruses are particles that can only reproduce by infecting living cells and contain nucleic acid, protein, and sometimes lipids. They do not have fossils but may have impacted life's history. Viruses use capsids made of protein to enter host cells. Some viruses infect bacteria while others contain RNA as their genetic material or are made solely of protein. Viral infections can be lytic, causing the cell to burst, or lysogenic where the virus embeds its DNA into the host cell DNA. Many human diseases are caused by viruses such as polio, measles, AIDS, influenza, and rabies.
Amphibians
Amphibians are vertebrates that typically live both on land and in water. They evolved adaptations like stronger bones and limbs that allowed them to move on land while still having lungs and gills. There are three main groups of amphibians - salamanders, frogs and toads, and caecilians. Amphibians have defenses like poisonous skin secretions and camouflage to protect themselves from predators.

Ecology Of Fungi
Fungi are heterotrophs that obtain nutrients by breaking down and absorbing organic matter using digestive enzymes and thread-like mycelium. As decomposers, fungi recycle nutrients by breaking down dead organisms and waste. Some fungi are also parasites that can cause diseases in plants, animals, and humans. Fungi also form symbiotic relationships with photosynthetic organisms like lichens and plant roots through mycorrhizae.

Birds have wings and feathers that allow them to fly. They maintain a constant internal body temperature and have specialized features like bills and digestive systems that help them survive. There are many groups of birds including songbirds, raptors, and flightless birds. Birds play important ecological roles like seed dispersal and pest control. They have been around for over 150 million years.
Reptiles Sigrid Ryan
Reptiles are scaly animals that live in warm areas and eat plants or small animals. There are several types of reptiles including lizards, snakes, crocodilians, turtles, and tortoises. Reptiles are ectothermic, meaning they rely on external heat sources like sunlight to regulate their body temperature. While dinosaurs were the largest reptiles to ever live, modern reptiles have diversified to fill ecological niches through evolution from a common ancestor.
