Protists are eukaryotic organisms that are more closely related to animals, plants and fungi than bacteria. They can be unicellular or multicellular without specialized tissues. Protists have a variety of means of locomotion including cilia, flagella and pseudopodia. They are found in aquatic ecosystems worldwide and some are pathogens of plants and animals. Protists exhibit both sexual and asexual reproduction and have been present on Earth since the Precambrian era.

Protozoa
Protozoans are unicellular eukaryotes that lack cell walls and motility is provided by cilia, flagella, or pseudopodia. They ingest food and can reproduce asexually through binary fission or budding or sexually through conjugation or gamete fusion. Plasmodium, a protozoan parasite, causes the disease malaria in humans. It has a complex life cycle alternating between mosquito and human hosts. In humans it evades the immune system by hiding in the liver and red blood cells, where it consumes hemoglobin and reproduces asexually.

They are eukaryotic with a nucleus and organelles, rely on their environment for nutrition, and do not have chlorophyll. Protozoa include flagellates, ciliates, and amoebae that move using flagella, cilia, or pseudopods respectively. As components of micro and meiofauna, protozoa are an important food source and play a role in transferring production between trophic levels as both herbivores and consumers. Examples of protozoa discussed include the amoeba, trypanosoma, plasmodium, paramecium, and
Protists
Protists can reproduce sexually through alteration of generations or asexually through mitosis. They are found in fresh water, salt water, and damp soil. Protists exhibit both eukaryotic and unicellular characteristics and can be autotrophic or heterotrophic. There are three major phyla of protists: protozoa, algae, and slime molds. Protozoa include amoebas and paramecium that move using pseudopodia or cilia and can be free living or parasitic.
Characteristics of protozoa
Protozoa are single-celled eukaryotic organisms that carry out all life activities within a single plasma membrane. They exhibit diverse shapes and sizes, ranging from flagellated Euglena and Paramecium to amoeboid Amoeba. Many protozoa are symbiotic or pathogenic to plants and animals, including humans, with some causing diseases like giardiasis. They display a wide range of symmetries, forms of locomotion, and means of nutrition, including autotrophy, heterotrophy, and saprozoism.

Unit 20 Protists And Fungi
The kingdom Protista is extremely diverse and contains eukaryotic organisms that are not classified as animals, plants, or fungi. Protists can be animal-like, plantlike, or funguslike. Animal-like protists are often single-celled heterotrophs that feed on other organisms, while plantlike protists, like algae, conduct photosynthesis. Funguslike protists decompose dead organic matter. Protists play important roles in ecosystems and some can cause serious diseases.
Protists
Protists are a diverse group of eukaryotic organisms that include protozoa, algae, and fungus-like protists. They can be unicellular or multicellular, microscopic or large, and obtain energy through photosynthesis or consuming other organisms or organic matter. Major groups of protists include protozoa such as amoebas, flagellates, ciliates, and sporozoans; algae which perform photosynthesis; and fungus-like protists such as slime molds, water molds, and downy mildews. Protists play important roles in ecosystems as producers, decomposers, and causes of diseases.
Lorinas protists
Protists are unicellular eukaryotic organisms that can be animal-like, plant-like, or fungus-like. They are classified into kingdoms based on these characteristics. Protists include protozoa such as amoebas and paramecium, algae, water molds, and other microorganisms. They serve important ecological functions and some can cause disease.
Biological classification
The document summarizes R.H. Whittaker's five kingdom classification system from 1969. It describes the key characteristics of each kingdom - Monera, Protista, Fungi, Plantae, and Animalia. Monera contains prokaryotic organisms like bacteria and archaea. Protista contains unicellular eukaryotes. Fungi are heterotrophic organisms that absorb nutrients. Plantae contains photosynthetic eukaryotes. Animalia are multicellular heterotrophs that ingest food. The classification system aimed to group organisms based on cell structure, nutrition, and evolutionary relationships.

BIOLOGY PPT KINGDOM PROTISTA By Adithya.pptx
This document discusses kingdom Protista. Protists are eukaryotic, primarily single-celled organisms that were traditionally grouped together. They include algae, protozoa, water molds, and slime molds. Protists reproduce both asexually through binary fission, budding, spore formation, and multiple fission, and sexually through the fusion of gametes. They play important ecological roles as primary producers, decomposers, and prey for other organisms, and some species have economic significance through food production, biofuel potential, and industrial uses.

Physical science final exam review
This document provides a review for a Physical Science final exam, outlining 9 competencies covered on the exam. It includes 75 multiple choice and short answer questions testing understanding of concepts in motion, waves, electricity, thermodynamics, atomic structure, nuclear processes, bonding, and acids/bases. Sample questions assess knowledge of the scientific method, graphing, Newton's laws, energy transformations, electromagnetic radiation, the periodic table, nuclear reactions, and chemical equations.
Newton
This document provides 42 multi-part physics problems involving Newton's laws of motion. The problems cover concepts such as force, mass, acceleration, weight, and their relationships. Some sample answers are provided. The problems involve calculating unknown values like force, mass, or acceleration given information about real-world scenarios involving objects in motion or at rest under the influence of various forces.
Waves
1. This document discusses different types of waves including transverse, longitudinal, and electromagnetic waves. It defines key wave properties such as amplitude, wavelength, frequency, period, and wave speed.
2. Frequency is defined as the number of vibrations per second, measured in Hertz (Hz). Period is the time for one full vibration. Frequency and period are inversely related.
3. Examples are provided to demonstrate calculating wave properties like frequency, period, wavelength, and wave speed from information given about the wave.
Electric power
This document discusses electrical power and energy. It explains that power is calculated as current multiplied by voltage, and is measured in watts. It asks the reader to calculate the power needed to operate a clock radio drawing 0.05 amps from a household circuit. The document also explains that electrical energy is provided by power companies and sold to homeowners in units of kilowatt-hours, which is 1000 watts delivered for one hour. It provides an example of calculating the electrical energy used and cost for a 1200W toaster oven used for 15 minutes.
Ac dc and circuits
This document explains the differences between alternating current (AC) and direct current (DC). It defines AC as an electric current that periodically reverses direction and changes its magnitude continuously with time in contrast to DC, which flows in one direction. The document also outlines the key characteristics of series and parallel electric circuits. Series circuits have the same current flowing through all elements and the total voltage is divided among the elements. Parallel circuits have the same voltage across each element and the total current is the sum of the currents in the individual branches. The document concludes by noting that fuses are used to prevent circuit overloading by melting and breaking the circuit if too much current passes through.

This document covers acids and bases, including definitions, properties, examples and the pH scale. It also discusses acid rain, its effects and causes. For radioactivity, it defines different types and compares the strong force to the electric force in alpha and beta equations. It explains transmutation, half-life, fission and chain reactions. Additionally, it outlines nuclear power plants, how they create electricity from fission, reasons for past meltdowns and pros and cons of nuclear power. Finally, it addresses the big bang theory, evidence supporting it, the potential end of the universe, star formation, star types and life cycles.
Chemical reactions
This document discusses chemical equations and reactions. It explains that chemical equations are used to represent chemical reactions, and that they consist of reactants on the left side of the arrow yielding products on the right. It also describes how to balance chemical equations by adjusting coefficients so that the same number of each type of atom is on both sides of the equation. Balancing chemical equations ensures conservation of mass during chemical reactions.
Naming and writing compounds and molecules
This document provides instructions for writing formulas and naming ionic compounds, covalent molecules, and polyatomic ions. It explains that for ionic compounds, you write the symbols of the ions and use the crossover method to determine subscripts before naming the compound by writing the cation name followed by the anion name with "ide." For covalent molecules, Greek prefixes indicate subscripts and the name is written by specifying each element followed by the number of atoms. Polyatomic ions are also named and included in ionic compounds by looking up their formula and charge. Examples and practice problems are provided to demonstrate the process.
Bonding practice
1) The document provides instructions for drawing Lewis structures to show ionic and covalent bonding between various elements. Students are asked to draw Lewis structures for pairs of elements, and indicate electron transfers or sharing to write chemical formulas. 2) For ionic bonds, students should draw Lewis structures, arrows to show electron transfer, charges for each ion, and chemical formulas. 3) For covalent bonds, the instructions are to draw Lewis structures, circles around shared electrons, bond structures, and chemical formulas.
Atomic spectrum
The document discusses atomic spectra and the Bohr model. It explains that atoms can absorb and emit light at specific frequencies, and this atomic spectrum acts as a fingerprint that can be used to identify elements. The Bohr model describes electrons occupying different energy shells around the nucleus, and electrons absorbing and emitting energy by jumping between shells and releasing light. The document also briefly mentions flame tests and spectroscopes as methods to observe atomic spectra.
Rutherford
Ernest Rutherford (1871-1937) was a notable British physicist and chemist who made seminal contributions to the development of the modern atomic model. Through his gold foil experiment in 1911, Rutherford was able to formulate the Rutherford model of the atom, which established that atoms have a small, positively charged nucleus surrounded by low-mass electrons. For this breakthrough discovery, Rutherford received numerous honors including the Nobel Prize in Chemistry in 1908. His work fundamentally changed scientific understanding of atomic structure.
Meinter
Lise Meitner was an Austrian/German physicist born in 1878 who made significant contributions to nuclear physics. She received her doctorate in 1905 as the second woman to earn a PhD from the University of Vienna. In 1938, Meitner, Otto Hahn, and Fritz Strassmann discovered nuclear fission when bombarding uranium with neutrons. This splitting of uranium atoms led to additional neutrons and the potential for an explosive chain reaction. Sadly, her discovery was later used in 1945 for the atomic bomb dropped on Hiroshima. Meitner received several honors for her work, including the Max Planck medal in 1949.
Gell mann
Murray Gell-Mann was born in 1929 and is still living. He graduated valedictorian from Columbia Grammar School and attended Yale University at age 15. Gell-Mann won the 1969 Nobel Prize in Physics. In 1964, he discovered the quark, which makes up protons and neutrons in the nucleus. Quarks have never been isolated due to their small size of 10-15 mm. Gell-Mann is also interested in activities like bird watching and collecting antiques.
Democritus
Democritus was a Greek philosopher born around 460-457 BC in Abdera, Thrace. He developed the first atomic theory, proposing that all matter is made up of indivisible atoms moving through empty space. Democritus believed that atoms were the fundamental building blocks of the natural world and that their behavior determined natural phenomena. He and his mentor Leucippus are considered the founders of atomic theory. Democritus was highly respected in his lifetime for making discoveries and predictions that were later proven true.

Protists
- 1. Protists Molly, Annie, Shannon, Gabrielle, Emily
- 2. Phylogenetic Tree for Kingdoms I <3 Protists
- 3. What does this mean ? As you can see, Protists are under the Eukaryotes section on the right of that graph. That means they are more closely related to animals, plants, and fungi then they are to chloroplast and mitochondria. OH I get it
- 4. DISTINCTIONS from other kingdoms ● Protists have simple organization. Either they are unicellular, or they're multicellular without specialized tissues. ● Protists, as previously stated, are eukaryotes. Bacteria, however, is prokaryotic. ● They have a true nucleus ● Fascinating!
- 5. What makes a protist a protist? Protists are... ● Eukaryotic organisms ● Live in almost any area with liquid water ● Are autotrophs or organotrophs (by absorption or ingestion) ● Can reproduce sexually (gametic) or asexually (binary fission) ● Can be pathogens for animals or plants; e.g. malaria Protists rock!! ● Produce oxygen
- 6. How do they move? ● Cilia- microscopic "hairs" that extend from the protist that act in unison to move the organism. ● Flagella- A long appendage (like a whip) that moves the organism. It can be a single or double appendage. ● Pseudopodia- A temporary projection of the cytoplasm (amoebas often move this way) Soooo locomotive
- 7. Ecology ● Found in ponds, on trees, or other natural aquatic ecosystems ● Fossilized protists have been found from the Precambrian era (1.9 bya) ● Some symbiotic protists live with fungi or other plants WOWZA
- 9. WOAH look at all those little guys!
- 10. Lets review!! WOO Recap: Protist move using cilia, flagella, pseudopodia. Found in habitats where water is also found. Some are single cellular, some are multicellular. Some are autotrophs some are heterotrophs. Protists eat other protozoa, amoeba and algae.
