They have distinct cell nuclei and membrane-bound organelles which allow for compartmentalization and dedication of specific areas of the cell for specific functions.
Plays a very important role in the phylogeny of all eukaryotes.
They serve as the stem group for the fungi, plants, and animals.
Major groups within this kingdom include the algae, euglenoids, ciliates, protozoans and flagellates.
In five kingdom classification(scheme proposed by R. Whittaker in 1969), Protists make up a kingdom called “Protista”, composed of “Organisms which are unicellular or unicellular-colonial and which form no tissue.
Protists are the eukaryotes that are not members of the kingdom Plantae, Animalia or Fungi. Most Protists are unicellular, but few have hundreds or even thousands of cells.
Protists can be autotrophic or heterotrophic.
They move by cilia, flagella or pseudopodia.

Biology I Presentation
FUNGI
We will learn
General characteristics of fungi
Structure of fungi
Economic Importance
Pathogenicity
Brief intro of some fungi
THE SIX KINGDOMS
Fungi are placed in a separate kingdom called the kingdom fungi
OF FUNGI
CHARACTERISTICS
The Characteristics of Fungi
Fungi are NOT plants
Nonphotosynthetic
Eukaryotes
Nonmotile
Most are saprobes (live on dead organisms)
The Characteristics of Fungi
Absorptive heterotrophs (digest food first & then absorb it into their bodies
Release digestive enzymes to break down organic material or their host
Store food energy as glycogen
The Characteristics of Fungi
Important decomposers & recyclers of nutrients in the environment
Most are multicellular, except unicellular yeast
Lack true roots, stems or leaves
fungi as a decomposers
The Characteristics of Fungi
Cell walls are made of chitin (complex polysaccharide)
Body is called the Thallus
Grow as microscopic tubes or filaments called hyphae
The Characteristics of Fungi
Some fungi are internal or external parasites
A few fungi act like predators & capture prey like roundworms
The Characteristics of Fungi
Some are edible, while others are poisonous
The Characteristics of Fungi
Produce both sexual and asexual spores
Classified by their sexual reproductive structures
The Characteristics of Fungi
Grow best in warm, moist environments
Mycology is the study of fungi
Mycologists study fungi
A fungicide is a chemical used to kill fungi
The Characteristics of Fungi
Fungi include puffballs, yeasts, mushrooms, toadstools, rusts, smuts, ringworm, and molds
The antibiotic penicillin is made by the Penicillium mold
FUNGI SIZE
NON-REPRODUCTIVE
Vegetative Structures
Hyphae
Tubular shape
ONE continuous cell
Filled with cytoplasm & nuclei
Multinucleate
Hard cell wall of chitin also in insect exoskeletons
Hyphae
Stolons – horizontal hyphae that connect groups of hyphae to each other
Rhizoids – rootlike parts of hyphae that anchor the fungus
Hyphae
Cross-walls called SEPTA may form compartments
Septa have pores for movement of cytoplasm
Form network called mycelia that run through the thallus (body)
Absorptive Heterotroph
Fungi get carbon from organic sources
Tips of Hyphae release enzymes
Enzymatic breakdown of substrate
Products diffuse back into hyphae
Modifications of hyphae
Fungi may be classified based on cell division (with or without cytokinesis)
Aseptate or coenocytic (without septa)
Septate (with septa)
Modifications of hyphae
Hyphal growth
Hyphae grow from their tips
Mycelium is an extensive, feeding web of hyphae
Mycelia are the ecologically active bodies of fungi
ASEXUAL & SEXUAL SPORES
REPRODUCTIVE STRUCTURES
REPRODUCTION
Most fungi reproduce Asexually and Sexually by spores
ASEXUAL reproduction is most common method & produces genetically identical organisms
Fungi reproduce SEXUALLY when conditions are poor & nutrients
Protozoa (also protozoan, plural protozoans) is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2. CHARACTERISTICS OF PROTISTS
Simplest eukaryotes
Ernest Haeckel coined the term protista in 1886
mostly unicellular, some are multicellular
can be heterotrophic or autotrophic
microscopic or macroscopic
most live in water (though some live in moist soil or
even the human body)
ALL are eukaryotic (have a nucleus)
A protist is any organism that is not a plant, animal
or fungus.
3. Plantlike Protists
The algae, euglena, and dinoflagellates are
representatives of the plantlike protists.
Live in the aquatic environment (fresh and
salt water).
ALGAE
Algae is multicellular or unicellular, but the
single celled type can’t be seen without a
microscope.
Thrive in aquatic environment
They mostly use photosynthesis, but some
eat other protists or absorb nutrients for
food
Described as thallus body.
They are known as algae. (Alga- singular)
Macroscopic algae are referred to as
seaweeds.
4. Euglena
Live mostly in fresh water
Have plant and animal
characteristics
Use photosynthesis, but when
there’s not enough light, they
are consumers
Some don’t use photosynthesis
at all because they don’t have
chloroplast. Instead, they just
eat other protists or take in
nutrients
Move by using flagella to push
them through the water
5. Dinoflagellates Live mostly in salt water, but
some are found in fresh water
and snow.
Have flagella that make the
protists spin
Most use photosynthesis, but
some get food as consumers,
decomposers, or parasites
They are sometimes red and
produce a strong poison
When they produce very fast,
they cause red tide, where the
water turns red and the
shellfish eat it, making the
shellfish poisonous to all
vertebrates.
6. Animal-like protists: Protozoans
they are heterotrophs and can move around. They are
multicellular. Their means of movement are through
their flagella and cilia.
Amoeba- moves using pseudopodia ( “false
feet” ), which are like extensions of the
cytoplasm.
Ingests food by surrounding and engulfing
food (endocytosis)
Reproducing by binary fission (mitosis)
can cause amebic dysentery in humans –
diarrhea and stomach upset from drinking
contaminated water
7. Animal-like protists: Protozoans
PARAMECIUM
move using cilia
exhibits avoidance
behavior
reproduces asexually
(binary fission) or
sexually (conjugation)
outer membrane pellicle- is rigid and
paramecia are always the
same shape, like a shoe
9. Funguslike protists
Thrive in moist, damp places where there is a lot of
rotting organic matter.
Fungus-like protists are heterotrophs with cell
walls. All fungus-like protists are able to move at
some point in their lives. There are essentially three
types of fungus-like protists: water molds, downy
mildews, and slime molds.
Often brightly colored
Change form during life cycle
Tend to live in damp locations
