The kingdom Protista includes a diverse range of single-celled and simple multi-cellular eukaryotic organisms. While they differ greatly from one another, protists share characteristics of being eukaryotic with nuclei but less complex than other eukaryotes. Protists reproduce through both asexual and sexual means. They obtain food through photosynthesis, consuming other organisms or organic matter, or using multiple methods. Major groups of protists include algae, protozoa like amoebas and ciliates, slime molds, and diatoms.
Fungus comes from the Greek word mykes “Mushrooms”
They are Eukaryotic organism that digests food externally and absorbs nutrients directly through its cell walls. Consist of about 100,000 spp.
Based on NCERT class 9 Science Chapter 7 'Diversity in Living Organisms'. Describes how the classification is being made on the category of plants, animals, fungi, microbes etc. made by Vivek Ranjan Sahoo

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.
contains detailed information about classification of life system
in particular three domains of classification sytem of living organism
into prokarya archea eukarya
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.

This is a very old school report that I did back when I was in the 8th grade . It's basically information concerning the Six Kingdoms. I hope you can make use of it. So buckle up!
Microbiology - Algae
Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades.
Algae are sometimes considered plants and sometimes considered "protists" (a grab-bag category of generally distantly related organisms that are grouped on the basis of not being animals, plants, fungi, bacteria, or archaeans).
2. General Characteristics
Protists are very diverse and have few
traits in common
Most are single-celled organisms, but
some are many cells, and others live in
colonies
Some produce own food, others eat other
organisms or decaying matter
Some can control own movement, others
cannot
3. Characteristics that protists DO share:
Eukaryotic(have a nucleus), but are less
complex than other eukaryotic organisms
Do not have specialized tissues
Members of the kingdom Protista are
related more by how they differ from
members of other kingdoms than by how
they are similar to other protists
4. zooflagellates
Protists have many
different shapes
Pretzel slime
Most scientists
mold
ulva
agree that fungi,
plants, and animals
evolved from early
protists
Paramecium
5. Protists and Food
Protists can get food many ways:
Can make own food
Can eat other organisms
Can eat parts or products of other organisms
Can eat remains of other organisms
Some use more than one way to get food
Some produce food—they use chloroplasts
to produce food through photosynthesis
6. Finding
Food
Heterotroph: organism that cannot
make own food
Some are decomposers—they get
energy by breaking down dead
organic matter
7. Asexual Reproduction
Most protists
reproduce asexually
Offspring come from
just one parent
Binary fission: a
single-celled protist
divides into two cells
Each new cell is a
single-celled protist
9. Algae
Kinds of Protists
Allalgae have the
green pigment
chlorophyll, which is
used to make food
through
photosynthesis
Almost all algae live in
water
Free-floating, single-
celled algae are called
phytoplankton, which
produce much of the
world’s oxygen
10. Amoebas
Soft,jellylike
protozoans
Found in fresh and salt
water, soil, and in
parasites
Move with
pseudopodia, which
means “false feet”
11. Ciliates
Have hundreds of cilia—
tiny, hairlike structures
Cilia move the protist
forward by beating back
and forth—sometimes up
to 60 times a second!
Cilia are also used for
feeding—they move the
food towards the protist’s
food passageway
Best known of ciliates is
the Paramecium
12. Spore-Forming Protists
Many spore-forming
protists are parasites
They absorb nutrients from
their hosts
No cilia or flagella, cannot
move on their own
Have complicated life
cycles that usually
includes two or more hosts
Example: protist that
causes malaria uses both
mosquitoes and humans
as hosts
13. Slime Molds
Heterotrophic and can
only move during certain
periods of life cycle
Look like thin, colorful
globs of slime
Use pseudopodia to
move and eat fungi and
yeast
When environmental
conditions are stressful,
slime molds grow stalks
with knobs, which contain
spores
14. Red Algae
Most of world’s
seaweed is red algae
Most live in tropical
oceans
Usually less than 1 m
in length
Contain chlorophyll,
but have red pigment
Red pigment allows
them to absorb light
that filters deep into
ocean
15. Brown algae
Most seaweed in cool
climates are brown
algae
Attach to rocks or form
large floating beds in
ocean waters
Have chlorophyll and
yellow-brown pigment
Many are very large—up
to 60 meters
16. Green algae
Most diverse of protist producers
Green because chlorophyll is main pigment
Most live in water or moist soil
Others live in melting snow, on tree trunks, and
inside other organisms
17. Diatoms
Single-celled
Found in salt and fresh water
Get energy from photosynthesis
Make up a large percentage of phytoplankton
Cell walls contain a glasslike substance called silica
