- Biodiversity refers to the variety of living things on Earth. Species evolve over time, with some going extinct and new species emerging.
- Scientists classify living things into five kingdoms based on their cells, number of cells, and how they obtain nutrition. The kingdoms are Monera, Protoctista, Fungi, Plantae, and Animalia.
- The Monera kingdom contains unicellular prokaryotic organisms like bacteria. The Protoctista kingdom includes unicellular and multicellular eukaryotes like algae and protozoa that lack tissues. Fungi are eukaryotic and may be unicellular or multicellular, feeding as heterotroph

1) Strategies and structuresIn Protozoans the method of movement .pdfaptelecom16999
1) Strategies and structures:
In Protozoans the method of movement is determined by the type of organism and the
surrounding environment. Protozoans mainly move by cell extension, flagella or pseudopodia
and cilia, the movement as per the presence of structure can be classified as ciliary, flagellar and
amoeboid movement.
Ciliates : Ciliates form the largest group of protozoa. These organisms vary in size and often live
in watery environments, including oceans, marshes, bays and streams. Ciliates move using tiny
cilia, which are hair-like strands that act as sensors and tiny limbs.
Flagella are longer and less numerous that cilia, they use their long tail like flagella to move.
Amoebas : In these two cytoskeleton get polymerized . This creates a vacancy and cytoplasmice
material flow to cover the vacancy created. When amoeba moves cytoplasm moves to the arm
like extension called pseudopodium. This pseudopodium extends and enlarge and hence this
push the animal body towards that respective direction.
2) A) Flagellates can live as single cells, in colonies, or as parasites.
Commonly live in niche\'s of water.
They conduct photosynthesis and have a cell wall.
They contain flagella for propulsion or to create a current to bring in food.
They can inhabit the reproductive tract, alimentary canal, tissue sites and also the blood stream,
lymph vessels and cerebrospinal canal.
B) Pseudopods : Also called as false feet , are projections that can appear and disappear from the
organism\'s body. These are used for movement and to engulf prey and digest them using
enzymes.
C) Apicomplexa : Unicellular and spore forming, most of them possess a unique form of
organelle that comprises a type of plastid called an apicoplast, and an apical complex structure.
They have apicoplast(non photosynthetic plastid) , mitochondria and nuclear genomes.
Lack of cilia, sexual reproduction, use micropores for feeding, and the production of oocysts
containing sporozoites as the infective form.
They have unique gliding capability which enables them to cross through tissues and enter and
leave their host cells. This gliding ability is made possible by the use of adhesions and small
static myosin motors.
3) Key characteristics of fungi :
Fungi are unicellular or multicellular.
Most of the fungi grow as tubular filaments called hyphae
They are haploid.
Fungus are heterotrophs (they can obtain nutrients by absorption) . They absorb food and secrete
enzymes to digest complex molecules
Propogate by spores
Asexual or sexual reproduction
They can be multinucleated
Fungi are achlorophyllous (lack of cholorphyll pigment)
Both Fungi and protists belong to same kingdom but fungi is different from protist, protists are
able to live in an anaerobic environment without oxygen but fungi need aerobic respiration to
survive.
Protists are unicellular but fungi are multicellular. Protists are autotrophic (make their own
energy) and heterotrophic (rely on outside source to get energy), but fungi a.
Fungi is most abundantly found organism in earth, almost all parts of earth we found earth, here we represent some characteristic with their uses and disadvantages .
Fungi are eukaryotic organisms that include microorganisms such as yeasts, moulds and mushrooms. These organisms are classified under kingdom fungi.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. • Biodiversity is the variety of living things in
our planet.
• Living beings evolve through time, so some
species get extinct, some species suffer
changes, and new species appear.
• The remains of
extinct living beings
are called Fossils.
7. • Protoctist Kingdom:
– Unicellular and multicellular.
– Eukaryotic Cells.
– They have no tissues.
– Autotrophs or heterotrophs.
Algae and Protozoa.
8. • Fungi Kingdom:
– Unicellular and multicellular.
– Eukaryotic Cells.
– They have no tissues.
– Heterotrophs.
Yeasts, Moulds, Mushrooms.
9. • Plant Kingdom:
– Multicellular.
– Eukaryotic Cells.
– They have tissues.
– Autotrophs.
Mosses, Ferns, Flowering Plants.
10. • Animal Kingdom:
– Multicellular.
– Eukaryotic Cells.
– They have tissues.
– Heterotrophs.
Invertebrates and Vertebrates.

23. Activity 2. Test yourself!
• Are these statements true or false?
1. Monera Kingdom includes animals and fungi.
2. Bacteria have prokaryotic cells.
3. Most bacteria are autotrophs.
4. Bacteria have capsule, cell wall and cell membrane.
5. Bacteria are classified by shape into four groups.
6. Bacillus are round.
7. Cyanobacteria are heterotrophs.
8. Bacteria are divided by binary fission.
25. • Protoctist Kingdom includes unicellular and
multicellular living things. They are eukaryotes,
and have no tissues.
• Protozoa and Algae are found in this kingdom.
26. PROTOZOA
• They are:
– Unicellular.
– Heterotrophs: they feed on bacteria, organic remains, and
other microscopic organisms.
– Aquatic, and they live in both salt water and fresh water.
– Some of them float on water and are food for animals, like
blue whales.
– Some of them are parasites, they live in other living things
bodies, and cause illnesses.
27. • There are four groups of Protozoa,
depending on the way they move:
1) Flagellates: they move using a flagellum.
2) Cilliates: they move using cillia
(hair-like organs)
28. 3) Rhizopods: they move using
pseudopods (projections of cell
cytoplasm).
4) Sporozoa: they have no movement. All of
them a parasites. Ex. Plasmodium causes
malaria.
29. Activity 3. What type of structures enables
each to move?
Pseudopods
Flagellum
Cannot move
Cillia
30. ALGAE
• They are:
– Unicellular or multicellular.
– Autotrophs: they contain chlorophyll and other
pigments which absorb the sunlight for
photosynthesis.
31. • There are three groups of algae, depending on
the photosynthetic pigment they use:
1) Green Algae: they use chlorophyll. They live
on the surface of fresh and salt water.
32. 2) Brown Algae: they use fucoxantine. They live only in
salt water. Some of them can be hundreds of metres
high (Sargazos).
33. 3) Red Algae: they use rodophyll. They live
deep in warm oceans.
34. Activity 4. Which type of algae…
1. Uses rodophyll to absorb the sunlight?
2. Lives only in salt water?
3. Lives near the surface in salt and fresh
water?
4. Uses chlorophyll to absorb the sunlight?
5. Uses fucoxantine to absorb the sunlight?
36. What do you remember about them?
1. Are their cells eukaryotic or prokaryotic?
2. Are they unicellular or multicellular?
3. Are they autotrophic or heterotrophic?
37. • Fungi are eukaryotic living things.
• They may be unicellular or multicellular.
• Fungi are heterotrophic, they do not make their own
food, so they feed on organic materials.
• There are three types of fungi: Yeasts – Moulds –
Mushrooms.
38. There are three groups of fungi:
1. Yeasts: unicellular fungi. Some are parasites, but
others are helpful. They are used to make bread,
beer, wine. They reproduce by budding.
39. 2. Moulds: multicellular fungi. Some are parasites, and
others feed on decomposing matter, like bread, fruit,
etc.
40. 3. Mushrooms: multicellular fungi. They feed on
organic dead matter, decomposing it. Some are
edible, but others are poisonous. They reproduce by
spores.
41. Parts of a Mushroom
• The mycellium is the part
that grows underground.
• The gills have the spores.
When they are disperssed,
they form anew mycellium,
which grows into a new
fungi.
42.
43. 1. Fungi are a type of plants, because they make their
own food.
2. Yeast are multicellular fungi.
3. Yeast feed on dead matter.
4. Yeast reproduce by bipartition.
5. Moulds are unicellular fungi.
6. Moulds have a mycellium, they grow on the soil.
7. Moulds feed on organic matter.
Activity 1. True or false? Correct the false ones.
44. 8. Mushrooms reproduce by spores.
9. The mycellium is the part that grows over the ground.
10. It is a good idea to pick up mushrooms using a plastic bag.
