Fungi are microscopic, filamentous organisms that reproduce sexually and asexually. They have hyphae that make up the mycelium or filamentous body of the fungus. Specialized structures include rhizoids for attachment, haustoria for nutrient absorption, and sclerotia or chlamydospores for surviving harsh conditions. Fungi reproduce through both sexual spores like ascospores and asexual spores including conidia.

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.
The topic of discussion is Kingdom plantae & Kingdom Animalia, The detailed characteristic of Thallophytes, Bryophytes & Pteridophytes along with Phanerogams such as Gymnosperms & Angiosperms have been discussed. The general characteristic of Virus (TMV) and Bacteriophage along with their life cycle are also discussed. Finally the ecologically important LIchens and Mycorrhizae are also discussed.
Fungus, plural fungi, any of about 99,000 known species of organisms of the kingdom Fungi, which includes the yeasts, rusts, smuts, mildews, molds, and mushrooms. There are also many funguslike organisms, including slime molds and oomycetes (water molds), that do not belong to kingdom Fungi but are often called fungi. Many of these funguslike organisms are included in the kingdom Chromista. Fungi are among the most widely distributed organisms on Earth and are of great environmental and medical importance. Many fungi are free-living in soil or water; others form parasitic or symbiotic relationships with plants or animals.
A fungus (/ˈfʌŋɡəs/; plural: fungi[3] or funguses[4]) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, Fungi, which is separate from the other eukaryotic life kingdoms of plants and animals.
A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Similar to animals, fungi are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesise. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the Eumycota (true fungi or Eumycetes), which share a common ancestor (form a monophyletic group), an interpretation that is also strongly supported by molecular phylogenetics. This fungal group is distinct from the structurally similar myxomycetes (slime molds) and oomycetes (water molds). The discipline of biology devoted to the study of fungi is known as mycology (from the Greek μύκης, mukēs, meaning "fungus"). In the past, mycology was regarded as a branch of botany, although it is now known fungi are genetically more closely related to animals than to plants.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
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.
