The document discusses endosymbiosis, which is when one organism lives inside the cells of another. According to the endosymbiosis theory, mitochondria and chloroplasts evolved from endosymbiotic bacteria that were engulfed by early eukaryotic cells but not digested. Primary endosymbiosis involved bacteria being engulfed, while secondary endosymbiosis occurred when the products of primary endosymbiosis were themselves engulfed, resulting in diverse algae. The theory proposes that modern eukaryotic cells are the result of multiple endosymbiotic events between bacteria and the original eukaryotic cell.
Extremophilic organisms are organisms that can survive exremities that are detrimental for other forms of life. Here is a presentation that discuss such microorganisms in detail
Introduction :
Mycorrhizae are mutualistic symbiotic associations formed between the roots of higher plants and fungi.
Fungal roots were discovered by the German botanist A B Frank in the last century (1855) in forest trees such as pine.
In nature approximately 90% of plants are infected with mycorrhizae. 83% Dicots,79% Monocots and 100% Gymnosperms.

Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes.

Explain endosymbiosis theory (Or \"How cells got mitochondria and chloroplasts\")
Solution
Symbiosis occurs when two different species benefit from living and working together. When
one organism actually lives inside the other it\'s called endosymbiosis.
Endosymbiosis occurred as:
a) The primitive eukaryotic cell was also eventually able to eat prokaryotes, a marked
improvement to absorbing small molecules from its environment;
b) The process of endosymbiosis commenced when the eukaryote engulphed but did not digest a
autotrophic bacterium. Evidence suggests this engulfed bacterium was an alphaproteobacteria, an
autotroph that uses photosynthesis to acquire energy.
c) The eukaryote then began a mutually beneficial (symbiotic) relationship with it whereby the
eukaryote provided protection and nutrients to the prokaryote, and in return, the prokaryotic
endosymbiont provided additional energy to its eukaryotic host through its respiratory cellular
machinary.
d) The relationship became permanent over time completing primary endosymbiosis as the
endosymbiont lost some genes it used for independent life and transferred others to the
eukaryote\'s nucleus. The symbiont thus became dependent on the host cell for organic
molecules and inorganic compounds. The genes of the repiratory machinary became a
mitochondrion. Endosymbiotic theory hypothesizes the origin of chloroplasts similarly, where
chloroplasts a eukaryote with mitochondria engulfs a photosynthetic cyanobacteruim in a
symbiotic relationship ending in the chloroplast organelle.
Endosymbiosis has gained ever more acceptance in the last half century, especially with the
relatively recent advent of sequencing technologies. There are many variants to the theory,
regarding what organism(s) engulfed what other organism(s), as well as how many times and
when it occurred across geological time..

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

3. Definition:-
Endosymbiosis (Greek: endon= "within",
sym = "together" and biosis = "living").
An endosymbiont is any organism that lives within
the body or cells of another organism.
4. What is Endosymbiosis?
The endosymbiosis theory attempts to explain the
origins of organelles such as mitochondria and
chloroplasts in eukaryotic cells.
According to Endosymbiosis theory:
modern eukaryotic cells evolved from simple,
phagotrophic cells that ingested bacteria and
cyanobacteria; the prey was not digested, and
physiological processes of the endosymbionts were
used by the host.
5. From prokaryote to eukaryote
Mitochondria developed
from proteobacteria,
and chloroplasts
from cyanobacteria.
6. How important is endosymbiosis?
Endosymbiosis explains the origin of mitochondria and
chloroplasts, but could it also explain other features of
the eukaryotic cell? Maybe. Endosymbiotic origins have
been suggested for many structures, including flagella,
cilia, and even the nucleus! However, scientists are still
actively debating whether or
not these structures
evolved through
endosymbiosis.
7. Mitochondria and chloroplasts (and maybe other
organelles) evolved from endosymbiotic bacteria.
Heterotrophic prokaryotes were engulfed and function as
mitochondria.
Photosynthetic prokaryotes were engulfed and function as
chloroplasts.
Eukaryotic cell is a chimera of prokaryotic ancestors [The
term chimera refers to the mixture of three prokaryotes].
a. Original contributes genome
b. One becomes mitochondrion
c. One becomes chloroplast
8. Primary & Secondary Endosymbiosis
Primary endosymbiosis involves the engulfment of a
bacterium by another free living organism. Secondary
endosymbiosis occurs when the product of primary
endosymbiosis is itself engulfed and retained by
another free living eukaryote. Secondary
endosymbiosis has occurred several times and has
given rise to extremely diverse groups of algae and
other eukaryotes.
