The document discusses the types and functions of plant cells. It defines a plant cell as the smallest unit that can function independently in a plant. It then describes several key organelles in plant cells and their functions, including: the cell membrane, which controls material flow; chloroplasts, which perform photosynthesis; mitochondria, which produce energy; the nucleus, which controls cell activities; the cell wall, which provides structure and protection; and the vacuole, which provides structure. It provides examples of specific plant cell types like root hair cells, guard cells, and palisade cells. It also explains the importance of cells for plant structure and processes like transportation, and what would happen if plants did not have cells.

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.

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

1. The Types and Function of Plant Cells
Project from: Karthikeyan Rajagopal
Class: 1 Iskandar
What is a plant cell?
Quick questions.
A cell is the smallest part of a plant that is able to function
independently. Every plant is made up of millions of cells.
Hello guys, today I am
going to share with you
about my Power point
presentation. Sit back and
enjoy.
2. Cell membrane
• Controls the flow of materials in
and out of the cell.
Chloroplast
• Absorbs light energy for the
process of photosynthesis.
Mitochondria
• Produces energy for reactions.
Nucleus
• Controls all activities in the
cell.
• Contains chromosomes consisting
of deoxyribonucleic acid (DNA)
that carries genetic information.
Cell wall
• Provides support, protection and fixed
shape to the cell.
Vacuole
• Provides support to
cells when filled with cell
sap.
Cytoplasm
• Acts as a medium where
chemical reactions occur.
Example plant cell structure:
3. Root hair cells
Root hair cells increase the
surface area to absorb more water
and nutrient from the soil.
Guard cells
Guard cells control the opening and closing of stoma.
A stoma is a small pore between the guard cells. The stoma is usually
open during the day to carry out photosynthesis. The stoma is closed
at night or when the plant loses a lot of water on a hot day.
Palisade cells
Contain chlorophyll to absorb
sunlight to carry out photosynthes
Epidermal cells
Function to reduce water loss,
allow gaseous exchange and
absorption of water and nutrient.

5. So guys, what happens to the plant if they don’t have any cell? If cell wall is absent in plant cell then all the
functioning of all the cell organelles present inside the cell would be affected as diffusion of various substanc
not occur. Due to absence of turgor pressure, the cell will not beat the concentration of solution (either hyper
hypotonic) and will burst.
What happens if plants didn’t have any cells?
