Why do animals need to breathe?
Breathing is important to organisms because cells require energy (oxygen) to move, reproduce and function. Breath also expels carbon dioxide, which is a by-product of cellular processes within the bodies of animals.
Respiration is the process of releasing energy from food and this takes place inside the cells of the body.
The process of respiration involves taking in oxygen (of air) into cells, using it for releasing energy by burning food, and then eliminating the waste products (carbon dioxide and water) from the body.
Respiration is essential for life because it provides energy for carrying out all the life processes which are necessary to keep the organisms alive.
The energy produced during respiration is stored in the form of ATP (Adenosine Tri- Phosphate) molecules in the cells of the body and used by the organism as when required.
KEY POINTS
Life started in an anaerobic environment in the so called ‘primodial broth’ (a mixture of organic molecules.
Subsequently, oxygen strangely enough became an crucial factor for aerobic metabolism especially in the higher life forms.
The rise of an oxygenic environment was an important event in the diversification of life.
It evoked a dramatic shift from inefficient to sophisticated oxygen dependent oxidizing ecosystems.
Anaerobic fermentation, the metabolic process that prevailed for the first about 2 billion years of the evolution of life, was a very inefficient way of extracting energy from organic molecules. Ex: A molecule of glucose, e.g., produces only two molecules of ATP (≈ 15 kCal) compared with 36 ATP molecules (≈ 263 kCal) in oxygenic respiration.
Aerobic metabolism must have developed at a critical point when the partial pressure of oxygen rose from an initial level to one adequately high to drive it passively across the cell membrane.
Respiration is a complex and highly integrated biomechanical, physiological, and behavioral processes.
The transfer of O2 occurs through a flow of tissue barriers and compartments by diffusion down a partial pressure gradient, which drops to about zero at the mitochondrial level.
Acquisition of molecular oxygen (O2) from the external fluid media (water and air) and the discharge of carbon dioxide (CO2) into the same milieu is the primary role of respiration.
The respiratory system is a biological system consisting of specific organs and structures.

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.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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.

2. CELLULAR RESPIRATION
● Cellular respiration is the process in
which the C-H bonds in food are
broken by Oxidation reduction (redox)
reactions and then energy is
transformed into ATP.
● Organisms get the oxygen, needed for
cellular respiration, from their
environment and provide it to their cells.
The carbon dioxide produced during
cellular respiration is taken out of the
cells and ultimately from the body.
3. AEROBIC RESPIRATION
In aerobic respiration, oxygen is used and there is complete oxidation of the food
material. Carbon dioxide and water are also produced in this process.
4. GASEOUS EXCHANGE
● Taking in oxygen and giving out of carbon
dioxide is termed as gaseous exchange.
BREATHING
● The term breathing is used for the process
through which animals take air in their bodies
to get oxygen from it and then give out the
air for getting rid of carbon dioxide. Thus
breathing and respiration are not
synonymous. Respiration involves the
mechanical and the biochemical
processes whereas breathing is only the
mechanical or physical process of
exchange of gases.
6. GASEOUS EXCHANGE IN PLANTS
● Plants have no organs or systems for the
exchange of gases with the environment.
Every cell of the plant body exchanges
gases with the environment by its own.
● The leaves and young stems have stomata
in their epidermis. The gaseous exchange
occurs through these stomata. The inner
cells of leaves (mesophyll) and stems also
have air spaces among them, which help in
the exchange of gases.
7. GASEOUS EXCHANGE IN PLANTS
● In young stems and leaves, some gaseous exchange also occurs through the
cuticle which is present over their epidermis.
8. LEAF CELLS FACE TWO SITUATIONS.
● During the daytime when the
mesophyll cells of leaves are carrying
out photosynthesis and respiration
side by side, the oxygen produced in
photosynthesis is utilized in cellular
respiration. Similarly the carbon
dioxide produced during cellular
respiration is utilized in
photosynthesis.
● During night when there is no
photosynthesis occurring, the leaf
cells get oxygen from the environment
and release carbon dioxide through
stomata.
9. ● ACTIVITY
● Draw diagram of stomata of a leaf indicating the movement of gases.
10. LENTICELS
● In woody stems and mature
roots, the entire surface is covered
by bark which is impervious to
gases or water. However, there are
certain pores in the layer of bark.
These are called the lenticels. The
lenticels allow air to pass through
them.
● Gases diffuse in and out of the
general surface of the young roots.
The gases are found in the soil
surrounding the roots.
