Hey there. Here is the brand new lesson on photosynthesis. Enjoy!
PHOTOSYNTHESIS
Learning outcomes
Content: to be able summarise the process of photosynthesis, to identify the reactants and products of photosynthesis, to describe the main structures involved in photosynthesis.
Language: to recall structures involved in photosynthesis and their functions precisely and concisely.
Put the given words and phrases into the gaps.
algae
sugar
chlorophyll
chloroplasts
Only certain organisms, called autotrophs, can do photosynthesis; they need the presence of (A)___, a special pigment (colour) that can absorb (soak up) light and convert light energy into chemical energy. Photosynthesis uses carbon dioxide and water to assemble (put together) (B)___ molecules (usually glucose) and releases oxygen into the air. Eukaryotic autotrophs, such as plants and (C)___ (seaweed), have organelles (special parts of cells) called (D)___ in which photosynthesis happens.
2. In five sentences or less, list the major steps involved in photosynthesis using picture below.
Hey there, it's Ildar Yakhin. Today's lesson is an update for the last one on BLOOD. Enjoy then
Blood 2 lesson
Exercise 7 (individual work): A young astronaut from a distant galaxy has recently returned home from a year of ‘intercultural’ exchange on Earth. The astronaut reports back to his boss on the blood of Earthlings. Complete the intergalactic astronaut’s conversation with his boss.
Exercise 8 (individual work): Complete the following text using - ‘a/an’ (the indefinite article), ‘the’ (the definite article) or nothing (simply leaving the line blank).
Now pretend you are ___ cell scientist. ___ cell you are looking through your microscope is ___ red blood cell of ___ human body. This cell has ___ flexible and biconcave structure.
High or low number of ___ RBCs in ___ patients blood would describe his or her illness. If there is ___ low number of erythrocytes then the patient has ___ anemia.
Exercise 9. Step one (individual work). Read the text and circle the right words or phrases in italics to create grammatically correct sentences.
Blood is a fluid/liquid connective tissue critical to/to thetransportation/transport of nutrients, gases, and wastes throughout/among the body; to defend/defeat the body against infection and other threats; and to/to the homeostatic regulation of pH, temperature, and other internal/external conditions. Blood is composed of formed elements—erythrocytes, leukocytes, and cell/the cell fragments called platelets—and a fluid extracellular matrix called plasma. Like other fluids in/in the body, plasma is composed/consist primarily of water: In fact, it is about 92 percent water. Dissolved or suspended within this water is a mixture of/of the substances, most of which are proteins/fats. There are literally/almost hundreds of substances dissolved or suspended in the plasma, although many of them is/arefinded/found only in very small quantities.
Step two (individual work)
Compare your results with the correct answers shown by your teacher.
Exercise 10. Step one (individual work). Put the following sentences in a logical order to form a well-sequenced paragraph about ABO blood groups.
_1_A. Although the ABO blood group name consists of three letters,
___B. Both are glycoproteins.
___C. In which case they are blood type AB.
_4_D. People whose erythrocytes have A antigens on their erythrocyte membrane surfaces are selects blood type A, and those whose erythrocytes have B antigens are blood type B.
___E. ABO blood typing selects the presence or absence of just two antigens, A and B.
___F. People with neither A nor B antigens are selects blood type O.
_5_G. People can also have both A and B antigens on their erythrocytes
_8_H. ABO blood types are genetically figured out.
Hey there everybody. Here is the brand new lesson on Blood and its components. Enjoy!
Circulatory System. Blood 1.
Learning Outcomes:
Content: to be able to name blood cell types and be able to explain their functions; to be able to explain what blood consists of and know its functions.
Language: clearly and concisely summarise facts and describe their interrelationships.
1 (individual work): Write down words which you know about the circulatory system.
2 (individual work): Circle the right words or phrases in italics to create grammatically correct questions.
Questions
Answers
1. How many/much RBCs does the one drop of blood have?
2. How many/much blood does the organism have?
3. How are the RBCs, the red blood cells, different from/different by the leukocytes?
4. What are the red blood cells named/called?
5. Is it true/Is true that the thrombocytes consist of cell parts and make a clot?
3 (individual work): Match the following correct answers to the questions above. There are two extra answers that cannot be used.
Yes, it is true. They consist of different cell parts and dead cells.
Yes, there are.
Erythrocytes or RBCs.
There are 5.5 million.
They are flexible and biconcave, and carry oxygen.
Five to seven litres.
Yes, it does.
4 (individual work): Answer questions after watching the video (https://goo.gl/iSyfWp).
What are functions of the blood?
What are components of the blood?
5 (pair work): Using what you have learned, draw the shape of different blood cells.
The ___(A) may travel throughout the body in the bloodstream, it will affect the activity only of its ___(B). Hormones play a very important role in the ___(C) of physiological processes because of the target cell responses they control. These ___(D) related to human reproduction, growth and development of body tissues,___(E), fluid balance, sleep, and many other body functions.
2 pair work. Answer questions after watching video (https://goo.gl/gsWLc1). Check if you know these words before watching.
pancreas
nutrient
to aid
enzyme
digestive
to split
to enrich
flushed
faulty
to trigger
3 team work. Answer questions.
Why do you think the pancreas has to be on constant alert for sugars entering your blood stream?
Imagine you are a food entering the digestive system, explain why pancreatic enzymes are so important for helping you achieve your goal of enriching the bloodstream with nutrients.
4 individual work. Fill in the blanks by using given words.
a.T3 and T4b.Thyroid-stimulating hormonec.Reduces blood glucose levelsd.Testosteronee.Glucagon
Content: to be able to differ functions and way of work of endocrine and nervous system; to be able to name the endocrine gland and its hormones and functions;
Language: to be able to explain main events in endocrine and neural signalling.
Hmmm?!
Endocrine communication involves chemical signalling by the release of hormones into the bloodstream and travel to some organ, where they make a response in target cells.
