lesson-cell structure and functions(POST 4 )

Good morning boys ! In the last class we learnt about the functions of cell organelles and the differences between plants and animal cells.
As a quick recap, see if you can answer the following questions-
1. Name two cell organelles that are found only in plant cells.
2. Which organelle is called the power house of the cell?
3. Which plastids give colour to fruits and flowers?
4. Which cell organelles help in cellular digestion?
Great if you could answer these! Incase you could not ,please revisit the last blog or pages 131 of your reader.

  LEARNING OUTCOMES OF THIS CLASS-
By the end of the lesson you will be able to-
. name unicellular organisms
.list the identifying features of some unicellular organisms like amoeba, paramecium etc

Today we are going to learn about single celled or unicellular organisms that can perform all basic activities of life and live independently.

1. AMOEBA
It is an unicellular aquatic animal, that is irregular in shape and has body projections called pseudopodia, that help to catch its prey.



2. PARAMECIUM-
It is a slipper -shaped unicellular aquatic animal. Its body is covered with small hair - like projections called cilia that enable it to to move fast in water.

3. EUGLENA
It is a spindle- shaped green coloured unicellular animal. It has a long thread like flagellum at its anterior end, that helps it in movement. It takes food in through its gullet.



4. CHLAMYDOMONAS
It is a unicellular  green colour aquatic plant that has a whip-like structure called flagella that helps it to float in water.

5. YEAST
It is a unicellular plan( Fungi). It causes fermentation of foods containing carbohydrate.

A QUICK CHECK!

NAME THE UNICELLULAR ORGANISM WITH HELP OF THE CLUES GIVEN: ( Do them orally )
1. Has false feet called pseudopodia.
2. Has hair -like structures called cilia.
3. Is spindle -shaped.
4. It causes fermentation in foods containing carbohydrates.
5. Is a slipper-shape aquatic animal.
6. An aquatic animal with a flagellum.
HOMEWORK

1. Do question D on page 134 in your rough notebook and later in your reader .
2. Do questions A,B on page 135 in your rough notebook and later in your reader .
3. Do questions A,B on page 136 in your rough notebook and later in your reader .

lesson -cell structure n function ( POST 2)

Image
Good morning boys! In the last class we learnt that- . Cell is the basic structural and functional unit of life. .Depending on the number of cells , organisms can be grouped as unicellular or multicellular. . The size of a cell is related to its functions. LEARNING OUT COMES- By the end of this class you will be able to- .name the three basic parts of a cell and state their functions .distinguish between a eukaryotic and prokaryotic cell Today we are going to learn about CELL STRUCTURE .a A typical cell consists of three basic parts : 1 .  CELL MEMBRANE OR PLASMA MEMBRANE - . It forms the outer boundary of the cell, gives shape and size  to the cell. . It only allows certain selected substances to enter or leave the cell ( it is semi-permeable ). . It separates the cells from one another  and also from the surrounding medium. NOTE - In PLANT CELLS and BACTERIA there is an outer wall surrounding the cell membrane ,it is called the CELL WALL. It gives protection again

LIGHT-POST 2

Dear Learners, BOYS, WE HAVE A GOOGLE MEET FROM 9am -9.20 am, PLEASE ATTEND IT(THE MEET ID HAS BEEN POSTED ON YOUR CLASS GROUP). AFTER 9.20 ,READ THE BLOG. In the previous blog, we have learned about light and reflection of light. Let me help you to recall few important points 1. Light is a form of energy that enable us to see. 2. There are two laws of reflections.  Today, we will be learning about regular and irregular reflection, real and virtual images. Happy Learning!😊 At the end of it, you will be able to: 1. Differentiate between regular and irregular reflection. 2. Differentiate between real and virtual image. so, lets start the chapter......... When a ray of light falls on a reflecting surface, it get reflected. the amount and the direction of the light reflected depends on the nature of the surface. Depending upon the nature of the reflecting surface, there are two types of reflections. Click the link:  https://www.youtube.com/watch?v=f0NtpGe
