Life Processes - 5

Class 10
Welcome Back 
We're here to study Life Processes
& This time we start with Human Nutrition

Today we'll cover:

1. Digestive System - Diagram
2. Digestion in Mouth
3. Passage of food through food pipe 
4. Peristalsis

So here's the Video

Watch the video, understand the concepts & then try to answer the following questions:

1.Which two types of digestion occur in mouth? Does any type of digestion occurs in Oesophagus?

2.What are the three components of saliva? What are their roles?

3.Define Peristalsis?

4.Draw a labelled diagram of Human Digestive System.

5.Name one type of movement performed by your body while you take a nap after lunch.

Enjoy 👍👍

Life Processes 4

Welcome Back 

This one's for class 10 students.

This is the 4th one for Life Processes. In this we'll start with Heterotrophic Nutrition. 

The Topics we've already covered are:

1. Movements in living organisms
2. Autotrophic Nutrtion

The topics covered in this one are:

1. Types of Heterotrophic Nutrition
2. Holozoic Nutrtion
3. Nutrition In Amoeba & Paramecium

Now without further ado, here's the video for above topics

Try to follow the video, watch it till the time concepts are clear to you.

I've also given you some questions to check your understanding of the concepts covered. Please remember that these answers to these questions are not to be crammed and written. 

Try writing them after watching the video, in your own words. Your answers should reflect the understanding of your concepts.

Sharing the questions here too

´What is heterotrophic nutrition?

´What is the role of decomposers in our environment?

´Write the difference between nutrition of Herbivore, Carnivore & Omnivore. Give 3 examples of each.

´Give some examples of parasitic organisms. Try giving at least one example from both plants and animals.

´What is the role of decomposers in our environment??

Good Luck. Happy Learning & Stay safe 👍

REPRODUCTION IN ORGANISMS PART 3

Sexual Reproduction:

Learning Outcomes: 

After watching this video you will be able to:

1. Define and deduce the key features of sexual reproduction 
2. Identify the patterns of sexual reproduction 
3. Classify organisms on the basis of patterns
4. Understand key terminologies related to sexual reproduction 

Also, I’ve uploaded the video lectures on you tube. So hereafter I’ll be sharing links:

I'll also recommend a watch of this wonderful video on Marsupials.

Watch the video, and thereafter I’ll be sharing a few questions based on topics covered.

Happy Learning 

LIFE PROCESSES (PART III): NUTRITION IN PLANTS

This video post is for Class X students. continuing the previous lecture on Nutrition in Plants. In this video we'll cover the following:

1.  Experiment to determine carbon dioxide is essential for photosynthesis
2. Stomata: Opening & Closing Mechanism

With this we conclude the material on Nutrition in Plants, in the Life Processes lesson.

You'll be solving the questions given.

LIFE PROCESSES II (NUTRITION)

In the next in the series of video for class X, Lesson 6, here is a short video explaining:

1. What is Nutrition
2. Types of Nutrition
3. Autotrophic Nutrition
4.  Activity to show chlorophyll is essential for photosynthesis

Leave queries & comments.

Good Luck

FUNDAMENTAL UNIT OF LIFE (PART II)

CLASS IX

Continuing with previous lecture on Cell: Fundamental Unit of Life for Class IX

This one covers #CellMembrane to develop a basis for study of transport across cell membrane.

Please follow carefully.

This video is followed by 4 more to develop an understanding of the types of transport across cell membrane.

Next we'll be doing some questions on the topics covered till now.

Understand, enquire & apply.

REPRODUCTION IN ORGANISMS PART II

In continuation with our previous discussion about introduction of first chapter, I'm uploading the second part.
In this part we'll be discussing Asexual reproduction: Modes & Significance.
Go through the video and try solving the assignments in between as well as at the end.

Class IX: Fundamental Unit Of Life (Part 1)

Welcome to Class 9.

Here is a lecture VDO for Chapter 5 of NCERT Class 9 Science Books.

Listen carefully and make notes based on the slides.

Happy Learning

Ask questions, clear doubts. Stay in touch

Reproduction In Organisms VDO Lecture

Covid 19 has put on hold many things. The one thing it need not derail is learning.

So here I'm uploading lecture for the first topic of #ClassXII Biology Lesson 1, Reproduction In Organisms.
