ClassX Video Lessons Youtube Channel Smile and Learn English The cell: Structure, functions and its parts – Science for kids
Have you ever wondered what makes up all living things? The answer is cells! A cell is the tiniest unit of life, and it’s so small that we can’t see it without a microscope. Even though they’re tiny, cells are super important because they do a lot of work to keep living things alive.
Cells have many jobs. Here are some of the things they do:
Organisms can be made up of one cell or many cells. Let’s see the difference:
Cells come in two main types: prokaryotic and eukaryotic. Here’s what makes them different:
If you want to learn more about cells and other cool science topics, you can try out the Smile and Learn platform. It’s full of games, videos, and interactive stories that make learning fun. You can even try it for free for a month on your mobile, tablet, or PC!
Create a 3D model of a cell using craft materials. Choose either a plant or animal cell and include all the major organelles. Label each part and explain its function. This will help you visualize the cell’s structure and understand the role of each component.
Play a game of charades where you act out different cell functions like energy transformation or mitosis. Your classmates will guess which function you are demonstrating. This activity will reinforce your understanding of what cells do in a fun and interactive way.
Use a microscope to observe real cells. Look at prepared slides of plant and animal cells. Draw what you see and compare the structures. This hands-on activity will give you a closer look at the differences between cell types.
Create a chart comparing prokaryotic and eukaryotic cells. Include details about their structures, examples of organisms, and any unique features. This will help you organize your knowledge and see the differences between these cell types clearly.
Write a short story from the perspective of a cell. Describe a day in its life, including how it takes in nutrients, transforms energy, and divides. This creative exercise will help you think about the cell’s functions in a narrative form.
Here’s a sanitized version of the provided YouTube transcript:

A cell is the smallest unit of life in living organisms. Cells are so small that we cannot see them with our naked eyes. They have different structures and functions, but all cells are made up of an outer coating and a water-based interior where organelles are found. Cells are alive, and some of their functions include:
– Nutrition
– Transformation of substances into energy
– Structural changes
– Growth and mitosis, allowing them to control their own growth and division
There are unicellular and multicellular organisms, depending on the number of cells they consist of. Unicellular organisms are very small and consist of only one cell; bacteria are examples of unicellular organisms. Multicellular organisms are made up of a large number of cells; trees, animals, and human beings are examples of multicellular organisms.
Based on their structure, cells are grouped into prokaryotic and eukaryotic cells. The main characteristic of prokaryotic cells is that DNA, the genetic material, is floating in the cytoplasm instead of being stored in a nucleus; bacteria are prokaryotic cells. The main characteristic of eukaryotic cells is that their nucleus is protected by a membrane, and DNA is found inside. Eukaryotic cells contain organelles located in the cytoplasm and can be classified as plant cells or animal cells.

This version removes any unnecessary repetition and maintains clarity while preserving the essential information.
Cells – The basic building blocks of all living things. – All plants and animals are made up of cells.
Nutrition – The process by which living organisms obtain and use food to support their life processes. – Proper nutrition is essential for the growth and repair of cells in our body.
Energy – The ability to do work or cause change, which living organisms obtain from food. – Plants use sunlight to produce energy through photosynthesis.
Growth – The process by which living organisms increase in size and develop. – The growth of a plant can be observed as it sprouts from a seed and becomes taller.
Organisms – Any living thing, from the smallest bacteria to the largest animal. – Bacteria, plants, and animals are all examples of organisms.
Unicellular – Consisting of a single cell. – Amoebas are unicellular organisms that live in water.
Multicellular – Consisting of many cells. – Humans are multicellular organisms with specialized cells for different functions.
Prokaryotic – Cells that do not have a nucleus or other membrane-bound organelles. – Bacteria are examples of prokaryotic organisms.
Eukaryotic – Cells that have a nucleus and other membrane-bound organelles. – Plants and animals have eukaryotic cells.
DNA – The molecule that carries the genetic instructions for life. – DNA determines the characteristics of living organisms and is passed from parents to offspring.
