LESSON TO BE TAUGHT

Chapter : 8 — Cell – Structure and Functions

MY FOCUS

CLASS – VIII, D

NO. OF PERIODS REQUIRED : 5

1. Cell and its discovery 2. Variations in shapes and sizes 3. Unicellular and Multicellular organisms 4. Tissue 5. Basic components of cell – Cell membrane, cyloplasm and nucleus etc. and their functions. 6. Prokaryotic and Eukaryotic cells 7. Comparison of plant and animal cells

STUDENT ACTIVITY PRACTICE ASSESSMENT

To analyse the structure of a plant cell using onion peel. Q1. Ans.

Differentiate between multicellular and unicellular organisms. Unicellular Organisms – Organisms that are made up of only one cell are called unicellular ogranisms. For e.g. – Amoeba, Yeast, Paramecium etc. Multicellular Organisms – Organisms that are made up of more than one cell are called multicellular organisms. For e.g. – Plant and animal cell

Q2. Ans.

What is a cell wall? Write its function. The additional layer surrounding the cell membrane in plants is known as cell well. It is absent in animal cell. It provides to the plant.

Q3. Ans.

Why is the nucleus called the control centre of the cell? Nucleus is called the control centre of the cell because it gives direction for all the activities of the cell.

ADDITIONAL

1. Chromosomes are composed of DNA and protein.

INFORMATION

2. DNA molecules contain the information necessary for constructing and organising cells. 3. Full form of DNA is Deoxyribo Nucleic Acid.

CAN DO STATEMENTS

1. Students are able to differentiate between unicellular and multicellular organisms. 2. Students are able to understand about different components of cells like cytoplasm, nucleus and their functions. 3. Students are able to differentiate between prokaryotes and eukaryotes and plant cell and animal cell.
