Name of the Unit: The cell Duration: 40 mints
Name of the Lesson: Cytoplasm Date:
CURRICULAR STATEMENT
Develop factual, conceptual, procedural, metacognitive knowledge, process skill and attitude on cytoplasm through lecture
method, group discussion and evaluation by questioning, group work and group discussion.
CONTENT ANALYSIS
NEW TERMS:
Cytoplasm, endoplasmic reticulum, mitochondria, ribosome, golgi bodies, centrosome and lysosome
FACTS:
• Cytoplasm is a transparent, jelly-like living substance which fills the interior of an animal and plant cell
• It is present between the cell membrane and the nucleus
• It contains a number of minute living structures known as the cell organelles

2. • Each cell organelles performs a specific functions for the cell
• Cell organelles are enclosed by membranes
• Endoplasmic reticulum is a system of membranes within the cytoplasm of plant and animal cells. It forms a link between the
cell and nuclear membrane and is the site of protein synthesis. It helps in the transport of substances within the cell.
• Mitochondria are rod or oval shaped structures, bounded by two membranes and concerned with the release of energy from
food during respiration. They are referred to as the power house of the cell.
• Ribosomes are granules attached to the endoplasmic reticulum or found freely in the cytoplasm. They help in the synthesis of
proteins.
• Golgi bodies are small, hollow, plate-like or cup-shaped bodies found in animal cells. They synthesize, store and secrete
enzymes and proteins. The Golgi apparatus in plant is known as dictyosome.
• Centrosome consists of centrioles. It helps in cell division.
• Lysosomes are present in animal cells only. They contain enzymes for cellular digestion.
CONCEPTS
MINOR CONCEPTS
• Cytoplasm contains living and non-living structures
• Cytoplasm present between cell membrane and the nucleus
MAJOR CONCEPT
• Both plant and animal cells contain various cell organelles

TEACHING LEARNING RESOURCES
1. Chart showing the diagram of cytoplasm and cell organelles
2. Handouts containing description about cell organelles
3. Activity cards containing questions related to the topic
CLASS ROOM INTERACTION PROCEDURE PUPIL RESPONSES
INTRODUCTION
Teacher makes a rapport with students by asking questions related to the topic.
 What is the basic unit of life?
 Can you name the membrane inside the cell wall?
 Is there any matter present inside the cell membrane?
 Can you name that matter?
Today we are going to study about Cytoplasm.

5. PRESENTATION
ACTIVITY-I
Teacher shows a chart showing the diagram of cytoplasm and cell organelles and
explained it.

6. BLACK BOARD
Cell organelles
 Endoplasmic reticulum
 Ribosome
 Centrosome
 Mitochondria
 Golgi bodies
 lysosomes
Teacher ask questions based on the diagram
• Define cytoplasm?
• Name the major cell organelles?
ACTIVITY-II
Teacher divides the students into groups and gives the handouts containing
infirmations about each cell organelles and ask the group leader to read it.

7. ENDOPLASMIC RETICULUM
• A system of membranes within the cytoplasm of plant and animal cells
• It forms a link between the cell and nuclear membrane
• It is the site of protein synthesis
Function
• Helps in the transport of substances within the cell
MITOCHONDRIA
• Rod or oval shaped structures
• Bounded by two membranes
• These are known as the power house of the cell
Function
• Release of energy from food during respiration
RIBOSOME
• These are granules attached to the endoplasmic reticulum or found freely in
the cytoplasm

8. • Found in both plant and animal cells
Function
• Help in the synthesis of proteins
GOLGI BODIES
• Small, hollow, plate-like or cup-shaped bodies found in animal cells
• The Golgi apparatus in plants is known as dictyosome
Function
• Synthesize, store and secrete enzymes and proteins
CENTROSOME
• Star-like structures found mostly in animal cells
• It consists of centrioles
Function
• Helps in cell division

9. LYSOSOME
• Present in animal cells only
• Contain enzymes for cellular digestion
• Suicidal bags of the cell
Teacher ask questions related to the cell organelles
• What is the function of endoplasmic reticulum?
• Whuch cell organelle is known as the power house of cell? Why?
• What is the function of ribosome?
• What are golgi bodies?
• Which cell organelle is known as the suicidal bag of the cell? Why?
Consolidation
Cytoplasm contains a number of minute
living structures known as the cell
organelles. Each cell organelle perform
specific functions.

10. ACTIVITY-III
Teacher gave activity cards containing questions related to the topic and asks the
pupil to fill it.
Find out the correct cell organelle based on the underlined statement and rewrite
the statement

transport of substance within the cell.
2. I am star-like structures found mostly in animal cell helps in cell division.
3. I contain enzymes for cellular digestion, known as the suicidal bag of the cell.
4 I am granules attached to the endoplasmic reticulum or found freely in the
cytoplasm, associated with synthesis of proteins.
