Different Tissues Work Together to Keep Us Alive

Think and Wonder!

Can you run without muscles?

Can your heart beat without muscle tissue?

How does water reach the leaves of a tall tree?

Why does your skin protect your body?

Big Idea:
A group of similar cells performing a specific function forms a tissue. Different tissues work together to keep plants and animals alive.

Learning Objectives

• Understand the meaning of tissue.
• Recognize different tissues in plants and animals.
• Explain how tissues perform specialized functions.
• Describe how tissues work together.
• Relate tissues to everyday life.

Competencies

Competency	Evidence
Observation	Identifies tissues in diagrams and models.
Conceptual Understanding	Explains tissue functions.
Critical Thinking	Predicts effects if a tissue stops working.
Application	Connects tissues to daily activities.
Communication	Explains tissue teamwork.

Learning Outcomes

• Defines tissue correctly.
• Identifies major plant and animal tissues.
• Explains functions of muscle, epithelial, nervous and connective tissues.
• Explains the role of xylem and phloem.
• Describes how tissues cooperate for survival.

Life Connect

• Running involves muscle tissue.
• Touching a hot object involves nervous tissue.
• Skin protects us through epithelial tissue.
• Blood transports materials through connective tissue.
• Xylem carries water from roots to leaves.

What Does This Teach Us?

• No tissue works alone.
• Cooperation is essential for life.
• Every part has an important role.
• Specialization increases efficiency.

Moral Values

• Teamwork leads to success.
• Every individual is important.
• Help others and work together.
• Respect all living organisms.
• Take care of your body.

MCQ Assessment

1. A group of similar cells performing a specific function is called:

Tissue Organ Cell Organism

2. Which tissue helps us run and jump?

Muscle tissue Xylem Phloem Blood

3. Which tissue protects the body surface?

Epithelial tissue Muscle tissue Blood Bone

4. Which tissue carries messages in the body?

Nervous tissue Muscle tissue Blood tissue Xylem

5. Which plant tissue carries water?

Xylem Phloem Epidermis Cortex

6. Which plant tissue transports food?

Phloem Xylem Epidermis Meristem

7. Blood is a type of:

Connective tissue Muscle tissue Nervous tissue Epithelial tissue

8. Growth in plants occurs due to:

Meristematic tissue Xylem Phloem Cortex

9. The heart mainly contains:

Muscle tissue Epithelial tissue Bone tissue Xylem

10. Tissues working together form:

Organ Cell Tissue Nucleus

HOTS Questions

1. What would happen if muscle tissue stopped working?

Movement and heartbeat would stop.

2. Why is skin important for survival?

It protects the body from injury, germs and water loss.

3. Why do plants need xylem and phloem together?

Xylem carries water while phloem transports food.

4. Why are tissues compared to members of a team?

Each tissue has a specific role and all work together.

5. Can one tissue alone keep an organism alive? Explain.

No. Different tissues depend on each other for survival.
