🎯 WALT & Success Criteria

We Are Learning To:

• Identify and explain the structure and function of cells, tissues, organs and organ systems

• Compare specialised cells and their adaptations

• Analyse how cell structures support organism survival

Success Criteria - I can:

Label key organelles in plant and animal cells

Explain how specialised cells are adapted to their function

Describe the organisation: cells → tissues → organs → systems

Compare plant and animal organ systems

Dyslexia-Friendly Options: Read questions aloud to yourself or work with a partner for pair-reading

📚 Part A: Vocabulary & Knowledge

1. Match each term to its definition by drawing lines:

Organelle

Tissue

Chloroplast

Mitochondria

Cell wall

Group of similar cells working together

Powerhouse of the cell

Rigid structure supporting plant cells

Site of photosynthesis

Specialised structure inside a cell

2. Circle the correct answer for each:

a) Which organelle controls the cell?

Nucleus

Vacuole

Ribosome

b) Plant cells have _______ that animal cells don't have:

Nucleus and cytoplasm

Cell wall and chloroplasts

Mitochondria and ribosomes

3. Label the diagrams (use the word bank below):

Word Bank: nucleus, cell membrane, cytoplasm, mitochondria, chloroplast, cell wall, vacuole, ribosome

Support: Use all words from the word bank. Each word is used once.

✏️ Part B: Understanding & Analysis

4. Explain why red blood cells have a biconcave (doughnut) shape:

5. Compare how a root hair cell and a leaf cell are each adapted to their function:

Root hair cell:

Leaf cell:

6. Data Analysis: A student counted organelles in different cell types.

Organelle Count per Cell:

Muscle cell mitochondria: 2000

Skin cell mitochondria: 200

Leaf cell chloroplasts: 50

Root cell chloroplasts: 0

a) Explain why muscle cells have more mitochondria than skin cells:

b) Explain why root cells have no chloroplasts:

7. Extended Response (5 marks):

Explain how the organisation of cells → tissues → organs → organ systems helps multicellular organisms survive. Use examples from either plants OR animals.

Planning Scaffold:

• Define: cells, tissues, organs, organ systems

• Choose plant OR animal examples

• Explain advantages of this organisation

• Link to survival

Support sentence starters:

• Cells are organised into tissues because...

• An example of this organisation is...

• This helps organisms survive by...

Extension Challenge: Compare the advantages and disadvantages of multicellular vs unicellular organisation. Include examples of organisms and their adaptations.
