Page 10: Plant Cloning

The final parts of Question 3 deal with plant cloning:

Reasons for cloning plants
Advantages of tissue culture for plant cloning
Components of growth medium for tissue culture

Question 4 begins, focusing on plant root structure.

Highlight: Understanding plant cloning techniques is important for the AQA GCSE Biology Paper 1 exam.

Page 11: Root Structure and Function

Question 4 tests knowledge of plant root structure and function:

Identifying the type of microscope used to create an image
Calculating the real length of a root hair using magnification
Explaining how root hair cells are adapted for water uptake

Example: Students must calculate the real length of a root hair given its magnified image size and magnification factor.

This page concludes the provided transcript of the GCSE Biology Paper 1 Higher Tier exam questions.

Page 2: Cell Structure Question

This page begins Question 1, which focuses on cell structure and identification.

The question presents diagrams of an animal cell and an algal cell, asking students to:

Identify the type of cell shown
State the function of the cell wall
Identify which part makes the algal cell green

Example: Students must identify structures like the nucleus, cytoplasm, and chloroplasts in the cell diagrams provided.

Vocabulary: Key terms introduced include bacterium, cellulose cell wall, and chloroplasts.

View

Page 3: Cell Organelles

This page continues Question 1, testing knowledge of cell organelles and their functions.

Students are asked to:

Match subcellular structures to their functions
Identify the correct procedure for obtaining a clear microscope image

Definition: Subcellular structures are specialized parts within a cell that perform specific functions, such as mitochondria for energy production.

View

Page 4: Microscopy Skills

This section of Question 1 assesses practical microscopy skills. Students must:

Measure the length of a nucleus and cell in millimeters
Calculate the relative size of the cell compared to the nucleus

Highlight: These questions test important practical skills required for the AQA GCSE Biology Paper 1 exam.

View

Page 5: Magnification Calculations

The final part of Question 1 involves a magnification calculation. Students must:

Use the formula: magnification = size of image / size of real object
Calculate the magnification of a cell given its image size and real size

Question 2 begins on this page, focusing on animal cell structure.

Example: A sample calculation is provided: If the image width is 40 mm and the real width is 0.1 mm, students must determine the magnification.

View

Page 6: Animal Cell Structure

Question 2 continues, testing knowledge of animal cell structure and function. Students are asked to:

State the function of the nucleus
Name a cell type without a nucleus
Draw and label a simple animal cell diagram
Identify a structure found in plant cells but not animal cells

Vocabulary: Key terms include nucleus, plant cell, and animal cell.

View

Page 8: Plant Cell Structure

Question 3 continues, testing knowledge of plant cell structure and organization. Students must:

Match levels of organization (cell, tissue, organ) to plant parts
Identify where a specific plant cell would be found
Calculate the length of a chloroplast from a scale diagram

Definition: Levels of organization in biology refer to the hierarchy of structures from cells to tissues to organs and beyond.

View

Page 9: Plant Cell Specialization

This page focuses on plant cell specialization and tissue culture:

Explaining why root cells don't photosynthesize
Understanding cell differentiation in root hair formation
Introducing the concept of plant cloning through tissue culture

Vocabulary: Key terms include differentiation, metabolism, and tissue culture.
