Page 2: Yeast Cell Structure

This page examines the structure of yeast cells through a detailed diagram showing key cellular components including the cell wall, nucleus, cell membrane, and vacuole.

Definition: Yeasts are microorganisms utilized in industrial processes such as brewing and baking.

Vocabulary: Key cellular components shown include:

Cell wall: Rigid outer layer
Nucleus: Contains genetic material
Cell membrane: Controls substance movement
Vacuole: Storage compartment
Cytoplasm: Gel-like substance where cellular processes occur

Page 3: Blood Component Analysis

This page presents a comparative analysis of blood components between a healthy person and two other individuals, examining variations in red blood cells, white blood cells, and platelets.

Example: The data shows significant variations in white blood cell counts, with Person A showing elevated levels compared to the healthy person.

Highlight: The analysis focuses on three key blood components:

Red blood cells (normally 5 x 10¹² per dm³)
White blood cells (normally 7 x 10⁹ per dm³)
Platelets (normally 3 x 10¹¹ per dm³)

Page 4: Osmosis Investigation

This page details an osmosis investigation in potato cubes GCSE biology practical, outlining the experimental method and presenting results graphically.

Definition: Osmosis is the movement of water molecules from an area of higher water concentration to an area of lower water concentration across a partially permeable membrane.

Example: The investigation involves measuring mass changes in potato cubes placed in different concentrations of salt solution.

Page 5: Transport Mechanisms

This page explores different cellular transport mechanisms including osmosis, diffusion, and active transport, with particular focus on their roles in single-celled organisms.

Vocabulary: Key transport mechanisms include:

Diffusion: Movement of molecules along concentration gradient
Active transport: Movement against concentration gradient using energy
Osmosis: Movement of water molecules across membranes

View

Page 6: Microscopy Calculations

This page focuses on microscopic measurements and calculations using an image of Vibrio cholerae bacteria.

Example: The page includes a calculation converting measurements from millimeters to micrometers using a magnification factor of ×8000.

Highlight: The flagellum measurement exercise demonstrates practical application of microscopy calculations in biological contexts.

Page 1: Introduction to Cell Basics Assessment

This page introduces an Edexcel GCSE biology key concepts revision assessment focusing on cell basics. The examination is structured as a timed assessment lasting 21 minutes with a total of 17 marks available.

Highlight: This assessment forms part of the Key Concepts in Biology section of the Edexcel GCSE (9-1) specification.
