Cell Biology and Organisation - A comprehensive guide covering differences between eukaryotic and prokaryotic cells, cell structures, and organisation levels in living organisms. This essential biology topic explores cellular components, their functions, and how cells work together in complex organisms.

Key points:

  • Distinguishes between eukaryotic and prokaryotic cells, highlighting key structural differences
  • Examines functions of plant cell organelles and specialized cellular structures
  • Explores cell division, differentiation, and how stem cells are used in medical treatments
  • Details principles of organisation from cells to organ systems
  • Covers enzyme function and their role in biological processes

MNA 4.1.1 4.1.1.1 Eukaryotes and prokaryotes B4.1 Cells and Movement KNOWLEDGE ORGANISER Cell structure There are 2 types of cell: eukaryote

View

Page 2: Stem Cells and Specialized Cells

This page delves into stem cell applications and specialized cell functions, covering therapeutic cloning and microscopy techniques. The content explores both practical and ethical considerations in stem cell research.

Definition: Therapeutic cloning involves using undifferentiated stem cells to treat medical conditions by injecting matching stem cells into patients.

Example: Stem cells can potentially cure paralysis by differentiating into new nerve cells in the spine, or treat leukemia by forming new white blood cells.

Highlight: Specialized cells have specific adaptations for their functions, such as sperm cells with numerous mitochondria for energy production.

Quote: "The use of stem cells is an ethical issue because the stem cells come from embryos which are then destroyed."

Stem Cells and Cell Specialization

This section covers the therapeutic applications of stem cells and their potential in medical treatments.

Definition: Stem cells are undifferentiated cells capable of developing into different cell types.

Highlight: Therapeutic cloning uses stem cells to treat various medical conditions, including potential treatments for paralysis.

Example: Stem cells matching a patient's tissue type are injected to minimize rejection risk.

Cell Division and Chromosomes

This section explains the process of cell division and the role of chromosomes in genetic inheritance.

Definition: Chromosomes are DNA-containing structures that carry genetic information.

Highlight: Human cells typically contain 46 chromosomes in pairs.

Vocabulary: Mitosis - the process of cell division resulting in two identical daughter cells.

Active Transport and Cellular Adaptations

This section details how substances move across cell membranes and cellular adaptations for efficient transport.

Definition: Active transport moves substances against concentration gradients using energy.

Example: Plant root hairs absorb mineral ions from soil using active transport.

Highlight: Single-celled organisms have advantageous surface area to volume ratios for efficient substance transport.

Principles of Organisation

This section explores how cells work together to form more complex structures.

Definition: Tissues are groups of similar cells working together for a specific function.

Example: Muscular tissue enables movement through contraction.

Vocabulary: Organ systems - groups of organs working together to perform specific functions.

Page 1: Cell Structure and Types

This page introduces the fundamental differences between eukaryotic and prokaryotic cells, along with detailed cell structures. Plant and animal cells are classified as eukaryotes due to their membrane-bound organelles and nucleus, while bacterial cells are prokaryotes with simpler organization.

Definition: Eukaryotic cells contain membrane-bound organelles and a true nucleus, while prokaryotic cells lack these features and contain a single DNA loop.

Highlight: All cells, regardless of type, possess basic structures including a cell membrane and cytoplasm.

Example: Plant cells contain unique structures like chloroplasts for photosynthesis, vacuoles filled with cell sap, and cellulose cell walls for strength.

Vocabulary: Organelles - specialized structures within cells that perform specific functions.
