Page 2: Stem Cells and Their Applications

This section discusses what is stem cell research and its various applications in medicine and plant science.

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

Highlight: Plant stem cells, found in meristems, can differentiate into any plant cell type and are useful for cloning.

Example: Adult stem cells from bone marrow can replace faulty blood cells in medical treatments.

Quote: "Therapeutic cloning creates embryos with the same genetic information as the patient, reducing rejection risks."

Page 3: Chromosomes and Cell Cycle

This page details the structure of chromosomes and the cell cycle process.

Definition: Chromosomes are coiled DNA structures carrying genetic information.

Highlight: Body cells contain two copies of each chromosome, one from each parent.

Vocabulary: Cell cycle - The process of cell growth, DNA replication, and division.

Example: Multicellular organisms use mitosis for growth and cell replacement.

Page 1: Specialised Cells and Their Functions

This page explores various specialised cells in biology and their functions. The content details how different cells are adapted for specific roles within organisms.

Definition: Cell specialisation occurs when cells develop specific structures to perform particular functions.

Example: Root hair cells have extended surfaces to maximize water absorption, while nerve cells are elongated for rapid signal transmission.

Highlight: Muscle cells contain numerous mitochondria to generate energy for contraction, demonstrating how structure relates to function.

Vocabulary: Differentiation - The process by which cells become specialized for specific functions.

Page 4: Mitosis and Cell Division

This section explains the detailed process of mitosis and cell division.

Definition: Mitosis is the process of cell division resulting in two identical daughter cells.

Highlight: DNA replication occurs before cell division, ensuring each new cell has complete genetic information.

Example: Chromosomes align at the cell's center before being pulled apart by cellular fibers.

Vocabulary: Cytoplasm - The material within a cell excluding the nucleus.
