Specialised Cells and Cellular Differentiation - A comprehensive guide exploring how cells adapt their structure to perform specific functions in both plants and animals, covering key examples of specialised cells and their unique characteristics.

• Cell differentiation occurs when cells modify their structure to perform specific roles
• Plant specialised cells include xylem cells, palisade cells, and root hair cells
• Animal specialised cells include sperm cells, egg cells, and blood cells
• Each specialized cell type has unique structural adaptations for its function
• The process of cellular differentiation enables organisms to develop complex tissues and organs

<p>Specialised cells are cells that have become modified to perform a specific function, through a process called cellular differentiation.

Animal Specialised Cells

This section details specialised animal cells and their unique adaptations. The content focuses on reproductive cells and blood cells, demonstrating how cellular specialization enables complex biological functions.

Definition: The zona pellucida is a protective layer surrounding the egg cell, crucial for fertilization.

Example: Red blood cells lack nuclei to maximize space for hemoglobin, demonstrating cell differentiation and specialisation.

Highlight: White blood cells, particularly neutrophils and lymphocytes, show complex adaptations for immune function.

The section includes detailed information about:

Sperm cells with their motile structure and acrosome
Egg cells and their protective layers
Red blood cells' biconcave shape for oxygen transport
White blood cells' role in immune response

Vocabulary: Lysosomes are cellular structures containing digestive enzymes used by white blood cells to destroy pathogens.

I love this app so much, I also use it daily. I recommend Knowunity to everyone!!! I went from a D to an A with it :D

Philip, iOS User

The app is very simple and well designed. So far I have always found everything I was looking for :D

Lena, iOS user

I love this app ❤️ I actually use it every time I study.

Plant Specialised Cells

This section explores the fundamental types of specialised cells in plants and their specific functions. The text details three main types of plant cells and their structural adaptations.

Definition: Cell differentiation is the process where cells modify their structure to perform specific functions.

Example: Xylem cells are hollow to efficiently transport water through plants, demonstrating how structure relates to function.

Highlight: Palisade cells contain numerous chloroplasts specifically for photosynthesis, showing cell differentiation examples.

The section covers:

Xylem cells with their hollow structure for water transport
Palisade cells rich in chloroplasts for photosynthesis
Root hair cells with extensions to maximize nutrient absorption

Vocabulary: Chloroplasts are specialized cell structures where photosynthesis occurs.
