This page focuses on cell differentiation in animals and plants, explaining how cells become specialized for specific functions.
Cell differentiation is the process by which a fertilized egg or zygote develops into specialized cells with specific roles in the organism. In animals, cells differentiate to form various systems:
Definition: Cell differentiation - The process by which cells develop specialized structures and functions to perform specific roles in an organism.
In plants, specialized cells include:
Each type of specialized cell has adaptations suited to its function. For example:
Example: Palisade mesophyll cells in plants are specialized for photosynthesis, with many chloroplasts to capture light energy.
The page also introduces the concept of stem cells, which are undifferentiated cells that can develop into various cell types. This is an important topic in GCSE Biology and often features in exam questions.
Highlight: Understanding cell differentiation and specialization is crucial for topics like organ systems and plant structure in GCSE Biology revision.
This page explores the concept of cell differentiation in animals and plants. All multicellular organisms begin as a fertilized egg or zygote, which then differentiates into various specialized cell types to fulfill specific functions.
Specialized cells in animals and their functions:
Specialized cells in plants and their functions:
Vocabulary: Zygote - A fertilized egg cell resulting from the fusion of male and female gametes.
Highlight: Cell differentiation is a crucial process that allows multicellular organisms to develop complex structures and perform diverse functions.
This page introduces the concept of stem cells and their role in cell differentiation. Stem cells are unspecialized cells that can develop into various cell types. The page appears to be incomplete, but it suggests that adult cells can also differentiate under certain conditions.
Definition: Stem cells - Unspecialized cells with the ability to develop into different cell types, playing a crucial role in growth, repair, and regeneration of tissues.
Highlight: The study of stem cells and adult cell differentiation has significant implications for regenerative medicine and tissue engineering.

Eukaryotic and prokaryotic cells are the two main types of cells found in living organisms. This page covers their key differences and characteristics.
Prokaryotic cells are typically found in bacteria and are smaller (0.2-2.0 μm) compared to eukaryotic cells. They have a simpler structure with DNA found free in the cytoplasm and reproduce through binary fission.
Eukaryotic cells are larger (5-100 μm) and more complex, found in animals, plants, and fungi. They contain membrane-bound organelles like the nucleus, mitochondria, and chloroplasts (in plants).
Vocabulary: Prokaryotic cells - simpler cells without a nucleus, typically found in bacteria Vocabulary: Eukaryotic cells - more complex cells with a nucleus and organelles, found in animals, plants, and fungi
The page also covers specialized eukaryotic cells and their adaptations:
Example: A sperm cell has a tail for swimming, many mitochondria for energy, and an enzyme-filled acrosome to penetrate the egg.
The page concludes with information on microscopy techniques:
Highlight: Understanding cell structure and specialization is crucial for GCSE Biology revision and exam success.
