Cell Specialization Flashcards
Cell specialization definition
Cell specialization is when generic cells turn into specific types of cells that have particular jobs. For example:
- Muscle cells help with movement.
- Nerve cells send signals.
- Red blood cells carry oxygen.
This process allows different cells to work together effectively in an organism.
Development of specialized cells
During embryonic development, stem cells can differentiate into various cell types, such as muscle, nerve, or blood cells.
This process is guided by specific genes being turned on or off.
Specialized cells Functions
Specialized cells have specific organelles and structures that help them perform their functions efficiently.
For example, muscle cells have many mitochondria for energy, while neurons have long axons to transmit signals quickly.

What is Epithelial Tissue?
Function: Covers surfaces, lines cavities, and forms glands.
Examples: Skin epithelium, lining of the digestive tract.
Connective Tissue Function?
Supports, binds, and protects other tissues and organs.
Examples: Bone, blood, adipose (fat) tissue.
What’s Muscle Tissue Function?
Responsible for movement.
Types: Skeletal Muscle: Voluntary movement (attached to bones).
Cardiac Muscle: Involuntary movement (heart).
Smooth Muscle: Involuntary movement (walls of organs).
Nervous Tissue Function?
Transmits signals for communication within the body.
Examples: Neurons (nerve cells), glial cells (supporting cells).
Overall, functions of the different types of tissues? (
Epithelial Tissue: Protection, absorption, secretion, and sensation.
Connective Tissue: Support, storage (e.g., fat), transport (e.g., blood), and immune defense.
Muscle Tissue: Contraction for movement (voluntary or involuntary).
Nervous Tissue: Communication, coordination, and processing information.
What is the basic definition of tissues?
Tissues are essential for the structure and function of organs and systems in the body, with each type specialized for particular roles.
What’s a STEM CELL?
A stem cell is a unique type of cell that has the ability to develop into many different cell types in the body. They can divide and replicate themselves and have two main characteristics which is SELF RENEWAL and DIFFERENTIATION.
(STEM CELLS) what’s self renewal?
Stem cells can divide to produce more stem cells.
(STEM CELLS) whats Differentiation?
They can develop into specialized cells, such as muscle cells, nerve cells, or blood cells.
What’s the types of stem cells?
Embryonic Stem Cells, Adult (Somatic) Stem Cells, and Induced Pluripotent Stem Cells (iPSCs)
Embryonic Stem Cells
Derived from early embryos, they can develop into almost any cell type in the body.
