Specialisation Flashcards
What is cell specialization?
The process by which generic cells change into specific cells with distinct functions.
True or False: All cells in an organism have the same structure and function.
False
What is the primary purpose of cell specialization?
To allow cells to perform specific functions efficiently.
Fill in the blank: Cells that have a similar structure and function are called ______.
tissues
Multiple Choice: Which of the following is an example of a specialized cell? A) Skin cell B) Muscle cell C) Neuron D) All of the above
D) All of the above
What role do stem cells play in cell specialization?
Stem cells can differentiate into specialized cell types.
True or False: Specialized cells can revert back to stem cells.
False
What is the function of red blood cells?
To transport oxygen throughout the body.
Fill in the blank: Nerve cells are specialized for ______.
transmitting signals
Multiple Choice: Which type of cell is specialized for contraction? A) Epithelial cell B) Muscle cell C) Neuron D) Blood cell
B) Muscle cell
What is the primary function of epithelial cells?
To cover and protect surfaces of the body and organs.
True or False: Specialized cells can perform multiple functions at once.
False
What is the significance of the shape of a cell in relation to its function?
The shape of a cell is often adapted to its specific function.
Fill in the blank: White blood cells are specialized for ______.
immune response
Multiple Choice: Which of the following cells is specialized for nutrient absorption? A) Liver cell B) Neuron C) Muscle cell D) Epithelial cell
D) Epithelial cell
What is differentiation in the context of cell specialization?
The process by which a cell becomes specialized for a specific function.
True or False: All cells in the human body are specialized.
False
What type of cell is responsible for transmitting electrical signals?
Neuron
Fill in the blank: The specialized cells that help in movement are called ______.
muscle cells
Multiple Choice: Which cell type is involved in protecting the body from pathogens? A) Red blood cell B) White blood cell C) Muscle cell D) Nerve cell
B) White blood cell
True or False: Specialized cells can only be found in multicellular organisms.
True
What is one key feature of muscle cells that aids their function?
They contain many contractile proteins.
Fill in the blank: Cells that line the surfaces of organs and cavities are called ______ cells.
epithelial
Multiple Choice: Which of the following is NOT a type of specialized cell? A) Blood cell B) Bone cell C) Stem cell D) Neuron
C) Stem cell
What is a key characteristic of all specialized cells?
They have unique structures that enable them to perform their specific functions.
What are stem cells?
Stem cells are undifferentiated cells that have the potential to develop into various cell types in the body.
True or False: Stem cells can only be obtained from embryos.
False: Stem cells can also be obtained from adult tissues and umbilical cord blood.
What ethical concerns are associated with the use of embryonic stem cells?
The main ethical concern is the destruction of human embryos, which some believe is equivalent to taking a human life.
Which type of stem cells are considered pluripotent?
Embryonic stem cells are considered pluripotent, meaning they can differentiate into any cell type.
Multiple Choice: What is a potential benefit of using adult stem cells? A) Greater ethical acceptance B) Higher pluripotency C) Easier to obtain
A and C
True or False: Stem cell therapy has been proven to be effective for all medical conditions.
False: While promising, stem cell therapy is still being researched for many conditions and is not universally effective.
What is the main argument for using stem cells in medical research?
The main argument is their potential to treat diseases and injuries by regenerating damaged tissues and organs.
