Science Flashcards
What is a specialized cell?
A cell that is uniquely adapted to perform a specific function.
Give an example of a specialized cell and its function.
Red blood cells transport oxygen around the body.
What is a unicellular organism?
An organism made up of a single cell.
True or False: Unicellular organisms can carry out all the functions of life within a single cell.
True
What is the function of a nerve cell?
To carry electrical impulses around the body.
What is the function of a sperm cell?
To fertilize an egg cell.
What is the function of a muscle cell?
To contract and relax to produce movement.
What is the function of a root hair cell?
To absorb water and minerals from the soil.
What is the function of a white blood cell?
To defend the body against infection.
What is the function of a palisade cell?
To carry out photosynthesis in plants.
Which type of cell is more complex: a specialized cell or a unicellular organism?
A specialized cell
What is the main difference between a specialized cell and a unicellular organism?
Specialized cells work together to form tissues and organs, while unicellular organisms are single-celled organisms.
What is the advantage of having specialized cells in multicellular organisms?
They can perform specific functions more efficiently, leading to greater overall function and survival.
What is the disadvantage of unicellular organisms compared to multicellular organisms?
They have limited complexity and cannot perform specialized functions as efficiently.
How do specialized cells contribute to the overall function of an organism?
By working together in tissues and organs to carry out specific tasks that support the organism’s survival.
