GCSE Specialized Cells

What are specialized cells?

• Cells that can perform any function in an organism.

• Cells that have specific structures and functions that enable them to perform particular tasks in an organism.

• Cells that are identical in structure and function.

• Cells that only exist in multicellular organisms.

What is the structure of muscle cells?

• Muscle cells are short, thick fibers that can expand to help the organism move.

• Muscle cells are long, thin fibers that can contract to help the organism move.

• Muscle cells are spherical cells that store energy for movement.

• Muscle cells are flat, wide cells that provide support to the organism.

What is the significance of the structure of red blood cells?

• Red blood cells have a spherical shape that helps them store more oxygen.

• Red blood cells have a biconcave shape that increases their surface area for oxygen absorption and allows them to easily navigate through blood vessels.

• Red blood cells are flat and thin, which helps them to absorb nutrients more efficiently.

• Red blood cells are elongated, which allows them to carry more carbon dioxide.

How do white blood cells (macrophages) function in the body?

• They produce antibodies to neutralize toxins.

• They help defend the body against infections by engulfing and destroying pathogens.

• They transport oxygen throughout the bloodstream.

• They regulate blood sugar levels.

How do specialized cells contribute to the overall function of an organism?

• They perform all functions independently without collaboration.

• They work together to perform complex functions that are essential for the survival and health of the organism.

• They only function during specific times of the day.

• They are only important for reproduction.

What is the role of cilliated epithelial cells?

• They absorb nutrients in the intestines.

• They provide structural support to tissues.

• They move substances using a sweep-like motion.

• They produce mucus in the respiratory tract.

What is the adaptation found in the ovum (egg cell)?

• The ovum has a large cytoplasm to help the zygote grow after fertilization.

• The ovum is small and compact to fit within the uterus.

• The ovum has a thick outer shell to protect it from damage.

• The ovum contains enzymes to aid in the digestion of sperm.

What type of specialized cell carries oxygen throughout the body?

• White blood cells

• Platelets

• Red blood cells

• Plasma cells

What is the function of the white blood cell?

• To carry out immune responses to protect the organism from pathogens like viruses and harmful bacteria.

• To transport oxygen throughout the body.

• To aid in the digestion of food in the stomach.

• To produce hormones that regulate metabolism.
