8 SPECIALIZED CELLULAR FUNCTIONS
QUESTIONS AND ANSWERS WITH
SOLUTIONS 2024
Movement - ANSWER muscle cells can generate forces that produce motion
Conductivity - ANSWER a response to a stimulus is manifested by a wave of excitation, an electrical
potential that passes along the surface of the cell to reach its other parts
Metabolic absorption - ANSWER cells take in and use nutrients. Cells of the kidney and intestine are
specialized to carry out absorption
Secretion - ANSWER certain cells (mucous gland cells) can synthesize new substances from substances
they absorb and then secrete new substances to serve as needed elsewhere
Excretion - ANSWER all cells rid themselves of waste products resulting in metabolic breakdown of
nutrients
Respiration - ANSWER cells absorb oxygen which is used to transform nutrients into energy in the form
of ATP
Reproduction - ANSWER tissue growth occurs as cells enlarge and reproduce themselves. Tissues require
maintenance where new cells are produced to replace cells that are lost normally through cellular death
Communication - ANSWER critical for cell function and survival. Constant communication allows the
maintenance of homeostasis
