A 2024 UPDATE.
,What is differentiation or maturation? - ANS-Process by
which cells become specialized.
What are the eight specialized cellular functions? - ANS-
Movement, conductivity, metabolic absorption, secretion,
excretion, respiration, reproduction, and communication.
What are the three general components of a eukaryotic cell?
- ANS-Plasma membrane, cytoplasm, and intracellular
organelles.
What is the function of the nucleus? - ANS-Cell division and
control of genetic information.
What is cytoplasm? - ANS-Aqueous solution that fills the
cytoplasmic matrix.
What are organelles? - ANS-Structures suspended in the
cytoplasm, enclosed in biological membranes.
What is the function of the endoplasmic reticulum? - ANS-
Synthesis and transport of protein and lipid components.
, What is the Golgi complex responsible for? - ANS-
Processing and packaging proteins into secretory vesicles.
What are lysosomes? - ANS-Sac-like structures that contain
digestive enzymes.
What do lysosomal enzymes do? - ANS-Digest most cellular
substances to their basic form.
What happens when there is cellular injury? - ANS-Release
of lysosomal enzymes, causing cellular self-digestion.
What are peroxisomes? - ANS-Organelles similar to
lysosomes that contain enzymes using hydrogen peroxide.
What is the function of mitochondria? - ANS-Contain
enzymes for cellular energy metabolism and produce ATP.
What is the cytoskeleton? - ANS-Internal skeleton of the cell
composed of protein filaments.
