,What type of cells are all human cells Eukaryotic cells.
classified as?
What distinguishes eukaryotic cells Eukaryotic cells are larger, more complex, contain
from prokaryotic cells? membrane-bound organelles, and have a well-
defined nucleus.
What is the role of histones in Histones allow DNA to supercoil into chromosomes
eukaryotic cells? within the nucleus.
What is the primary function of Ribosomes are protein factories that read
ribosomes? messenger RNA and build proteins.
What are the two types of Rough ER (involved in protein synthesis and folding)
endoplasmic reticulum? and Smooth ER (involved in steroid hormone
synthesis and detoxification).
What is the function of the Golgi It processes and ships proteins from the ER to their
apparatus? final destinations.
What role do lysosomes play in the Lysosomes break down cellular substances and are
cell? involved in cellular health.
What is the function of peroxisomes? Peroxisomes detoxify compounds using oxidative
enzymes and are essential for myelinating nerve
cells.
What is the primary function of Mitochondria are the energy factories of the cell,
mitochondria? generating ATP through oxidative phosphorylation.
, What is the structure of the plasma The plasma membrane is a phospholipid bilayer with
membrane? hydrophilic heads facing outward and hydrophobic
tails facing inward.
What does amphipathic mean in Amphipathic means that one end of the
relation to phospholipids? phospholipid is hydrophilic (water-loving) and the
other end is hydrophobic (water-fearing).
What are integral proteins? Integral proteins span the entire phospholipid
bilayer and are involved in various functions such as
transport and signaling.
What are peripheral proteins? Peripheral proteins attach to only one surface of the
membrane or are indirectly anchored through
interactions with other proteins.
What are the eight core functions of Movement, conductivity, metabolic absorption,
cells? secretion, excretion, respiration, reproduction, and
communication.
How do cells specialize through As cells become specialized for one function, they
differentiation? often lose the ability to perform others.
What is the role of communication in Communication allows cells to coordinate their
cellular functions? activities, functioning as an integrated organism.
What is the function of metabolic Cells take in nutrients from their surroundings, with
absorption in cells? intestines and kidney cells specializing in this
function.
