Hierarchy of Structures
Ans: Lowest Hierarchy level is at Organelles within a cell. They obtain
energy from food and reproduction.
© 2026 Assignment
-Cells with the same function are collected into larger groups called
Tissues.
Guru01 - Stuvia
Expert
-Tissues are collected into Organs, carry out single task, like oxygenated
blood (lungs), or filter out waste (kidneys).
-Organs work together in systems that perform coordinated large-scale
functions, like nourishing the body (digestive) or protecting the body
from attacks (immune).
Cell Parts
Ans: -Organelles: Cell parts that function within a cell. They coordinate
with other organelles to performs a cell's basic function, like energy
processing and waste excretion.
~Examples: Ribosomes, Golgi Apparatus, Mitochondria, The Nucleus.
The Nucleus
Ans: -Nucleus: Small structure that contains Chromosomes and Regulates
the DNA of a cell. Defining structure of eukaryotic cells. It is responsible
for the passing on of genetic traits between generations.
-Contains: nuclear envelope, nucleoplasm, a nucleolus, nuclear pores,
chromatin, and ribosomes.

Chromosomes
Ans: Highly condensed, threadlike rods of DNA. DNA is genetic material
that stores information about the plant or animal.
Chromatin
Ans: Consists of the DNA and Proteins that make up chromosomes.
Nucleolus
Ans: Structure contained within the nucleus, consists of proteins. Small,
Round, and does not have a membrane. Involved in protein synthesis,
and synthesizes and stores RNA.

Nuclear Envelope
Ans: Encloses the nucleus. Consists of inner and outer membranes made
of lipids.
Guru01 - Stuvia
Expert
Nuclear Pores
Ans: Involved in exchange of material between nucleus and the
cytoplasm.
Nucleoplasm
Ans: Liquid within the membrane and is similar to cytoplasm.
Cell Membrane
Ans: "Plasma Membrane"
-Made of Lipids and Proteins
-Isolates the cell from its external environment while still enabling the
cellar to communicate with the outside environment.
-Consists: Phospholipid bilayer with the hydrophilic ends of the outer
layer facing external environment.
~Cholesterol: Adds stiffness and flexibility
~Glycolipids: Help cell to recognize other cells of the organisms.
, 3
~Proteins: Help give cells shape
~Special Proteins: Helps cell communicate with external environment.
~Other Proteins: Transport molecules across membrane
Selective Permeability
Ans: With regard to size, charge, and solubility.
-Size: Membrane allows small molecules to diffuse through it. Oxygen
and Water molecules are small and can pass through the cells membrane.

-Charge: Ions on a cells surface either attracts or repels ions. Ions with
like charges are repelled, and ions with opposite charges are attracted to
Guru01 - Stuvia
the surface.
Expert
-Solubility: Molecules that are soluble in phospholipids can usually pass
through the membrane. Many are not able to diffuse the membrane, and
if anything they'll have to be moved through by active transport and
vesicles.
Cell Structures
Ans: Inside the cell. Contain: Ribosomes, Golgi Apparatus, Vacuoles,
Vesicles, Cytoskeleton, Microtubules, Cytosol, Cytoplasm, Cell Membrane,
Endoplasmic Reticulum, Mitochondria
Ribosomes
Ans: Involved in synthesizing proteins from amino acids.
-Make up about a quarter of a cell.
-Some are embedded in the Rough Endoplasmic Reticulum (Rough ER)
Golgi Apparatus
Ans: Involved in synthesizing materials like proteins that are transported
out of the cell.
~Modifies and Packages proteins secreted from the cell.
, 4
-Located near the nucleus and has layers of membranes.
Vacuoles
Ans: Sacs used for storage, digestion, and waste removal.
-Plant: Has one large vacuole
-Animal: Has small, sometimes numerous vacuoles.
Vesicles
Ans: Small organelle within a cell, has a membrane.
© 2026 Assignment
-Functions: Moving materials within a cell.
Guru01 - Stuvia
Expert
Cytoskeleton
Ans: Consist of microtubules that help shape and support the cell.
Microtubules
Ans: Part of cytoskeleton.
-Help support the cell.
-Made of proteins
Cytosol
Ans: Liquid materials in the cell. Mostly water, also contains floating
molecules.
Cytoplasm
Ans: Refers to Cytosol and the substructures (organelles) found within
the plasma membrane, but not within the nucleus.
Cell Membrane
Ans: Acting as a barrier. Helps keep cytoplasm in and substances located
outside the cell out.
-Helps determine what is allowed to exit and enter.
