Hierarchy of Structures
Lowest Hierarchy level is at Organelles within a cell. They obtain energy from food and
reproduction.
-Cells with the same function are collected into larger groups called Tissues.
-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
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
-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
Highly condensed, threadlike rods of DNA. DNA is genetic material that stores information
about the plant or animal.
Chromatin
Consists of the DNA and Proteins that make up chromosomes.
Nucleolus
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
Encloses the nucleus. Consists of inner and outer membranes made of lipids.
Nuclear Pores
Involved in exchange of material between nucleus and the cytoplasm.
Nucleoplasm
Liquid within the membrane and is similar to cytoplasm.
Cell Membrane
"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.
~Proteins: Help give cells shape
~Special Proteins: Helps cell communicate with external environment.
~Other Proteins: Transport molecules across membrane
Selective Permeability
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 the surface.
-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
Inside the cell. Contain: Ribosomes, Golgi Apparatus, Vacuoles, Vesicles, Cytoskeleton,
Microtubules, Cytosol, Cytoplasm, Cell Membrane, Endoplasmic Reticulum,
Mitochondria
Ribosomes
