Teas 6 Science Complete Answer Key 2026 | Complete Solutions Updated Hierarchy of Structures - answer - 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 - answer - *-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 - answer - *-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 - answer - Highly condensed, threadlike rods of DNA. *DNA* is genetic material that stores information about the plant or animal. Chromatin - answer - Consists of the *DNA* and *Proteins* that make up chromosomes. Nucleolus - answer - 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 - answer - *Encloses* the nucleus. Consists of *inner and outer membranes made of lipids.* Nuclear Pores - answer - Involved in *exchange of material between nucleus and the cytoplasm.* Nucleoplasm - answer - Liquid *within* the membrane and is *similar* to cytoplasm. Cell Membrane - answer - *"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 - answer - 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 - answer - Inside the cell. Contain: Ribosomes, Golgi Apparatus, Vacuoles, Vesicles, Cytoskeleton, Microtubules, Cytosol, Cytoplasm, Cell Membrane, Endoplasmic Reticulum, Mitochondria Ribosomes - answer - 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 - answer - Involved in *synthesizing materials* like *proteins* that are transported *out* of the cell. ~*Modifies and Packages proteins* secreted from the cell. -Located near the nucleus and has layers of membranes. Vacuoles - answer - Sacs used for *storage, digestion, and waste removal*. -Plant: Has *one large* vacuole -Animal: Has *small, sometimes numerous* vacuoles. Vesicles - answer - Small organelle *within* a cell, ha
