Small structures within a cell that perform special functions
Organelles
Substance that fills and holds cell contents
Cytoplasm
Respnsible for ribosome formation
Nucleolus
What breaks down toxins
Smooth Endoplasmic Reticulum
What has rough appearance due to ribosomes and processes proteins
Rough Endoplasmic Reticulum
What packages secretions for export or cell use
Golgi complex
What converts nutrients from food into ATP for energy
Mitochondrion
What is composed of RNA and functions in protein synthesis
Ribosome
What has round "bags" of digestive enzymes and there function is disabling bacteria and viruses, detoxification of harmful substances, digesting old and worn-out organelles, breaking down nutrients and degrading no-useful tissues
Lysosome
What detoxifies a njmber of harmful substances and the most important function is to "disarm" free radicals by converting them to hydrogen peroxide
Peroxisomes
Hydrogen peroxide is converted to water by what enzyme
Catalase
What is Diffusion
THE movement o fmolecules from a region of higher concentration to one of lower concentration
what is Osmosis
The process by which water molecules diffuse through the cell membrane
What is hypertonic
High solute concentrations outside of cell, water leaves cell, then cell shrinks
What is hypotonic
High solute concentration inside of cell, water rushes in, cell swells and ultimately bursts
What is phagocytosis
Engulfing or swallowing large particles by the cell membrane
