Question | Answer |
The smallest living units in our bodies | Cells |
"Little organs" that carry on essential functions of cells | Organelles |
Direct chemical reactions in cells, Biological catalysts that speed up all of the chemical reactions that take place in a cell | Enzymes |
The sum of all chemical reactions in the cell | Metabolism |
The main components of a cell (3) | Plasma membrane, Cytoplasm, Nucleus |
The components of a plasma membrane (3) | Lipid bilayer, Integral proteins, Peripheral proteins |
The function of the plasma membrane | Provides a barrier against substances outside the cell |
Molecules move from a region where they are more concentrated to an area where they are less concentrated | Simple Diffusion |
The simple diffusion of water across a membrane, Water moves from a higher concentration to a lower concentration | Osmosis |
The mechanism by which particles enter cells | Endocytosis |
"Cell Eating," Defense mechanism of the host, Many white blood cells carry out this function | Phagocytosis |
"Cell Drinking," Many cells of the digestive system will use this process to sample the nutrients of the tissue fluid | Pinocytosis |
The mechanism that moves substances out of the cell, Secretory cells will use this process | Exocytosis |
The substance that lies internal to the plasma membrane, Consists of cytosol, organelles and inclusions | Cytoplasm |
Jelly-like fluid in which other cellular elements are suspended, Consists of water, ions and enzymes | Cytosol |
An organelle constructed of proteins and ribosmoal RNA (rRNA), Site of protein synthesis | Ribosomes |
The organelle with ribosomes "studding" the external surfaces, Produces proteins and stores ionic calcium | Rough Endoplasmic Reticulum (Rough ER) |
The organelle that consists of tubules, Site of lipid metabolism and stores ionic calcium | Smooth Endoplasmic Reticulum (Smooth ER) |
The organelle referred to as the "post office" of the cell, Sorts products of rough ER and sends them to the proper destination | Golgi Apparatus |
The organelle referred to as the "powerhouse" of the cell, Generates most of the cell's energy (ATP) | Mitochondria |
The organelle that digests unwanted substances, Membrane-walled sacs containing digestive enzymes | Lysosomes |
The organelle that breaks down long chains of fatty acids, Membrane- walled sacs of oxidase and catalase enzymes | Peroxisomes |
The organelle referred to as the "cell skeleton," Serves as the cell's bones, muscles and ligaments | Cytoskeleton |
The control center and genetic information of the cell | Nucleus |
"Little nucleus," Center of the nucleus | Nucleolus |
Tissue that covers the surface of the body or lines a body cavity, Forms most glands | Epithelial Tissue |
The functions of the epithelium (5) | Protection, Absorption, Secretion, Ion transport, Filtration |
Tissues with one layer of cells | Simple Tissues |
Tissues with more than one layer of cells | Stratified Tissues |
Tissues with cells that are wider than tall (plate-like) | Squamous |
Tissues with cells that are as wide as tall (cubes) | Cuboidal |
Tissues with cells that are taller than they are wide (pillar-like) | Columnar |
Ducts that carry proteins of exocrine glands to epithelial surface or to a body cavity | Exocrine Glands |
Ductless glands that secrete substances directly into the bloodstream, Produces hormones | Endocrine Glands |
