Tissues
Forms protective sheets covering body surfaces and lining cavities, controlling passage of substances, and forming glands for secretion, absorption, and sensation.
What is epithelial tissue?
A series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids.
What is endoplasmic reticulum?
Phase where the chromosomes line up in the middle, or equator, of the cell (between the two poles).
What is metaphase?
Weak bonds that are formed between two atoms with slight charges on them.
What are hydrogen bonds?
Tissue that connects, supports, protects, and binds other tissues and organs, forming the body's framework and filling spaces between them.
What is connective tissue?
The cellular structures responsible for protein synthesis.
What are ribosomes?
Phase when the nuclear envelope reforms around the DNA.
What is telophase?
A strong chemical link where two nonmetal atoms share pairs of valence electrons.
What is a covalent bond?
Tissue in animals, composed of cells containing actin and myosin that contract to produce movement, maintain posture, and circulate fluids.
What is muscular tissue?
A series of flattened membranes that act like a post office for packages of proteins.
What are the Golgi Apparatus?
Meiosis I phase when homologous chromosomes pair up and exchange genetic information in a process called crossing over.
What is prophase I?
A bond between oppositely charged ions, formed by the complete transfer of one or more valence electrons from a metal atom to a nonmetal atom.
What is an ionic bond?
Tissue specialized for rapid communication, coordinating body functions by transmitting electrical signals.
What is nervous tissue?
A membranous, bean-shaped organelle that is the “energy transformer” of the cell,
What is the mitochondria?
Phase where sister chromatids are pulled apart, and move toward opposite poles (ends) of the cell.
What is anaphase?
A type of covalent bond where electrons are shared unequally between two atoms, creating a partial negative charge on the more electronegative atom and a partial positive charge on the other.
What is a polar covalent bond?
