Section 1

Question Answer
organismcomplex, living being composed of structures that have a specific function in the whole
cellsthe smallest structures of the body
tissuesformed by grouped together cells
organsformed from different types of tissues
organ systemswhen organs work together
atomsthe smallest particles of an element
moleculessmallest amount of a substance
microscopicso small it can only be seen with microscope
ovumfemale’s egg
epithelialskin cells


Question Answer
plasma membranecell membrane that serves as the outer boundary of a cell
nucleuslocated in center of cell, acts as the command and control center
cytoplasmthe material that forms the cell
organellesspecialized parts of cells with important functions
endoplasmic reticulumconnects the parts of the cell, functions in transportation and storage


Question Answer
cell divisionthe process by which new cells are made
daughter cellsduring cell division the contents of a cells is divided between these cells
meiosisa process of cell division involved in reproduction
chromosomesstructures within the cell’s nucleus that contain your genes
genescells within your chromosomes that contain DNA
DNAgenetic blueprint that determines how an individual looks and functions
gametessex cells containing the 46 chromosomes
zygotesingle cell that is the combination of an egg and sperm
mitosisthe process through which the zygote eventually becomes a baby
embryothe result of a zygote undergoing mitosis
fetusthe end result of a developed embryo


Question Answer
phases of mitosisinterphase, prophase, metaphase, anaphase, and telophase
interphaseresting stage of mitosis, cell is not going through active division
replicationmaking an exact copy of the DNA molecules in the chromosomes
centriolesorganelles responsible for dividing the cell
prophasefirst part of active division, pair of centrioles separate, cytoplasm forms between them, nuclear membrane dissolves
nucleolusthe center of the nucleus
chromatidone of two strands that comprise the chromosomes
metaphasethird state of mitosis, nuclear membrane dissolves completely and the chromatids line up
anaphaseshortest phase of mitotic process, chromatids separate and move to opposite ends of the cell, each strand is a chromosome
telophasefinal phase of mitosis, chromosomes arrive at each end of cell, new nuclear membranes form around them, once cytoplasm forms around each one, this phase is finished


Question Answer
electrolytessalts and minerals that control fluid balance in the body
diffusionthe movement of molecules from an area of higher concentration to an area of lower concentration
osmosisthe process by which cells become isotonic
filtrationforcing water molecules and small particles through a membrane, whereas larger particles don’t pass through
passive transportprocess of cells moving particles across the membrane, does not require input of energy (eg. diffusion, osmosis, filtration)
active transportprocess of cells moving particles across the membrane, requires input of energy (eg. pinocytosis, phagocytosis)
adenosine triphosphate (ATP)the energy used in active transport, supplied by cell metabolism
pinocytosisprocess in which the cell takes in liquid outside the cell by making a small crater in the cell membrane
phagocytosisprocess in which the cell engulfs a large particle
cytoskeletonthe skeleton of cells


Question Answer
specializationprocess occurring in early embryo development where cells develop a certain look and function
tumor and neoplasmindicate abnormal and uncontrolled growth of cells
benign tumorsdo not result in death, growth is confined to one area
lipomatumor of fat cells, benign
nodulebenign tumor in thyroid gland
malignant tumorsresult in serious illness or death, cells divide and multiply at the expense of normal, healthy cells
metastasiswhen malignant tumors (cancer) send cells into distant sites of the body

Section 2

Question Answer
epithelial, muscle, connective, nervetissue types
epithelial tissuecovers the inner and outer surfaces of the body (ie. skin)
squamous epithelial cellsform the outer layer of skin
columnar epithelial cellsform the lining of the digestive tract and respiratory tract
cubodial epithelial cellsform the tissue that protects the kidney tubules and covers ovaries
endocrine gland cellsform a kind of epithelial tissues that secretes its products directly into the bloodstream (eg. thyroid gland)
exocrine gland cellssecretes its products into a compartment of the body outside of the bloodstream (eg. sweat)
striated muscle tissuecomposes skeletal muscles which are under voluntary control (eg. walking)
smooth muscle tissuecomposes skeletal muscles which are under involuntary control from the nervous system (ex. intestines propel food along)
cardiac muscle tissueinvoluntary tissue found only in the heart
connective tissueconnects or supports other body structures (eg. fat, cartilage, bone, blood, scars)
fasciaconnective tissue that forms a membrane to invest or surround muscles or organs to separate and support them
cartilagerubbery, smooth material that lines the surface of joints
adiopose tissuea form of connective tissue that can also provide energy in the form of lipid molecules
bloodtransports nutrients and wastes to and from cells
lymphinterstitial fluid that has been filtered by lymph vessels
nerve tissueextends throughout the body to carry messages to and from the brain, coordinating functions of the entire body
nerve cell or neuronfundamental unit of nervous tissue, conducts signals from one end of the cell to another (eg. pain, smell, sight, sound, taste)


Question Answer
scardense mat of fibrous material that appears after normal tissue is damaged (ie. response to injury)
membranesformed when two thin layers of tissue join together
epithelial and connectivetwo major classifications of membranes
mucous membranetype of epithelial membrane lining the digestive tract, respiratory passages and genitourinary tract
serous membranespleural, pericardial, peritoneal
pleural membranesline the pleural cavity, produces fluid to lubricate the expansion and contraction of lungs
pleuritisinflammation of the pleura
parietal pleural membranetype of epithelial membrane lining the inside of the rib cage
visceral pleural membranetype of epithelial membrane lining the outside of the lungs
pericardial membranetype of epithelial membrane lining the heart
peritoneal membranesline the abdominal cavity
parietal peritoneal membranestype of epithelial membrane lining the inner surface of the peritoneal cavity
visceral peritoneal membranestype of epithelial membrane lining the outer surfaces of the stomach and intestines
peritonitisinflammation of the peritoneal cavity
parietalrelating to the walls of a cavity
visceralrelating to an organ
synovial membranes and meningestwo types of connective membranes
synovial membranesline the cavities of joints the move freely (eg. shoulders, elbows, knees, fingers)
