QuestionAnswer
this part of the cell surrounds the cell, controls what enters/leaves the cell. double layer of phospholipid molecules tightly pack togheter. cell membrane / plasma
small structure located close to the nuclear membrane centriole
contains digestive enzymes to help phagocytes to digest bacteria and is responsible for autolysis of cells after their death lysosome
gel-like substance that surrounds all organelles outside the nucleus. contains enzymes that speed up (catalyze) biochemical reactions in the cell cytoplasm
contains the genetic material, deoxyribonucleic acid (DNA). DNA is organized into genes on chromosomes that controls protein synthesis nucleus
system of tubes and sacs studded with ribosomes on the external surface. Ribosomes are involved in the manufacture of membrane-bound proteins smooth ER
barrier separating the nuclear contents from the cytoplasm. facilitates and regulate the exchange of materials between the nucleus and the cytoplasm nuclear membrane
responsible for manufacturing proteins. some unattached in cytoplasm but more commonly attached to the surface of rough ER ribosomes
small organelle with a minor function facilitating transport in and out of cells (endocytosis and exocytosis) vacuole
flattened sacs that package proteins and carbohydrates into vesicles for export from the cell Golgi apparatus
cell's "powerhouse" because it produces energy in the form of adenosine triphosphate (ATP), which provides energy for muscle contraction, active transport and to build large molecules mitochondrion

the system that acts as the body's chemical control center endocrine
one of this body system's vital functions lymphatic
the science of body structure anatomy
the study of body function physiology
"powerhouses" of the cell because they produce energy in the form of ATP mitochondria
genetic material (DNA) is found in which organelle? nucleus
structures within cells that perform cellular functions organelles
this cellular organelle is responsible for digesting exhausted cell components lysosome
study of cells cytology
study of tissues histology
blood is a what type of tissue? connective
a gland is a type of single specialized epithelial cell adapted for what? secretion endocrine-hormones into circulation exocrine-into ducts or directly onto a free surface
