Chapter 2 The Cell Flashcards
Adipose
Fat tissues
ATP
Chemical compound that provides energy used by body cells
Areolar
A type of connective tissue consisting of fibers and a variety of cells embedded in a loose matrix of soft sticky gel
Centriole
One pair of tiny cylinders in centrosomes of a cell; believed to be involved with the spindle fibers formed during mitosis
Chromatin
Staining substance in the nucleus ; divides into chromosomes during mitosis
Collagen
Principles organic constituent of connective tissue
Columnar
Shape in which cells are higher than they are wide
Cuboidal
Cell shape resembling a cube
Cytoplasm
A gel like substance of a cell exclusive of the nucleus and the other organelles
DNA
Deoxyribose nucleic acid
Hypertonic
A solution containing a higher level of salt than is found in a living red blood cell
Hypotonic
A solution containing a lower level of salt than is found in a living red blood cell
Interphase
He phase immediately before the visible stages of a cell division when DNA of each chromosome replicated itself
Mitosis
Indirect cell division involving complex changes on nucleus
Organelle
Cell organ, for example the ribosome
RNA
Ribose nucleic acid
Squamous
Scale like
Transcription
When double stranded DNA molecules unwind and form mRNA
Dialysis
Separation of smaller particles from larger particles through a semipermeable membrane
Diffusion
Spreading ; for example scattering of dissolved particles
Osmosis
Movement of a fluid through a semipermeable membrane
Phagocytosis
Ingestion and digestion of articles by a cell
Pinocytosis
The active transport mechanism used to transfer fluids or dissolved substances into cells
Filtration
Movement of water and small solute particles but not larger particles through filtration membrane
High concentration ———> low pressure area
