Cell Theory a. all organisms are composed of cells b. the cell is the basic unit of life c. cells arise from pre-existing cells Unicellular organism with 1 cell (uni = 1) Multicellular organism with multiple specialized groups of cells Prokaryote no membrane-bound organelles (no nucleus)

Ribosomes structure-small made up of 2 sub-units protein and RNA -large ribosomes found it eukaryotic cells - smaller ribosomes found in prokaryotic cells, mitochondria and chloroplast. Ribosomes functionsite of protein synthesis cell-surface membraneall the molecules in the membrane arranged with the phospholipids bilayer create the partially permeable membrane components of membranesphospholipids, bilayer

Theory of EndosymbiosisEukaryotic cells emerged when mitochondria and chloroplasts, once free-living prokaryotes, took up permanent residence inside other larger cells, about 1.5 billion years ago. Eukaryotic CellA type of cell with a membrane-enclosed nucleus and membraneenclosed organelles. Organisms with eukaryotic cells (protists, plants, fungi, and animals) are called eukaryotes. Prokaryotic CellA type of cell lacking a membrane-enclosed nucleus and membraneenclosed organelles; fo...

MULTIPLE CHOICE 1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus, the nucleus should be observed. A single circular chromosome is characteristic of prokaryo...
