QuestionAnswer
Cytoplasm The entire contents of the cell except the nucleus and bounded by the cell membrane.
Mitochondria Organelle in eukaryotic cells that serves as the site of cellular respiration to create ATP.
Nucleolus specialized structure in the nucleus where the assembly of ribosomes begins.
Chloroplast An organelle found only in plants and photosynthetic protists that absorbs sunlight and uses it to drive the synthesis of organic compounds from carbon dioxide and water.
Nucleus the chromosome containing organelle of a eukaryotic cell.
Endoplasmic Reticulum An extensive membranous network in eukaryotic cells, continuous with the outer nuclear membrane and composed of ribosome-studded rough and ribosome-free smooth regions.
Lysosome A membrane enclosed bag of hydrolytic enzymes for breaking things down it is found in the cytoplasm of eukaryotic cells.
Cell/Plasma Membrane The membrane at the boundary of every cell that acts as a selective barrier, regulating what enters and exits the cell.
Ribosome An organelle found in all cells that synthesise that create proteins it is found free floating in the cytoplasm or attached to the Rough E.R
Eukaryote Organisms whose cells contain membrane bound organelles and whose DNA is enclosed in a cell nucleus and is associated with proteins. Plants & animals have eukaryotic cells.
Prokaryote unicellular organism that lacks a membrane bound nucleus mitochondria or any other membrane bound organelle.
Organelle A specialized cellular part such as a nucleus mitochondria chloroplast or ribosome that has a specific function: little organ.
Centriole & Spindle Fibers Organelles found in animal cells. They’re made of cylinders of microtubules and aid during cell division. Centrioles produce spindle fibers. These protein structures pull chromosomes apart during cell division.
Cell wall A protective layer external to the plasma membrane in plant cells, bacteria, fungi, and some protists. In the case of plant cells, the wall is formed of cellulose fibers embedded in a polysaccharide protein matrix.
