5 Multiple Choice Questions
- The collection of membranes inside and around a eukaryotic cell, related either through direct physical contact or by the transfer of membranous vesicles; includes the smooth and rough endoplasmic reticulum, the Golgi apparatus, lysosomes, and vacuoles.
- region of cytoplasmic material that in animal cells contains structures called centrioles
- a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum), involved in the transport of materials.
- one of the small bodies that are found in the cytoplasm of a cell and that are specialized to perform a specific function
- unstructured semifluid substance that fills the space between cells in connective tissues or inside organelles, the surface area exposed to fluids, such as where the production of energy takes place, in a mitochondrion
5 True/False Questions
cell → A short cellular appendage specialized for locomotion, formed from a core of nine outer doublet microtubules and two inner single microtubules ensheathed in an extension of plasma membrane.
chloroplast → organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis)
glycocalyx → A layer of exopolysaccharide fibers on the surface of bacterial cells which may be involved in adherence to a surface. Sometimes a general term for a bacterial capsules; if compact called capsule and if diffuse, called slime layer
cell envelope → in a prokaryotic cell, the portion composed of the plasma membrane, the cell wall and the gycocalyx
cytoplasm → the region of a cell located inside the cell membrane (in prokaryotes) or between the cell membrane and nucleus (in eukaryotes); contains a gel-like material and cell organelles
