- a rope-like assemblies of fibrous polypeptides in the cytoskeleton that provide support and strength to cells; A component of the cytoskeleton that includes all filaments intermediate in size between microtubules and microfilaments.
- b A membrane-enclosed sac occupying most of the interior of a mature plant cell, having diverse roles in reproduction, growth, and development.
- c strong wall outside a plant cell's plasma membrane that protects the cell and maintains its shape
- d A coiled, spiral-shaped bacterium that has endoflagella and flexes as it moves.
- e A stacked portion of the thylakoid membrane in the chloroplast; functions in the light reactions of photosynthesis.
5 Multiple choice questions
- organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis)
- organelle that controls all the activities of a cell and contains hereditary material made of DNA
- an area within a chloroplast that lies between the thylakoid membranes; serves as the site of the Calvin cycle in photosynthesis which involves the synthesis of carbohydrates
- ratio of a cell's outside area to its internal volume
- A sticky layer that surrounds the cell walls of some bacteria, protecting the cell surface and sometimes helping to glue the cell to surfaces.
5 True/False questions
nuclear pore → opening in the nuclear envelope that permits the passage of proteins into the nucleus and ribosomal subunits out of the nucleus
coccus → any spherical or nearly spherical bacteria
secretion → a functionally specialized substance (especially one that is not a waste) released from a gland or cell by exocytosis
chromatin → The complex of DNA and proteins that makes up a eukaryotic chromosome. When the cell is not dividing, it exists as a mass of very long, thin fibers that are not visible with a light microscope.
plasma membrane → fingerlike projections that create wavelike currents(peristalsis) in fluid surrounding the ovary to move the ovum into the uterine tube; Filamentous proteins on the surface of bacterial cells
