Document Summary

Archaea: prokaryotes that are members of the domain archaea (distantly related to the members of bacteria) Bacteria: prokaryotes that are members of the domain bacteria. Basal body: a structure derived from a centriole that produces a cilium or flagellum and anchors this structure within the plasma membrane. Cell wall: non-living, protective and supportive layer secreted outside the plasma membrane. Fluid-filled vacuole occupying most of the volume of many plant cells; performs several functions, including maintaining pressure. Chlorophyll: pigment found in chloroplasts that captures light energy during photosynthesis. Chloroplast: organelle in plant and plant-like protists that is the site of photosynthesis. Chromatin: the complex of dna and proteins that make up eukaryotic chromosomes. Chromosome: a dna double helix and associated proteins that help to organize and regulat the use of dna. Cilium: short hair-like, motile projection from the surface of certain eukaryotic cells that contains microtubules.
