| Question | Answer |
|---|---|
| an open channel through the cell wall that connects the cytoplasm of adjacent plant cells, allowing water, small solutes, and some larger molecules to pass between the cells | plasmodesmata |
| a microscope that passes electron beam through very thin sections stained with metal atoms and is primarily used to study the internal ultrastructure lf cells | transmission electron microscope (TEM) |
| a membranous sac in the cytoplasm of a eukaryotic cell | vesicle |
| a type of intercellular junction in animal cells that functions as a rivet, fastening cells | desmosomes |
| a membrane-bounded vesicle whose specialized function varies in different kids of cells | vacuole |
| In a eukaryotic cell, the double membrane that surrounds the nucleus, perforated with pores that regulate traffic with the cytoplasm. The outer membrane is continuous with the endoplasmic reticulum | nuclear envelope |
| a type of cell with membrane-enclosed nucleus and membrane-enclosed organelles, Organisms with eukaryotic cell (protest, fungi, and animals) are called eukaryotes | eukaryotic cell |
| a type of intercellular junction between animal cells that prevents the leakage of material through the space between cells | tight junction |
| an organelle in eukaryotic cells that serves as the site of cellular respiration; uses oxygen to break down organic molecules and synthesize ATP | mitochondria |
| the portion of the ER that is free of ribosomes | smooth ER |
| a microscope that uses and electron beam to scan the surface of the sample, coated with metal atoms, to study details of its topography | scanning electro microscope (SEM) |
| a type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles. Organsims with prokaryotic cells (bacteria and archaea) are called prokaryotic | prokaryotic cell |
| an infolding of the inner membrane of a mitochondrion. The inner membrane houses electron transport chains and molecule of the enzyme catalyzing the synthesis of ATP | cristae |
| The complex of DNA and proteins that makes up eukaryotic chromosomes. When the cells is not dividing, chromatin exists in its dispersed form, as a mass of very long, thin fibers that are visible with a light microscope | chromatin |
| a netlike array of protein filaments that lines the inner surface of the nuclear envelope and helps maintain the shape of the nucleus | nuclear lamina |
| The compartment of the mitochondrion enclosed by the inner membrane and containing enzymes and substrates for the citric acid cycle, as well as ribosomes and DNA | mitochondrial matrix |
