Choose the correct answer: prokaryotic cells, eukaryotic cells, living organisms, bacteria. Cell structure ideas about cell a cell consists of three parts: the cell membrane, the nucleus every cell in the body is enclosed by a cell membrane. This lesson is on cells with a nucleus and membrane bound organelles in this lesson, we'll go over what these cells are called and define the. A membrane-enclosed sac of hydrolytic enzymes found in the cytoplasm of animal cells and some protists centriole a structure in the centrosome of an animal cell composed of a cylinder of microtubule triples arranged in a 9 + 0 pattern. The cell membrane of this class contains no pure cellulose, but a modification called fungus cellulose scientific american supplement, no 623, december 10, 1887 various a cell consists of a mass of protoplasm, generally enclosed in a cell membrane, and containing a nucleus and nucleolus. Nucleus and nucleoid are the areas which separate the genetic material from other cellular components of the cell nucleus is the membrane-enclosed area which houses the eukaryotic genetic material it consists of organized dna/protein molecules inside chromatin fibers. Membrane-enclosed vesicles form packages for cargo so that they may quickly and efficiently reach their destinations in this way, membranes divide the cell into specialized compartments, each carrying out a specific function inside the cell.
Quiz note: it is recommended that you save your response as you complete each question question 1 (mandatory) (1 point) a _____ cell contains a membrane-enclosed nucleus and membrane-enclosed organelles. The nucleus is known as the information storage organelle it is enclosed by a double membrane- nuclear envelope inside of the nucleus there is dna. The nucleus is enveloped by a double layered membrane, known as the nuclear membrane a clear fluid called nucleoplasm or karyolymph is enclosed in the membrane there is a network of fine thread-like matter, called the chromatin network, which contains the dna molecules and histones arranged in a particular manner. A double-layered membrane, the nuclear envelope, separates the contents of the nucleus from the cellular cytoplasm the envelope is riddled with holes called nuclear pores that allow specific types and sizes of molecules to pass back and forth between the nucleus and the cytoplasm. A because both plant and animal cells contain a membrane-enclosed nucleus that stores genetic information for the cell prokaryotic cells are either plant nor animal, the answer is a :.

Bacteria bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts. Cell biology/print version nucleusthey have genetic material but that material is not enclosed within a membrane membrane enclosing the nucleus.
A membrane bound organelle that is responsible for degrading proteins and membranes in the cell, and also helps degrade materials ingested by the cell vacuoles membrane surrounded bags that contain water and storage materials in plants. Membrane enclosed spaces allow cell functions to be compartmentalized and isolated from other functions prokaryotes lack membrane enclosed spaces in their cytoplasm some prokaryotes are photosynthetic the biochemical machinery for trapping light energy is contained within a highly folded plasma membrane.
The nucleus of a eukaryotic cell contains the dna, the genetic material of the cell the dna contains the information necessary for constructing the cell and directing the multitude of synthesis tasks performed by the cell in the process of life and reproduction the nuclear envelope surrounds the nucleus with a double membrane with multiple. Nucleus: the chromosome-containing organelle of a eukaryotic cell passive transport: the diffusion of a substance across a biological membrane peptidoglycan: a type of polymer in bacterial cell walls consisting of modified sugars cross-linked by. The plasma membrane is a lipid bilayer they were thought to have no internal structures enclosed by as well as the nucleus-like structures of the. The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes which surrounds the nucleus.
