Cellulose is a polymer whose monomer is glucose. What is the difference between chromatin and a chromosome? Sets found in the same folder. Cell Structure Review - Image Diversity: centrioles. ► RETURN TO TOP OF PAGE. Most bacteria also have an outer cell wall made of peptidoglycans and other organic substances. What is the observed structure called? Cell structure review answer key lime. Similarities: lysosomes and peroxisomes are small membranous vesicles that contain enzymes and enclose residual substances of an internal or external origin to break them down. In young plant cells, many small vacuoles can be seen; within adult cells, the majority of the internal area of the cell is occupied by a central vacuole.
Some cells have cilia (paramecium, the bronchial ciliated epithelium, etc. ) Which type of cell evolved first, the eukaryotic cell or the prokaryotic cell? Even though cells can be very different, they are basically compartments surrounded by some type of membrane. Eukaryotic cells can be divided into three main parts: the cell membrane that physically separates the intracellular space from the outer space by enclosing the cell; the cytoplasm, the interior portion filled with cytosol (the aqueous fluid inside the cell); and the nucleus, the membrane-enclosed internal region that contains genetic material. Intermediate filaments are also made of protein. Cell structure and function test answer key. The cytoskeleton is a network of very small tubules and filaments distributed throughout the cytoplasm of eukaryotic cells. Which component of cell structure is contiguous to this membrane? In photosynthesis, solar energy is transformed into chemical energy, the energy of the chemical bonds of the produced glucose molecules (and of the molecular oxygen released). This hypothesis is called the endosymbiotic hypothesis of the origin of mitochondria. Cellular respiration is the process of using an organic molecule (mainly glucose) and oxygen to produce carbon dioxide and energy. Mitochondria are organelles enclosed by two lipid membranes.
It is presumed that mitochondria were primitive aerobic prokaryotes that were engaged in mutualism with primitive anaerobic eukaryotes, receiving protection from these organisms and providing them with energy in return. Cell structure review answer key of life. Plant cell walls are made of cellulose. ► NEXT STOP ON SITE TOUR. What are the main respective components of cell walls in bacteria, protists, fungi and plants? Cells have problems functioning when they get too big.
The main function of chloroplasts is photosynthesis: the production of highly energetic organic molecules (glucose) from carbon dioxide, water and light. The endosymbiotic theory can also be applied to chloroplasts. Cells can also connect to form larger structures. What substances make up the nucleolus? It is not enclosed by a membrane. Their genetic material is found in the cytosol. Plants have the wall; animals do not.
The latter is responsible for the absorption of the light photic energy used in photosynthesis. This observation led to the discovery of cells, a fact only possible after the invention of the microscope. Because cell membranes are fragile, in some types of cells, there are also external structures to support and protect the membrane, like the cellulose wall of plant cells and the chitin wall of some fungi cells. In mitochondria, the two last steps of cellular respiration take place: the Krebs cycle and the respiratory chain. The nuclear membrane is also called the karyotheca. Viruses are considered the only living organisms that do not have cells. What is being observed is the Golgi complex, or Golgi apparatus. Other sets by this creator.
What are the morphological, chemical and functional similarities and differences between lysosomes and peroxisomes? Ribosomes can be found unbound in the cytoplasm, attached to the outer side of the nuclear membrane or attached to the endoplasmic reticulum membrane that encloses the rough endoplasmic reticulum. What is the difference between a plasma membrane and a cell wall? Lipid membranes do not only form the outer layer of cells.
Regarding the presence of the nucleus, what is the difference between animal and bacterial cells? Are membranes only present as the outside of cells? The Endoplasmic Reticulum. There are many types of cells. The rough endoplasmic reticulum has a large number of ribosomes attached to the external side of its membrane. What are the three main parts of a eukaryotic cell? The main function of vacuoles is the osmotic balance of the intracellular space. In bacteria, the cell wall is made of peptidoglycans; among protists, algae have cell walls made of cellulose; in fungi, the cell wall is made of chitin (the same substance that makes the exoskeleton of arthropods); and in plants, the cell wall is also made of cellulose. Phospholipids are amphipathic molecules that are regularly organized in the membrane according to their polarity: two layers of phospholipids form the lipid bilayer, with the polar part of the phospholipids pointing to the exterior part of the layer and the non-polar phospholipid chains toward the interior. Are there living organisms without cells? What colors (of the electromagnetic spectrum) are absorbed by plants? The inner membrane invaginates to the interior of the organelle, forming the cristae that enclose the internal space known as the mitochondrial matrix, in which mitochondrial DNA (mtDNA), mitochondrial RNA (mt RNA), mitochondrial ribosomes and respiratory enzymes can be found. It forms an extensive net of channels throughout the cell and is classified into rough or smooth types. The most accepted hypothesis claims that the simpler cell, the prokaryotic cell, appeared earlier in evolution than the more complex eukaryotic cell.
Millikan examined a fine spray of spherical oil droplets falling through air; the drops had picked up an electric charge as they were sprayed through an atomizer. What is the name of the membrane that encloses the nucleus? Cells hold a variety of pieces and each cell type has a different purpose. What are mitochondria? Plants also have organelles such as the green chloroplast or large, water-filled vacuoles. They do not have membranes, cell organelles, or own metabolism. This problem illustrates the ideas behind the Millikan oil drop experiment-the first measurement of the electron charge. Find the radius R of a drop in terms of, the densities of the oil and of air and, and the viscosity of air.
You don't find single cells that are as large as a cow. These molecules are found in the internal membranes of chloroplasts. Prokaryotic cells are those that do not have an enclosed nucleus. This appears to be a paradox: green light is not important for photosynthesis. What substance are plant cell walls made of? This is an interesting problem of biological evolution. What chemical substances compose the plasma membrane? Or flagella (flagellate protists, sperm cells, etc. Students also viewed. Inside the Cell (Canadian Museum of Nature Video). Cells are unique to each type of organism.
Within the organelle, DNA, RNA ribosomes and also the pigment chlorophyll are present. What are the main structures within the nucleus of a cell? The vesicles detach from the Golgi apparatus, travel across the cytoplasm and fuse with the plasma membrane, secreting their substances to the exterior. What is the plasma membrane of the cell? Green is reflected and such reflection is the reason for that characteristic color of plants. This fluid contains proteins, enzymes and other important substances for nuclear metabolism. What path is followed by the energy absorbed by plants to be used in photosynthesis? There are smaller pieces that make up cells such as macromolecules and organelles. To which other cellular organelles can the hypothesis also be applied? There is a difference between the optimum color frequency for the two main types of chlorophyll, chlorophyll A and the chlorophyll B. Chlorophyll A has an absorption peak at a wavelength of approximately 420 nm (indigo) and chlorophyll B has its major absorption at a wavelength of 450 nm (blue).
