Transcript of cells
a large, membrane-bound space within a plant cell that is filled with fluid. Most plant cells have a single vacuole that takes up much of the cell. It helps maintain the shape of the cell. The jellylike material outside the cell nucleus a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus the membrane that surrounds the nucleus. an organelle within the nucleus spherical body containing many organelles, including the nucleolus. nucleus a process in which plants convert sunlight, water, and carbon dioxide into food energy small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis. ribosome a vast system of interconnected, membranous, infolded and convoluted sacks that are located in the cell's cytoplasm a vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell's cytoplasm part of the chloroplasts in plant cells, located within the inner membrane of chloroplasts, between the grana.
disk-shaped membrane structures in chloroplasts that contain chlorophyll. •nucleus
•The endoplasmic reticulum
•lysosomes lyosomes are one of the thing animals cells have that plant cells normally wont have animal cells have cilia wich is very rare in plant cells humans have animal cells similarities of all cells bacteria has bean on earth for millions of years,however scientist didnt discover bacteria until the 1600 when they discovered it they did'nt purposely discover them a scientist named Anton van Leeuwenhoek he first found bacteria when he was looking at scraping from his teeth bacteria cells are prokaryotic witch means that the cell does not contain a nucleus. bacteria cells usually come in three different shapes and form one is a rod like shape finally theres the spherical form ,the next is a spiral like form and Most bacteria cells have a cell wall. The cell wall is rigid and provides protection for the bacteria cell. Some bacteria cells have flagella (or many flagella) or tiny whip-like structures that help them move Bacteria are living things that have only one cell Many are helpful. Bacteria are also used in making healthy foods like yogurt and cheese. Most bacteria won't hurt you - less than 1 percent makes people sick. viruses are NOT liveing thing's bacteria ARE liveing things Like all other life, they fit the criteria: life must: use energy grows and develops. Reproduce responds to surroundings. Without a host cell, viruses cannot carry out their life-sustaining functions or reproduce. viruses lack ribosomes witch is why they need a host so that they can feed of there energy All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Viruses are generally classified by the organisms they infect, animals, plants, or bacteria. Since viruses cannot penetrate plant cell walls, virtually all plant viruses are transmitted by insects or other organisms that feed on plants. there are two forms viruses come in one is a rod shape ,then there the sphere form The virus responsible for HIV was first isolated in 1983 by Robert Gallo of the United States and French scientist Luc Montagnier similarities both bacteria and viruses can couse disease neither the viruse or the bacteria have a nucleus all cells are microscopic this is not found in the animal cell, it acts as a fence all cells can be both good and bad these cells arent very much alike in all four becouse of the virus cell being soo diffrent and nonlivein similarities between animal,plant,bacteria they all have ribosomes all three cells are liveing they can all reproduce victor lozoya
