Based on the organization of their cellular structures, all living cells can be divided into two groups. cellular groups Eukaryotic Cells, Eukaryotic Cells cellular characteristic Eukaryotic cells may have flagella or cilia. Flagella and cilia consist of a distinct arrangement of sliding microtubules surrounded by a membrane. The microtubule arrangement is referred to as a 2X9+2 arrangement., Eukaryotic cells are generally much larger and more structurally complex than prokaryotic. reason The larger a cell, the smaller is its surface-to-volume ratio; A small surface-to-volume ratio means nutrients cannot rapidly diffuse to all interior parts of the cell. That is why eukaryotic cells require a variety of specialized internal organelles to carry out metabolism, provide energy, and transport chemicals throughout the cell., Eukaryotic Cells cellular characteristic The cytoplasmic membrane is a fluid phospholipid bilayer containing sterols. The membrane is capable of endocytosis and exocytosis., Eukaryotic Cells cellular characteristic The ribosomes are composed of a 60S and a 40S subunit that come together during protein synthesis to form an 80S ribosome., Eukaryotic Cells description Eukaryotic cells are generally much larger and more structurally complex than prokaryotic., Prokaryotic Cells cellular characteristic Internal membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, vacuoles, and lysosomes are absent., Eukaryotic Cells cellular characteristic Chloroplasts serve as organelles for photosynthesis., Prokaryotic Cells cellular characteristic Many prokaryotes have flagella, each composed of a single, rotating fibril and usually not surrounded by a membrane. There are no cilia., Eukaryotic Cells cellular characteristic The nucleus divides by mitosis. Haploid (1N) sex cells in diploid or 2N organisms are produced through meiosis., Eukaryotic Cells cellular characteristic The nuclear body is bounded by a nuclear membrane, contains one or more paired, linear chromosomes, has nucleoli, and is called a nucleus., Prokaryotic Cells examples Prokaryotic cells include the domain Bacteriaand the domain Archae., Prokaryotic Cells cellular characteristic The nuclear body is not bounded by a nuclear membrane, contains one circular chromosome, has no nucleoli, and is called a nucleoid., Eukaryotic Cells examples Eukaryotic cells belong to the domain Eukarya and include animals, plants, algae, protozoans, and fungi., Eukaryotic Cells cellular characteristic Internal membrane-bound organelles such as mitochondria, endoplasmic reticulum, the Golgi apparatus, vacuoles, and lysosomes are present, Prokaryotic Cells cellular characteristic The cell usually divides by binary fission. There is no mitosis. Prokaryotic cells are haploid so meiosis is not needed., Prokaryotic Cells cellular characteristic The electron transport system is located in the cytoplasmic membrane. It contributes to the production of ATP molecules via chemiosmosis., The cell is the basic unit of life. Based on the organization of their cellular structures, all living cells can be divided into two groups. cellular groups Prokaryotic Cells, Prokaryotic Cells cellular characteristic There are no chloroplasts. Photosynthesis usually takes place in infoldings or extensions derived from the cytoplasmic membrane., Prokaryotic Cells cellular characteristic With few exceptions, members of the domain Bacteria have cell walls composed of peptidoglycan. Members of the domain Archae have cell walls composed of protein, a complex carbohydrate, or unique molecules resembling but not the same as peptidoglycan.
