(about 10x larger than prokaryotic cells; DNA is enclosed in a nuclear membrane) Bacterial cells: -have all characteristics of life -lack membrane bound organelles
Prokaryotes divide by binary fission, eukaryotes tend to divide by mitosis. TRUE 3.TRUE or FALSE? A chain of rods would be called a Streptobacillus TRUE 4.TRUE or FALSE? A capsuleis a highly organized type of glycocalyx. TRUE 5.TRUE or FALSE? Biofilms may be life-threatening to both patients who have cystic fibrosis and those that are catheterized.

cytology Eukaryotic- Cell Membrane: -mosaic composed of large molecules of proteins and phospholipids (fats) -regulates the passage of nutrients, waste products and secretions in or out of the cell - selectively permeable Eukaryotic- Nucleus -"command center": controls functions of entire cell -nucleoplasm: gelatinous material in nucleus
Solution : Nuclear membrane is not found in prokaryotic cell.
Explanation: Prokaryotic cells differ from eukaryotic cells in that they lack any membrane-bound organelles, including a nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.
The cytoplasm, plasma membrane, nucleoid, and ribosomes are found in all bacterial cells. Capsules, fimbriae, pili, flagella, and even the cell wall are not found in all bacteria.
Hence, the correct answer is 'One one chromosome located in the nucleus'.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not.
Hence, the correct answer is 'Nuclear membrane'.
Cell wall is only found in plant cells and not in any other cells. Option A is correct.
Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do.
Prokaryotic- Flagella: -thread-like, protein appendages that enable bacteria to move . -motile bacteria usually possess flagella, never cilia . -monotrichos: single flagella. -amphitrichous: one or more at each end . -lophotrichous: lot at one end . -peritrichous: all over entire surface .
metabolism; which is all of the chemical reactions that occur within a cell. Eukaryotes : -more complex, has true nucleus, & many membrane bound organelles. -includes algae, protozoa, fungi, plants, animals, and humans. (about 10x larger than prokaryotic cells; DNA is enclosed in a nuclear membrane) Bacterial cells:
Bacterial cells: -have all characteristics of life . -lack membrane bound organelles . -includes cells of archaea & bacteria kingdoms (part of prokaryotes) Viruses: -not cells at all (not prokaryotic or eukaryotic) -depend on energy and metabolic machinery of a host cell to reproduce.
spirochetes may have two flagella-like fibrils known as axial filaments. Pili (fimbriae) -hair-like structures mostly in gram-negative bacteria, composed of polymerized protein called pilin, thinner than flagella & not associated w/ motility. Two types.
Eukaryotic- Cell Membrane: -mosaic composed of large molecules of proteins and phospholipids (fats) . -regulates the passage of nutrients, waste products and secretions in or out of the cell . - selectively permeable. Eukaryotic- Nucleus. -"command center": controls functions of entire cell .
Eukaryotic- Cytoskeleton: -present through cytoplasm. -serve to strengthen, support, and give cell shape (also important for cell division and motility) .
-the length of time it takes for one bacterial cell to split into two cells is referred to as the organism's generation time. (which varies from 10 mins to hours)
