Why are enzymes important to cells? Why do cellular organelles have different structures? Why are ribosomes important to cells? Why is centrosome absent in plant cells? Explain why nearly all cells make some proteins. Why is programmed cell death important?
What are germ cells? What organelles are found in epithelial cells? What do B-cells make when they recognize antigens? What cells clean and digest debris entering the alveoli? What 4 things do all cells have? Does the mucous membrane have goblet cells?
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. ... Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis. The cytoplasm isall the contents of the cell inside the cell membrane, not including the nucleus. Where is the c...
Female Student: Actually, well, if it doesn't have organelles, I mean DNA or whatever. Then what happens if the lens is damaged or something? Professor: And that's the problem, the price of clear vision of transparent lenses is that the lens fibers can't regenerate or repair themselves,...
These different structures found within cells are called organelles.The endoplasmic reticulum is an organelle that can be found in botheukaryoticandprokaryoticcells.Just keep in mind that not all cells have endoplasmic reticulum! For example, red blood cells don’t have endoplasmic reticuli, even thou...
Eukaryotic Cells UseFlagella to Move Inside and Outside Organisms. Eukaryotic cells with a nucleus and organelles are found in higher plants and animals but also as single-celled organisms. Eukaryotic flagella are used by primitive cells to move around, but they can be found in advanced animals ...
The individual parts of a cell are responsible for a wide range of protective, reproductive, synthetic, metabolic and transportation functions. All cells have a membrane, DNA, ribosomes and cytoplasm; eukaryotic cells also include organelles, such as the
Other organelles found in fungal cells include mitochondria (energy-producing organelles), which vary in size, form, and number; vacuoles, which serve to store water, nutrients, wastes, or enzymes such as nucleases, phosphatases, or proteases; and plastids, which contain pigments and enzymes and ...
These organelles originated more than a billion years ago as single-celled organisms that were swallowed by larger cells. Since then the mitochondrial genome has shrunk, with many genes migrating to the cell nucleus. But that makes it all the more puzzling that mitochondria have retained any ...
Cell Structures and Organelles DNA and RNA Quantitation Gram Staining Nucleus Answer Yes, all bacteria have plasmids. Plasmids are a small, circular, double-stranded DNA molecule that naturally exist in all bacterial cells. Every bacterial cell has its own plasmid which is separated from chromosomal...
