What organelles are cellular structures were common to all the different organisms looked at with the microscope? What are cells that have no defined nucleus or other organelles called? What are the major organelles in a cell? What are their functions?
Which cells are the most unspecialized mass of cells? What do plant cells have that animal cells do not? What are two types of cell categories found in nervous tissue? What are their roles? The powerhouse of a cell in living organisms is called what?
Other eukaryotic cells are part of multicellular organisms. For instance, all plants and animals are made of eukaryotic cells — sometimes even trillions of them (Figure 4). Figure 4: Comparing basic eukaryotic and prokaryotic differences A eukaryotic cell (left) has membrane-enclosed DNA, which ...
Do big organisms like elephants and redwood trees have larger cells than small organisms like ants and moss? Or do they just have MORE cells? What limits the size of most cells? Briefly describe the main difference between a prokaryotic cell and...
Many researchers today believe that the first cells or unicellularprokaryoticorganisms did not arise from any precursor cell. They were formed from a biological force still unknown to the human race today. Though highly disputed, this theory still violates the cell theory. Mitochondria and chloroplasts...
Scientists divide cellular life into two major groups, prokaryotes and eukaryotes. Eukaryotes tend to be more complex organisms than prokaryotes, which are bacteria and a similar group called archaea. Ribosomes are present in all cells, and are part of the machinery that assembles proteins inside ...
Organisms categorized within the domain Archaea have prokaryotic cells, but are unlike bacteria in that they never have peptidoglycan in their cell walls, their cell membranes contain lipids of unique composition (glycerol molecules are mirror images of those found in other cells, and form ether ...
All complex, multicellular organisms are similar in the fact that they are made up of many different types of cells that have specific roles and... Learn more about this topic: Multicellular Organisms | Definition, Pictures & Examples from ...
And modENCODE is doing the same thing for model organisms.One of the surprising things that ENCODE has revealed is that transcription is not confined to the previously defined coding sequences. It turns out that transcription also occurs in intergenic sequences, and transcripts have been found ...
Are prokaryotes and eukaryotes a type of cell? What are examples of organisms that contain prokaryotic cells? What is intercellular cytoplasmic communication? How do plant cells elongate? What's the purpose of genes in the cell? Why do we only use some genes in some cells?
