though. Much like an organ serves a specific function in an organism, such as an eye helps a fish see or a stamen helps a flower reproduce, organelles each have specific functions within cells. Cells are self-contained systems within their respective organisms, and the organelles ...
What cells have a nucleus and membrane bound organelles? What cell organelles are involved in cell division? 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...
The nucleus is the command center of the cell. It houses all genetic information — inherited from both parents in organisms that reproduce sexually — in long DNA strands called chromatids. This genetic information is expressed through the production of ribosomes, small organelles that produce spec...
In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a eukaryote. Some eukaryotes, like amoebae, are free-living, single-celled entities. Other eukaryotic cells are part of multicellular organisms. For instance, all plants and ...
