What does a red blood cell have that a bacterium cell does not? What cells does the vascular cambium produce? What is the cell membrane also called? Which organelles comprise the endomembrane system of a cell? What do amacrine cells do?
Which organelles do eukaryotic cells have that prokaryotic cells do not have? What does the nucleus do in a cell? What cells contain a nucleus and membrane-bound organelles? Which organelle makes the proteins that are needed by the cell?
Prokaryotic cellsmake only a limited number of proteins and have no compelling need for the endomembrane system of eukaryotes, which is necessary to process proteins manufactured in the cell. Organelles Organelles are elements inside a cell that possess a double plasma membrane like the one surroundin...
What Other Components Do Cells Have? As previously mentioned, a cell's cytoplasm is home to numerous functional and structural elements. These elements exist in the form of molecules and organelles — picture them as the tools, appliances, and inner rooms of the cell. Major classes of intracell...
What are the two major differences between prokaryotic and eukaryotic cells? The main difference between the two types of cell is thatprokaryotic cells have no (membrane-bound) organelles. This means that the processes that usually happen in organelles take place in the cytoplasm. The DNA in prok...
Which cell has no nucleus? Prokaryotesare organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have...
Organelles are small subcellular structures located in the cytoplasm of eukaryotic and prokaryotic cells, and in more complex eukaryotic cells, organelles are often enclosed by their own membrane. Each organelle performs a specialised function for that cell, much like an organ does for the body. ...
Organelles and the Nucleus: Organelles are subcellular structures that perform a variety of functions including (but certainly not limited to) protein and lipid synthesis, respiration (as seen in animal cells), and photosynthesis (as seen in plant cells). Most of these functions however depend on...
What organelles work with the nucleus? What separates the nucleus from the cytoplasm? What cell part directs all cell activities? What is the function of a nucleus in an amoeba? Why do cells perform mitosis? What functions do centrosomes have during mitosis? What function does cell division ...
This one is perhaps the most misinterpreted postulate. Organelles like the nucleus, ribosomes and many more are present inside the cell; they are smaller in size, but vital for the existence of life. If that’s the case, shouldn’t they be the basic unit of life? Well, that’s not th...
