What else can I help you with?
What organelle does waist exit cell?
The organelle responsible for expelling waste from the cell is the lysosome. Lysosomes contain enzymes that break down waste materials and cellular debris. Once the waste is processed, it can be expelled from the cell through exocytosis, where vesicles containing the waste fuse with the cell membrane to release their contents outside.
What is the Difference between organelle and the organ?
Organ is a fully differentiated structural and functuional unit in an animal that is specialized for some particular functionwhereas organelle ia a specialized part of a cell; analogous to an organ.
What organelle may survive and reproduce independently of a cell?
Mitochondria are organelles that were once free-living bacteria. They can survive and reproduce independently in certain conditions, suggesting they have retained some autonomy from the host cell.
Which cell organelles are thought to have once been independent bacteria-like cells?
it is ribinspons and gaint manolis
How do you enzymes reach the part of the cell in which they are needed?
Enzymes are typically produced in specific organelles within the cell, such as the cytoplasm or the endoplasmic reticulum. They are then transported to their target location within the cell through vesicles or the endomembrane system. Once at the desired location, enzymes can either act within that organelle or be secreted outside the cell.
Which organelle represents an exception to the cell theory because it contains genetic material and can reproduce within the cell?
Mitochondria are an exception to the cell theory because they contain their own DNA, can replicate independently of the cell, and have their own ribosomes to make proteins. This suggests that mitochondria have a separate evolutionary origin from the rest of the cell and may have once been free-living organisms that were engulfed by a host cell.
Which organelle would go next once proteins have been assembled?
bottom
Why there is a DNA in the mitochondria?
The consensus is that the mitochondria was once a free living single cell prokaryote that was engulfed and perhaps enslaved, perhaps joined as a symbiont with a burgeoning eukaryote cell type. Thus, this organelle kept some of it's own DNA. Google the endosymbiotic theory by Lynn Margulis.
What Substances targeted for export from the cell are modified and packaged in the .?
Substances targeted for export from the cell are modified and packaged in the Golgi apparatus. This organelle processes proteins and lipids synthesized in the endoplasmic reticulum, adding necessary modifications such as glycosylation. Once modified, the substances are sorted and packaged into vesicles for transport to their destinations outside the cell or to other organelles.
Weight lost at death?
There was once a question on the weight of a soul and the thought was to be able to measure how much a person weighed before death and after. Snopes has a decent article on this if you're interested. http://www.snopes.com/religion/soulweight.asp
Mitochondria existed on its own outside the cell?
Mitochondria have their own DNA separate and distinct from the cells DNA. It is believed that mitochondria were once separate from cells and have since developed a symbiotic relationship with them.
What parts of a cell do scientists think were once free-living organisms?
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
