Why Cells that carry on digestion within the cell do not partly digest themselves because they secrete their digestive enzymes into membrane-enclosed?
Cells that carry out digestion internally, such as lysosomes, contain digestive enzymes that are enclosed within membrane-bound compartments. This membrane prevents the enzymes from coming into contact with the cell's own structures, thereby protecting the cell from self-digestion. Additionally, the acidic environment inside lysosomes is optimized for enzyme activity, ensuring that they effectively break down substrates without harming the cell itself. This compartmentalization is crucial for maintaining cellular integrity and function.
What are the structures that contain digestive enzymes to digest and destroy old cells?
Lysosomes. Lysosomes are membrane-bound organelles found in eukaryotic cells. Their main purpose is to break down polysaccharides into monosaccharides and proteins into amino acids or other substances suitable for incorporation into the cell's metabolism. Lysosomes originate in the Golgi complex, and are often responsible for the death of its host cell. When cells get old (around 9 years) the membrane surrounding the lysosomes weakens and eventually ruptures, releasing its deadly potent digestive enzymes into the cell. These enzymes wreak havoc, destroying the cell from the inside out. However, because of this, when a cell dies, all that is left is, virtually, a stockpile of nutrients and building blocks for the next generation of cells.
Which cell part is involved in animal cell but not in plsnt cell?
The cell part involved in animal cells but not in plant cells is the lysosome. Lysosomes contain digestive enzymes that break down waste materials and cellular debris. While plant cells have their own mechanisms for waste processing, such as vacuoles, they do not contain lysosomes. Additionally, animal cells have centrioles, which are involved in cell division, and are typically absent in plant cells.
Which orgelles contain enzymes that break down old cell parts?
Lysosomes are vesicles (vesicles= small, spherical, single-membrane sacs used for temporary storage and transport within a cell and are classified by their contents) that contain digestive enzymes. In the process of autophagy, lysosomes digest worn-out organelles within cells. In the process autolysis, damaged or extra cells are digested and broken down by their own lysosomes. "Biology is your life, you know."
What is the most importance of a cell enclosing its digestive enzymes?
Digestive enzymes are in an enclosed organelle so that materials not meant to be digested, aren't. If they were released in the cytoplasm then anything could be digested, resulting in the cell dying.
What is the importance of a cell enclosing it's digestive enzymes inside lysosomes?
If a cell organisation is disturbed , lysosomes break down and digest their own cells so as to stop other reactions harmful body.
Why are lysosomes called suicide bags?
because it can burst itself and distroy the cell if the cell gets damaged.
What is the source of cell autolysis?
Cell autolysis, or self-digestion of a cell by its own enzymes, can be triggered by a variety of factors such as cellular stress, infections, or genetic mutations. It can also occur as part of programmed cell death processes, like apoptosis or autophagy, where the cell actively breaks down its components for recycling.
What is autodigestion?
Autodigestion is the process where a cell's own enzymes break down cellular components, leading to cell damage or death. This can occur when lysosomes, which contain powerful digestive enzymes, rupture within the cell. Autodigestion is associated with certain diseases, such as pancreatitis.
What is the two organelles that contain their own genetic material?
Mitochondria and chloroplasts. The question asks for organelles with their OWN genetic material. The material from the nucleus already belongs to the cell. Those two evolved from symbiotic prokaryotes and maintain their own DNA.
What contains digestive chemicals used to destroy worn out cell parts and to help clean up the cell?
Lysosomes are vesicles (vesicles= small, spherical, single-membrane sacs used for temporary storage and transport within a cell and are classified by their contents) that contain digestive enzymes. In the process of autophagy, lysosomes digest worn-out organelles within cells. In the process autolysis, damaged or extra cells are digested and broken down by their own lysosomes. "Biology is your life, you know."
How do lysosomes work?
vacuoles basically have the same functions as vesicles therefore, in plant cells, when lysosomes are fused with the vacuole, the contents within the vacuole are digested by lysosomes' hydrolytic enzymes into the simpler subunits. Remember that vacuoles not only store H2O, sugar and salt, but also pigments and toxic molecules. The digested contents are now simpler molecules that are released into the cytoplasm. Also, normal rejuvination occurs when parts of a cell are digested within its own lysosomes (autodigestion).

How does the lysosome reproduce?
Lysosomes do not have the ability to reproduce on their own as they are organelles within a cell. They are produced by the endoplasmic reticulum and Golgi apparatus, and are recycled through autophagy and endocytosis processes.
What enters a cell and becomes part of cell's hereditary material without destroying the cell or replicating itself?
A virus can enter a cell and integrate its genetic material into the cell's own DNA without destroying the cell or replicating itself. This integration can lead to long-term effects on the cell's behavior and potentially alter the cell's hereditary material.
