Which cellular organelles replicate in the G1 phase of the cell cycle?
Organelles such as the mitochondria and the chloroplasts replicated in the G1 phase of the cell cycle. This is so that when the cell divides, no parts are lost.
What organelles possess small ribosomes and circular DNA?
Mitochondria and chloroplasts possess small ribosomes and circular DNA. These organelles are believed to have originated from bacterial ancestors that were engulfed by early eukaryotic cells through endosymbiosis.
Which two organelles are used as evidence supporting enosymbiotic theory?
The mitochondria and chloroplasts are used as evidence supporting the endosymbiotic theory. Both organelles have their own circular DNA, replicate independently of the cell, and have a double membrane structure similar to certain prokaryotes.
What are autonomous cell organlles?
these are the mitochondria and chloroplasts and it is because they have their own DNA, mRNA, tRNA, ribosomes and they replicate by binary fission so they are said to be self governing. Semi autonomous means they want to leave but they are in a symbiotic relationship with the cell and have evolved to become part of it.
Do viruses have organelles?
No, viruses do not have organelles because they are not considered living organisms. They are made up of genetic material enclosed in a protein coat and rely on host cells to replicate. Viruses lack the cellular structures and functions that define living organisms.
What are the cellular organelles that can self replicate?
Mitochondria
Phase of cell cycle when the organelles and chromosome replicate?
Interphase
What is an organism whose organelles are used by a virus to replicate?
Host.
Which cellular organelles replicate in the G1 phase of the cell cycle?
Organelles such as the mitochondria and the chloroplasts replicated in the G1 phase of the cell cycle. This is so that when the cell divides, no parts are lost.
What Organelles divide by fission?
Organelles that divide by fission include mitochondria and chloroplasts. Both of these organelles are thought to have originated from ancestral prokaryotic cells and retain the ability to replicate independently of the cell cycle. This process of division is similar to binary fission observed in bacteria, allowing them to grow and multiply within the eukaryotic cell. Additionally, some peroxisomes can also replicate by fission.
What organelles are present in red blood cells?
Red blood cells are considered cells, but they lack all organelles. Red blood cells cannot divide or replicate like other cells of the body.
What organelles possess small ribosomes and circular DNA?
Mitochondria and chloroplasts possess small ribosomes and circular DNA. These organelles are believed to have originated from bacterial ancestors that were engulfed by early eukaryotic cells through endosymbiosis.
Why are organelles non living?
Organelles are considered non-living because they do not exhibit all the characteristics of a living organism on their own. While organelles may have specific functions within a cell, they lack the ability to replicate independently, respond to stimuli, and carry out metabolic processes on their own. Organelles require the coordination of the entire cell in order to function and survive.
Which two organelles are used as evidence supporting enosymbiotic theory?
The mitochondria and chloroplasts are used as evidence supporting the endosymbiotic theory. Both organelles have their own circular DNA, replicate independently of the cell, and have a double membrane structure similar to certain prokaryotes.
What compares the replication of mitochondria to the replication of organelles that do not have their own DNA?
Mitochondria replicate independently through a process similar to binary fission, similar to bacterial division, due to their own circular DNA. In contrast, organelles without their own DNA, like the endoplasmic reticulum or Golgi apparatus, rely on the cell's overall growth and division processes for replication. While mitochondria can self-replicate in response to cellular energy demands, other organelles are synthesized and assembled through the cell's machinery, demonstrating distinct mechanisms of replication and regulation.
What part of the cell divides first during cell division?
The first stage of mitosis is known as interphase. During this phases, chromosomes and organelles replicate and get rid for cell division.
What happens to all organelles during mitosis Do they duplicate also?
During mitosis, organelles typically do not duplicate in the same way that chromosomes do. Instead, they are distributed between the two daughter cells. Some organelles, like the mitochondria and endoplasmic reticulum, may replicate prior to mitosis to ensure each daughter cell has the necessary components for function. However, the exact distribution and replication process can vary among different organelles.
