the host cell must provide protection that is shelter to the mitochondria form external harsh environmental conditions and must provide it the external precursors required to start the synthesis of its own ATP that is pyruvate in case of many eukaryotic cells.

What is the process whereby the mitochondria and chloroplasts of protists arise?

The process whereby mitochondria and chloroplasts in protists arise is through endosymbiosis, where an ancestral eukaryotic cell engulfed a prokaryotic cell (which evolved into a mitochondria or chloroplast) forming a symbiotic relationship. Over time, these organelles integrated into the host cell and developed a mutually beneficial relationship, providing energy and photosynthetic capabilities to the host cell.


Do mitochondria make their own food?

Not really. Mitochondria use their DNA to produce many proteins and enzymes required for their function but not all. That makes the idea that they make their own food a little fuzzy. They can't live outside the cell that they are in, since they need some things from the 'host' cell.


Do parasites have mitochondria?

Virus and bacteria do not have.Other eukaryotic paracites have


What process caused chloroplast and mitochondria to evolve?

Chloroplasts and mitochondria are believed to have originated from a process called endosymbiosis, where a eukaryotic cell engulfed a photosynthetic bacterium (for chloroplasts) and a respiratory bacterium (for mitochondria). Over time, these bacteria developed a symbiotic relationship with the host cell, eventually evolving into the organelles we see today. This process provided the host cell with energetic advantages, leading to their evolutionary success.


Could an organism survive without its mitochondria if all the other organelles were present?

Primordial bacteria have no organelles. They represent the stage of evolution before organelles were acquired. Organelles (probably) began as infectious bacteria invading ameoba-like cells. If the host didn't kill them off and they didn't kill the host then the bacteria become a sort of parasitic organelle. These can be removed without too much harm to the host. In fact the host would probably benefit by their removal. If the parasitic bacteria them started to provide some service to the host cell then the host benefits from their presence. If the service they provide duplicates some basic process of the host then the host will 'forget' how to do the service itself and rely solely on its (now) symbiotic organelles. This is a very common facet of living things: if you don't use a certain ability then you lose it. Removal of the organelles at this stage would be fatal to the host.

Which cell organelles provide strong evidence for endosymbiotic origination?

Chloroplasts and mitochondria provide strong evidence for endosymbiotic origination. Both have their own DNA, double membranes, and replicate independently of the cell, indicating they were once free-living prokaryotic organisms that were engulfed by a host cell in the past.


Why a mitochondria are considered a antique bacteria?

It has its own DNA completely separate from the DNA of the host cell.


How did mitochondria and chloroplasts most likely arise in eukaryotic cells?

Mitochondria and chloroplasts most likely arose in eukaryotic cells through a process called endosymbiosis, where a host cell engulfed a prokaryotic cell. Over time, the prokaryotic cell evolved to become an organelle within the host cell, forming a symbiotic relationship. This theory is supported by the similarities between mitochondria and chloroplasts and modern-day bacteria.


Does food or other digested material have an effect on mitochondria and DNA?

Almost all eukaryotic organism have two types of Genetic material. Genomic DNA and mitochondrial DNA. Mitochondria itself a seperate bacteria, in evolution they are engulfed by the host cell. Mitochondria provides(synthesis) the energy needed by host cell. In turn, the host cell protects the mitochondria from the environmental hazards. The relationship is symbiotic in nature. If we ate food or antibiotics which affects the bacteria, there is a chance that will affects the mictochondrial DNA too.

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.


What is the Capture hypothesis?

The Capture hypothesis proposes that organelles such as mitochondria and chloroplasts were derived from free-living prokaryotes that were engulfed by a host cell but not digested. Over time, these engulfed prokaryotes established a symbiotic relationship with the host cell, eventually becoming permanent residents within the cell. This theory is supported by the presence of prokaryotic-like features in mitochondria and chloroplasts, as well as their own genetic material.


Does the largest circular structure represent a host cell?

Yes, the largest circular structure represents a eukaryotic host cell, which contains various organelles such as the nucleus, mitochondria, and endoplasmic reticulum. These organelles play vital roles in the cell's functions and maintenance.
