Is it possible today for a eukaryotic cell to live without mitochondria or chloroplasts?
No, eukaryotic cells cannot live without mitochondria and chloroplasts
; they provide the energy cells need to survive.
Is it possible today for a eukaryotic cell to live without?
Explanation:
It is not possible today
for a eukaryotic cell to live without mitochondria or chloroplasts since these are the organelles responsible for providing the energy cells need to survive. Mitochondria are the organelles that synthesize energy in cells.
What happens if there is no mitochondria in eukaryotic cell?
Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only
be able to obtain energy from anaerobic respiration
(in the absence of oxygen), a process much less efficient than aerobic respiration.
Do eukaryotic cells need mitochondria?
Eukaryotes Without Mitochondria
In contrast to the prokaryotes, eukaryotes have a more complex layout, including membrane-bound organelles like mitochondria. Most eukaryotes have mitochondria, while every multi-cellular eukaryote does. However, a few one-celled eukaryotes lack mitochondria.
Can a eukaryotic cell live without mitochondria?
“We now know that
eukaryotes can live happily without any remnant of the mitochondria
.” Mitochondria are the descendants of bacteria that settled down inside primordial eukaryotic cells, eventually becoming the power plants for their new hosts.
Can mitochondria survive on its own?
They may fuse together. They move around inside the cell by interactions with the cytoskeleton. However,
mitochondria cannot survive outside the cell
. … Mitochondria divide independently by a process that resembles binary fission in prokaryotes.
Can yeast survive without mitochondria?
Mitochondrial DNA (mtDNA) is a compulsory genetic component for encoding essential respiratory enzymes in all eukaryotic cells. However, some yeast species (called rho positive)
could survive without mtDNA under conditions of fermentation
(a metabolic pathway alternative to respiration).
Is Monocercomonoides a life form?
Monocercomonoides isn’t a living fossil
, a holdout from the days of the earliest eukaryotes, Karnkowska notes. Its closest relatives still have small mitochondria, suggesting that it jettisoned the organelles fairly recently in evolutionary terms.
Which statement is true of prokaryotic and eukaryotic cells?
Which is true of prokaryotic and eukaryotic cells?
Prokaryotic cells are larger than eukaryotic cells. Eukaryotic cells do not have nuclei
, and prokaryotic cells do have nuclei. Prokaryotic cells lack membrane-bound organelles, and eukaryotic cells contain membrane-bound organelles.
Which cell structure are seen in prokaryotic and eukaryotic cells?
Cell walls and plasma membranes
are found in both bacteria (prokaryotes) and plants (eukaryotes). Ribosomes are not bound by a membrane, and are mainly composed of rRNA; they are used for protein synthesis in both prokaryotes and eukaryotes.
Which cells do not have mitochondria?
As the only cell which does not contain or have the mitochondria is
the red blood cell
. Red blood cell does not contain organelles like nucleus and mitochondria.
What happen when cell has no mitochondria?
Without mitochondria modern cells would
die for lack of an adequate energy supply
. The energy is created by a proton gradient that acts like a pump to rotate structures to produce and release adenosine triphosphate (ATP). … So if mitochondria absent there is no source of energy and cell organelles stop their function.
What would happen if mitochondria stopped working?
For our bodies the conversion from food energy to ATP happens in mitochondria. If your mitochondria are not working properly then
you are less able to convert food into ATP
. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.
Why are there no mitochondria in prokaryotes?
Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus; instead
their genetic material is free-floating within the cell
. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria.
Where is RNA found in eukaryotic cells?
In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into
the cytoplasm
, where ribosomes translate the RNA into protein.
Is the powerhouse of cell?
The mitochondria
, often labeled the powerhouse of the cell, are the organelle responsible for energy production within the cell. Playing an important role in cellular respiration, the mitochondria are the main location for ATP production.
