Great question. Chloroplasts (likemitochondria) have their own DNA. Way back inevolutionary time, some bacteria developed a kind ofpartnership with other cells, which we calleukaryotic.

You are watching: Which is the smallest unit of life that can survive and reproduce on its own?

The chloroplasts have the right to dophotosynthesis, using light energy,CO2, and also water to do sugar because that thehost cell. The hold cell offers protection andraw products for the chloroplast. Together you saidthe hold cell also provides proteins necessary by thechloroplasts. Yes sir a nice site around this at:

supposedly there room some chloroplasts that canlive outside of cells. Over there are also somespecies that sea cheese that can hold top top thechloroplasts from the birds that castle eat and getsugar from these “orphaned” chloroplasts. Thechloroplasts carry out not reproduce, though.

Chloroplasts seem to it is in dependent top top the hostcells for reproduction, yet your idea of figuringout which protein (or various other molecules) castle needfrom the organize is great. You’re really thinkinglike a scientist.

If those proteins might be conveniently synthesizedwithout host cells, it might be possible to usesolar power to make a lot much more sugar. Often,though, we discover that organisms deserve to synthesizethings much much more efficiently than we have the right to producethem without using organisms.

Why would certainly you suppose the eukaryotic cells ofthe sea slug no to provide the special proteinsthat chloroplasts need?

You can want to look right into a job in cellbiology.

thanks for askingAnswer 2:

An important component of the definition of a cell isthat that is the smallest unit of life that canreplicate. Though, the doesn’t typical you can’tmake individual materials of a cell. Forinstance, you have the right to make DNA in a test tube withjust the proteins and other molecules required forDNA reproduction. The interesting thing aboutchloroplasts is the they were when photosyntheticbacteria that lived by themselves.

The concept is that the ancestor of a plantcell tried to eat a bacterium, however decided insteadto permit it become a brand-new organelle so that it couldget energy from the sun. This idea is urged bythe fact that the chloroplast has its own separateDNA native the plant cell. However, over time, thisbacterium has end up being so dependence on the plantcell and vice-versa that it can’t endure orreproduce on its own. Therefore in that feeling thechloroplast couldn’t reproduce outside the cell.Though to answer her question much more directly, theprocesses forced to give birth a chloroplastic arenot just the amount of your parts. Thereproduction that a chloroplast needs a number ofinterconnected processes arranged in certaincompartments in the cell at specific times. Theconstruction that a brand-new chloroplast doesn’t justrequire the details component protein encoded inthe nucleus; it calls for a bunch of other helperproteins, molecules, and also organelles such together themitochondria to develop the energy for theassembly processes. Ultimately, thereproduction of a cell individual parts is ahighly complex process that would most likely require aliving system, such as the cell itself, tocomplete.

Answer 3:

The cell has many complex and connected processgoing ~ above at all times. It wouldn"t yes, really bepossible to incorporate every one of these in a testtube. Come create an ext chloroplasts, a cabinet needsthe protein that consist of the chloroplast, thehelper proteins that assemble it, and ATP to powerall these proteins. If every one of these to be present,it is feasible that the chloroplast can makeitself in a check tube. To mine knowledge, however, Idon"t think this has actually been done, probably becausewe don"t know every vital protein yet.

Answer 4:

You are best that cholorplasts requireproteins encoded by the cell core to duty anddivide. Chloroplast department is somewhat of amystery… researchers have determined a handful ofnucleus-encoded genes that are most likely to beinvolved in chloroplasts division. When thesegenes room mutated, chloroplastic number and also size isaltered. As far as I deserve to find, no one hasactually watched a chloroplast divide in realtime. Maybe if us knew all of the proteinsrequired for chloroplast division, we might putthem in a systems with chloroplasts and watch thechloroplasts divide. Wouldn"t the be cool! Ihope you execute this amazing in vitro experimentsome day.
