<h2>Development of Plant Needles</h2>
Explanation:
- Seed of pitch pine treated with colchicine delivered tetraploid seedlings which had thick and sporadic needles and less fortunate tallness and diameter growth than ordinary seedlings.
-
In test of colchicine-initiated polyploidy in pines, researcher found that a significant number of the polyploid plants returned to a diploid development in light of the fact that the polyploid cells partitioned at a more slow rate and were overwhelmed by the more quickly developing diploid cells which encompassed them.
-
The primary needles of both diploid and polyploid plants were more effective at low light intensity than secondary needles, and they had lower compensation points.
The first stage is TRANSCRIPTION, it is a process that takes place in the nucleus or in the cytosol, the DNA acts as a template to transcript it's information forming a new mARN molecule which contains the codons that codes an specific amino acid.
This mARN molecule will exit the nucleus and will be translated in the ribosomas that can be found in the cytosol or the Endoplasmic Reticulum. during TRANSLATION the mARN will be decoded to produce a polypeptide chain, this happens when the ribosome induces the binding of a tRNA anticodon sequences that are complementary to the mRNA codons, this will tell the ribosome which amino acid is needed to form the polypeptide chain.
It's important to clarify that in Prokaryotic cells, both of these stages take place in the cytosol since it doesn't have organelles binded by membrane unlike the Eukaryotic cells where the Transcription happens in the nucleus and the translation happens in the cytosol or endoplasmic reticulum
