Final answer:
The genome in plants includes the DNA found in the chromosomes in the nucleus, as well as the DNA in the mitochondria and chloroplasts.
Step-by-step explanation:
The statement is True.
In plants, the genome includes the DNA found on the chromosomes in the nucleus, as well as the DNA in the mitochondria and chloroplasts. This means that the genetic material in plants is not only located in the nucleus, but also in the mitochondria and chloroplasts.
The DNA in the mitochondria and chloroplasts is important because it contains genes that are responsible for the functioning and structure of these organelles. For example, the mitochondrial genome encodes proteins that are involved in energy production through oxidative phosphorylation.
The statement True correctly answers the student's question regarding plant genomes. In plants, the genome consists of not only the DNA contained in the chromosomes within the cell's nucleus but also incorporates DNA found in the mitochondria and the chloroplasts. This extrachromosomal DNA is essential to the unique functions of these organelles, with mitochondrial DNA being critical in energy production and chloroplast DNA playing a key role in photosynthesis. The presence of this DNA supports the endosymbiotic theory, which posits that mitochondria and chloroplasts originated as prokaryotic cells that entered into a symbiotic relationship with the ancestors of modern-day eukaryotic cells.
