Here's why:
* Ribosomes are the sites of protein synthesis in all living cells. They translate genetic information from messenger RNA (mRNA) into proteins.
* Green plants are eukaryotic cells, meaning they have membrane-bound organelles, including ribosomes.
* Bacteria are prokaryotic cells, which lack a nucleus and other membrane-bound organelles. However, they still possess ribosomes, though their structure is slightly different from eukaryotic ribosomes.
While both green plants and bacteria have ribosomes, other structures like chloroplasts (for photosynthesis) are only found in green plants, and cell walls (made of peptidoglycan) are typically found in bacteria.
