Answer:
endosymbiosis
Explanation:
The theory of endosymbiosis states that mitochondria in cells are once the descendants of aerobic prokaryotes. These prokaryotes used oxygen in order to generate energy. The mitochondria and the chloroplast are among the most important organelles that support endosymbiosis.

<span>It's a single celled </span>organism<span> with </span>cell walls but no nucleus or organelles
Answer:
1. nucleus- formation of ribosomal subunit
2. cytoplasm- attachment of amino acid to tRNA.
3. free ribosomes- cytoplasmic protein synthesis
4. chromatin- transcription and RNA processing
5. ribosomes: secretory protein synthesis
Explanation:
The nucleolus is the place in the nucleus where the ribosomal proteins enter and combine to form two ribosomal subunits. Therefore ribosomes are formed in the nucleus.
In the cytoplasm, free ribosomes are present which synthesize cytoplasmic protein and in the cytoplasm, amino acids attach to tRNA molecules and make aminoacyl tRNA which helps in making protein during translation.
Chromatin which is less condensed are transcribed in the nucleus into mRNA and this mRNA goes through RNA processing for mature mRNA.
Ribosomes are also attached with RER which is responsible for the production of secretory proteins that moves out of the cell.
