Answer:
The rough endoplasmic reticulum
Explanation:
The rough endoplasmic reticulum (ER) is an organelle that has the main function of producing proteins for the cell.
Antibodies are a type of protein, so they are made by the ER.
Since the immune cell can rapidly produce antibodies, it must have a significant amount of rough ER to make the proteins.

The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun.

Answer:
See the answer below
Explanation:
<em>The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.</em>
The problem of transporting the messenger RNA is solved by two features of the cell:
- The presence of pores in the nuclear envelop
- The presence of transport proteins in the nucleus
<u>The mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP. </u>
