The correct answer is (4) Autotrophic organism.

Green plants make their own food by the process of photosynthesis using sunlight. Most of the autotrophs use carbon dioxide, sunlight and carbon dioxide to produce glucose that is used by the plants to obtain energy. Most of the oxygen comes from these organisms and decrease in the number of green plants can lead to several problems due to decrease in the amount of oxygen. Example: green plants, algae, and even some bacteria. This food and oxygen is produced by the action of autotrophic organisms

DNA is found in the nucleus of eukaryotic cells and the ribosomes, the location where proteins are made, are found out in the cy
Reika [66]

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>
