Answer 1

For the above questions

Golgi Body - It is involved in the packaging of the protein molecules before they are sent to their destination. These organelles help in processing and packaging the macromolecules like proteins and lipids that are synthesized by the cell and hence act as the ‘post office’ of the cell.

Ribosome are made up of RNA and proteins, and each ribosome consists of two separate RNA-protein complexes, known as the small and large subunits, the ribosomess are responsible for protein synthesis. It helps in translation of mRNA molecule for protein synthesis in cytoplasm.

Rough ER is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum. This organelle is primarily concerned with the synthesis, folding and modification of proteins, especially those that need to be delivered to different organelles within the cell, or secreted from the cell.

Nucleolus is a round body located inside the nucleus of a eukaryotic cell. It makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes.

Plasma membrane is a double layer of lipids (phospholipid) that separates the cell interior from the outside environment, it allow certain substances to enter and leave a cell, and prevent some harmful materials from entering and some essential materials from leaving. In other words, plasma membranes are selectively permeable.

Smooth ER, is an organelle found in both animal cells and plant cells it make cellular products like hormones and lipids and various other substance needed for the cell. It also distributes those products throughout the cell and to places in the organism.

Hence accourding to the question

Ribosomes - 3. Translate the messages in mRNA into Protein.

Plasma Membrane - 2. Control of substance moving into and out of cell.

Rough ER - 4. Protein made here are often exported out of the cell.

Nucleolus - 6. Assemble Ribosomal(rRNA) subunits.

Smooth ER - 5. Site of Vesicle formation and synthesis of lipids occurs here.

Golgi Body - 1. Final modification of proteins and lipids.
