Question

Name three organelle and their function.

Answer 1

Plasma Membrane

The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell.

Nucleus

Some of the main components of the nucleus include the chromatic, nucleoplasm/nuclear sap and the nucleolus.

In eukaryotic cells, the nucleus is enclosed in a nuclear membrane. It is the organelle that controls the hereditary traits of an organism by directing such processes as protein synthesis and cell division among others.

For prokaryotes, the DNA lacks a nuclear membrane. The genetic material is therefore bound in the nucleotide region.

The nucleolus plays an important role in ribosome production.

Ribosome

Ribosomes are tiny organelles that contain RNA and specific proteins within the cytoplasm. Within the cell, ribosomes are directly involved in the manufacture of proteins by using their RNA and amino acids.

This process involves decoding the information contained in the mRNA and using amino acids to produce the required proteins.

Answer 2

Explanation:

plasma membrane is the organelle that encapsulates the contents of the cell,

Mitochondria are some of the largest organelles within a cell, and

Plastids are a type of organelle found in plant cells and algae. Like mitochondria, plastids are membrane-bound organelles that contain nucleoids. As such, they are also semi-autonomous organelles.
