what is the structure of chlorophyll

The mitochondrion is a double-membraned, rod-shaped structure found in both plant and animal cell. … The outer membrane covers the surface of the mitochondrion and has a large number of special proteins known as porins. It is freely permeable to ions, nutrient molecules, energy molecules like the ADP and ATP molecules.

What’s the structure and function of mitochondria?

A mitochondrion is a round to oval-shaped organelle found in the cells of almost all eukaryotic organisms. It produces energy, known as ATP, for the cell through a series of chemical reactions.

What is structure of nucleus?

The nucleus is composed of various structures namely nuclear envelope, nucleoplasm or nucleus sap nuclear matrix, chromatin and nucleolus. The nuclear membrane forms an envelope like structure around the nuclear contents and is commonly known as a nuclear envelope.

What structure represents a chloroplast in the cell?

In plants, chloroplast-containing cells exist in the mesophyll. Chloroplasts are surrounded by a double membrane similar to the double membrane found within a mitochondrion. Within the chloroplast is a third membrane that forms stacked, disc-shaped structures called thylakoids.
