What does nucleus contain?

In eukaryotic cells, the nucleus is an organelle. The majority of the cell's genetic material is contained within its totally encased nuclear membrane. Chromosomes are formed from this material, which is structured as DNA molecules and a variety of proteins.

Explanation:

When looking at an image of a cell, the nucleus is one of the most visible elements. The nucleus is located at the center of the cell and houses all of the cell's chromosomes, which encode genetic material. As a result, protecting this portion of the cell is extremely critical. The nucleus is surrounded by a membrane that keeps all of the chromosomes within and distinguishes between the chromosomes and the various organelles and components of the cell that remain outside. Because RNA needs to travel between the nucleus and the cytoplasm on occasion, holes in the nuclear membrane allow molecules to enter and exit the nucleus. The nuclear membrane was previously considered to only enable molecules to leave the nucleus, but it has since been shown that there is an active process for bringing molecules into the nucleus as well.

It contains the cell's genetical material.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
