Explanation:
The nucleus is considered as controlling centre of the cell. The parts of the nucleus includes nucleolus, nuclear pore, chromatin, and nuclear envelope. Nucleolus is the part of the nucleus which is present inside the cell and lacks a nuclear membrane and its function is producing and assembling of ribosomes.
The reason for not considering other statement as true are as follows:
1. Nucleolus is found only in Eukaryotas.
2. Nucleus is the control centre of the cell.

Answer:
Chitin, is the third layer of the cell wall of fungi.
Explanation:
As other living things, the cell wall is made by different compound, this allowed to protect and to pass some nutrients inside the cell.
The first layer is made by nanoproteins, these molecules provides structure and protection. The second one is made by glucans (some carbohidrates), that allows to carry some nutrients or wastes inside or outside the cell. The third one is made by chitin. Next to the cell wall it comes the cell membrane with their proteins and lipids.
