Explanation:
The cell wall of fungi is primarily composed of chitin, a tough, complex polysaccharide also known as fungal cellulose. This distinguishes them from plants, whose cell walls are made of cellulose, and bacteria, whose cell walls contain peptidoglycan. Chitin provides structural support and protection to fungal cells.

Explanation:
Vitamin B₆ (pyridoxine, pyridoxal, pyridoxamine) is a coenzyme (pyridoxal phosphate, PLP) for many enzymes involved in amino acid metabolism, including transaminases and decarboxylases. B₁ acts in carbohydrate metabolism, B₂ in redox reactions, B₁₂ in methylation and DNA synthesis.

Explanation:
Genes are specific sequences of nucleotides that serve as the fundamental units of heredity, and in all cellular organisms, they are made of DNA (deoxyribonucleic acid). Chromosomes are thread-like structures composed of DNA and proteins, and they are located within the nucleus of eukaryotic cells. DNA is the genetic material in all cellular organisms; RNA serves as the genetic material only in some viruses, not in cells. Thus, statements 1 and 2 are correct.
