Cell wall is made of polysaccharide and amino acid in most of the members of
(a) Monera
(b) Protista
(c) Fungi
(d) Animalia

Options

A. Monera
B. Protista
C. Fungi
D. Animalia

Answer

To solve the question regarding which group of organisms has a cell wall made of polysaccharides and amino acids, we can analyze each option step by step:

### Step 1: Analyze Option (a) Monera
- Monera includes unicellular prokaryotic organisms, primarily bacteria.
- The cell wall of bacteria is primarily composed of peptidoglycan, which is a complex polysaccharide that also contains amino acids.
- Therefore, this option is a strong candidate.

### Step 2: Analyze Option (b) Protista
- Protista consists of a diverse group of mostly unicellular eukaryotic organisms.
- Some protists have cell walls made of cellulose or silica, but many do not have a cell wall at all.
- Since not all protists have a cell wall, this option does not fit the criteria.

### Step 3: Analyze Option (c) Fungi
- Fungi have a cell wall that primarily contains chitin, which is a polysaccharide.
- However, chitin does not contain amino acids in the same way that peptidoglycan does.
- Therefore, this option does not meet the requirement of having both polysaccharides and amino acids.

### Step 4: Analyze Option (d) Animalia
- Animals belong to the kingdom Animalia and are characterized by the absence of a cell wall.
- Since they do not have a cell wall, this option is not correct.

### Conclusion
After analyzing all the options, the only group of organisms whose cell wall is made of polysaccharides and amino acids is Monera. Therefore, the correct answer is:

**(a) Monera**
