Correct option is B)
Peroxisomes are found in photosynthetic cells and perform photorespiration. They also take part in lipid metabolism. Lysosomes are the cell's garbage disposal system and not the peroxisomes.
So, Statement 1 is correct and statement 2 is incorrect.

Read the given statements and select the correct option.Statement 1: P...
Peroxisomes
Statement 1: Peroxisomes are involved in photorespiration of the plant cells and help in the lipid metabolism of animal cells.
Statement 2: They are the cells' garbage disposal system.
Explanation:
Peroxisomes are small, membrane-bound organelles found in eukaryotic cells. They are involved in a variety of metabolic reactions, depending on the cell type.
Statement 1 is correct because:
- In plant cells, peroxisomes are involved in photorespiration, a process that occurs when plants close their stomata to conserve water. This leads to an accumulation of oxygen in the cell, which can be toxic. Peroxisomes contain the enzyme catalase, which helps to break down hydrogen peroxide, a toxic byproduct of photorespiration.
- In animal cells, peroxisomes are involved in the metabolism of lipids and the detoxification of harmful substances.
Statement 2 is also correct because:
- Peroxisomes are often referred to as the cell's garbage disposal system because they contain enzymes that break down and recycle various molecules, including fatty acids and amino acids. They also play a role in the breakdown of toxins, such as alcohol and formaldehyde.
Therefore, both statements are correct and statement 2 is the correct explanation of statement 1. Peroxisomes have multiple functions in different cell types, including photorespiration in plants and lipid metabolism and detoxification in animals. Additionally, they serve as the cell's garbage disposal system, breaking down and recycling various molecules.
