Answer 1

Answer:

1) answer - Lysosomes are known as suicide bags of the cell because they contain lytic enzymes capable of digesting cells and unwanted materials.

When lysosomes burst, the lytic enzymes within the organelle spill all over the cell, rupturing the cell membrane or cell wall and inducing the death of the cell.

2) answer- Proteins are produced in RER (Rough Endoplasmic Reticulum). Proteins are produced in the RER by the ribosomes attached to it.

Ribosomes are produced in cytoplasm and mitochondria’s chloroplast. RNA present in ribosomes plays a significant role in the synthesis of proteins. This synthesis is called translation as the protein compound is formed from amino acid and the amino acid structure is decoded from genes.

3)answer- The membrane that surrounds the organelles of the cell, by creating a barrier between cell organelles and the external environment is called the plasma membrane. It is also called a boundary of the cell
