ANSWER

a) The endomembrane system includes the nuclear membrane, the endoplasmic reticulum, the Golgi apparatus, lysosomes, vesicles, endosomes and cell membrane.

b) The endoplasmic reticulum (smooth and rough) is an interconnected network of flattened, membrane-enclosed sacs or tube-like structure which is responsible for the synthesis of lipids and steroid hormones (SER) and proteins (RER).

c) Ribosomes are known as protein factories because they are the main site of protein synthesis and are composed of ribonucleic acids and proteins.

d) The mitochondria is a double-membraned cell organelle, known as the powerhouse of the cell and the site of the electron transport chain (aerobic respiration) and oxidative phosphorylation (production of ATP molecules).

So, the correct answer is 'b, c and d'.
