Which among the following is incorrect about endoplasmic reticulum?

These are complex network of membrane bounded tubules They are classified as smooth and rough endoplasmic reticulum Smooth endoplasmic reticulum has ribosomes attached to their surface and acts as site of protein synthesis Rough endoplasmic reticulum is connected by nuclear membrane at one end and golgi apparatus on the other end

Which among the following is incorrect about prokaryotic cell?

In prokaryotic cell, cell compartmentalization is absent Genetic material is scattered in the nucleus Protista is an example of prokaryotic cell Prokaryotic cell has a cell membrane

Which among the following is incorrect about lysosomes?

These are membrane bound vesicles that contain digestive enzymes They are double membraned and are isolated from their neighboring environment The digestive enzymes present include proteases, lipases, nucleases, glycosidases and phosphatases The lysosomes defend against bacterial and viral infection

Which among the following is not correct about Golgi apparatus?

They are absent in RBCs, sperm cell of Pteridophytes and Bryophytes Golgi apparatus is freely distributed in animal cells and in plants fluid filled sac like structures called cisternae that pile parallel to each other to form Golgi bodies There are three main components, namely, cisternae, tubules and vesicles The membrane bound containers which appear dense in the cytoplasm are called vesicles

Which among the following is incorrect about vacuoles?

Vacuoles are fluid filled membrane bound sacs They consist of water and sap consisting of minerals, sugars, amino acids and proteins etc. The function of vacuoles differs from one organism to other Vacuoles in plants are not membrane bound and therefore they occupy most of the cell
