The cell organelle involved in forming complex sugars from simple sugars is:

How are chromatin,chromatid,and chromosomes related to each other?

Give examples of prokaryotic cells.

Match the following Column $A$ and Column $B$:

Column $A$	Column $B$
$(a)$ Smooth endoplasmic reticulum	$(i)$ Amoeba
$(b)$ Lysosome	$(ii)$ Nucleus
$(c)$ Nucleoid	$(iii)$ Bacteria
$(d)$ Food vacuoles	$(iv)$ Detoxification
$(e)$ Chromatin material and nucleolus	$(v)$ Suicidal bag

State the reason for the following:
$(i)$ Mitochondria are known as the powerhouse of the cell.
$(ii)$ Plastids are able to make their own protein.
$(iii)$ Plant cells shrink when kept in a hypertonic solution.

Why are lysosomes also known as 'scavengers of the cells'?
