A) idioblast
B) phragmoblast
C) blastomere
D) none of these
Correct Answer: A
Solution :
Idicblasts are stellate calcium oxalate crystals usually found in the aerenchyma of aquatic plants to give support to the tissue. When the parenchyma cells in the cortex possess well developed air spaces such tissue is known as aerenchyma. Blastomeres are the cells resulting from early cleavage of the ovum. The zygote is transformed from a single cell to a solid mass of cells called the morula which bears blastomeres.
