Answer 1

The correct option is B Amoeboid or invasive type

Amoeboid or Invasive is also known as Periplasmodial Tapetum. It is the most common type of tapetum in the angiosperms. This type of tapetum can be seen in Alisma, Butomus, Tradescantia and Typha, etc. The tapetal cells fuse among themselves to make the tapetal periplasmodium. The protoplast of the fused tapetal cells then moves into the locule. This protoplast movement into the locule, may take place during meiotic prophase.

Thus the correct option is B.
