Differentiate Secretary and invasive tapetum.
फरक स्पष्ट करा
उत्तर
- Secretory tapetum (parietal/glandular/ cellular): The tapetum retains the original position and cellular integrity and nourishes the developing microspores.
- Invasive tapetum (periplasmodial): The cells lose their inner tangential and radial walls and the protoplast of all tapetal cells coalesces to form a periplasmodium.
