Ubisch bodies are present in

Options

A. Pollen tube
B. Pollen grain
C. Microspore
D. Tapetum

Answer

**Step-by-Step Solution:**

1. **Understanding Ubisch Bodies**: Ubisch bodies are acellular structures that play a crucial role in the formation of sporopollenin, which is a key component of the outer layer of pollen grains.

2. **Location of Ubisch Bodies**: Ubisch bodies are specifically found in the tapetum, which is a layer of cells surrounding the developing pollen grains in the anther of flowering plants.

3. **Function of the Tapetum**: The tapetum provides nutrition to the developing pollen grains and is involved in the synthesis of sporopollenin, which is essential for the formation of the pollen grain's outer layer.

4. **Clarifying Misconceptions**: While Ubisch bodies are associated with pollen grains, they are not present in the pollen tube or the pollen grain itself. Instead, they are found in the tapetum cells, which contribute to the formation of the pollen.

5. **Conclusion**: Therefore, the correct answer to the question "Ubisch bodies are present in" is the tapetum.
