Partially independent sporophyte is found in
(a) Pteris
(b) Funaria
(c) Dryopteris
(d) Selaginella

Options

A. Pteris
B. Funaria
C. Dryopteris
D. Selaginella.

Answer

To determine which of the given options has a partially independent sporophyte, let's analyze each option step by step.

### Step 1: Understand the Concept of Partially Independent Sporophyte
A partially independent sporophyte is one that does not completely depend on the gametophyte for its sustenance. It can perform some functions independently, such as photosynthesis or nutrient absorption, but still relies on the gametophyte for certain essential needs.

### Step 2: Analyze Each Option
- **(a) Pteris**: Pteris is a type of fern. In ferns, the sporophyte is typically dominant and independent, but it does not exhibit partial dependence on the gametophyte. Therefore, this option is not correct.

- **(b) Funaria**: Funaria is a moss. In mosses, the sporophyte is attached to the gametophyte and is dependent on it for water and nutrients. However, it can perform some functions independently, making it a partially independent sporophyte. This option is a strong candidate.

- **(c) Dryopteris**: Dryopteris is another type of fern. Similar to Pteris, the sporophyte is independent and does not show partial dependence on the gametophyte. Thus, this option is not correct.

- **(d) Selaginella**: Selaginella is a type of lycopod. The sporophyte in Selaginella is also independent and does not exhibit partial dependence on the gametophyte. Therefore, this option is not correct.

### Step 3: Conclusion
After analyzing all the options, we find that the only plant with a partially independent sporophyte is **(b) Funaria**.

### Final Answer:
**(b) Funaria**
