Which of the following is a partial root parasite?

Options

A. Sandal wood
B. Mistletoe
C. Orobanche
D. Ganoderma

Answer

To determine which of the following is a partial root parasite, we can analyze each of the options provided:

1. **Sandalwood (Option A)**: Sandalwood is known to be a partial root parasite. It has the ability to synthesize its own food through photosynthesis, but it relies on the roots of host plants to obtain water and inorganic nutrients. This characteristic defines it as a partial root parasite.

2. **Mistletoe (Option B)**: Mistletoe is primarily a partial stem parasite. It attaches to the stems of host plants and derives nutrients from them, but it does not primarily affect the roots.

3. **Orobanche (Option C)**: Also known as broomrape, Orobanche is a complete root parasite. It does not perform photosynthesis and relies entirely on the host plant for all its nutritional needs, including water and nutrients.

4. **Ganoderma (Option D)**: Ganoderma is a type of fungus and is not classified as a root parasite. It typically grows on decaying wood or as a saprophyte, deriving nutrients from dead organic matter.

Based on this analysis, the correct answer is:

**The right answer is Option A: Sandalwood, which is a partial root parasite.**
