Parasite plants obtain nourishment through

Options

A. Roots
B. Haustoria
C. Thorns
D. Pores

Answer

**Step-by-Step Solution:**

1. **Understanding Parasite Plants**: Parasite plants are those that derive some or all of their nutritional requirements from another living plant. They are often classified into two main categories: holoparasites and hemiparasites.

2. **Holoparasites**: These are completely dependent on their host for all their nutritional needs. They do not perform photosynthesis and obtain water, nutrients, and carbohydrates directly from the host plant. Examples include plants like dodder (Cuscuta) and broomrape (Orobanche).

3. **Hemiparasites**: These plants can perform photosynthesis but still rely on their host for water and nutrients. They have chlorophyll and can produce some of their own food, but they still extract water and minerals from their host. An example of a hemiparasite is mistletoe.

4. **Mechanism of Nutrient Uptake**: Parasite plants have specialized structures called haustoria that penetrate the host plant's tissues. Through these structures, they can absorb water and nutrients directly from the host.

5. **Conclusion**: Therefore, parasite plants obtain nourishment through their haustoria by extracting water and nutrients from their host plants.

**Final Answer**: Parasite plants obtain nourishment through haustoria by extracting water and nutrients from their host plants.
