Type of nutrition and digestion in sponges are respectively

Options

A. holozoic - intercellular
B. holozoic- intracellular
C. holophytic -intracellular
D. holophytic - intercellular

Answer

To answer the question regarding the type of nutrition and digestion in sponges, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Identify the Type of Nutrition in Sponges**:
- Sponges exhibit a type of nutrition known as **holozoic nutrition**. This means they consume solid or liquid food particles.

2. **Understand Holozoic Nutrition**:
- Holozoic nutrition is also referred to as **heterotrophic nutrition**. In this process, organisms ingest food and then process it internally.

3. **Identify the Type of Digestion in Sponges**:
- The digestion in sponges occurs **intracellularly**. This means that the digestion takes place within the cells of the sponge.

4. **Explain Intracellular Digestion**:
- In sponges, there is no specialized digestive system. Instead, food particles are ingested and transported directly to **food vacuoles** within the cells, where they are broken down into simpler substances.

5. **Combine the Findings**:
- Therefore, the type of nutrition and digestion in sponges can be summarized as **holozoic** for nutrition and **intracellular** for digestion.

### Final Answer:
The type of nutrition and digestion in sponges are respectively **holozoic** and **intracellular**.
