Digestion in ctenophores is

Options

A. extracellular
B. intracellular
C. both 1 & 2
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Digestion in Ctenophores**: Ctenophores, also known as comb jellies, exhibit two types of digestion processes: extracellular digestion and intracellular digestion.

2. **Extracellular Digestion**: This process involves the secretion of digestive enzymes into the environment. Ctenophores release these enzymes to break down food particles outside their cells. The nutrients from the digested food are then absorbed into the ctenophores' body.

3. **Intracellular Digestion**: In addition to extracellular digestion, ctenophores also perform intracellular digestion. After engulfing food particles, the ctenophores absorb them into their cells, where the cytoplasm digests the food and absorbs the nutrients.

4. **Conclusion**: Ctenophores utilize both extracellular and intracellular digestion processes to obtain nutrients from their food.

5. **Final Answer**: Therefore, digestion in ctenophores involves both extracellular and intracellular digestion.
