Mature embryos are mostly

Options

A. Autotrophic
B. Heterotrophic
C. Parasitic
D. Symbiotic

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the nature of mature embryos. We need to identify the correct term that describes them from the given options.

2. **Analyzing the Options**:
- **Option A: Ototropes** - This term seems to be a misspelling or confusion with "autotrophs," which refers to organisms that can produce their own food through photosynthesis.
- **Option B: Atotropes** - This term does not correspond to any known biological classification relevant to embryos.
- **Option C: Parasites** - Parasites depend on other living organisms for food, which does not describe mature embryos.
- **Option D: Symbiotic** - Symbiotic organisms engage in a relationship where both parties benefit, but this does not specifically describe mature embryos.

3. **Identifying the Correct Answer**: Based on the analysis, mature embryos are primarily **autotrophs** (assuming "ototropes" is intended to mean "autotrophs"). This means they can produce their own food, typically through photosynthesis.

4. **Conclusion**: The correct answer to the question "Mature embryos are mostly" is **Option A: Ototropes (interpreted as Autotrophs)**.
