B. cytological and embryological characters
C. phusiological and reproductive characters
D. all of these.

Answer

To answer the question "Natural systems of classification take into consideration," we can break down the information provided in the video transcript into a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding Natural Classification**:
- Natural systems of classification are designed to group organisms based on their natural relationships and affinities.

2. **Morphological Characters**:
- This includes the physical form and structure of plants, such as leaf shape, flower structure, and overall plant architecture.

3. **Cytological Characters**:
- This refers to the cellular characteristics of plants, including the number and structure of chromosomes, cell types, and other cellular features.

4. **Biochemical and Cytochemical Characters**:
- Biochemical characters involve the chemical processes and substances within plants, such as photosynthesis and metabolic pathways. Cytochemistry focuses on the chemical composition and processes at the cellular level.

5. **Anatomical Characters**:
- This involves the internal structure of plants, including tissue arrangement and organ structure.

6. **Physiological Characters**:
- These are related to the functions and processes of plants, such as growth, reproduction, and response to environmental factors.

7. **Ontogeny (Embryological Characters)**:
- Ontogeny refers to the development of an organism from fertilization to maturity, including embryological development.

8. **Conclusion**:
- Natural systems of classification take into consideration all these characters: morphological, anatomical, cytological, biochemical, physiological, and embryological. Therefore, the correct answer is that natural systems of classification consider all of these aspects.

### Final Answer:
Natural systems of classification take into consideration morphological, anatomical, cytological, biochemical, physiological, and embryological characters. Thus, the correct option is "all of these."
