Question

Which is the common ingredient used to form the base of solid media in plant tissue culture?

• A. Agar
• B. Agarose
• C. Sucrose
• D. Inorganic salts

Hint:

Remember that agar is the key gelling agent used to create solid media in plant tissue culture.

Answer 1

The Correct Option is A

Step 1: Concept
Plant Tissue Culture Media Components

Step 2: Meaning
Understanding the key components required for plant tissue culture, particularly the role of agar as a gelling agent.

Step 3: Analysis
Agar is commonly used in plant tissue culture to solidify media. While sucrose provides nutrients and energy, agarose and inorganic salts have different functions but are not primary bases for solid media.

Step 4: Conclusion
Agar forms an essential base for solidifying the media in plant tissue culture, providing a stable matrix for plant cells to grow on. Final Answer: (A)
