Hormone primarily connected with cell division in

Options

A. IAA
B. NAA
C. Cyokinin/zeatin
D. Gibberllic acid

Answer

**Step-by-Step Text Solution:**

1. **Identify the Question**: The question asks for the hormone primarily connected with cell division in plants.

2. **Recall Relevant Hormones**: In plant biology, several hormones are involved in growth and development, including auxins, gibberellins, cytokinins, and abscisic acid.

3. **Focus on Cytokinins**: Among these hormones, cytokinins are specifically known for their role in promoting cell division (cytokinesis) in plant tissues.

4. **Understand the Name**: The term "cytokinin" can be broken down into two parts: "cyto-" refers to cells (or cytoplasm), and "-kinin" refers to division or synthesis. This etymology indicates that cytokinins are directly involved in cell division.

5. **Additional Functions**: Besides promoting cell division, cytokinins also stimulate tissue growth and influence various developmental processes in plants.

6. **Interaction with Auxins**: The activity of cytokinins is influenced by the concentration of auxins (another class of plant hormones). A high concentration of auxins and a low concentration of cytokinins can lead to root growth, while the opposite can promote shoot growth.

7. **Conclusion**: Based on the information gathered, the hormone primarily connected with cell division in plants is **cytokinin**.

8. **Final Answer**: The correct answer is **cytokinin**.
