Growth in plants is

Options

A. only determinate
B. only indeterminate
C. mostly determinate
D. both determinate and indeterminate.

Explanation

### Step-by-Step Solution:

1. **Understanding Growth in Plants**:
- Growth in plants can be classified into two main types: determinate and indeterminate growth.

2. **Defining Indeterminate Growth**:
- Indeterminate growth refers to the ability of a plant to grow throughout its life. This means that there is no fixed size or limit to how much a plant can grow.

3. **Role of Meristems**:
- The reason for indeterminate growth in plants is the presence of specialized regions called meristems. These are areas of actively dividing cells that contribute to the growth of the plant.

4. **Types of Meristems**:
- There are two primary types of meristems:
- **Root Apical Meristem**: Located at the tip of the roots, responsible for root growth.
- **Shoot Apical Meristem**: Located at the tip of the shoots, responsible for stem and leaf growth.

5. **Continuous Growth**:
- Due to the activity of meristems, plants can continuously produce new organs such as leaves, flowers, fruits, and roots, which contributes to their ongoing growth.

6. **Conclusion**:
- Based on the understanding of plant growth, we can conclude that the correct answer to the question is that growth in plants is primarily indeterminate.

### Final Answer:
- The correct option is **indeterminate growth**.
