Generally development is considered as the sum of

Options

A. linear growth and lateral growth
B. growth and seed germination
C. differentiation and growth
D. seed germination and reproduction

Answer

To answer the question "Generally development is considered as the sum of," we can break down the concepts involved in plant development. Here’s a step-by-step solution:

### Step 1: Understand the Concept of Development
- Development in plants refers to the series of changes that occur throughout the life cycle of the organism, from seed germination to senescence (aging).

### Step 2: Identify Key Processes in Development
- The main processes involved in plant development include:
- **Growth**: This refers to the increase in size and mass of the plant.
- **Differentiation**: This is the process by which cells become specialized to perform specific functions.

### Step 3: Analyze the Options Given
- The options provided are:
1. Linear growth and lateral growth
2. Growth and seed germination
3. Differentiation and growth
4. Seed germination and reproduction

### Step 4: Determine the Correct Answer
- Among the options, the most comprehensive and relevant to the definition of development is **option 3: differentiation and growth**. This is because development encompasses both the increase in size (growth) and the specialization of cells (differentiation).

### Conclusion
- Therefore, the correct answer is that development is generally considered as the sum of **growth and differentiation**.
