Growth in living being in mainly by

Options

A. Accretion
B. Aggregation
C. Intussusception
D. Accumulation

Answer

**Step-by-Step Solution:**

1. **Understanding Growth in Living Beings:**
- Growth in living organisms can occur through various processes. To determine the correct process, we need to analyze the given options: accretion, aggregation, interception, and accumulation.

2. **Evaluating the Options:**
- **Accretion:** This refers to growth by the gradual accumulation of additional layers or matter. While this is a form of growth, it is not the primary method by which living beings grow.
- **Aggregation:** This involves the formation of a number of things into a cluster. While aggregation can occur in biological systems, it does not directly describe the growth process of living organisms.
- **Interception:** This process refers to the increase in surface area, particularly the cell wall of cells, through the deposition of materials like cellulose. This is a key process in the growth of plant cells.
- **Accumulation:** This describes a mass or quantity of something that has gradually gathered over time. While accumulation can occur, it is not the main method of growth in living beings.

3. **Identifying the Correct Process:**
- After analyzing all the options, it becomes clear that the process of **interception** is the most relevant to growth in living beings, especially in the context of plant cells where the cell wall expands due to cellulose deposition.

4. **Conclusion:**
- Therefore, the correct answer to the question "Growth in living beings is mainly by" is **interception**.
