The lateral roots originate froma)Endodermis cellsb)Cortical cells below root hairc)Pericycle cellsd)EpiblemaCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Lateral roots start to develop in the pericycle cells, which is the outermost cell layer in the vascular cylinder. Remember that the xylem and phloem make up the vascular cylinder and that it is found in the center of the root.

Answer

C

Answer

Lateral roots originate from pericycle cells.

Explanation:
The pericycle is a tissue located just inside the endodermis, which is the innermost layer of the cortex in the root. The pericycle is responsible for the formation of lateral roots in plants.

1. Pericycle as the origin of lateral roots:
- The pericycle is a specialized layer of cells that surrounds the central vascular tissue in the root.
- It is located between the endodermis and the vascular tissue.
- The pericycle cells have the ability to divide and differentiate, giving rise to new structures such as lateral roots.
- When a plant needs to develop new roots for increased absorption of water and nutrients, it initiates lateral root formation from the pericycle cells.

2. Process of lateral root formation:
- Lateral root initiation begins with the pericycle cells undergoing cell division.
- The pericycle cells adjacent to the xylem poles are usually the ones that undergo division and give rise to new lateral roots.
- The pericycle cells adjacent to the phloem poles can also contribute to lateral root formation.
- After cell division, a small bump or primordium is formed, which grows out from the main root.
- The primordium elongates and develops into a lateral root that eventually emerges from the main root.

3. Importance of lateral roots:
- Lateral roots play a crucial role in plant growth and development.
- They increase the surface area of the root system, allowing for better absorption of water and nutrients from the soil.
- Lateral roots also provide anchorage and support to the main root and the plant as a whole.
- They help in exploring new areas of the soil for resources and contribute to the overall health and vigor of the plant.

In conclusion, lateral roots originate from the pericycle cells, which are located just inside the endodermis. The pericycle cells have the ability to divide and give rise to new lateral roots, which are important for the plant's growth, nutrient absorption, and overall health.
