The process that causes the leaves of a plant to grow larger is B) growth.
Here's an explanation to help you understand better:
1. Plant Growth: Plants undergo growth processes throughout their life cycle, which includes the growth of various plant parts like leaves, stems, and roots.
2. Leaf Growth: In the case of leaves, growth occurs through cell division and cell expansion. Cell division allows for the formation of new cells, while cell expansion makes these cells increase in size.
3. Factors Affecting Leaf Growth: Factors such as sunlight, water, nutrients, and environmental conditions play a crucial role in promoting leaf growth. Adequate sunlight is essential for photosynthesis, a process where plants convert light energy into chemical energy, allowing them to produce food and grow.
4. Conclusion: Therefore, the process of growth in plants, including leaf growth, is essential for the development and enlargement of plant structures, enabling them to carry out vital functions like photosynthesis and overall plant growth.
