Can plants grow without leaves?

Photosynthesis: Leaves contain chlorophyll, which is necessary for the plant to perform photosynthesis. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose, which is the plant’s primary source of energy.
-
Gas exchange: Leaves have tiny pores called stomata that allow the plant to take in carbon dioxide and release oxygen during photosynthesis. They also help the plant to release excess water vapor through transpiration.
-
Nutrient and water transport: Leaves are connected to the plant’s vascular system, which transports water, nutrients, and other essential molecules throughout the plant.

No, plants generally cannot grow without leaves. Leaves are essential for the proper growth and development of plants for the following reasons:
Photosynthesis: Leaves are the primary site of photosynthesis in plants. The leaf blade contains chloroplasts, which house the chlorophyll necessary for the conversion of sunlight, carbon dioxide, and water into glucose – the primary energy source for the plant.
Gas exchange: Leaves facilitate the exchange of gases between the plant and the atmosphere. They have stomata (pores) that allow the plant to take in carbon dioxide and release oxygen during photosynthesis, as well as release water vapor during transpiration.
Nutrient and water transport: Leaves are connected to the plant’s vascular system, which transports essential nutrients and water from the roots to the rest of the plant body.
Structural support: Leaves contribute to the overall structural support and stability of the plant, especially when they are arranged in a way that maximizes light exposure for photosynthesis.
While some plants can survive for a short period without leaves, they will eventually die if the leaves do not regrow. The only exceptions are plants that store energy in their roots, stems, or other underground structures, which can sometimes survive temporary defoliation. But in general, plants cannot grow and thrive without the essential functions provided by their leaves.
