Non-photosynthetic parts of the plant that require a supply of sucrose and amino acids include roots, stems, and developing fruits and seeds. These parts of the plant do not carry out photosynthesis, which is the process of converting light energy into chemical energy in the form of glucose. Instead, they rely on the transportation of sucrose and amino acids from photosynthetic tissues such as leaves, where photosynthesis occurs.
Sucrose serves as a primary form of energy transport in the plant and provides the necessary carbohydrates for growth and metabolism. Amino acids, on the other hand, are crucial for protein synthesis and various metabolic functions. The roots, which anchor the plant and absorb water and nutrients, are primarily reliant on these substances to support their growth and sustain their functional activities.
In summary, while the leaves fulfill the role of photosynthesis, the non-photosynthetic parts of the plant depend heavily on the products transported from these green parts to ensure overall growth and development.
