What disease is affecting the cassava plant, how does it impact photosynthesis, and how is it transmitted?

a) Step 1: Observe the image and read the accompanying text for signs and symptoms. The image shows cassava plant parts, and the text mentions "yellow, green and deformed" leaves. Step 2: Identify the plant structure exhibiting these symptoms. The symptoms described (yellowing, greening, deformation) are characteristic of the leaves. b) Step 1: Recall the primary function of the affected plant structure. Leaves are the main sites for photosynthesis in plants. Step 2: Determine how the observed symptoms would impact this function. The yellowing (chlorosis) and deformation of leaves directly impair their ability to capture sunlight and produce food. The process being affected is photosynthesis. c) Step 1: Identify the nature of the infection based on the symptoms (likely Cassava Mosaic Disease). Cassava Mosaic Disease (CMD) is a viral disease. Step 2: Recall common transmission methods for plant viral diseases, especially CMD. Viral infections in plants are commonly spread by vectors and through infected plant material. The infection is spread and transmitted among plants through: • Insect vectors, primarily whiteflies (Bemisia tabaci), which feed on infected plants and then transmit the virus to healthy plants. • Using infected planting material (e.g., stem cuttings) from diseased plants for propagation.
