Final answer:

Plants produce carbohydrates through photosynthesis, fungi like Aspergillus exhibit harmful and beneficial traits, sunflower seeds store starch, colored leaves can still carry out photosynthesis, and specific statements on photosynthesis processes are accurate.


Explanation:

Carbohydrates in plants are produced through photosynthesis using carbon dioxide and sunlight, leading to the synthesis of sugars like glucose. These carbohydrates serve as an essential energy source for plants and other organisms.

An example of fungi showcasing both harmful and useful traits is Aspergillus. It can be harmful by causing diseases like aspergillosis, but it is useful in producing citric acid for industrial purposes.

The stored food form in sunflower seeds is starch, which serves as an energy reserve for the developing plant.

Plants with deep red, violet, or brown colored leaves can still perform photosynthesis, as color variations in leaves do not necessarily disrupt the process of converting light energy into chemical energy.

The correct statement is iii) Photosynthesis requires carbon dioxide for the process, and iv) Oxygen is liberated during photosynthesis as a by-product.
