Correct Answer
A. Broccoli
Explanation
Broccoli is an example of a newly developed plant variety because it is a relatively recent addition to the vegetable market. It was developed through selective breeding techniques to create a distinct variety with specific traits, such as its unique florets and high nutritional value. Cauliflower and carrot, on the other hand, have been cultivated for centuries and are not considered newly developed plant varieties.

What is the name of the green pigment present in plants, necessary for photosynthesis?
Correct Answer
B. ChloropHyll
Explanation
Chlorophyll is the correct answer because it is the green pigment found in plants that is essential for photosynthesis. It absorbs light energy from the sun and converts it into chemical energy that is used to fuel the photosynthetic process. Without chlorophyll, plants would not be able to carry out photosynthesis and produce food. Cellulose is a structural component of plant cell walls, while adenosine triphosphate (ATP) is a molecule that stores and releases energy in cells.

What is the world's fastest-growing plant?
Correct Answer
C. Bamboo
Explanation
Bamboo is the correct answer because it is known as the world's fastest-growing plant. Some species of bamboo can grow up to 91 cm (36 inches) in just 24 hours.
