biology fruit and seed morphology of the fruit fruit plants: structure and function

  1. Pomology

  2. Fruitology

  3. Pornography

  4. Economic botany

Show answer
Correct Option: A
Explanation:

Horticulture is the branch of agriculture that deals with growing plants used by people for food and medicine, as well as gardens and other forms of ornamental plants. This includes everything from fruits and vegetables to ornamental plants to spices. Anyone who works in any kind of garden is contributing to horticulture. One branch of horticulture is pomology, which is the branch that deals with fruit. The cultivation of any fruit crop falls under this branch, regardless of whether it is a single apple tree in someone's garden, or an entire orchard. Pomology includes everything from bananas to blueberries to strawberries and beyond.  Pomology deals with fruit plants throughout their life cycle, not just the fruit the plants produce. Horticulturalists in this branch cultivate fruit plants from seed all the way through fruit production.

So the correct option is 'pomology'.

Show answer
Correct Option: A
Explanation:
