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

Juicy hair-like structures observed in the lemon fruit develop from : -

  1. Exocarp

  2. Mesocarp

  3. Endocarp

  4. Mesocarp and endocarp

C Correct answer
Explanation

Endocarp in citrus is divided into segments, containing juicy hair like vesicles filled with the juice of the fruit.The epicarp or Flavedo is the outer most covering also called the rind, it contains oil glands.

The branch of horticulture that deals with the study of fruits and their cultivation is known as

  1. Pomology

  2. Fruitology

  3. Pornography

  4. Economic botany
Reveal answer Fill a bubble to check yourself
A Correct answer
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'.
