The Correct Option is A

Solution and Explanation

In botany, a composite fruit is a type of fruit that develops from a group of flowers that are clustered together in an inflorescence. Inflorescence is a flowering stalk that holds multiple flowers.

Here's how composite fruits form:

  1. A group of flowers on an inflorescence are pollinated.
  2. Instead of each flower developing into a single fruit, the ovaries of the flowers fuse along with other parts of the inflorescence.
  3. The result is a single fruit that contains multiple seeds from the individual flowers.

Other answer choices are not correct because:

  • Simple fruit: A simple fruit develops from a single flower with one carpel.
  • Aggregate fruit: An aggregate fruit develops from a single flower with multiple carpels.
  • Amphisarca fruit: I couldn't find a definition for amphisarca fruit in my search. It might be a misspelling of another term or a term not widely used in botany.

Thus, the right answer to this question is composite fruit.

Morphology of Flowering Plants

Morphology in flowering plants tells us that every plant has two systems such as a root system and a shoot system. The root system digs deep into the ground and structures a system of its own. On the other hand, the shoot system is the one that is above ground level and includes various plant parts. 

Root System

The descending part of the plant grows under the soil roots. During the germination process, the radicle from the seed grows earthward and branches out. The branches along with the primary root are called the root system. Roots lack chlorophyll and therefore they are not green in color. Roots are positively geotropic and hydrotropic, that is, they grow downwards ground and water, and negatively phototropic, which is growing away from light.

There are three types of root systems found in plants are as follows:

  1. TapRoot System
  2. Fibrous Root System
  3. Adventitious Root System

Shoot System

The stem is also an essential element of the plant. It is the ascending portion of the plant axis that bears branches, flowers, leaves, and fruits, as well as aiding in water and mineral conduction. It is the plant's aerial portion, brought about from an embryo's plumule or germinating seeds. Young stems are ordinarily green, but they finally turn woody and brown.
