The Correct Option is A

Solution and Explanation

In cabbage plant, the stem is so short that the great mass of thick overlapping leaves tend to form a head. The older leaves surround the younger smaller, more tender leaves and the cabbage resembles a huge bud. In cauliflower a short erect stem is produced with an undeveloped infloresence. The whole inflorescence forms a large head of abortive flowers on thick hypertrophied branches. The onion bulb consists of edible fleshy leaf bases. Agave provides "Sisal Hemp".

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.
