Introduction:
Zaminkand is a type of stem that can be differentiated from roots based on several characteristics. In this response, we will discuss these characteristics in detail.

Characteristics of Zaminkand:
Zaminkand possesses the following characteristics that differentiate it from roots:

1. Grows parallel to the ground:
Unlike roots that grow vertically or obliquely into the soil, Zaminkand grows parallel to the ground. It spreads horizontally and can cover a significant area, making it suitable for ground cover or vegetation control.

2. Stores food:
One of the distinguishing features of Zaminkand is its ability to store food. The stem of this plant accumulates and stores nutrients, such as starch, in specialized tissues. These stored reserves are utilized during periods of dormancy or when the plant requires energy for growth or reproduction.

3. Lacks chlorophyll:
Unlike green stems or leaves, Zaminkand lacks chlorophyll, the pigment responsible for photosynthesis. This absence of chlorophyll gives it a different coloration compared to green plant parts. The stem may appear brown or pale, depending on the species.

4. Has nodes and internodes:
Zaminkand possesses nodes and internodes along its length. Nodes are points on the stem where leaves, buds, or branches arise, while internodes are the segments between nodes. These structures play a crucial role in the growth and development of the plant, facilitating branching, leaf emergence, and reproductive structures.

Conclusion:
In conclusion, Zaminkand can be differentiated from roots based on its growth habit, lack of chlorophyll, food storage capacity, and presence of nodes and internodes. Understanding these characteristics helps in identifying and classifying plants correctly, contributing to our knowledge of plant diversity and functioning.

Zaminkand is a corm. So the answer will be D
