Hint: Every part of the plant is important to be studied, as it will give us an understanding of its function, economic value and to treat if they get infected. Flowers in plants are not only for its aesthetics. They carry the reproductive organs in case of flowering plants.
Complete answer:
The stem is a plant axis that contains shoots, leaves, buds and roots. It transports water, minerals and nutrients to other parts of the plant.
There are 3 types of stem modification: 1. Underground modification, 2. Sub-aerial modification 3. Aerial modification.
> Underground modification: Their types are: Rhizome- It is non-green and fleshy type of underground stem with nodes as well as internodes and the nodes have dry, scale leaves with axillary buds. Rhizomes grown obliquely are known as root-stock and those which are grown horizontally are known as straggling. Example: Dryopteris, Nelumbo nucifera, Alocasia, etc.
Corm- They grow in vertical direction and have a flat base and are somewhat spherical in shape. It also contains circular nodes and internodes. Example: Colocasia, Amorphophallus, Crocus sativus, etc.
Tuber- They are used to provide energy and nutrients. It is a swollen tip of an underground stem. Example: Potatoes, Helianthus tuberosus, Solanum Tuberosum, etc.
> Sub-aerial modification: Their types are: Sucker- They arise from the basal part of the main stem and grow horizontally under the soil and obliquely on the ground. Example: Apple tree, Cherry Tree, Banana tree, etc.
Stolon: It also arises from the base of the main stem . It grows aerially and then bends towards the ground.
> Aerial modification: Their types are: Stem tendrils: The stem are modified to green thread like leafless structure i.e. tendrils which are used for climbing.
Thorns: They are pointed, hard and sometimes also possess leaves and flowers and they are used for defense.
Hence, option (a), (b) and (d) are the correct pair so the incorrect pair is option (c) and thus, the correct answer is option (c).
Note: Anthology not only means study of flowers. It also means a collection of literary works done by a compiler. The collected materials can be poems, stories, songs, or plays written by different authors. However, it can be a collection of works done by the same author as well.
