Question

Phanerogamae are
A. Seed plants in which sex organs are evident
B. Non-seed plants
C. Non-seed plants in which sex organs are hidden
D. None of the above

Answer 1

Hint: Plants are eukaryotic, multicellular organisms which contain chlorophyll for carrying out photosynthesis. The plant cells bear a rigid cell wall. Plants kingdom can be divided into different subgroups depending on their common and exclusive features.

Complete Solution:
Plants are the food producing organisms which produce their own food through the process of photosynthesis. Plants are a vast community and consist of a variety of different features. The Plant kingdom can be divided into five subgroups which are Thallophyta, Bryophyta, Pteridophyta, Gymnosperms and Angiosperms.

Thallophytes lack a well differentiated body and are plants with primitive characteristics. The Bryophytes do not bear a vascular body and are also known as the amphibians of the plant kingdom. Pteridophytes are plants that have a well-developed body with roots, stem and leaves. Gymnosperms and Angiosperms are the seed bearing members of the plant family.

As proposed by botanist, A.W.Eicher, on the basis of flowering and seed bearing features, the plants are grouped into two groups- the Cryptograms and the Phanerogams. The classification system proposed by Eicher employed two important characteristics such as presence of flowers and production of seeds to classify the different types of plants.

According to the proposed system of classification, the Cryptograms are the plants which had no seeds or flowers. They are the types of plants which had concealed reproductive units or organs. This means that the reproductive parts of the Cryptograms are not exposed and are hidden. They are the seedless plants. The group Cryptogram includes the Thallophytes, the Bryophytes and the Pteridophytes.

The Phanerogams are the groups of plants that bear visible and prominent reproductive organs. They are the seed producing plant group of the plant kingdom. In this group, the plants show distinct and evident sexual organs or reproductive organs. They are also known as the spermatophytes. The Phanerogams are further classified into the gymnosperms and the angiosperms.

The gymnosperms are the seed bearing plants but their seeds are not enclosed in seed covering and are exposed while in the angiosperms, the seeds are covered inside a coating or coverings. The angiosperms are the flowering plants and they produce fruits and are a diverse group of plants.
Therefore, the option A is the correct and appropriate option.

Note: In the phanerogams plant group, they show the feature of visible reproductive organs. The sex organs or the organs of reproduction are not hidden and are very much prominent. They are the most recent types of plants and have a well vascular system. They are also known as the spermatophytes.
