Question

Apophysis in moss capsule is:
A. Upper part
B. Middle part
C. Lower part
D. Fertile part

Answer 1

Hint:- Funaria's capsule (body containing spores) is divided into: theca (middle fertile part) and apophysis (sterile, firm basal portion of the capsule containing chloroplasts); operculum (cap shaped 2-3 layered thick lid on the rope).

Complete step-by-step solution:- The strong, very swollen basal, green photosynthetic portion of the capsule is the Apophysis. In essence, it is sterile. It also helps to control water and food resources. It eventually narrows down to seta; it is therefore often referred to as the capsule neck. The apophysis is internally covered by the epidermis. In the Funaria capsule, stomata are present only in apophysis.

Hence, Option C is the right answer.

Additional Information:
The Theca is the capsule 's primary fertile area. The capsule wall, spore sac and central columella are multilayered. The spore sac is typically present all around the columella, which is attached via external and internal trabeculae to the capsule wall on the outer side and to the columella on the inner side. The spore sac is dome-shaped in some mosses, which arches over the columella. The columella is usually present throughout, but in Archidium it is absent. Generally, the spores are tiny and present in large quantities. The spores are very large in few taxa such as Ephemarum and very few in number.

Note:-
Aquatic plants have specialised sections, such as roots , stems and leaves, whether floating, submerged, or emerging (starting in the water and rising out). There are also vascular structures in most plants (xylem and phloem), which hold nutrients all over the plant. While algae (like plants) contain chlorophyll, they do not have these specialised structures.
