2003 AIPMT Plant KingdomBryophytes: Moss Sporophyte Medium Question 97 of 105 in Plant Kingdom

Chlorenchyma is found in : -

A Cytoplasm of Chlorella
B Mycelium of a green mould such as Aspergillus
C Spore capsule of a moss
D Pollen tube of Pinus

The answer is C.

Solution

Chlorenchyma is a tissue: parenchyma cells containing chloroplasts, which carry out photosynthesis.
Chlorella is a unicellular alga, so it cannot have a tissue; its cytoplasm just contains a chloroplast.
Aspergillus is a fungus; its mycelium has no chloroplasts (the green colour is due to spores). The pollen tube of Pinus also lacks chloroplasts.
The capsule of the moss sporophyte has photosynthetic tissue (chlorenchyma) in its wall, below the epidermis, around the air spaces. This allows the sporophyte to make part of its own food.
So chlorenchyma is found in the spore capsule of a moss.
