Chlorenchyma is known to develop in the :
- Mycelium of a green mould such as Aspergillus
- Pollen tube of Pinus
- Cytoplasm of Chlorella
- Spore capsule of a moss
Answer
(4) Spore capsule of a moss
Solution
Chlorenchyma is parenchyma whose cells contain chloroplasts; it is a tissue, so it develops only in a multicellular, tissue-forming plant body.
∵ The mycelium of Aspergillus (a fungus) and the pollen tube of Pinus have no chloroplasts, and Chlorella is a unicellular alga (a single cell cannot form a tissue).
As per NCERT, the sporophyte of a moss (foot, seta and capsule) is photosynthetic; the wall of the capsule (apophysis region) has green chlorenchyma cells with stomata.
∴ Chlorenchyma develops in the spore capsule of a moss.
