Phycomycetes (fungal class from previous chapter) and Phaeophyceae (algal class) are easily confused. Identify the CORRECT statement about Phaeophyceae body parts.
ARoot → Stem → Leaves
BHoldfast (attaches to substrate) → Stipe (stalk) → Frond (leaf-like photosynthetic organ)
CAntheridium → Archegonium → Embryo
DMycelium → hyphae → spores
Answer & Solution
Correct answer: B. Holdfast (attaches to substrate) → Stipe (stalk) → Frond (leaf-like photosynthetic organ)
Phaeophyceae plant body has holdfast + stipe + frond. (Some species like kelps can reach 100 metres.) Mycelium belongs to fungi; true root/stem/leaves are pteridophytes+; antheridium/archegonium are sex organs in bryophytes/pteridophytes.
