Which of the following is not true for the green alga Spirogyra?
1. Unbranched, filamentous and commonly found in stagnant fresh water bodies.
2. The filament is composed of large number of long, cylindrical cells placed one above the other in a single row.
3. The cells are characterised by long spiral ribbon-shaped chloroplasts with several pyrenoids.
4. There are multiple small vacuoles in each cell.

Identify the incorrect statement regarding Marchantia?
1. Thallus is dorsiventrally flat.
2. Thallus is dichotomously lobed, with an apical notch in each lobe.
3. There is a dark median furrow called mid-rib on the dorsal side that extends into each lobe.
4. Small cup-like structures called gemma cups are borne on the ventral surface of the thallus.

Identify the correct statement regarding Marchantia:
