Consider the given statements regarding patterns of life cycle in living organisms:

I. In haplontic life cycles, zygotes are the only diploid cells; mitosis occurs only in the diploid phase.
II. In diplontic life cycles, gametes are usually the only haploid cells, and mitosis usually occurs only in the haploid phase.
III. In haplo-diplontic life cycle, alternation of generations is marked and mitosis occurs in both haploid and diploid phases.

All the following regarding resemblances of Gnetum with angiosperms are true except:
1. Presence of true vessels in secondary wood
2. Only one integument surrounding the ovule
3. Perianth in both male and female flowers
4. Absence of archegonia

Seeds make their appearance for the first time in gymnosperms. All the following factors are responsible for its development except:
1. Heterospory and differentiation of sporophylls and sporangia
2. Retention of megaspore within the megasporangium
3. Female gametophyte devoid of any integument
4. Development of young sporophyte within tissue of the megasporangium

In Cycas:

I. Micro sporophylls bear two elongated sac like structures at the base on the ventral side called pollen sacs.
II. Pollen grains are winged.
III. Megasporophylls are compact when young but spread apart when mature.
IV. Each megasporophyll has (a) bract scale and (b) ovuliferous scale which bears 2 ovules on the ventral side.

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.

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.
