The scutellum observed in a grain of wheat or maize is comparable to which part of the seed in other monocotyledons?
1 Cotyledon
2 Endosperm
3 Aleurone layer
4 Plumule
Explanation:
A The scutellum is referred to as equivalent to thin cotyledon in monocots (especially members of the grass family). It is very thin with high surface area and serves to absorb nutrients from the endosperm during germination. Endosperm- endosperm is a tissue produced inside the seeds of the flowering plants following double fertilization. It is triploid in most species.

The viability of seeds is tested by
1 Safranine
2 2, 6 dichlorophenol indophenols
3 2,3,5 triphenyl tetrazolium chloride
4 DMSO
Explanation:
C Viability of seeds can be known by two methods: (i) Ability to germinate. (ii) Testing their ability to respire. All viable seeds respire. This can be tested by immersing a section of seed containing the embryo in \(0.1 \%\) solution of triphenyl tetrazolium chloride. - The viable embryo will turn pink due to conversion of colourless triphenyl tetrazolium chloride into insoluble coloured dye called triphenyl formazan due to reduction.

Some seeds produce various structures like wings, pappus calyx, hooks etc, which help in their
1 protection
2 dispersal
3 attraction
4 germination
Explanation:
B Seed dispersal is the mechanism that helps in the transport of seeds to other place pappus calyx, wings, hooks etc. helps in the dispersal of seed. Pappus is the modified calyx.
