The production and storage of energy in mitochondria increases during:
1 seed germination
2 dormant seed
3 ripening seed
4 seed maturation
Explanation:
A The production and storage of energy in mitochondria increases during seed germination. The reserves food materials are rapidly oxidized and release energy for various biosynthetic activities going on in the germinating seed.

Secondary dormancy is due to the absence of
1 suitable plant
2 hormones
3 favourable conditions
4 unfavourable conditions
Explanation:
C Secondary dormancy is due to the absence of favourable condition. An important function of seed dormancy is delay germination which allows dispersal and prevents simultaneous germination of all seeds secondary dormancy occurs due to unfavourable conditions occur after the seed has been dispersed.

Which one of the following does not exhibit seed dormancy?
1 Rhizophora
2 Xanthium
3 Phaseolus
4 Cassia
Explanation:
A Rhizophora does not exhibit seed dormancy while being attached to the parent plant. As viviparous plant, Rhizphora creates a propagate that is in reality a living tree. Hence, option (a) is correct answer.

Removal of seed coat in dormant seeds, by mechamical method is called :
1 separation
2 vernalization
3 emasculation
4 scarification
Explanation:
D Removal of seed coat in dormant seeds by meachanical method is called scarification. It involves weakening, breaking, opening, scratching or altering the coat of seed, testa, by chemical or mechanical method to encourage germination.
