The persistent nucellus in the seeds of some plants is called EndospermPerispermScutellumPericarp

Remnants of nucellus are persistent during seed development in:a) peab) groundnutc) wheatd) black pepper

A triploid proteinaceous layer, which is the outer covering of endosperm is present in the seeds ofCastorBeanMaizePea

A biologist collected seeds from 10 different plants, keeping all seeds under optimal conditionsof storage. Within a week after collection the seeds were germinated under laboratory conditions.Each set of seeds was placed onto moist filter paper which was remoistened as necessary andsubjected to room temperature of 23˚C. Half the seeds of each group received 24 hours of light, theother half were kept in darkness. Within variable periods of time the seeds of certain plants kept inthe light germinated. The seeds of other plants kept in the dark germinated. Some sets of seedsgerminated under both light regimes. One set of seeds did not germinate under either lightcondition. What might be a LOGICAL hypothesis, consistent with the data, for the lack ofgermination of the one set of seeds?A. The seeds required 12 hours of light and 12 hours of darkness in order to germinate.B. All the seeds of that group were dead.C. The seeds required an elevated temperature in order to germinate.D. The seeds required vernalization in order to germinate.E. None of the above is logical.

The major parts of the seed are the hull, endosperm and germ.Group of answer choicesTrueFalse

After fertilization in angiosperms, part of the flower develops into a , which contains the seeds and helps protect and disperse them.
