The scutellum observed in a grain of water or maize is comarable to which part of the seed in other monocotyledons?

If the chromosome number in the root cell of Zea mays is 20 , then what would be the chromosome number in the cell of (i) radicle, (ii) hypocotyls , (iii) epiblast , (iv) aleurone layer and (v) scutellum, respectively ? {:(,(i),(ii),(iii),(iv),(v)),((1),20,30,20,30,20),((2),20,20,20,30,20),((3),20,30,30,30,20),((4),20,20,20,20,20):}

In maize seed, the outer covering of endosperm is proteinaceous and called as (1) Scutellum (2) Pericarp (3) Aleurone layer (4) Coleoptile

Assertion : Orchid is monocotyledonous non-endospermic seed while castor is dicotyledonous endospermic seed Reason : In monocotyledonous (wheat and maize) cotyledon is one while is dicotyledonous (gram and pea) there are two cotyledons.

Given below is a diagram of maize grain. Label the missing parts with the correct options (a) A -Endosperm, B - Coleoptile, C - Scutellum , D - Aleurone layer (b) A - Cotyledon , B - Coleoptile, C - Scutellum , D - Epithelium (c) A - Endosperm, B - Coleorhiza, C - Scutellum , D - Epithelium (d) A - Endosperm, B - Coleoptile, C - Scutellum , D- Radicle

Some characters are given below, which of the following is correct about seeds of maize? (A) Seed coat is membranous and generally fused with fruit wall. (B) The outer covering of endosperm separates embryo by aleurone layer. (C) The plumule and radicle are not covered with coleoptile and coleorhiza respectively. (D) Embryo consists of two large shield shaped cotyledous known as scutelum.

In the formation of endosperm of wheat, which of the following cell is involved? 1) Antipodal cell 2) Synergid cell 3) Central cell 4) Egg cell
