Its phyllotaxy is:Alstonia has more than two leaves at a node forming a ring. This phyllotaxy is:A flower is a modified shoot whose apical meristem becomes a:In a cymose inflorescence the main axis:Calyx and corolla are called ___ organs of the flower.In lily the calyx and corolla look alike and are together called the:A canna flower cannot be cut into two similar halves by any plane. It is:A flower with a reduced leaf at the base of its pedicel is:Sepals are usually green and protect the flower in the:In Calotropis the petals just touch at the margins without overlapping. This aestivation is:A stamen is made of a filament and an:After fertilisation the ovary matures into a fruit and the ovules become:In a maize seed the radicle is enclosed in a sheath called the:What shape of covering protects the tender apex of a growing root?From which part of the embryo of a germinating seed does the stem develop?Which are the three main parts of a typical leaf?What is the swollen leaf base of some leguminous plants called?What is the prominent middle vein of a leaf lamina called?Besides carrying materials, what do veins give a leaf blade?What is the arrangement of veins and veinlets in a lamina called?Which venation do most monocotyledons show?When veinlets form a network in the lamina, the venation is termed what?A leaf whose lamina incisions reach the midrib, making leaflets, is called what?In a compound leaf, where is a bud absent?In a pinnately compound leaf, the leaflets sit on which axis?What is the pattern of arrangement of leaves on a stem called?Which plant shows alternate phyllotaxy with one leaf at each node?Which pair of plants shows opposite phyllotaxy?Alstonia shows which type of phyllotaxy?A flower is best described as a modified what?When a shoot tip transforms into a flower, how is the flower borne?A cymose inflorescence has flowers borne in which order?What is the reproductive unit of angiosperms meant for sexual reproduction?Which two whorls of a flower are accessory organs?In lily, calyx and corolla are not distinct.
