Answer (d) Die after flowering once is its life cycle

In gynandrous condition, stamens are partly or wholly united with the gynoecium, as in madder (Calotropis).

Cyathium is a special type of inflorescence. It is highly reduced and looks like a small flower. In this case an involucre of bracts fuses to form a deep cup-like structure. Nectaries are present at the rim of the cup. Many unisexual flowers are present in this cup. In the centre there is a single female flower. It is highly reduced and represented by a tricarpellary, syncarpous, gynoecium. This female flower is surrounded by 4-5 groups of male flowers. Male flower is also highly reduced and is represented by a single stamen. This inflorescence is found in some members of Euphorbiaceae like Euphorbia sp. and Poinsettia sp.

Answer (b) Clematis

Aggregate fruits are the group of fruitlets which develop from the multicarpellary, apocarpous ovary. The individual carpel or pistil develops into a ffuitlet but these fruitlets mature as clustered unit on a single receptacle. Such type of aggregate fruits, developed from the single flower
is known as etaerio. These fruits make an aggregation of fruitlets.

Runners have long and thin intemodes and branches creep over the surface of soil. Such branches develop adventitious roots at nodes on lower side. Scaly leaves are present on nodes, from the axil of which arise aerial branches. When long branches break up by any method they form new plants. In this way large number of new plants are formed, e.g., Doob grass, Oxalis, Hydrocotyle.

Cereals such as wheat, maize, rice, oat, barley etc. belong to Family Poaceae.

The formation of pericarp takes place from ovary wall. Ovary wall is changed into the pericarp after fertilisation.

In compound corymb, the branching occurs on main axis and the peduncle becomes shorter and the pedicels of lower flowers become longer than the upper flowers due to which all flowers come on the same level of height. E.g., Cauliflower, Pyrus malus.

When the sepals, petals and stamens are successively and separately inserted below the ovary in the flowers, the condition is known to be hypogyny and the ovary is said to be superior. Hypogynous ovary looks convex as the floral parts are present below the thalamus.

Answer (b) wild pea

Answer (c) Diageotropic

Answer (b) Mesopodium

The arrangement of leaf on a stem or branch is called phyllotaxy. phyllotaxy is found in tristichous or three-ranked phyllotaxy.
Hence, the angular divergence is of or phyllotaxy.
