Plant Morphology and Physiology

Rate of transpiration is directly propotional to water availablity. The lack of water supply can prompt other changes that reduce the rate of transpiration.

''Tip hooking'' disease is a deficiency disease in plants.

It is a micronutrient & an enzyme cofactor. It is also required for photosynthesis in plants.

It is a macronutrient & is an essential constituent of the proteins. Indian soil is mainly deficient in nitrogen.

It is a physiological disorder incited by calcium deficiency in apples.

An egg apparatus is consisted of group of three cells in the seven-celled embryo sac of an angiosperm consisting of the egg cell and two associated cells called synergids. It is located at the end of the embryo sac.

Apomixis causes certain changes in the female reproductive system such that female gametes develop without meiosis, leading to the development of embryos without fertilisation.

It is defined as the process of development of a gametophyte directly from a sporophyte without the occurrence of meiosis or spore formation.

Wilhelm Turesson was an ecological genetics. He is famed for coining the terms 'ecotype' and 'agamospecies'.

It signifies a peculiar type of inflorescence having a number of simple dichasial cymes arranged in a racemose manner on an elongated peduncle. Hence, it is also called mixed type, e.g. ocimum.

Hypanthodium signifies to a peculiar type of inflorescence. The penducle becomes fleshy, flattened and forms a hollow cup with a small opening at the top. The male and female flowers are borne on the inner wall of the cup or receptacles with male flowers are the base of receptacle. The flowers are usually sessile, e.g. rubber.

These are the type of climbers which climbs using their aerial adventitious roots developed at the nodes, e.g. betel, black pepper, etc.

These plants are characterised by the presence of long, thin & slender stems with branches. They climb by twining bodily around trees and shrubs, e.g. ipomoea.

In multiparous, more than two branches develop at a time. It is also known as polychasial, e.g. Euphorbia.

It is defined as a structure where the petiole of a leaf gets modified into a green flat structure for serving the purpose of photosynthesis, e.g. Acacia melanoxylon.

Here the stipules of a leaf fuses by their outer margins in a position opposite to the leaf attachment, e.g. Ficus elastica.

It is a simple, dry, indehiscent fruit, e.g. acer.

These stipules get associated with the petioles of the leaves with the help of their inner margins, e.g. rose.

It is a simple, dry, dehiscent fruit originating from a syncarpous ovary.

It is a simple fleshy fruit. 

It is a simple, dry, dehiscent fruit developing from the bicarpellary, monolocular ovary having 2 parietal placentae. 

It is defined as a flattened stem consisting of several internodes functioning as a leaf. In Opuntia, the stem is modified into a green flattened structure called phylloclade.
