What type of modification of root is found in the: (a) Banyan tree (b) Turnip (c) Mangrove trees Answer.Roots of some plants change their shape and structure and become modified to perform certain functions other than absorption and conduction of water and minerals. It is called modification of roots. Roots are modified for support, storage of food and respiration, etc. (a) Root modification in banyan tree : The banyan tree (Ficus benghalensis) has massive pillar-like adventitious roots arising from the aerial part of the stem. These roots grow towards the ground and provide support to the tree. Such roots are called prop roots. (b) Root modification in turnip : The modification of root found in turnip is napiform for food storage. The upper portion of these fleshy roots is inflated or swollen which tapers towards the lower end. (c) Root modification in mangrove trees : The roots of mangrove plants grow vertically upwards from the soil for the abso...

Based on the position of the calyx, corolla, and androecium (with respect to the ovary on the thalamus), the flowers are described as hypognous, perigynous, and epigynous. In hypogynous flowers, the ovary occupies the highest position on the thalamus while other floral parts are situated below it. In such flowers, the ovary is superior e.g., China rose, mustard etc. In perigynous flowers, the ovary is situated at the centre and other floral parts are arranged on the rim of the thalamus. The ovary here is said to be half inferior e.g., plum, rose, peach In epigynous flowers, the thalamus grows around the ovary fusing with its wall. The other floral parts are present above the ovary. Hence, the ovary is said to be inferior e.g., flowers of guava and cucumber.

Based on the position of calyx, corolla and androecium in respect of the ovary, on thalamus, the flowers are described as (a) hypogynous: In the hypogynous flower, the gynoecium occupies the highest position while the other parts are situated below it. The ovary in such flowers is said to be superior. Example: Mustard, China rose, brinjal. (b) Perigynous: If gynoecium is situated in the centre and other parts of the flower are located on the rim of the thalamus almost at the same level, it is calledperigynous. The ovary here is said to be half inferior. Example: Plum, Rose, Peach. (c) Epigynous: In epigynous flowers the margin of thalamus grows upward enclosing the ovary completely and getting fused with it, the other parts of flower arise above the ovary. Hence, the ovary is said to be inferior. Example: Guava, Cucumber, Sunflower.

In a typical flower, the floral members like calyx, corolla, androecium and gynOecium are arranged over the thalamus! Based on the position of calyx, corolla and androecium in respect to ovary on thalamus, the flowers are described as hypogynous, perigynous and epigynous ones. In the hypogynous flower the gynoecium occupies the highest position while the other parts are situated below it. The ovary in such flowers is said to be superior, e.g., mustard, china rose and brinjal. If gynoecium is situated in the centre and other parts of the flower are located on the rim of the thalamus almost at the same level, it is called perigynous. The ovary here is said to be half inferior or sub superior, e.g., plum, rose, peach. In epigynous flowers, the margin of thalamus grows upward enclosing the ovary completely and gets fused with it; the other parts of flower arise above the ovary. Hence, the ovary is said to be inferior as in flowers of guava and cucumber, and the ray florets of sunflower.

These are as follows: 1. Hypogynous – Ovary occupies the highest position while the other parts are situated below the ovary. The ovary in such case is called superior. Eg. Mustard, brinjal and China rose. Flowers with this arrangement are called hypogynous flowers. 2. Perigynous -In this arrangement, the gynoecium is situated at the centre and other parts are on the rim at the same height. Such ovary is called half-inferior and flowers are called perigynous flowers. 3. Epigynous-In this arrangement, the ovaryis situated below all the other parts. The ovary, in this case, is said to be inferior while the flower is called epigynous flower. ???????

Solution: The arrangement of floral members in relation to their insertion on thalamus are of three types: The ovary is said to be superior in hypogynous flowers because the gynoecium is at the top of the bloom and the other parts are below it. Example – Brinjal Perigynous flowers are those in which the gynoecium remains in the centre and the other components of the bloom are virtually at the same level as the thalamus rim. It is said that the ovary is half inferior. Example – Rose The epigynous flowers are those in which the thalamus edge grows upwards, enclosing the ovary. The ovary is said to be inferior because it is united with the thalamus and other elements of the flower rise above it. Example – Flowers of guava

Based on the position of the calyx, corolla, and androecium with respect to the ovary on the thalamus, the flowers can be grouped into three categories that are hypogynous, perigynous, and epigynous. Hypogynous flowers – In this the ovary occupies the highest position on the thalamus while other floral parts are situated below it. In such flowers, the ovary is superior. e.g., China rose, mustard etc. Perigynous flowers: The ovary is situated at the centre and other floral parts are arranged on the rim of the thalamus. The ovary here is said to be half inferior. e.g., plum, rose, peach. Epigynous flowers: The thalamus grows around the ovary fusing with its wall. The other floral parts are present above the ovary. Hence, the ovary is said to be inferior e.g., flowers of guava and cucumber.
