On the basis of relative position of different floral parts on the thalamus, a flower can be hypogynous, Perigynous or epigynous. With respect to the given figures (A, B, C and D), select the correct option:
On the basis of relative position of different floral parts on the thalamus, a flower can be hypogynous, Perigynous or epigynous. With respect to the given figures (A, B, C and D),
On the basis of relative position of different floral parts on the thalamus, a flower can be hypogynous, Perigynous or epigynous. With respect to the given figures (A, B, C and D),

Detailed Solution: Question 1

There are three forms of thalamus in regard to the insertion of pistil and androperianth or other floral organs..
(i) Hpogyny - 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 ruperious. Such flowers are called hypogyous as in mustard,china rose and brinjal.
(ii) Epigyny - When the sepals, petals and stamens are successively and separately inserted above the ovary in the flower, the condition is descried as epigyny. The ovary in this situation is said to be inferior. Such flowers are termed epigynous, e.g., guave, cucumber.
(iii) perigymy - When the sepals, petals and stamens are inserted at the same plane as the ovary, the condition is known as perigyny. The ovary in such condition is half superior, sub-inferior or partially inderior ovary. Such flowers are called perigynous, e.g., rose, pea.
Topic in NCERT: THE FLOWER
Line in NCERT: "Based on the position of calyx, corolla and androecium in respect of the ovary on thalamus, the flowers are described as hypogynous, perigynous and epigynous."

If the gynoecium is present in the top most position of the thalamus, the flower is referred to as

Detailed Solution: Question 3

In hypogynous condition of flowers, the thalamus is convex or conical. Gynoecium occupies the topmost (superior) position at the thalamus and other parts of flower are borne successively below. Androperianth or other floral organs are inferior, e.g, Hibiscus rosa sinensis, Ranunculus, etc.

Topic in NCERT: Position of floral parts on thalamus

Line in NCERT: "In the hypogynous flower the gynoecium occupies the highest position while the other parts are situated below it."

Multiple Choice Questions (MCQs): The Flower - Question 4

Identify the different types of placentations shown in figure and select the correct option.

Detailed Solution: Question 4

The arrangement of ovules within the ovary is known as placentation. The placentation are of different type namely, marginal, axile, parietal, basal, central and free central. In marginal placemation the placenta forms a ridge along the ventral suture of the ovary and the ovules are borne on this ridge forming two rows, e.g. pea. When the placenta is axial and the ovules are attached to it in a multilocular ovary, the placentation is saidd to be axile, e.g., China rose, tomato and lemon In parietal placentation, the ovules develop on the inner wall of the ovary or on peripheral part. Ovary is one -chambered but it becomes two chambered due to the formation of false septum, e.g., mustard. When the ovules are borne on central axis and septa are absent, as in Primrose, the placentation is called free central In basal placentation, the placenta develops at the base of obary and a single ovule is attached to it, e.g., sunflower, marigold.

Topic in NCERT: Placentation

Line in NCERT: "Placentation: The arrangement of ovules within the ovary is known as placentation. The placentation are of different types namely, marginal, axile, parietal, basal, central and free central (Figure 5.12)."

Multiple Choice Questions (MCQs): The Flower - Question 5

Based on the position of floral parts on thalamus, the flowers, are described as hypogynous, perigynous and perigynous and epigynous. Which of the following floral forms (A-D) represent the flowers of Rose and Plum respectively?

Detailed Solution: Question 5

In perigynous condition of a filower, the gynoecium is situated in the centre and other floral parts are located on the rim of the thalamus almost at the same level. Ovary is said to be half-inferior, e g. Rosa (Flask-shaped thalamus) Prunus (Cup-shaped thalamus).
Topic in NCERT: Position of floral parts on thalamus
Line in NCERT: "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, e.g., plum, rose, peach."

Which of the following figures represent a typical placentation as seen in Hibiscus rosa sinensis (China rose)?

Detailed Solution: Question 6

Option (a) represents placentation as seen in China rose. It is axile type of placentation, which occurs in syncarpous pistils. Ovary is partitioned into 2 or more chambers. Placentae occur in the central region where the septa meet so that an axile column bearing ovules is formed. In China rose, ovary is pentalocular.

Topic in NCERT: placentation

Select the correct option for A, B and C in the given diagram of papilionaceous corolla.

Detailed Solution: Question 7

In papilionaceous corolla , five unequal petals are arranged like a butterfly. The posterior large bilobed petal is called standard or vexillum and it overlaps two smaller lateral petals called wings/alae. The latter in turn overlap the two anterior petals which are fused by the upper anterior margins to form a boat-shaped structure called keel or carina.
Topic in NCERT: Aestivation
Line in NCERT: "In pea and bean flowers, there are five petals, the largest (standard) overlaps the two lateral petals (wings) which in turn overlap the two smallest anterior petals (keel); this type of aestivation is known as vexillary or papilionaceous."
