Question 1
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : Pea has vexillary type of aestivation.
Reason : In this type of aestivation, the posterior petal is the largest and covers almost the two lateral petals, and the latter in their turn, nearly overlap the two anterior or smallest petals.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D. A is false but R is true.

Solution

In vexillary type of aestivation, the posterior petal is the largest and covers almost the two lateral petals, and the latter in their turn, nearly overlap the two anterior or smallest petals. e.g, pea. This type of gestational is also called as descending imbricate aestivation.
Question 2
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : In perigynous flowers is ovary is called half-inferior.
Reason : Rose and plum plants bear perigynous flowers.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D
D. A is false but R is true.

Solution

In perigynous flowers , ovary is situated at the centre and other parts are on the rim of the thalamus hence, ovary is called half-inferior.
Question 3

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D
D. A is false but R is true.

In hypogynous flowers, ovary is said to be superior while in epigynous flowers, ovary is inferior.
Question 4
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : The symmetry of Mustard, Datura, and Chilli flowers is actinomorphic.
Reason : The actinomorphic flowers can be divided into two similar parts only in one vertical plane.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D
D. A is false but R is true.

Solution

The actinomorphic flowers can be divided into two similar of equal parts from more than one median plane.
Question 5
1 / -0

Directions : In the following question, the Assertions (A) and Reason (R) have been put forward. Read both the statements and choose the correct option from the following.
Assertion : Sunflower and Rose are bisexual flowers.
Reason : Flowers in which, the thalamus grows around the ovary fusing with its wall are called epigynous flowers.

A
A. Both A and R are true, and R is the correct explanation of A.

B
B. Both A and R are true, but R is not the correct explanation of A.

C
C. A is true but R is false.

D

Solution

Sunflower and Rose are bisexual flowers because they contain both androecium (carpels) and gynoecium (stamens).
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. The ovary is said to be inferior e.g., guava, cucumber.
