Bisexual flowers are common in angiosperms, promoting reproduction efficiency.
Flower reproductive structure analysis:
(A) Asexual - Incorrect: Flowers with reproductive structures are by definition sexual.
(B) Unisexual - Incorrect: This describes flowers having either stamens (male) or carpels (female), not both.
(C) Bisexual - Correct: Flowers containing both stamens (male) and carpels (female) are termed bisexual or perfect flowers.
(D) Dioecious - Incorrect: This refers to plant species having male and female flowers on separate plants.
The correct answer is (C) Bisexual, also known as hermaphroditic or perfect flowers.
A flower with both stamens and carpels is bisexual .
Final Answer:
(C) Bisexual
Match the Column-I with Column-II and choose the correct option:
A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
