Question

Flower with all the four types of floral organs is
(a)Regular
(b)Irregular
(c)Complete
(d)Perfect

Answer 1

Hint: The flowers with calyx, corolla, androecium, and gynoecium are flowers that mean ‘Total flower’. These flowers can undergo self-pollination. Rose, pea, hibiscus are some of the examples of these flowers.

Complete answer:
The complete flower has all the four whorls of calyx, corolla, androecium, and gynoecium. The flower is the reproductive part of the plant. It consists of a female organ (whorl) made of carpels (pistil/gynoecium), a male organ(whorl) made of stamens (Androecium), and a corolla made of petals, the usually attractive component often functions as a protective part of whorl-calyx, made of sepals, usually green but in many cases otherwise colored. If a flower has all these four whorls then it is called a complete flower. Complete flowers are bisexual flowers.
-Various terms are used to classify flowers depending on the presence and absence of the floral sections or the whorls.
-Perfect flowers are the ones with both sex organs.
-An incomplete flower is a flower without one or more floral whorls.
-The unisex flowers are dimorphic.

Additional Information: -Flowers grow in different shapes, sizes, and fragrances. However, all flowers have only one function helping a plant reproduce itself. Most flowers have reproductive organs, both male and female. The stamen is the part of male reproduction; the pistil is the part of female reproduction. Botanists call flowers that contain a functioning male part and a working female part perfect flowers.
Complete flowers (they are bisexual flower: have both male and female reproductive systems) and perfect flowers can undergo self-pollination. If a flower has both male and female reproductive parts and can produce its own fertilized seed, it is capable of self-pollination, meaning that it does not need gametes from other plants to reproduce. Examples of the perfect flowers are Tomatoes, lilies, mangoes.
-Flowers that only have one sex organ is called imperfect flower. If the stamen is absent, or underdeveloped, the flower is considered female. Such flowers are often referred to as pistillate flowers, as they have a formed working pistil but lack a working stamen. Those flowers that only contain a working stamen are called male, or stamina flower. Imperfect flowers will undergo cross-pollination (i.e.,) it requires gametes from other plants to undergo fertilization. Examples of the imperfect flowers are asparagus, spinach.
So, the correct answer is, ‘Complete’.

Note: The complete flower undergoes self-pollination that leads to genetic monotony. Also, self-pollination causes the defective trait to be carried to the next generation, and sometimes it weakens the plant variety by affecting the quality of the offspring.
