The male part of the flower is known as 

biology the living world of plants parts of flower and its functions flower to flower parts of a flower

  1. Filament

  2. Anther

  3. Stamen

  4. Pistil

Show answer
Correct Option: C
Explanation:

Stamens or androecium are the male reproductive part contains filament which is a slender stalk and anther is a bilobed structure which is responsible for the production of pollen grains (male gamete).

So, the correct option is 'Stamen'

The classification of the flowers as unisexual and bisexual is on the basis of 

biology the living world of plants parts of flower and its functions flower to flower parts of a flower

  1. Presence of flowers at the tip of plant

  2. Presence of anther and filament of plant

  3. Presence of stamen and pistil in the flower

  4. Both A and C

Show answer
Correct Option: C
Explanation:

Stamens or androecium are the male reproductive part and responsible for the production of pollen grains (male gamete). Pistil or gynoecium are the female reproductive part and produce ovum (female gamete). If both the organs are present it is called bisexual flower. If only one of them is present flower is referred to as unisexual.
So the correct option is 'Presence of stamen and pistil in the flower'.

Which part of the flower used in the formation of pollen tube?

biology the living world of plants parts of flower and its functions flower to flower parts of a flower

  1. Style

  2. Stigma

  3. Anther

  4. Filament

Show answer
Correct Option: A
Explanation:

  1. Carpels, pistil or gynoecium are the female reproductive part of the flower that consists of a stigma that holds the pollen grains, the style that leads the path of pollen tube and ovary produce ovum (female gamete). 
  2. Stamens or androecium are the male reproductive part contains filament which is slender stalk and anther is bilobed and responsible for the production of pollen grains (male gamete). 
So the correct option is 'Style'

Non-essential parts of flowers are

  1. Sepals and petals

  2. Sepals and carpels

  3. Sepals and gynoecium

  4. Androecium and gynoecium

Show answer
Correct Option: A
Explanation:

Non-essential parts of the flowers are the accessory parts that are not directly involved with the gametes formation and sexual reproduction. The whorls of the calyx (individual unit - sepals) and corolla (individual unit - petals) are involved in the protection of flower and attraction of the pollinators, respectively. So, these are considered to be non-essential parts of flowers.

Hence, the correct answer is 'Sepals and Petals'

Match column I with column II and select the correct option from the given codes.

A. Tallest flower (i) Maize
B. Pronuba moth (ii) Amorphophallus
C. Anemophily (iii) Salvia
D. Entomophily (iv) Yucca

  1. A-(ii), B-(iv), C-(i), D-(iii)

  2. A-(ii), B-(iv), C-(iii), D-(i)

  3. A-(iii), B-(ii), C-(i), D-(iv)

  4. A-(iv), B-(iii), C-(ii), D-(i)

Show answer
Correct Option: A
Explanation:

The tallest flower is amorphophallus which is commonly known as Rafflesia flower. It is known to be the largest flower in the world.

Pronuba moth and the plant Yucca have an interdependent relationship regarding the pollination. These are codependent on each other.
Entomophilous flowers are those kinds where pollination is done with the help of insects. The flower that are entomophilous are usually bright in colour to attract the insects. An example is salvia.
Anemophilous flowers are the one ones where the pollination takes place by the wind. The pollen grains are very light and the stigma is sticky and feathery so that they can catch the pollen grains. In maize, the pollination is anemophilous.
So, the correct option is 'A-(ii), B-(iv), C-(i), D-(iii)'

Which of the following options is correct?

botany flower to flower importance of pollination flower: parts of a flower flower and pollination

  1. Transfer of pollen grains from the anther to the stigma of the same flower-Autogamy

  2. Transfer of pollen grains from the anther of one flower to the stigma of another flower of same plant- Geitonogamy

  3. Transfer of pollen grains from the anther to the stigma of a genetically different plant of same species- Xenogamy

  4. All of these

Show answer
Correct Option: D
Explanation:
Autogamy is the transfer of pollen grains from the anther to the stigma of the same flower and genetically same type of pollens are brought to the stigma.
Pollination between two flowers of the same plant is called Geitonogamy. Xenogamy is the transfer of pollen grains from the anther to the stigma of a different flower of a different plant. Therefore, genetically different pollen grains are brought to the stigma.
So, the correct option is 'All of these'. 

The transfer of pollens from anther to stigma of the same flower is called as

  1. Cross pollination

  2. Self-fertilization

  3. Cross breeding

  4. Hybridization

Show answer
Correct Option: B
Explanation:

When a pollen grain from a stamen is transferred to the stigma of the same plant, it is called self-pollination. It mainly occurs in bisexual flowers.

So, the correct option is 'Self-fertilization'. 

In a flower, the male and female reproductive parts are ............. respectively.

botany flower to flower importance of pollination flower: parts of a flower flower and pollination

  1. Stamen and pistil

  2. Pistil and stamen

  3. Petals and pistil

  4. Stamen and petals

Show answer
Correct Option: A
Explanation:
Stamen and pistil are the male and female reproductive parts respectively.  Stamen has anther that produce pollen grains and stalk known as the filament. Pistil has stigma, style and ovary. The ovary contains egg-producing structures the ovules, the style, a hollow tube that receives the pollen tube and stigma that provides a platform for the pollen grains to land and germinate.
So, the correct answer is 'Stamen and pistil'.

Chasmogamy is pollination in.

botany flower to flower importance of pollination flower: parts of a flower flower and pollination

  1. Bud condition

  2. Closed flowers

  3. Open flowers

  4. Unrelated flowers

Show answer
Correct Option: C
Explanation:

Chasmogamy is a plant with a reproductive mechanism in which pollination occurs in chasmogamous flowers. Chasmogamous flowers are showy with open petals and encircling exposed reproductive parts.  Chasmogamous stems from Greek for an open marriage. These are named after the open arrangement of floral structures. 

Once chasmogamous flowers have reached maturity, they unfurl and their stamens and/or style are made available for pollinations correct answer is Chasmogamy, is pollination in open flower.

Thus the correct answer is C.
