Inflorescence
Edible part of the cauliflower is inflorescence which can be defined as the arrangement of flowers on the plant. Cauliflower is the member of family Brassica. Only the head part of cauliflower is eaten which is composed of a white inflorescence meristem.
Inflorescence having unisexual sessile flowers is
-
Spike
-
Spikelet
-
Catkin
-
Raceme
A catkin is a slim, cylindrical cluster of flowers with no petals, usually wind-pollinated and sometimes insect pollinated. The female flowers in catkin are sessile and solitary in the axilla of a bractea longer than themselves. In spike, flowers are bisexual, sessile or non- pedicellate. In spikelet, flowers are hermaphrodite. In raceme, flowers are pedicellate an bisexual.

-
Spadix
-
Compound spadix
-
Compound spike
-
Compound corymb
- The type of inflorescence in which flowers are protected by enveloping bracts known as a spathe. ex:-banana.
- The flowers are protected by spathe but the axis is branched. ex: palm and coconut.
- The axis is branched and the flowers are born sessile on the branches. ex: wheat.
- When the main axis is branched and flowers are arranged in a corymbose manner. ex:-cauliflower
Axis between corolla and androecium is
-
Anthophore
-
Gynophore
-
Gynandrophore
-
Androphore
The axis or the internode that elongates between the corolla and androecium is called androphore. It is also called as gynandrophore. Anthophore is present between calyx and corolla. Gynophore is present between androecium and gynoecium.
A student observed $34$ inflorescence in Bougainvillea and $42$ inflorescence in Poinsettia. Find out the number of flowers in Bougainvillea and the number of female of flowers in Poinsettia respectively.
-
$34, 126$
-
$204, 164$
-
$102, 42$
-
$68$, indefinite
The inflorescence in the Bougainvillea flower is a simple cyme or cymule. In the cymule, the peduncle ends in a flower and only 2 lateral branches. These are produced which also ends in flowers. Thus, 3 flowered inflorescences will be formed. Flowers are arranged in a basipetal manner. Since the inflorescence number will be given here 34. Thus, the total numbers of flowers would be $34 \times 3 = 102.$
Single female flower-like inflorescence of the Euphorbiaceae i.e. Poinsettia is called a cyathium. The single female flower of cyathium has 3 carpels syncarpous pistil. Also, the inflorescence number given here is 42. Thus hence the number of female flowers is 42.
So, the correct answer will be 102,42.
The correct option is C.
Cup-like structure developed from adnation of sepals, petals and stamens is
-
Cyathium
-
Hypanthodium
-
Hypanthium
-
Capitulum
Hypanthium is the cup-like structure that develops from the fusion of sepals petals and stamens to the thalamus outgrowth and it is seen in the family Rosaceae.
Consider the following statements.
(a) In racemose inflorescence the flowers are borne in a basipetal order.
(b) Epigynous flowers are seen in rose plants.
-
A and b are true but c is false
-
A and c are true but b is false
-
A and b are false but c is true
-
B and c are true but a is false
-
A and c are false but b is true
(a) In the racemose type of inflorescence, the youngest flower is borne near the apex and the oldest is borne at the base of the inflorescence. This is called the acropetal order. Basipetal order is seen in the cymose inflorescence.
