The Inflorescence

The video tutorial explains the structure of flowers, focusing on inflorescence types in angiosperms. It covers racemose inflorescence, including rassim, spike, catkin, spadix, corymb, umbel, and capitulum. It also discusses cymose inflorescence types like monochasial, dichasial, and polychasial, and special inflorescence types such as hypanthium, syatem, and verticillata.

What is the main function of the floral meristem in angiosperms?

• To produce seeds

• To absorb nutrients

• To form a flower

• To support the plant

Which type of inflorescence is characterized by flowers that are sessile and arranged on a fleshy axis?

• Raceme

• Spike

• Spadix

• Corymb

In which type of inflorescence do flowers originate from a common node and resemble an umbrella?

• Umbel

• Capitulum

• Spike

• Corymb

What distinguishes a helicoid cyme from a scorpioid cyme?

• The flowers are sessile

• The main axis continues to grow

• The main axis terminates in a flower

• The lateral branches arise alternately

Which plant species is an example of a dichasial cyme?

• Ficus

• Calotropis

• Dianthus

• Begonia

What is a unique feature of the hypanthium inflorescence?

• It has a spherical receptacle with a cavity

• It is a pendulous inflorescence

• It has a flat top cluster of flowers

• It is a racemose inflorescence

In which type of inflorescence are flowers arranged in pairs opposite to each other at each node?
