In flowrers, the structures that produce male gametophytes are called ______; the structures that produce female gametophytes are called _______.

  1. a. carpels; stamens
  2. b. pollen grains; flowers
  3. c. anthers; carpels
  4. d. megaspores; microspores

Summary Introduction

Introduction: A flower is the reproductive part of the modified thick shoot of an angiosperm plant. A stamen consists of an anther and a filament, which are the male reproductive parts of a flower that produce the male gametophyte. Carpel is the female reproductive part of a flower. It usually consists of a style, stigma, and ovary. A structure in which many carpels are fused together is known as a pistil. Some species consists of one carpel while others contain many carpels.

Explanation

Reason for the correct answer:

Stamens are the male reproductive part of the flower which consist of anthers and filaments. Anthers help to produce pollen grains.

Carpel is the female reproductive part of a flower that produces the female gametophytes. It usually consists of a style, stigma, and ovary. A structure in which many carpels are fused together is known as a pistil. Their main functions are to collect pollen grains for the pollen germination, connecting the stigma to the ovary and producing the fruit by the fertilization process, respectively. A part of the carpel which carries the female gametes is called an ovule.

Option b. is given as “anthers; carpels”.

Stamens are the male reproductive parts of the flower which consist of anthers and filaments. Anthers help to produce pollen grains. Carpels are the female reproductive parts of a flower.

Hence, the correct answer is option b.

Reasons for the incorrect answers:

Option a. is given as, “carpels; stamens”...
