Where do the pollen grains of flowering plants develop?

a. in the anthers of a flower
b. in the carpels of a flower
c. while being dispersed by wind, water, or animals
d. within ovules
e. within pistils

Expert Solution & Answer

Summary Introduction

Introduction: The flowering plants are categorized under the group of “angiosperms”. The male reproductive system is called “stamen”. However, the female reproductive system is known as “pistil or carpel”. Pollen grains represents male gametophyte and ovule represents female gametophyte.

Answer to Problem 1TY

Correct answer: The pollen grains of the flowering plants develop “in anthers of the flower”. Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

The male reproductive part of the flower is stamen or androecium. Stamen is differentiated into filament and anther at the tip. The formation and development of pollen grains take place in the anther of the stamen.

Option a. is given as “in the anthers of a flower”.

In the anthers of the flower, the development of the pollen grains takes place. Hence, the correct answer is option a.

Reason for incorrect answer:

Option b. is given as “in the carpels of a flower”.

Carpel represents the female reproductive system, which bears female gametophyte and not the male gametophyte. Hence, option b. is incorrect.

Option c. is given as “while being dispersed by winds, water or animals”.

After the formation of pollen grains, it dispersed by winds, water, or animals. This process takes place after the development of pollen grains. Hence, option c. is incorrect.

Option d. is given as, “within ovules”.

The ovules represent the female structure of the female reproductive system of the flower. It gets fertilized by means of pollen grains. Thus, the formation of pollen grains does not takes place inside the ovules. Hence, option d. is incorrect.

Option e. is given as “within pistil”.

Pistil represents the female reproductive system of the flower and it contains ovules. Thus, the development of the pollen grains cannot be possible in pistil. Hence, option e. is incorrect.

Hence, the options b., c., d., and e. are incorrect.

Conclusion

The development of anthers takes place in the anther of a flower.

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW). If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?

None

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
