Chapter 30, Problem 1TYU

A seed develops from an

A. ovum
B. embryo.
C. ovule
D. ovary

Expert Solution & Answer

Summary Introduction

Introduction:

A seed is defined as an embryonic plant, which is enclosed within a protective covering (seed coat). New plants germinate from the seeds and thus, seeds are an essential part in the reproductive process of plants.

Answer to Problem 1TYU

Correct answer:

Seeds are formed when fertilization takes place in the flowers. The ovules develop into seeds. Therefore, option (C) is correct.

Explanation of Solution

Reasons for the correct statement:

Seeds are also called ripened ovules. This is due to the fact that they are made from ovules after fertilization.

Option (C) is given as “ovule”.

As “seeds are made from ripened ovules”, it is the right answer.

Hence, option (C) is correct.

Reasons for the incorrect statements:

Option (A) is given as “ovum”.

Ovum refers to egg. It is the female sex gamete in oogamous individuals. Eggs do not develop into seeds. So, it is a wrong answer.

Option (B) is given as “embryo”.

An embryo is formed when a zygote (fertilized egg cell) develops. So, it is a wrong answer.

Option (D) is given as “ovary”.

After fertilization, ovary develops into fruit. So, it is a wrong answer.

Hence, options (A), (B), and (D) are incorrect.

Conclusion

Seeds are a result of reproduction. Seeds form when the ovules are fertilized by the male gametes. The ovary develops into the fruit and the ovules develop into seeds. These processes take place post the fertilization event.

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…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
