Flowers Practice Problems

19 problems

According to the ABC model of flower development, the interaction between class A and ______ genes affects the development of petals.

2PRACTICE PROBLEM

Insect pollinators help to keep the ecosystem together by sustaining and promoting plant reproduction and variety, which is critical for the survival of other organisms, including humans. As a result, pollinators are regarded as:

3PRACTICE PROBLEM

Hibiscus can self-pollinate by having their pollen transferred to the stigma pads of the pistil, the female organ of the flower. Inside the plant's ovary are _____ that develop into seeds upon fertilization.

4PRACTICE PROBLEM

Due to the absence of gene flow and genetic variations, self-pollinated plants have reduced biological fitness compared to cross-pollinated plants. They are susceptible to diseases affecting plant yield. Thus, self-pollination among plants can lead to:

5PRACTICE PROBLEM

Which of the following characterizes cross-pollinated plants?

6PRACTICE PROBLEM

For plants that rely on wind for dispersal, how is their pollen adapted to wind pollination?

7PRACTICE PROBLEM

Which of the following plants will likely attract fewer pollinators?

8PRACTICE PROBLEM

Which of the following statements is true about self-fertilized plants?

9PRACTICE PROBLEM

In angiosperms, microspores are produced by meiotic division inside the microsporangium. After pollination, the microspore germinates to form the male gametophyte which is:

10PRACTICE PROBLEM

The endosperm is a tissue that develops within the seeds of the majority of flowering plants following double fertilization. What is the main role of the endosperm in the life cycle of angiosperms?

11PRACTICE PROBLEM

Both the male and female plants have the same genotype, which is Tt. How will the double fertilization process affect the genotypes of the embryo and endosperm nuclei?

12PRACTICE PROBLEM

In a plant showing sporophytic incompatibility which one of the following crosses is successful in producing a zygote?

13PRACTICE PROBLEM

One of the sperm is needed to fertilize the egg, and a second sperm is needed to fertilize the polar nuclei, this process is referred to as

14PRACTICE PROBLEM

Which one of the following is incorrectly matched with respect to flower and type of pollination:

15PRACTICE PROBLEM

Which one is incorrectly matched with reference to the parts of flower:

16PRACTICE PROBLEM

Which statement is true regarding the ploidy level of the embryo, endosperm, and double fertilization?

17PRACTICE PROBLEM

All of the following statements on asexual plant reproduction are accurate, with one exception.

18PRACTICE PROBLEM

In Angiosperms, during double fertilization, an endosperm is formed by the fusion of

19PRACTICE PROBLEM

_____________ is the pollen-producing part of the flower.
