Exam 23: Seed Plants: Angiosperms

In this question, assume that the life cycle of a flowering plant begins with the germination of a seed and ends with the development of a fruit.Two events that occur in the life cycle are the formation of polar nuclei and the formation of megaspores.

Which of the following pollinators rely more on vision than on smell in seeking floral energy sources?

Flowers with well-developed landing platforms and nectar guides would probably be pollinated by

Which of the following is NOT a structure or event associated with orchids and their pollination?

A flower with dull green petals, copious amounts of pollen, and long styles with feathery stigmas would be pollinated by

The diversity and number of species of angiosperms is due, in part, to the partnership with animals to aid in pollination and seed dispersal.

The ovary of the flower matures into a(an)

Which of the following is considered to be a specialization characteristic of advanced (more highly evolved)flowering plants?

Which of the following tissues or structures in flowering plants is a part of the gametophyte generation and therefore haploid?

Angiosperms differ from conifers in all of the following EXCEPT

The mature male gametophyte of an angiosperm consists of ___________________.

In this question, assume that the life cycle of a flowering plant begins with the germination of a seed and ends with the development of a fruit.Two events that occur in the life cycle are the formation of a tube nucleus and the formation of sperms.

Pollen is produced in this flower part.

In this question, assume that the life cycle of a flowering plant begins with the germination of a seed and ends with the development of a fruit.Two events that occur in the life cycle are the formation of endosperm tissue and the development of an embryo.

Bats and other mammals are pollinators of some flowers.

Parthenocarpy involves fruits that develop from ovaries containing unfertilized eggs.

Each microspore mother cell normally divides to form four pollen grains.

Botanists preserve plants for future reference and study as part of the research collection in a/an ______________.

The unique products of double fertilization in angiosperms are ________________.
