Exam 25: The Angiosperms: Form and Function in Flowering Plants

A ring of vascular bundles in a stem is characteristic of:

Sepals are:

Double fertilization occurs within the embryo sac in the carpels of angiosperms.

Of the two basic structures of an angiosperm plant, roots are described as having the more straightforward function, while shoots have more complex functions. Evaluate and explain why this is true.

Vascular tissue that conducts water and minerals is the:

Refer to the scenario below, and then answer the following question(s). A friend of yours finds a plastic bag containing what appear to be similar seeds collected last year during a vacation hiking trip. Your friend isn't quite sure which plant he collected them from. You open the seed with a sharp knife, examine the inside, and ask him if it was a non-woody plant with narrow leaves. Now recalling the plant, and astonished by your "detective work," he says, "Yes! How did you know?" Your friend then presents several pressed flowers and states that one of the flowers was from the plant from which he collected the seeds, but he isn't exactly sure which one. You examine the petals and sepals of each flower. The first flower has six parts, the second has five parts, and the third has eight parts. -How did you know by examining the seed that it was a non-woody plant with narrow leaves?

Companion cells are specialized cells found in which plant tissue?

Because a plant can grow indefinitely at the tips of the roots and shoots, we say that a plant's growth is:

The major advantage provided to plants by root hairs is:

Match the following. A) connects leaf to stem B) catches pollen C) open and close stomata D) conducts food E) produces pollen -Guard cells

The male gametophyte generation develops largely within pollen grains of angiosperms.

After pollination, sperm cells travel through the carpel in a structure called the ________.

Vascular bundles are found in monocot stems but not in dicot stems.

Vascular tissue that conducts food produced during photosynthesis is the:

Which plant tissue contains cells called tracheids?

A fibrous root system is made of roots that are all about the same size.

A flower's nectar is food for pollinators, so one might question whether fruit is also an adaptation for attracting pollinators. Which of the following would be the most valid fact supporting the hypothesis that fruit is for encouraging seed dispersal rather than to encourage pollination?

Stomata allow carbon dioxide into a leaf and water vapor out.

Match the following. A) connects leaf to stem B) catches pollen C) open and close stomata D) conducts food E) produces pollen -Anther

Which flower would you select as the one matching the plant from which he gathered the seeds?
