Mesophyll cells are primarily responsible for:

Refer to the figure below, and then answer the following question(s). -The missing label indicated by a "1" corresponds to the:

You find a leaf that has large stomata and a thick,waxy covering.What is clear about the original plant?

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?

Which statement best describes the role of the megaspore in angiosperm reproduction?

Which kind of root system consists of a large central root and numerous lateral roots?

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

Companion cells play a role in keeping xylem cells alive.

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

The anther in a flower produces microspores.

Which of the following best describes the nature of the cells of mature,functioning xylem?

Woody plants exhibit secondary growth in addition to primary growth.

Although they produce flowers,cacti with needle-like leaves would be classified as gymnosperms rather than angiosperms.

The male gametophyte generation of angiosperms is represented by:

The two basic divisions of the "body" of an angiosperm plant are ________ and ________.

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

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

Describe how the broad leaf of a typical dicot is so well adapted for its job as the photosynthetic organ of a plant.In your answer make sure to assess the ways plants evolved to deal with potential problems the broad leaf might cause.

The trap of a carnivorous plant such as the Venus flytrap is what plant structure?

Evaluate and explain this statement: An angiosperm plant could be described as the ultimate "solar energy organism."
