Exam 28: The Life of a Flowering Plant

Unlike angiosperms, gymnosperms like pines have single instead of double fertilization, but otherwise have an identical life cycle. What structure should show the greatest difference between angiosperms and gymnosperms?

What constitutes the shoot system of a plant?

Scenario The North American beaver is a large rodent that builds dams to convert freshwater streams into ponds. Beavers build their dams out of trees, which they cut down using their front teeth. Beavers also eat the leaves and bark of trees, as well as the starchy roots of water lilies. -When a beaver is eating bark, what plant structures is it ingesting?

What are the tiny projections found on roots that increase the surface area?

A homeowner uses a nail to hang a "Home Sweet Home" sign on the trunk of an oak tree. The sign is 2 meters above the ground. The tree grows in height at a rate of 10 cm per year. How high above the ground will the sign be in 15 years?

Use this figure to answer the questions. -Examine the figure. Which structure has the same number of copies of chromosomes as the egg cell?

What list best characterizes the monocots?

What cells form chains with overlapping ends to form a system of water-carrying tubes, and are dead when mature?

The diploid number for the tomato, a eudicot, is 24. One of its pollen grains has ________ chromosomes, and the nutritive tissue of the seed has ________ chromosomes.

What is the primary function of typical leaves?

What describes the interdependence between flowering plants and animals?

These trees most likely grew in an environment with ________.

What is the single layer of tightly packed cells that cover the entire root?

The main parts of a flower are modified versions of ________.

Most domesticated food crops are ________.

Scenario In late 2006, bee workers in the United States started to notice a disturbing phenomenon: the sudden disappearance of honeybees from commercial hives. This mysterious condition was called "colony collapse disorder," and it has caused a drastic reduction in commercial honeybee populations all over the country. It is estimated that one-third of our food supply relies on bees and is in danger. Crops that rely most heavily on honeybees include apples, almonds, blueberries, and pumpkins. If colony collapse disorder cannot be cured or treated effectively, farmers may have to turn to other insects, perhaps other bee species or even moths. -Which plant structure is adapted for attracting beneficial insects such as honeybees?

What type of cells are most likely composing the dark ring of annual growth in the image?

Read the following scenario to answer the questions. The pineapple, grown for its sweet fruit, is a tropical monocot with a diploid number of 50. It can live for many years. The plant starts as one short stem with tough leaves. The flowers of the pineapple are located as a cluster at the very top of the stem. After pollination, the single fruit forms from the fusion of the ovaries of the flowers in the cluster. The seeds are located just underneath the surface of the fruit. The pineapple fruit is harvested by cutting at the base of the fruit. After the first fruit is produced, side shoots grow from the main stem, which can go on to produce additional fruits. -Where would we expect to find cells with 25 unpaired chromosomes in a pineapple plant?

Which statement CORRECTLY compares the growth of these two trees?
