Exam 28: The Life of a Flowering Plant

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

What is the likely effect of pruning a plant at the dotted line?

Read the following scenario to answer the following questions. 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. -As a beaver chews from the outside to the inside of a tree,in what order does it encounter plant tissues?

Which of the following best describes the condition in which the terminal bud of many plants produces hormones that inhibit growth of axillary buds?

Scenario Questions Read the following scenario to answer the following questions. 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. -Without honeybees,which process in the life cycle of plants such as apples,almonds,blueberries,and pumpkins is most affected?

Read the following scenario to answer the following questions. 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. -Beavers dams are sturdy,because the part of a tree that provides structural support when the tree is alive lends its strength to the dam,even after the tree is dead.What part of a tree provides this structural support?

Please refer to the following art of the cross-sections of two trees to answer the following questions. -How old are these trees?

Which of the following do guard cells act to regulate?

Bermudagrass is a plant that is commonly used on golf courses.It has a fibrous root system,and its leaf veins are parallel.Because it is mowed on a regular basis in golf courses,it spreads via horizontal stems that root at the nodes,rather than by seed.It can live for many years.What is the best classification for bermudagrass on a golf course?

Which of the following contains the developing egg and cells that support it?

Which of the following have thick secondary cell walls strengthened with lignin,and support plants like steel beams in a building?

Which of the following are the tiny projections found on roots that increase the surface area?

Which of the following is an example of flowering plant/animal interdependence? I)Most angiosperms depend on insects,birds,or mammals for pollination. II)Most angiosperms depend on insects,birds,or mammals for seed dispersal. III)Most land animals depend on angiosperms for food.

Which of the following best characterizes the eudicots?

Which of the following is responsible for the increase in girth (width)of trees?

Which of the following form tubes and are alive when mature?

Read the following scenario to answer the following 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. -The first pineapple on a plant develops from ________,whereas the pineapples from the second harvest of the same plant develop from ________.

The main parts of a flower are modified versions of which of the following?

In which structure do pollen grains develop?

The arrows in the figure below illustrate ________.
