Exam 28: The Life of a Flowering Plant

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. -Water lily shoots and roots have very little structural support because this support is not needed in aquatic habitats.What structures would you be LEAST likely to see in a water lily stem?

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. -Which plant structure is adapted for attracting beneficial insects such as honeybees?

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

Flowering plants reproduce through ________.

Which of the following best describes the primary function of typical leaves?

Which of the following are the most abundant cell type found in most plants?

Which of the following describes the single layer of tightly packed cells that cover the entire root?

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. -When a beaver is eating bark,what plant structures is it ingesting?

Which of the following plant types complete their life cycle in 2 years?

Examine the figure below.What process has to occur to produce a haploid embryo sac?

Which of the following is the part of a flower that contains the female reproductive structures?

Which of the following is the waxy coating secreted on leaves and most stems?

The ________ enclose and protect the flower bud,while the ________ advertise the flower to insects and other pollinators.

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. -What evidence best supports the pineapple's classification as a monocot?

A plant's diploid form is called the ________; the haploid form is called the ________.

In a sporophyte of an angiosperm,growth occurs at ________ via ________.

A tree grows wider each year because of ________. I)apical meristem II)vascular cambium III)cork cambium

While on a hike,you notice that several burrs have become attached to your socks.You quickly pull them off.Inside the burr are several seeds.Burrs are produced by certain plants and frequently catch on animal fur (or people's clothing).After thinking about it,you decide that the burr is a type of ________ that is an adaptation for ________.

Which of the following is a multicellular mass that nourishes the embryo until it becomes a self-supporting seedling?

Please refer to the following art of the cross-sections of two trees to answer the following questions. -These trees most likely grew in an environment with ________.
