BIO 113 Unit #2 TEST REVIEW

Hormones Plant Structure Transport in plants A ngiosperm reproduction Odds & Ends

These openings on the leaf surface allow for gas exchange.

100 What are STOMATA?

Heartwood and Sapwood consist of: A)Bark B)Cork C)Secondary Phloem D)Secondary Xylem

200 What is D) SECONDARY XYLEM?

These cells function as support elements for plants and often have lignin in their cell walls.

300 What are SCLERENCHYMA cells?

Plants have three basic tissue systems, including dermal tissue and vascular tissue. The third tissue system which includes a variety of cells with specialized functions is called…

400 What is GROUND TISSUE?

Sieve-tube elements are cells found in this plant tissue.

500 What is PHLOEM?

This network of vessels allows for the transport of water and minerals.

100 What is XYLEM?

The cytoplasms of plant cells are continuous from cell to cell. This allows materials to move through plant tissue by the “cytoplasmic continuum”. This transport route is called…..

200 What is the SYMPLASTIC route?

These specialized channels through the cell membrane enhance the passive diffusion of water across the membrane.

300 What are AQUAPORINS?

Root pressure may result in more water entering leaves than is transpired. This can cause water to be exuded from leaves. This process is called…

400 What is GUTTATION?

This waxy material in the cell wall of endodermal tissue blocks apoplastic transport into vascular tissue.

500 What is the CASPARIAN STRIP

Double fertilization results in a fertilized egg (zygote) and this triploid structure.

100 What is ENDOSPERM?

Fruit develop from this structure

200 What is the OVARY?

The embyronic root is called …

300 What is the RADICLE?

Seed germination depends upon this process in which water enters the seed

400 What is INBIBITION?

In monocots the early shoot arising from the seed is sheathed in a structure called…

500 What is the COLEOPTILE?

Fungi live in association with the roots of most plants. The association where the fungal hyphae extend into root tissue is called…

100 What is ENDOMYCORRHIZAE

The bacterial genus Rhizobium lives in association with plant roots and provides the plant with an important resource via this process

200 What is NITROGEN FIXATION?

Which of the following elements is not a micronutrient: Iron, Zinc, Carbon, Copper

300 What is CARBON?

This receptor responds to light and regulates many of the plant’s responses to light throughout its life.

400 What is a PHYTOCHROME?

Systemic Acquired Resistance (SAR) is triggered by this signal molecule

500 What is SALICYLIC ACID?

This plant hormone is used commercially to increase fruit growth. (Think “Thompson seedless green grapes”)

100 What is GIBBERELLIN?

The “Triple Response to Mechanical Stress” is mediated by this hormone.

200 What is ETHYLENE?

This hormone is active in plant responses to drought.

300 What is ABSCISIC ACID?

This hormone promotes root formation and is found in commercially available “rooting compounds”.

400 What is AUXIN?

Seed germination is mediated by this hormone.

500 What is GIBBERELLIN?
