Match each organism with its phylum Pines Ephedra Palm-like plants Trees with fan-shaped leaves A. Gnetophyta B. Ginkgophyta C.
solong [7]

Answer:

Ginkgophyta

Explanation:

Gymnosperms are cone-bearing trees or Woody plants, which do not different greatly in their structure from the Woody angiosperms. Gymnosperms do not produce flowers but as seed plants that bear their seeds on scale-like leaves which are arranged spirally to form cones. The seeds are termed naked seeds because they are exposed to the air on the surfaces of the cone scales.

Gymnpsperms are grouped into four major divisions namely:

*Ginkgophyta

*Cycadophyta

*Corniferophyta

*Gnetophyta

1)DIVISION GINKGOPHYTA:The ginkgo tree cared maiden hair is the only surviving member of this division. It is found in the Orient(China and Japan) where it is cultivated as an ornamental tree because of the fan-like leaves. The leaves are *fan-shaped* with long petrioles.

2)DIVISION CYCADOPHYTA:The cycads abound in the tropics, mainly as ornamental plants. They are *palm tree-like* plants with a crowded crown of palm fronds.The leaves of Cuba's are deep green,waxy with large petioles.

DIVISION CONIFEROPHYTA:This is the largest group of Gymnosperms as it includes some of most economically exploited plants such as *pines* and Jupiter's. The pine tree is important as Christmas tree and conifers are generally important in the production of wood and paper

DIVISION GNETOPHYTA:This is the group of very unique Gymnosperms made up of three genera:Gnetum,*Ephedra* and Welwitschia.

Ephedra is a profusely branched shrub found in desert regions. It has whorl-like, scale-like, or needle -like leaves and jointed stem.

Hence, matching each with its phylum, we have:

Gingkophyta:Fan-shaped leaves

Cycadophyta-Palm-like leaves

Coniferophyta:Pine

Gnetophyta:Ephedra

The ara operon is controlled by a regulator protein that exerts ________.
goblinko [34]

AraC protein certain to the ara operator works as a repressor that avoid transcription of the same ara operon and the araC gene AraC protein is an activator in the presence of arabinose and repressor in the absence of arabinose -With arabinose absent, the AraC protein stays as
a homodimer. One AraC protein put together to the ara initiator and the other protein now binds to a different regulatory site in DNA called the ara operator.
