Answer:

storage of water and developmend of thorns

Explanation:

The cactus is the best example of a plant that has adapted very well to the desert.

The first adaptation has to do with water storage. Thanks to the long roots it has, it can absorve water from very deep areas. The water stored is stored in adapted vacuoles. The cells of the cactus are adapted to transpirate as little as possible, no to loose water in evatranspiration process.

The second adaptation has to do with it´s thorns. Big, rigid and pointy thorns are the perfect defense tolive in the dessert. Animals will tend to eat plants which will not harm them at all. This is why, thorns are a great protection against hungry eaters.

They assemble settles by unearthing pits in old pine trees in the Southeast, which was an incredible transformative system until individuals cleaved down 97 percent of their natural surroundings.
<em> Snakes are a portion of their most risky home predators</em>, so the <em>winged animals peck the pine trees' bark </em>to make sap overflow down the tree trunk. The smooth of sap stops winds and protects the nest cavities above.
Each pine tree in a backwoods into timber or turpentine, it sets aside a long effort for trees to become large enough to help respectable size home depressions.

Answer:

Explanation:

1)Pfr/Pr

2) Pr

3)far-red

Explanation:

The leaves at the top of a tree’s canopy are exposed to direct sunlight during the day, and their phytochromes will occur in a high *Pfr/Pr* ratio. Meanwhile, the leaves of the same tree at the bottom of the canopy are highly shaded during the day and will likely have a higher proportion of the * ( PHYTOCHROME )Pr *;form of phytochrome present due to exposure to a higher proportion of *FAR RED * light.

Plants make use of the phytochrome system to it's adjust growth based on the seasons. Through phytochrome plants is able to respond to the timing and duration of dark and light periods. At dawn, all the phytochrome molecules present in the leaved are converted to the active Pfr form until sunset this is because the sun is unfiltered, and unfiltered sunlight has high percentage of red light, but lower far-red light, with the help of phytochrome system , the plants is able to compare the length of dark periods over several days.
