Yes, there indeed may be more holes on the north side of a saguaro cactus (Carnegiea gigantea or Cereus giganteus).
Specifically, the south side of a cactus gets the most sun. Water loss therefore is bound to occur every time that a breathing pore, or stoma, opens up. As a result, the cactus tends to carry important regulatory activities through a greater number of pores out on its northerly side to protect internal water reserves.
Yes too, there may be more holes in terms of those caused by predators. The Gila woodpecker (Melanerpes uropygialis) and the red tailed hawk (Buteo jamaicensis) particularly favor the saguaro cactus as a nesting site. They like saguaro nesting cavities as much as other wildlife enjoy the nesting holes in a deciduous tree. They nibble their way through the saguaro's thickened outer covering to access the fleshy, juicy, succulent tissue on the inside of the stem. On the north side, they satisfy their needs for room and board without having to worry about water loss drying out their food source.
Because roses need more water than cactuses. A cactus can store water in itself.
Cactuses.. really i need more
I believe a Saguaro needs more water. I found this web site very informative on Catus. <a href="http://linkjacket.com/jk.cgi?i=7mex03E&d=http%3A%2F%2Fwww.life123.com%2Fhome-garden%2Fplant-guides%2Fcactus%2Fgrowing-saguaro-cactus.shtml&n=NaN" target="_self">Saguaro or a Prickly pear</a>
The Saguaro (Carnegiea gigantea) is considered mature at 100-125 years old. Older specimens may attain ages of 200 years or more
The Saguaro cactus is found in the Sonoran desert in the south west of continental North America. There are no other places that the plant grows naturally. For more information please check out the related links below.
Carnegiea gigantea is a tall cactus that's native to the southwestern United States of America. The cactus' common name is the giant saguaro cactus. The plant also is native to northwestern Mexico.
He will not take it very lightly
Cactuses are actually found all over, but more commonly in the Southwestern deserts. Most people think that they do well in very dry conditions, but the desert is actually quite rainy at times, and cactuses being succulents, excel at storing water. They don't grow well in very dry places.
Definitely South. It is longer and the wind plays role on more holes.
more holes
No, not all cactuses have spines. Some cactus plants have many more than others. Some have longer or shorter, finer or thicker spines. Some have white spines, some colored. And some don't have any spines at all.
so they can store more water when it rains and this is where Photosynthesis takes place
