How tall is Shaquille O'Neal. American basketball player. He has stated 7ft 1 as his height. He was measured just under the mark, although DraftExpress noted that he was supposed to have been measured 7ft without shoes in 1992 and it is possible he was near 7ft 1 in shoes..
With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body.Carbon dioxide passes from the blood through the thin gill tissue into the water.Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians.n the larval dragon fly, the wall of the caudal end of the alimentary tract (rectum) is richly supplied with tracheae as a rectal gill, and water pumped into and out of the rectum provides oxygen to the closed tracheae.
In the root, the xylem (stained green-blue in the photo) are arranged. in some sort of star or cross-shape. The phloem tissue are arranged in. smaller groups in between each spike of the xylem cross-shape. Around the bundle is a special layer of cells called the endodermis. This has. a key role in getting water to the xylem vessels. Inside the endodermis is a. layer of meristem cells called the pericycle. The vascular bundles are found near the outer edge in. the stem. The xylem is found towards the inside of. each vascular bundle (see the diagram), and the. phloem towards the outside. In between the xylem and the phloem vessels there is a layer of cambium. This is a layer of meristem cells which can divide to produce more phloem or xylem. The diagram to the right (top) shows a vascular bundle in close detail. The below diagram shows a transverse section of a stem, where you can see the entire outer ring
