Compartmentalization of the cell means that there are structures inside the cell (within the cytosol) called organelles (nucleus, Golgi apparatus, endoplasmatic reticulum..) which are usually membrane-enclosed regions. Compartmentalization increases the efficiency of many subcellular processes by concentrating the molecules to a specific space within the cell. Each membrane-enclosed organelle has the characteristic position in the cytosol and specialized function in the cell.
Answer:
When the level of release of carbon dioxide during respiration and use of carbon dioxide during photosynthesis this results in a compensation point. At compensation point the net available carbon dioxide to phototrophs becomes zero. As, carbon dioxide is the chief ingredient for photosynthetic products like glucose and oxygen. These products are used up during the process of respiration. When the rates of two processes photosynthesis and respiration becomes equal. Phototrophic organisms will not be able to compensate for lack of carbon dioxide levels. Phototrophs will not be able to produce their food in the form of glucose and hence will not be able to respire too. This will result in lack of overall available food from phototrophs and lack of available oxygen for respiration. This will result in decline of organisms on earth.
Answer:scyphozoa
Explanation:cniderians are aquatic animals.they have radial symmetry, that is they can be divided into two halves through any plane.
Cniderians may have nematocyst,which are stinging cells.
They have two forms,which are polyp and Medusa .
There are four classes of cniderians;hydrozoa, scyphozoa,cubozoa and anthozoa.
Scyphozoa are predominantly medusa,which is umbrella shaped.they are jelly fishes.
They have four or eight oral arms.
They possess four gonads and four gastric pouches .an example is the Aurelia.
