Compare the meristematic tissue with the cancerous cells
solniwko [45]
Meristematic tissue have the ability to divide themselves. It is the primary site for cell division and cell differentiation. It produces the new cells and are called growing tissue in plants. The new cells may or may not divide. It is the source of the regenerative potential of the plant.  
<span>
Cancerous cells can originate anywhere in the body and can spread into or invade adjoining tissues. It keeps growing and dividing relentlessly to form lumps. It can also break off and travel to distant tissues. Cancer cells rejects signals from other  cells.</span>

Explanation:

Interphase is the most important phase of cell life cycle where it spends 90 percent its time in regulating the metabolic activities of the cell. In this phase cell undergoes several metabolic activities to maintain the growth of the cell.

The net primary production of a pine forest on a lava flow on Mount Fuji is about 165,000 kcal/m2/yr, and the plant respiration
IceJOKER [234]

Answer:

<em>The total amount of energy transferred during photosynthesis for this ecosystem equals</em><em> 260,000 kcal/m2/yr.</em>

Explanation:

To answer this question, we need to know that  

  • gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesis
  • net primary productivity (NPP) = difference between GPP and respiration rate

So, to calculate GPP we need to sum NPP to Respiration rate. This if,

NPP = 165,000 kcal/m2/yr

R = 95,000 kcal/m2/yr

NPP = GPP – Respiration

Then,

GPP = NPP + R

GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr

GPP = 260,000 kcal/m2/yr
