-It can actually move as it has a flagellum. Movement is usually associated with animals
-It feeds on food whenever it needs to feed by engulfing the food with its body as our phagocytes do when the sunlight is not available

cyclosis is a regular cyclic movement of protoplasm within a cell. It is the circulation of cytoplasm or cell organelles , such as food vacuoles in some protozoans
3aiii )
peristalsis is the involuntary constriction and relaxation of the muscles of the intestine or another canal , creating wavelike movements that push the contents of the canal forward

I = incisors,C = canines,P = premolars,M = molars
For adult man it is
I:2 / 2,C:1/ 1,P:2/ 2,M:3/ 3
= 16 x 2 = 32

After the seed has made it to a new location and is covered with dirt , it can begin germination . Germination is the process of seeds developing into new plants . First , environmental conditions must trigger the seed to grow . Usually , this is determined by how deep the seed is planted , water availability , and temperature. When water is plentiful , the seed fills with water in a process called imbibition . The water activates special proteins , called enzymes , that begin the process of seed growth . First the seed grows a root to access water underground . Next , the shoots , or growth above ground , begin to appear . The seed sends a shoot towards the surface , where it will grow leaves to harvest energy from the sun
