In general, there are three types of Cell division :
- Binary fission, a division process on which a cell is completely cloned, forming 2 exact same cells
- Mitosis , a division of a somatic cell of Eukaryotic organisms
- Meioses, a cell division that produces gametes

Answer:
The cell membrane separates the external and internal environment of the cell. The cell membrane is composed of bilayer lipids, proteins and small amount of carbohydrates.
The lipid part is soluble in hydrophobic environment or with the hydrophobic part of other phospholipids because like molecules dissolve in like molecules. The hydrophobic part is non polar and hydrophilic parts is able to dissolve in polar area due to the interaction of same molecules with each other.
Answer:
Explanation:
Two reactions take place that produce raw materials for the dark stage:
- Light energy splits the water molecules into <em>hydrogen</em> and <em>oxygen</em>
- This process is called <u>photolysis </u>
The hydrogen is taken up by a hydrogen acceptor called Nicotinamide adenine dinucleotide phosphate (NADP) while oxygen is released as a by-product .
2 H₂O(l) --------->light energy -------> 4 H + O₂ (photolysis
)
Light energy strikes the chlorophyll molecules and sets in motion a series of reactions resulting in the production of a high energy molecule called <em>Adenosine Triphosphate</em> (ATP)
