Answer:
Cleavage, morula, blastocyst, gastrula
Explanation:
The zygote is formed after fertilization of sperm and ovum. Then the zygote undergoes a repeated cell division to form a number of cells. These tiny cells formed by mitotic cell division but present inside the zygote. It forms 2 cells then 2 cells, then 8 cells and so on. After forming the number of cells the zygote has a number of tiny cells. This stage is called morula and the tiny cells are called morulae. Then these cells migrate towards the periphery of the morula and creating a central space called blastocoel. This hollow ball structure is known as the blastocyst. After this blastocyst stage, the cells migrate to form 3 layers such as endoderm, mesoderm, ectoderm. From this layer different organs are formed. This 3 layered stage is known as gastrula. Thus the zygote development starts from cleavage, morula, blastula, and gastrula.
Answer:
Photorespiration is defined as a respiratory process in many higher plants in which plants take up the oxygen in the presence of light and produces carbon dioxide while in photosynthesis plants utilises sunlight and carbon dioxide to produce oxygen.
C4 plants able to photosynthesize with no apparent photorespiration because they use Phosphoenolpyruvate (PEP) carboxylase in order to fix CO2.
CAM plants keep the stomata closed throughout the day, thus reducing water loss.
Thus, Both reduce photorespiration but during carbon fixation they use more ATP and able to photosynthesize with no apparent photorespiration.
Chemical digestion refers to the process by which enzymes breaking down biomolecules into smaller units. These enzymes are secreted in the digestive tract.
- In chemical digestion, nutrient molecules are absorbed primarily in the small intestine and delivered to the BLOODSTREAM where they can be circulated to other cells in the body.
- Chemical digestion is able to degrade macronutrients into monomeric subunits by breaking down their chemical bonds.
- For example, lactose is a disaccharide that is degraded by chemical digestion into two monosaccharides (i.e., glucose and galactose) by the action of an enzyme called lactase.
- Subsequently, small nutrients can be absorbed into the bloodstream from the small intestine, thereby these nutrients are transported to all of the cells of the body through the blood vessels.
