Answer:
Explanation:
Cellular respiration generally involves breaking down of large organic molecules to release ATP (energy). Citric Acid cycle, also known as Kreb's cycle or Tricarboxylic acid cycle is the second stage of the cellular respiration (unique to aerobic organisms). Citric acid cycle occurs in the intracellular space or matrix of the mitochondria of eukaryotes.
Glycolysis, which is the first step of cellular respiration, produces pyruvate which is then converted to Acetyl CoA in order to enter the Kreb's cycle by first combining with oxaloacetate. Generally, citric acid cycle involves an eight-steps reaction consisting of series of reduction-oxidation, hydration, dehydration, decarboxylation reactions, with each step catalyzed by different enzymes.
In a nutshell, oxaloacetate is generated back at the completion of the cycle alongside 2 molecules of CO2, one GTP/ATP molecule and electron donors; NADH2 and FADH2. These reduced electron donors enter the third step of aerobic cellular respiration and act as the first electron donor in the Electron transport chain.

Differentiation in plants refers to the processes by which distinct cell types arise from precursor cells and become different from each other. Plants have about a dozen basic cell types that are required for everyday functioning and survival. Additional cell types are required for sexual reproduction. While the basic diversity of plant cell types is low compared to animals, these cells are strikingly different. For example, some cells such as parenchyma cells retain the potential to respond to environmental and/or hormonal signals throughout their life and, under the right conditions, can be transformed into another cell type (transdifferentiation). Other cells such as the water-conducting vessel elements undergo cell death as part of their differentiation pathway and thus can never transdifferentiate to another cell type
