The main difference between autotrophs and heterotrophs is that autotrophs produce their own food using sunlight or chemical energy (e.g., plants and algae), while heterotrophs rely on consuming other organisms for energy (e.g., animals and fungi).
The main differences between photosynthesis and cellular respiration is that photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose, while cellular respiration is the process by which living organisms break down glucose to release energy in the form of ATP.
The main differences between Polytene and Lampbrush chromosomes is that polytene chromosomes are mainly found in somatic cells and are used for gene mapping, while lampbrush chromosomes are associated with meiotic cells and transcriptional activity.
The main difference between Genotype and Phenotype is that Genotype refers to the genetic makeup of an organism, including all of its genes and genetic information inherited from its parents whereas Phenotype is the observable physical and biochemical characteristics of an organism, such as its appearance, behavior, and physiological traits.
