D. Cytoplasm
E. Cell membrane
Answers
chloroplast is only in plants
lysosomes are mostly in animal
cell wall is plants
cytoplasm is plants and animals
ans so is cell membranes
The structures found in all cells are cytoplasm and cell membrane, which are present in options D and E because these are the basic characteristics of the cell, whether unicellular or multicellular.
What is the significance of the cell cytoplasm and cell membrane?Cytoplasm and cell membrane are two essential structures present in all cells and maintain the cell's structural integrity while performing various cellular functions, while cytoplasm is the gel-like substance of the cell and contains the cell's organelles, enzymes, metabolic intermediates, etc.
Hence, the structures found in all cells are cytoplasm and cell membrane, which are present in options D and E because these are the basic characteristics of the cell, whether unicellular or multicellular.

Photosynthesis and cellular respiration differ in which of the following
ways?
O The main source of chemical energy in cellular respiration is water.
The energy conversion in cellular respiration takes place in the chloroplast.
O The main source of energy in cellular respiration is glucose.
The final product of cellular respiration is electromagnetic radiation.
Answers
Answer:
the main source of energy in cellular respiration is glucose.
Explanation:
photosynthesis creates glucose out of co2 h2o and sunlight. while cellular respiration is almost exactly the opposite.
The ways in which photosynthesis and cellular respiration differ is that the main source of energy in the case of cellular respiration is glucose. Hence, Option C is the correct answer.
The photosynthesis and cellular respiration processes are interlinked with a significant relationship. The products of one process act as reactants in the other. Some of the significant differences between both processes are mentioned as follows:
Photosynthesis takes place only in phototrophs such as plants and algae while cellular respiration can take place in all the living forms. Photosynthesis completely takes place in chloroplasts and cellular respiration in Mitochondria. Glucose is made by the process of photosynthesis while glucose is utilized in cellular respiration to make molecules of ATP.Thus, we can conclude that photosynthesis and cellular respiration differ specifically by the main source of energy. Hence, option C is the correct answer.
