Scientific method is a continuous process. This process starts with the observation of a certain phenomenon. Based on what is observed, a hypothesis is develop to describe this phenomenon. This hypothesis is then tested by experiments where the results of these experiments either confirm or contradict the developed hypothesis.
If the hypothesis is contradicted by the results of the experiment, then another hypothesis is developed and tested for either confirmation or contradiction.
Based on this, any question that cannot be tested and studied experimentally cannot be solved using scientific methods.
Answer:
The major differences between the plant cell and animal cell are mentioned below:
Plant Cell: Animal Cell
:
Cell Shape Cell Shape
Square or rectangular in shape Irregular or round in shape
Cell Wall Cell Wall
Present Absent
Explanation:
I would say a but I think it would be dependent on location
Explanation:
What role do these parts play?
Cell walls: provide structural and mechanical support, protect cells against pathogens, maintain and determine cell shape, control the rate and direction of growth and generally provide form to the plant.
Cytoplasm: provides the platform for most chemical processes, controlled by enzymes.
Cell membrane: acts as a barrier, controlling the movement of substances into and out of the cell.
Chloroplasts: As described above, simply contain chlorophyll, a green substance which absorbs light energy for photosynthesis.
Vacuole: the container that holds moisture, and keeps the plant turgid.
Nucleus: this contains genetic make (the DNA), which controls the activities of the cell.
Chlorophyll absorbs the light energy needed to make photosynthesis happen. It is important to note that not all the color wavelengths of light are absorbed. Plants mostly absorb red and blue wavelengths — they do not absorb light from the green range
