In a plant cell, photosynthesis and cellular respiration can both take place simultaneously. Plants carry out both photosynthesis and cellular respiration during the day. Cellular respiration continues because it provides the energy required for essential cell functions.

What role of  photosynthesis and respiration in plant?</h3>
Water and carbon dioxide are changed into oxygen and glucose during photosynthesis. The plant consumes glucose and produces oxygen as a byproduct.
Oxygen and glucose are transformed into water and carbon dioxide during cellular respiration. By-products of the process include carbon dioxide, water, and ATP, which is turned into energy.
To power cellular respiration, photosynthesis uses the energy it produces. During photosynthesis, solar energy is used, collected, and stored in the bonds of glucose molecules.
Therefore, photosynthesis and respiration not involve energy formation cycle.

The correct answer is absence of jaws.
Lampreys and hagfish are in the class Agnatha, they are jaw-less fish. The members of the agantha class are probably the earliest vertebrates. Scientists have found fossils of agnathan species from the late Cambrian period that occurred 500 million years ago.
