Chloroplasts - found only in plants and algae. they convert solar radiation energy to chemical energy usable for the cell's metabolism.
mitochondria - found in both plants and animals, they produce energy (in the form of ATP - chemical compound) by decomposing sugars and fats. they use up oxygen to do it.

I Really hope this was helpful to you i tried my best to answer all the questions
Explanation:
<h3>{Differences in Physical Characteristics}</h3>
Vertebrates have a skeletal structure with a spinal column or backbone.Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull.
Explanation:
<h3>{Invertebrates}</h3>
•Invertebrates do not possess a backbone not an internal skeleton.
•Invertebrates have an exoskeleton.
•Body size varies but most are generally smaller than vertebrates. However, some invertebrates grow to gigantic proportions – such as the colossal squid (46 feet in length).
<h3>{Vertebrates}</h3>
•Vertebrates possess a backbone and an internal skeleton.
•Vertebrates do not possess an exoskeleton.
•Generally, vertebrates are comparatively larger than invertebrates
Because the sun's light is not good enough for it
The structure of the plasma membrane makes this type of transport necessary for fluids is discussed below:
<h3>What do you mean by phospholipid membrane?</h3>
The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells. A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells.
Because water and other polar or charged substances cannot easily traverse the hydrophobic core of the membrane, the phospholipid bilayer created by these interactions serves as an effective barrier between the interior and exterior of the cell.
The complete sentence of question is:
