The reason for the differences in evolution in plants and animals.

Introduction:

The plants and animals vary a great amount in their structure, function, and activity. On the basis of these differences, both these species evolved in a different manner. The basic difference between them is that plants are immobile or stationary, while the animals are highly mobile.

Expert Solution & Answer

Explanation of Solution

The plants are sessile organisms that do not move or change their location. The leaves, roots, and certain other parts like pollens and seeds are mobile. The leaves are positioned in an orientation so as to obtain maximum amount of sunlight. The plants being immobile also developed photosynthetic pathway to manufacture their own food. The roots move in search of water and nutrients in the soil. On the other hand, animals are mobile and they change their location in search of food, for mating or to avoid predation.

The plants’ cells are enclosed within a cell wall, which is absent in case of animals. The cell wall provides rigidity to the plant because they are immobile. The development in plant continues throughout their lifetime, while the animals grow up to a certain stage only. This happens because the plants, unlike the animals are exposed to nearly all the environmental factors that lead to their wear and tear continuously.

The mode of reproduction is also quite different in both the species. Animals mate with the help of gametes (sperm from the male and ovum from the female). On the other hand, plants employ pollen grains (male gametes) and ovules (female gametes) for fertilization. The male and female organisms require to be in close vicinity in animals for reproduction to take place. While, the pollens in the plants can transfer to the ovary through air, water, and insects.

Conclusion

Therefore, it can be concluded that the structure, habitat, and mode of reproduction made the plants and animals different as far as evolution is concerned.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
