Which statement best distinguishes plant and animal as they relate to amino acids? a) plans can synthesize all twelve amino acids. humans must eat plans or animals to obtain some of these amino acids b) plans can synthesize all twelve amino acids. humans must eat plans to obtain all of these amino acids c) plans can only synthesize ten amino acids. humans synthesize the other ten amino acids d) plans and humans both synthesize all twelve amino acids. humans must supplement a few of these by eating plans.

Ans.

There are twenty amino acids that take part in protein synthesis. These amino acids act as precursor for all protein molecules and are known as essential amino acids. Plants can synthesize all twenty amino acids from simple precursors, while animals can make only twelve amino acids. Animals obtain remaining eight amino acids by eating plants.

Thus, the correct answer is 'option) D.'

The correct answer is the first option - Plants can synthesize all twenty amino acids. Humans must eat plants or animals to obtain twenty of these amino acids. We cannot just create these amino acids on our own the way plants can - we get them from the food we eat, which includes both animals and plants, not just one of them. This is the main difference between animals and plants when it comes to amino acids.

Amoebae move by growing an extension of their bodies in the direction of movement and then flowing into it. this extension is called a  pseudopod  because when it's fully extended it resembles a limb, despite being only an extension of the amoeba's plasma membrane.
