Step by step
Solved in 2 steps
- INSTRUCTION: PLEASE ANSWER THIS QUESTION IN YOUR OWN WORDS NOT LONGER THAN 250 WORDS. Apples are sweet-tasting fruits that attract and are eaten by fruit-eating animals, which are agents for seed dispersal. How could you explain the fact that the seeds of such an attractive fruit contain cyanide-producing chemicals?Acclimatization has been one of the major obstacles to the use of tissue culture in crop improvement. Explain why this process is necessary for the ex vivo survival of tissue culture derived plants.Part F - How to determine transpiration rates by the whole plant method Which of the following best explains why the plant in front of the fan lost more mass than the control plant in normal room conditions? The leaves of the plant in front of the fan had the highest initial water potential and therefore lost the most water. The control plant had lower initial water potential in the root area and therefore lost less water. The control plant had a lower initial mass and so lost water at a decreased rate. The fan rapidly moves water molecules away from the leaf surface, lowering the water potential.
