Following are One Mark Questions and objective multiple choice question from Biology of 10th class for AP and Telangana students. These are for English medium students.
Q: Why is it necessary to destarch a plant before performing any experiment on photosynthesis?
A: If we do not destarch a plant before performing the experiment on photosynthesis, the starch present in the plant may interfere with the result of the experiment.

Q: What is emulsification?
A: Fats are digested by converting them into small globule like forms by the help of bile juice secreted from liver. This process is called emulsification.
Q: What is the function of epiglottis?
A: Epiglottis controls the movement of air and food towards their respective passages.
