Which of the following statements regarding photoperiodism is false?
1 The response of plants to periods of light/day is termed photoperiodism
2 The shoot apices cannot perceive photoperiods
3 In day neutral plants there is no corelation between exposure to light duration and induction of flowering response
4 Shoot apices modify themselves into flowering apices prior to flowering
5 The site of perception of the light/dark duration is the flower
Explanation:
: Photoperiodism is a process that plant use to determine when to flower, there are some statements regarding photoperiodism. (a) The response of plants to periods of light/day is termed photoperiodism. (b) The shoot apices cannot perceive photoperiods (c) In day neutral plants there is no corelation between exposure to light duration and induction of flowering response (d) Shoot apices modify themselves into flowering apices prior to flowering Hence, it is clear from above explanation that option (e) is false regarding to the question.

Plants flower in response to a certain ratio of light to dark in a day, which reflects seasonal changes. This response is known as:
1 verbalization
2 photoperiodism
3 photorespiration
4 photosynthesis
Explanation:
B Plants flower in response to a certain ratio of light to dark in a day, which reflects seasonal changes. This response is known as photoperiodism. It is the physiological reaction of organism to the length of night or a dark period. It happens in plants and animals. They are classified under their group. According to the photoperiods- (i) Short day plants (ii) Long day plants (iii) Day neutral plants

What is true for photolithotrops : -
1 Obtain energy from radiations and hydrogen from organic compounds
2 Obtain energy from radiations and hydrogen from inorganic compounds
3 Obtain energy from organic compounds
4 Obtain energy from inorganic compounds
Explanation:
B Photolithotrops are those plants that obtain energy from radiation and hydrogen from inorganic compounds. In other words, photolithotrops manufacture their own organic nutrients from inorganic material.
