[#151] Photosynthesis takes place faster in
Correct Answer

(C) red light

Explanation

Solution: Photosynthesis takes place faster in red light . Photosynthesis is the process by which green plants and some other organisms convert light energy into chemical energy. It primarily occurs in chloroplasts, where pigments such as chlorophyll absorb light. While chlorophyll absorbs light from various parts of the light spectrum, it is most efficient in the red and blue parts of the spectrum. Red light is absorbed more effectively than other colors, making it the most favorable for photosynthesis. So, the correct option is: Option C: red light Photosynthesis takes place faster in red light .

[#154] The photosynthesis occurs in the
Correct Answer

(A) Day

Explanation

Solution: The photosynthesis occurs in the day.

[#155] The oxygen released during photosynthesis process comes from
Correct Answer

(A) H 2 O

Explanation

Solution: During the process of photosynthesis, green plants and some other organisms use sunlight to convert carbon dioxide (CO 2 ) and water (H 2 O) into glucose (a type of sugar) and oxygen (O 2 ). This process takes place in the chloroplasts of plant cells and is represented by the following chemical equation: 6 CO 2 + 6 H 2 O + light energy → C 6 H 12 O 6 + 6 O 2 As you can see, the oxygen released during photosynthesis comes from the water molecule (H 2 O). Carbon dioxide (CO 2 ) is used to produce glucose (C 6 H 12 O 6 ), which serves as an energy source for the plant. So, the correct answer is Option A: H 2 O .
