Do plants grow faster under light or in darkness?

Solution

To determine whether plants grow faster under light or in darkness, we need to set up an experiment

Formulate a hypothesis: "Plants will grow faster under light than in darkness."

Plan the experiment: - Materials: Two identical plants, light source, dark room, water, ruler. - Method: Place one plant under a light source and the other in a dark room. Water both plants equally and measure their growth over a set period (e.g., one week)

Conduct the experiment: - Observe and record the growth of both plants daily

Conclude the experiment: - Compare the growth measurements of both plants to determine which one grew faster

Answer

Plants grow faster under light than in darkness.

Key Concept

Photosynthesis: Plants require light to perform photosynthesis, a process that converts light energy into chemical energy, which is essential for their growth. Equation:

6CO_2 + 6H_2O + light \ energy \rightarrow C_6H_{12}O_6 + 6O_2

(Carbon dioxide + water + light energy produces glucose and oxygen)

Explanation

Light is a critical factor for photosynthesis, which is necessary for plant growth. Without light, plants cannot produce the energy they need to grow efficiently.
