Lesson 4.1 & 4.2 Energy & Photosynthesis

Front

What is hydrotropism?

Back

The movement of plants towards water.

Front

What is a HETEROTROPH?

Back

An organism that cannot produce its own food and must consume other organisms for energy, e.g., a bear.

Front

In photosynthesis, what type of energy is converted to chemical energy?

Back

Light energy from the sun.

Front

What are the main products of photosynthesis?

Back

Oxygen and glucose.

Front

What type of energy do plants use to create their food?

Back

Light energy.

Front

Define photosynthesis.

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, which is essential for photosynthesis.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is essential for the respiration of most living organisms.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs consume other organisms for energy.
