Photosynthesis & Cellular Respiration

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants, algae, and some bacteria convert radiant energy (usually from sunlight) into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main ingredients needed for photosynthesis?

Back

The main ingredients needed for photosynthesis are sunlight, carbon dioxide, water, nutrients, and chlorophyll.

Front

Why is photosynthesis important for life on Earth?

Back

Photosynthesis is important because it produces oxygen for animals to breathe, creates energy for heterotrophs to use, and provides food for plants.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs sunlight, which is essential for the process of photosynthesis.

Front

What is thigmotropism?

Back

Thigmotropism is a plant's growth response to touch or physical contact, allowing it to grow around objects.

Front

What is gravitropism?

Back

Gravitropism is a plant's growth response to gravity, where roots grow downward and stems grow upward.

Front

What is phototropism?

Back

Phototropism is the growth of a plant in response to light, where plants grow towards the light source.

Front

What is hydrotropism?

Back

Hydrotropism is a plant's growth response to moisture or water, where roots grow towards areas with higher moisture.

Front

What is the chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
