Photosynthesis, Carbon Cycle, and Properties of Materials

Front

What is photosynthesis?

Back

The way that plants make glucose and oxygen from carbon dioxide and water, using energy from light.

Front

What is the word equation for photosynthesis?

Back

Carbon dioxide + Water + Light energy → Glucose + Oxygen.

Front

Why is photosynthesis important?

Back

It produces oxygen for organisms that aerobically respire and perpetuates the food web by producing food and energy.

Front

What is chlorophyll?

Back

A green pigment found inside chloroplasts in plant cells, capturing light energy.

Front

What is the effect of light intensity on photosynthesis?

Back

Light intensity is directly proportional to the rate of photosynthesis.

Front

What are stomata?

Back

Small holes in the epidermis of a leaf, which allow gases to diffuse into and out of the leaf.

Front

What is fertilizer?

Back

A substance containing minerals, which is added to soil to help plants grow well.

Front

What are two essential minerals found in fertilizers?

Back

Magnesium (for producing chlorophyll) and Nitrates (for constructing proteins).

Front

What happens to plants without magnesium?

Back

They cannot photosynthesize.

Front

What is the carbon cycle?

Back

The process by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere.
