Проект. Сделайте заметки под заголовками упр.3. Используйте их, чтобы объяснить, как работает фотосинтез.

FOOD FROM THE SUN: animals eat plants to get energy, other animals eat these animals, plants produce their own food from the sun
WHAT IS PHOTOSYNTHESIS?: plants absorb carbon dioxide through their leaves, water through their roots. Chlorophyll in leaves absorbs energy from the sun.
THE LIGHT AND DARK REACTIONS: first stage is called light reaction where light is converted to chemical energy. Second stage is dark reaction where the plant converts carbon dioxide and water to carbohydrates.
NOW FOR THE SCIENCE BIT:
CO2+2H2O (sunlignt+green plants) -> CH2O + H2O
A LIFE-GIVING PROCESS: the plant produces food and also provides oxygen for life.
Plants produce their own food from the sun through a process called photosynthesis.
Photosynthesis uses carbon dioxide, water, chlorophyll and sunlight to produce carbohydrates which the plant uses as food.
There are two stages in photosynthesis. The first stage is called the light reaction and involves converting light energy to chemical energy and the second stage is called the dark reaction and consists in converting the carbon dioxide and water to carbohydrates.
