Photosynthesis #6

People take in and release gases from the air when they breathe. Which exhaled gas is a waste product of respiration?

• oxygen

• helium

• hydrogen

• carbon dioxide

The students in Mr. Andrew's class observed bubbles coming out of a stem. What are the bubbles being released by the plant?

• carbon dioxide

• helium

• hydrogen

• oxygen

In which part of the plant does photosynthesis MOST likely take place?

• bark

• roots

• trunk

• leaves

Animals and plants need oxygen to live. Oxygen is released in photosynthesis. Which cycle includes photosynthesis?

• carbon cycle

• water cycle

• rock cycle

• nitrogen cycle

A plant takes in carbon dioxide and water and converts it into sugar. This process requires an energy input because the sugar that is formed has more energy that the carbon dioxide and water from which it is made. Which explains how this is possible?

• Plants convert light energy from the Sun into the chemical energy necessary to make the sugars

• Plants absorb heat energy from the Sun and soil necessary to make the sugars

• Plants absorb chemicals through their roots for the energy necessary to make the sugars

• Plants convert mechanical energy into chemical energy to make the sugars
