Science 7 | C2 Photosynthesis and Respiration (2.1/2.2)

What are the products of photosynthesis?

Glucose and oxygen

The main thing that happens during the second stage of respiration is:

Glucose is broken down even smaller in the mitochondria and large amounts of energy are released

The main thing that happens during the first stage of respiration is:

Glucose is broken down into smaller molecules in the cytoplasm...small amount of energy is released

What happens during respiration?

Glucose is broken down, releasing energy.

Where in the cell does the second stage of cellular respiration take place?

Mitochondria

Which organelle in cells is responsible for most of the energy production?

Mitochondria

What gas is needed for our body to release the energy from the food we eat?

Oxygen

What are the raw materials of respiration?

Oxygen and glucose

What do the respiratory system and cellular respiration have in common?

Oxygen plays a key role in both

The chloroplast is the site of

Photosynthesis

Plants use sunlight to make food in a process called

Photosynthesis.

The main thing that happens during the second stage of photosynthesis is:

Sugar in the form of glucose is produced from hydrogen, water and carbon dioxide.

Write the formula for photosynthesis.

Sunlight + 6CO2 + 6H2O C6H12O6 + 6O2

Would you expect a plant to produce more oxygen on a sunny day or a cloudy day?

Sunny

Think about respiration when you answer this question. If you were to eat a saltine cracker and NOT swallow it, the cracker would eventually taste sweet. Why do you think this is?

The food molecules break down into glucose

What causes stomata to open and close

Water

What are the products of respiration?

Water, carbon dioxide, and energy

An organism that makes its own food is a(n)

Autotroph - producer .

Bromothymol blue is an indicator for

Carbon dioxide

What are the raw materials of photosynthesis?

Carbon dioxide, water, light energy

The main pigment found in the chloroplasts of plants is

Chlorophyll

Which organelle in the plant cell is responsible for collecting the sun's energy to use in photosynthesis?

Chloroplasts

Another word for a heterotroph is

Consumer .

Where in the cell does the first stage of respiration take place?

Cytoplasm .

How do we get the glucose we need to power our cells?

Eating

What does respiration produce a lot of

Energy

The main thing that happens during the first stage of photosynthesis is:

Energy from the sun is captured and water is split into hydrogen and oxygen.
