​WHAT IS THE ENERGY ORGANISMS USE?

WHY DO WE NEED ENERGY?

​Glucose is the main source of energy for living things.

​

​Glucose is also known as "blood sugar."

​*sugars=carbohydrate.

​

​Organisms convert glucose to ATP(energy molecule)

​Anytime you see ATP, think, Energy molecule cells use

​WHAT IS THE ENERGY ORGANISMS USE?





GLUCOSE --> ATP

​WHERE DO ORGANISMS GET GLUCOSE??

​Some organisms can make
their own glucose (??????).





Others have to eat other organisms
to get glucose.

🚨Photosynthesis is the process plants use to make their own glucose.

​-uses carbon dioxide and water as reactants (ingredients) & solar energy (sunlight)

​Photosynthesis
-makes glucose and oxygen.

HOW can plants do photosynthesis?

​Plant cells can do photosynthesis because they have organelles called chloroplasts. Choroplasts use chlorophyll (pigment) that absorbs light energy.

Only green light is reflected, making plants green

Chloroplasts are found anywhere a plant is green but more concentrated in the leaves.

Multiple Choice

What type of food does a plant make for itself through photosynthesis?

• Pizza

• Glucose (a type of sugar)

• H2O (Water)

• Lactose (a type of sugar)

Multiple Choice

Glucose is the sugar plants make through photosynthesis.

Plants use glucose as their food.

Do human also use glucose?

• No. Glucose is only used by plants.

• Yes. In humans, glucose is known as "food sugar".

• Yes. In humans, glucose is known as "blood sugar".

• No. Humans convert glucose to another type of food.

Multiple Choice

What are the reactants (ingredients) of photosynthesis?

• CO2 + H2O

  (Carbon dioxide and water)

• C6H12O6 + O2

  (Glucose and oxygen)

• H20 + O2

  (Water and oxygen)

• CO2 + O2

  (Carbon dioxide and oxygen)

Multiple Choice

What are the products of photosynthesis?

• CO2 + H2O

  (Carbon dioxide and water)

• C6H12O6 + O2

  (Glucose and oxygen)

• H20 + O2

  (Water and oxygen)

• CO2 + O2

  (Carbon dioxide and oxygen)

Multiple Choice

In addition to carbon dioxide (CO2) and water (H2O), what else does a plant need to do photosynthesis?

• Oxygen (O2)

• Sunlight (solar energy)

• Glucose (C6H12O6)

• Soil

Multiple Choice

When you breathe, what are you breathing in?

What are you breathing out?

• You breathe in oxygen (O2).

  You breathe out carbon dioxide (CO2).

• You breathe in carbon dioxide (CO2).

  You breathe out oxygen (O2).

• You breathe in oxygen (O2).

  You breathe out carbon monoxide (CO).

Multiple Choice

When a plant does photosynthesis, what is it taking in from the air?

What is it releasing to the air?

• It takes in oxygen (O2).

  It releases carbon dioxide (CO2).

• It takes in oxygen (O2).

  It releases carbon monoxide (CO).

• It takes in carbon dioxide (CO2).

  It releases oxygen (O2).

Multiple Choice

Which one of these organelles makes food for the plant through photosynthesis?

• Vacuole

• Nucleus

• Cell Wall

• Chloroplast

​Once an organism has glucose, it must convert that glucose into energy (ATP).

The process of converting glucose to ATP is called "cellular respiration."

​

​

​

​

Uses: Glucose and oxygen
Makes: Carbon dioxide(CO2), water (H2O), & ATP

Cellular respiration releases CO2 (carbon dioxide) & H2O (water) as byproducts. This is why you breathe out carbon dioxide and water vapor.

HOW? Cells use an organelle called the MITOCHONDRIA for cellular respiration

Mitochondria inside a cell:

Both plants and animals do cellular respiration.

The only difference is how they get their glucose.

Plants get their glucose through photosynthesis. Animals get their glucose by eating food.​

​

​

​

Both plants and animals do cellular respiration. They both have mitochondria.
-But only plant cells have chloroplasts.

Mitochondria inside a cell:

Notice that photosynthesis and cellular respiration are opposites.

Photosynthesis takes carbon dioxide and water to make glucose and oxygen.

Cellular respiration takes glucose and oxygen to make carbon dioxide and water + ATP (________)​
