WHAT DO ALL OF THESE PLANTS HAVE IN COMMON?

Energy for Life When you see statements in red, you should write it down in your spiral. All living things require energy to grow and reproduce.

glucose Most living things on Earth break down glucose to get their energy.

vocabulary Minimize your power point and take a minute to google the following word: autotroph

autotroph When we come to a vocabulary word. Write the word in a different color. Then write the definition in your spiral vocabulary word! autotroph - (plants) use a process called photosynthesis to make glucose

vocabulary heterotroph Minimize your power point and take a minute to google the following word: heterotroph

heterotroph When we come to a vocabulary word. Write the word in a different color. heterotroph (non-plant) eat and then digest food to produce glucose. vocabulary word!

This is what your notes should look like so far:

vocabulary photosynthesis Minimize your power point and take a minute to google the following word: photosynthesis

photosynthesis vocabulary word! photosynthsis - The process by which any organism with chlorophyll uses radiant energy, carbon dioxide and water to make glucose and oxygen. Glucose is stored in leaves, stems and roots Oxygen is given off as a waste

Photosynthesis Equation Diagram this chemical equation on your paper: 6CO2 + 6H2O C6H12O6 + 6O2 carbon dioxide water glucose oxygen Sunlight Chlorophyll Reactants Products

Reactants 6CO2 + 6H2O C6H12O6 + 6O2 Reactants Products So, where does the plant get the reactants for photosynthesis: 6CO2 + 6H2O C6H12O6 + 6O2 carbon dioxide water glucose oxygen Sunlight Chlorophyll Reactants Products

carbon dioxide and water Sunlight can enter through the leaf’s surface. For water and carbon dioxide to enter, and oxygen to exit, leaves need a “doorway”.

carbon dioxide and water vocabulary word! stomata Openings in the underside of the leaf that act as doorways for raw materials and waste to enter and exit the leaf. Usually open during the day and closed at night

Stomata under a microscope.

Where does the reaction happen Where does the reaction happen? Diagram the plant cell and label the chloroplasts Chloroplasts Photosynthesis takes place inside a small green organelle called a chloroplast.

Products What happens to the products made during photosynthesis?: 6CO2 + 6H2O C6H12O6 + 6O2 carbon dioxide water glucose oxygen Sunlight Chlorophyll Reactants Products

glucose and oxygen The plant stores the glucose in roots, stems or leaves until needed. Luckily for us, the oxygen is given off through the stomata.

glucose What does the plant do when it needs energy? When the plant needs energy, the glucose is sent to the mitochondria in the cell.

vocabulary cellular respiration Minimize your power point and take a minute to google the following word: cellular respiration

glucose What does the plant do when it needs energy? vocabulary word! cellular respiration - glucose is broken apart to release energy inside the mitochondria of the cell. On your cell diagram, label the mitochondria. mitochondria

Animal cells, like ours, also have mitochondria that break glucose apart to release energy. The only difference is that plants can make glucose and animals have to eat food so their digestive system can get glucose from their food.

Write these two conversions down Energy Conversion Through photosynthesis plants and some other organisms convert: radiant energy chemical energy (from the sun) (stored as glucose) and energy (light) matter (leaves, stem, bark) Write these two conversions down

Pigments Chemical compounds that give things color

What makes a plant green? chlorophyll - green pigment found in plants that is necessary for photosynthesis. Plants can produce more chlorophyll when they get more sunlight. Photosynthesis only occurs in plant cells that have chloroplasts. vocabulary word!

All plants with green areas can produce food through photosynthesis. Do you think anything else can use photosynthesis? photosynthetic bacteria photosynthetic plankton algae

Energy for Life Plants provide food for the entire planet. They provide 90% of Earth’s oxygen. The filter out carbon dioxide which is a greenhouse gas. Why is it important to save trees?
