Photosynthesis and the sun

We have to "steal" energy from plants!

whether we eat meats, vegetables, fruits, fish, we are stealing food from organisms containing chloroplasts!

the sun powers all of the food webs for life

Multiple Select

Autotrophs are organisms which ( 3 answers)

• Depend on Heterotrophs for food

• Convert sunlight into food

• Need sunlight, CO2 and water to produce energy (sugar)

• Are the largest food source on the planet.

Multiple Choice

A Heterotroph is an organims which

• Can makes its own energy from the sun.

• Can not make its own energy

• Can be recharged in the sun

• Must be in the water.

Multiple Select

The following are examples of Autotrophs: (2 answers)

• Really cute bunny

• Apple Tree

• Onion plant

• Eukaryotes

Multiple Choice

What is the source of all energy on earth to create the weather and help create energy for us?

• Herbivores

• Moon tides

• electricity from lighting

• Sunlight

Photosynthesis needs sunlight.

the sunlight is absorbed by the leaf into the chloroplast/chlorophyll. Light + CO2 + water gives us Sugar and O2

The sugar making recipe:( Reactants): sunlight, CO2 and water.

The products: O2 and Sugar

Multiple Select

Photosynthesis is the process that uses these products to create sugar

• Where plants take in water

• Plants take in CO2

• Plants take in Sunlight

• Creating Sunlight

Multiple Select

What are the 3 reactants needed to create sugar in photosynthesis?

• Water

• Oxygen O2

• Carbon Dioxide CO2

• Sunlight

Open Ended

Why does life on Earth depend on plants? Be specific and give examples.

Multiple Choice

The processs of Cellular Respiration uses oxygen to convert sugar into this quick energy source called :

• Mitochondria

• Protein

• ATP

• Carbon Dioxide

Multiple Select

For a plant to make sugar through photosynthesis besides sunlight it also needs these two other reactants:

• Oxygen O2

• Carbon Dioxide CO2

• Dirt

• Water

Multiple Select

In photosynthesis the reactants of Sunlight, CO2 and water create these two products which are essential to life:

• Meat

• Plants

• Oxygen

• Sugar

Multiple Choice

Cellular respiration takes place in this organelle which hold the ATP for the cell and is the powersouce.

• Ctyoplasma

• Goldgi body

• Nucleus

• Mitochondria

Multiple Choice

This organ takes the sunlight and combines it with Carbon Dioxide and water to produce sugar.

• ATP

• Nucleus

• Chloroplast

• Mitochondria

Respiration happens when

• Oxygen in used to

• burn sugar. That is why we need to breath!

• Without the oxygen of plants, we could not burn our energy (sugar).

Multiple Select

As humans we are considered ( 2 answers)

• Autotrophs and producers

• Eukaryotes

• Hetrotrophs and consumers

• Prokaryotes

Multiple Choice

Autotrophs use sunlight to create the process of ______ to obtain their energy source.

• Mitochondria

• Respiration

Multiple Choice

Respiration uses Oxygen take in by the plant leaves to burn/breakdown this energy product:

• Sugar

• Protein

• Enzyme

• Mitochondria

Multiple Select
