❓ Mystery Bag
If you increase the amount of light a plant receives, what typically happens to the rate of photosynthesis?
It increases
This is the specific organelle in a plant cell where photosynthesis happens.
Chloroplast
These are the three main "ingredients" (reactants) a plant needs to perform photosynthesis.
Water, Carbon Dioxide, and Sunlight
In an ecosystem, these organisms are responsible for "fixing" carbon from the atmosphere into a solid form.
Producers/Plants
This is the original source of almost all energy in most ecosystems on Earth.
The sun
Why do leaves appear green to our eyes?
Chlorophyll reflects green light and absorbs other colors
These are the tiny pores on the underside of leaves that allow gases like CO2 and O2 to enter and exit.
Stomata
This is the primary sugar produced by plants that serves as food for the plant and eventually for animals.
When an animal eats a plant, the carbon atoms move from the plant to the animal. This process is called ________.
Consumption/Ingestion
This green pigment in plants is responsible for absorbing light energy.
Chlorophyll
Does a plant perform cellular respiration?
YES! they need to break down the sugar they make to grow
This part of the plant is responsible for pulling water from the ground to be used in photosynthesis.
The Roots
Photosynthesis converts light energy into this type of energy, which is stored in the bonds of sugar molecules.
Chemical Energy
This process, performed by both plants and animals, releases carbon dioxide back into the atmosphere after breaking down food.
Cellular Respiration
If a plant is kept in total darkness, it cannot produce this specific molecule, causing it to eventually die.
Glucose/Sugar
In the Flanders test tubes experiment, why can a plant and a snail survive longer together than they can alone?
The plant provides oxygen/food for the snail; the snail provides CO2 for the plant.
The chemical equation for photosynthesis can be written as: 6CO2 + 6H2O + light -->
Finish the equation.
C6H12O6 + 6O2
This gas is released as a byproduct (waste) of photosynthesis, which most living things need to breathe.
Oxygen
These organisms break down dead matter, returning carbon to the soil and atmosphere.
Decomposers
Unlike matter, which cycles round and round, energy does this through an ecosystem.
Flows in one direction/is lost as heat
This law states that matter (like carbon atoms) cannot be created or destroyed, only rearranged.
Law of Conservation of Mass/Matter
This is the name of the "tubes" or tissue in plants that transport water from the roots to the leaves.
True or False: Plants get their "mass" (the stuff they are made of) primarily from the soil and water
False: most of a plant's mass comes from the Carbon Dioxide in the air
This is the chemical formula for the Carbon Dioxide molecule.
Explain how a carbon atom in the air today could end up as part of a muscle cell in a lion.
CO2 is taken in by grass -> Grass makes glucose -> Zebra eats grass -> Lion eats zebra
