Open Ended

Why are Cacti survive better in the hotter and drier environments like the desert compared to normal plants?

Multiple Choice

What is an Autotroph?

• An organism that eats meat.

• An organism that needs to consume other organisms for food.

• An organism that makes its own food from sunlight.

• An organism that eats plants.

Multiple Select

Select 2 of the follow answers that are produced by Photosynthesis.

• Water

• Carbon Dioxide

• Oxygen

• Sunlight (Light Energy)

• Glucose (Sugar/food)

Multiple Choice

Which organelle is responsible making food (Glucose) using sunlight?

• Cell Membrane

• Nucleus

• Chloroplast

• Mitochondria

Multiple Choice

What part of the leaf allows carbon dioxide to enter the plant and oxygen to leave it?

• Chlorophyll

• Phloem

• Xylem

• Stomata

Multiple Choice

How does most of the water needed by the plant get into its leaves?

• It enters through the stomata

• The roots absorb it and then it travels up the phloem

• It's made during a chemical reaction in the leaf

• The flowers capture water and deliver it to the leaves

Multiple Choice

During the light reaction, water (H20) is converted into

• Oxygen (O2)

• Carbon Dioxide (C02)

• Sunlight energy

• Sugar (C6H12O6)
