​Diffusion

​The movement of particles from an area of high concentration to an area of low concentration until an equilibrium is reached.

Multiple Choice

What is a synonym for equilibirum?

• balance

• unequal

• high concentration

• low concentration

​Osmosis

​This is the diffusion of water specifically. Osmosis takes place through a

semi-permeable

membrane.

Multiple Choice

What does semi-permeable mean?

• some things can pass through

• nothing can pass through

• everything can pass through

Multiple Choice

Osmosis is specifically the diffusion of

• water

• salt

• oxygen

• carbon dioxide

​Transpiration

​Transpiration relies on ahdesion and cohesion.

Multiple Choice

Cohesion is...

• when molecules are attracted to other molecules of the same type

• when molecules are attracted to a different type of molecule

Multiple Choice

What does adhesion mean?

• A substance or molecule that is needed for a reaction to take place.

• An attraction between molecules of different substances.

• The evaporation of water from the leaves of a plant, drawing up water through the rest of the plant.

• A substance produced in a reaction.

Photosynthesis

​Plants are producers.

Producers make their own food. 

Plants make food through a process called photosynthesis. 

In photosynthesis, plants use energy from the sun to make sugar (specifically glucose).

Glucose is food for a plant.

Multiple Select

Which of the following are the products of photosynthesis? Choose all correct answers.

• oxygen

• H₂O

• CO₂

• glucose

• energy

Multiple Select

Which of the following are the reacta of photosynthesis? Choose all correct answers.

• oxygen

• H₂O

• CO₂

• glucose

• energy

​Gas Exchange

​Cellular Respiration is the process where plants use oxygen and glucose to produce carbon dioxide and energy.

Multiple Choice

What is the opposite process to cellular respiration?

• transpiration

• photosynthesis

• osmosis

• diffusion

Multiple Choice

Why do plants produce less O₂ during the night?

• Humans breathe less at night.

• There is less light energy available.

• The plants are tired too.

• They are overwhelmed by CO₂.
