Photosynthesis, Respiration, and Transpiration Guided Notes
Photosynthesis is the process by which plants make food.
Photosynthesis vs. Respiration
Photosynthesis
Respiration
“photo” =_____________ and “synthesis” =_____________________
This happens to every plant, and to some _____________ and _________ too.
Without photosynthesis, __________ wouldn’t exist (live).
What do plants need for photosynthesis to occur?

Carbon Dioxide (CO2)---

Water (H2O)---

Light--Transpiration is the flow of water through a plant.
Process of Photosynthesis
Transpiration is essentially just evaporation of water from plant _________.
1. Water is absorbed by the __________of green plants and is carried to the
leaves by the ________.
Studies have revealed that _________ of the moisture found in the atmosphere
(air) is released by plants through ______________.
2. Carbon dioxide is obtained (gathered) from the air that enters the _________
through the __________.
An acre of _________ gives off about ____________ gallons of water each day,
and a large _____________ can transpire ____________ gallons per year.
3. Plants capture sunlight using a compound called ______________. Chlorophyll
is ________, which is why so many plants appear green.
Process of Transpiration
4. The plant makes __________ (sugar) and oxygen.
---Glucose (sugar) helps the plant ________.
---Oxygen goes up into the ______ to help animals and humans _________.
Respiration is a process in which plants, animals, and humans take in _________
and release carbon dioxide.
Plants---Take in oxygen through the _________ and use it to get _________ they
need to burn food.
Humans and animals---Take in oxygen to help them burn digested ________ and
get _________.
1. Plants absorb water from the ________.
2. The water moves through the _________ to the stems through the
__________ vessels to the ___________.
3. Once the water reaches the _________, some of it evaporates from the leaves
through the _______. This adds water vapor (gas) into the air.
