Photosynthesis & Respiration

Photosynthesis & RespirationEnergy for Plants & AnimalsEssential Standards6.L.1 Understand the structures, processes and behaviors of plants that enable them to survive and reproduce.Clarifying Objectives6.L.1.2 Explain the significance of the processes of photosynthesis, respiration, and transpiration to the survival of green plants and other organisms.

Essential QuestionHow do Photosynthesis, Respiration & Transpiration relate when discussing plants & other organisms?

What is the process of photosynthesis?

What is the process of respiration?

What is the process of transpiration?Animals vs. PlantsAnimals cannot make their own food and survive on their own

Animals either have to eat plants or other animals to survive

Plants CAN make their own food

This is why PLANTS are the beginning of the FOOD CHAIN

Suns EnergyAll energy comes from the sun either directly or indirectly

Energy comes from the sun directly to plants as they use the sunlight in photosynthesis

Energy comes from the sun indirectly to animals through eating plants (that got their energy from the sun) or other animals

PhotosynthesisPlants food making process

Photosynthesis is a chemical reaction where ENERGY from light (sun) is changed to CHEMICAL ENERGY which plants can use

The converted chemical energy is turned into sugar which is called glucose

Light, Water, Carbon DioxideAll plants need three things to growLight (sun)Water (rain)Carbon Dioxide (Atmosphere)

Chloroplasts & ChlorophyllPhotosynthesis takes place in a tiny piece of the plant called the Chloroplast

Chloroplasts have Chlorophyll in them

This is what gives the leaves of the plants their green color

Chloroplasts are located in the leaves of the plants

SunlightSun shines down onto a plant

The sunlight shines onto the leaves of the plant which is where the Chloroplasts are

The Chlorophyll in the leaves trap the sunlight to make sugar

Carbon Dioxide & WaterNext the plant takes in Carbon Dioxide through the Stomata in the leaves

Next the Water is taken from the ground through the plants root system

Water + Carbon Dioxide + Sunlight The water from the roots combine with the Carbon from the atmosphere and the sunlight from the sun to make GLUCOSE (sugar energy)

The plant then stores the glucose in the stem & flower of the plants

Plant Waste = OxygenWhen these three combine they dont use everything and some of it is turned to waste and given off back into the atmosphere. This waste is called Oxygen

What is the process of photosynthesis?

RespirationRespiration is another chemical reaction that works with photosynthesis

It is the opposite of photosynthesis

It released energy to organisms and its waste is Carbon Dioxide

Animals Eat & Breathe Animals eat a plant or another animal and get glucose from that plant or animal they ate

Animals breathe in the oxygen that the plant gave out as waste

Mitochondria goes to WorkThe glucose (sugar) (carbs) and the oxygen travel to the Mitochondria which is part of each animal cell

Mitochondria breaks down the oxygen & glucose (carbs) and releases water vapor & carbon Dioxide into the air

At the same time it releases energy into the cell

What is the process of Respiration?

TranspirationTranspiration is when plant leaves open their cells to take in carbon dioxide and lose water to evaporationStomata & guard cells openWater EvaporatesCarbon Dioxide enters the plant

Transpiration is important because it moves the water throughout the plant

Opening the StomataPlant opens the Stomata of the leaf to let water vapor out & Carbon Dioxide in

The plant immediately wants to replace the water it lost through the stomata

Transpiration makes the roots suck more water from the ground

Moving through the PlantTranspiration bonds the water molecules together & the Xylem sucks the water up through the stem & all the way to the flower (working against gravity)

Essential QuestionGet with a partner and answer

What is the process of Transpiration?

How do they RelatePhotosynthesis & Respiration use each other to continue their process

In order to complete Photosynthesis the plant must have Carbon Dioxide which they can only get from animal respiration

In order to complete Respiration the animal must have Oxygen which it gets from the plant when the plant goes through photosynthesis

In order for Transpiration to occur the plant must take in carbon dioxide from respiration

Essential QuestionGet with a partner and answer

How do Photosynthesis, Respiration & Transpiration relate when discussing plants & other organisms?EOG QuestionsLeaves perform many tasks and are important to the survival of plants.

How is transpiration controlled in the leaves of a plant?

Explain why transpiration is important to the survival of the plant.Important PointsPlants are the beginning of the FOOD CHAIN

Photosynthesis & Respiration work together & relate to each other

Photosynthesis combines Carbon+Water+Sunlight to give the plant energyRespiration breaks down glucose + Oxygen and releases energy in the process

Photosynthesis takes place in the Chloroplasts which is inside the plant cells

Respiration takes place in the Mitochondria which is inside the animal cells
