Warm Up 1.What are the 3 types of passive transport? 2.Active transport flows from areas of ________ concentration to ________ concentration. 3.What is the cell wall made of? 4.How is blood glucose maintained in a cell? 5.Explain the difference between diffusion and facilitated diffusion. 6.What occurs at vacuoles?

Warm Up 1.Write the equation for aerobic cellular respiration. 2.What are the reactants of aerobic cellular respiration? 3.What are the products of aerobic cellular respiration? 4.What is the main goal of aerobic cellular respiration? 5.What are the waste products of aerobic cellular respiration?

Photosynthesis

THE BIG PICTURE- PHOTOSYNTHESIS! In the presence of light, plants transform CO 2 and water into carbohydrates and release oxygen. WRITE BOTH EQUATIONS!!! CARBON + WATER + ENERGY  SUGARS + OXYGEN DIOXIDE(Sunlight) 6 CO 2 _____________ + ____________ + __________  _______________ + ____________ 6 H 2 OC 6 H 12 O 6 6 O 2

THE BIG PICTURE PHOTOSYNTHESIS provides the _____________ we breathe and the __________ we need to survive OXYGEN sugars CARBON + WATER + ENERGY  SUGARS + OXYGEN DIOXIDE

PHOTOSYNTHESIS HAPPENS IN CHLOROPLASTS

Factors that affect photosynthesis A.Amount of water or carbon dioxide B.Temperature and pH C.Light intensity

Factors that Affect Photosynthesis ____________________ Water and carbon dioxide are one of the raw materials needed, so a shortage can ____________ photosynthesis AMOUNT OF H 2 O or CO 2 slow or stop

Factors that Affect Photosynthesis Photosynthesis enzymes function best between 0° C - 35° C and at neutral pH levels (~6-8 pH) At levels above or below this range, photosynthesis will slow or stop TEMPERATURE and pH

Factors that Affect Photosynthesis ____________________ More light increases rate of photosynthesis up to a certain level until plant reaches its maximum rate of photosynthesis LIGHT INTENSITY

How do plants take in CO 2 and release O 2 ? Through specialized cells on the underside of the leaf. It is called stomata including 2 guard cells. They tend to close during the day and open during the night… why? Less gas is lost during the night.

Warm Up Animal OR Plant OR Both 1.Contains cells with chloroplasts 2.Contains cell with mitochondria 3.Gets energy through eating food 4.Makes own food through photosynthesis 5.Completes cellular respiration

Warm Up 1.Why would a leaf have a large number of stomata? 2.What gas moves into the stomata? What gas is released from the stomata? 3.Why would most stomata be located on the underside of a leaf (lower epidermis) rather than the top of a leaf (upper epidermis)? 4.When is a stomata more likely to be closed? Why?
