chloroplast

what are the organelles in which photosynthesis occurs

chloroplast

What does the word photo mean?

light

what the equation for photosynthesis?

ATP, NADPH

Since plants make their own food they are

Autotrophs

Why would a plant close its stomata?

Because it's hot and they don't want to lose water

What is the chemical equation for glucose

C6 H12 O6

What do CAM plants do to help reduce the loss of water and still capture carbon dioxide?

CAM plants close the stomata during the day and open them at night

Both of these evolutionary solutions are adaptations that change the way the plant stores what reactant for photosynthesis?

CO2 Carbon Dioxide

Which gas is removed from the atmosphere during photosynthesis?

Carbon Dioxide

gas that is a reactant of photosynthesis

Carbon dioxide

Which substances must a green plant obtain from its environment in order to convert light energy into chemical energy?

Carbon dioxide and water

A flask is placed outside in direct sunlight, during the day and at night to compare the amounts of carbon dioxide (CO2) and oxygen (O2). What will his analysis most likely show?

During the day, the amount of oxygen in the flask increases while the amount of carbon dioxide decreases.

Identify the chemical/process in E

H2O

The oxygen (O2) that is released form plants comes from?

H2O water

What does photosynthesis do for you?

It gives you oxygen to breathe It gives you food to eat

Autotrophs, such as plants, use light to make their own food. What happens to the light absorbed by a plant during photosynthesis?

It is converted to chemical energy which the plant stores as glucose

What is the chemical/process in B

Light Energy

Photosynthesis consists of two processes. What are they.

Light reactions, Calvin Cycle (dark reactions)

Light reactions can only happen way? What about the Calvin Cycle?

Light reactions: only during the day Calvin Cycle: any time of the day

Another name for the light independent reaction is called a The Kelvin cycle b The Calvin cycle c The Water cycle d The Carbon cycle

The Calvin Cycle/ The Dark Cycle

Transpiration is

The evaporation of water out of stomata plants

What would be a best explanation for the gas accumulated in one of the inverted test tubes?

Pigments found in plants are necessary for a transferring NADPH into NADP b cell growth c converting ATP into ADP d capturing energy from sunlight

d capturing energy from sunlight

chemical reactions are not important to all living things true/false

false; they are important to all living things

All of the functions of the Calvin Cycle:

forms sugar from carbon dioxide, using ATP for energy, and NADPH for reducing power

Plant cells have mitochondria, which use glucose to produce ATP. Where does the glucose originate

from photosynthesis, which occurs in chloroplasts

Plant cells have mitochondria, which use glucose to produce ATP. Where does the glucose originate?

from photosynthesis, which occurs in chloroplasts.
