Oxygen
A pigment in chloroplasts that capture light energy
Chlorophyll
how old is photosynthesis
3.3 to 3.5 billion years old
what is the first step in the process photosynthesis
light energy is absorbed in to to leaves of the plant
what do plants need to make food?
water , energy , and , dioxide
Organelle in which photosynthesis takes place
Chloroplast
initial phase where light energy is converted into chemical energy
light reaction
what speeds up photosynthesis
carbon dioxide concentration
what is the second step of photosynthesis
the calvin cycle
what are is a reactants of plants
water, carbon dioxide
Fluid portion of the chloroplast
Stroma
light-absorbing molecules used by plants to gather the suns energy
pigment
what triggers photosynthesis
carbon dioxide, water, sunlight
how is sugar produced during the photosynthesis process?
plants convert carbon dioxide and water into glucose (type of sugar) using sunlight as energy.
what is a products of plants
oxygen ,glucose
A gas that plants take in from the atmosphere for photosynthesis
Carbon dioxide
organisms that make their own food
autotroph
what controls photosynthesis
enzymes closed by enzymes
what is water splitting?
water split into oxygen
where does photosynthesis occur
choloroplast
A type of sugar that plants produce as food during photosynthesis
Glucose
organisms that obtain food by consuming other living things
heterotroph
how long does photosynthesis take
2 hours
what is Light Absorption?
Chlorophyll, a pigment within the thylakoids, absorbs the light energy, which excites electrons
how is glucose created
glucose is created from the co2 and high energy molecules in the chloroplasts of plant cells
