In photosynthesis, what is the energy source
sun light
The moon
glucose
heat
In photosynthesis, which of the following is a raw material
water
glucose
oxygen
light
why a green leaves green?
Because they contain chlorophyll
Because they contain chlorine
Because they contain bromine
Because they contain bromoplasts
In photosynthesis, what sugar is produced
Glucose
Fructose
Lactose
Galactose
In the leaf, what pigment traps light energy
chlorophyll
bromophyll
lithophyll
carbophyll
Plants can store glucose as
starch
cellulose
glycogen
sucrose
In plants glucose is used
for the cell wall
to store their food
for energy to grow and repair
to taste sweet for bees
When we talk to plants we are providing
oxygen
carbon dioxide
a soothing tone
warmth
Plants photosynthesise
to make them sweet for bees
to make their fruit sweet
to make their own food
because we made them that way
Which of the following conditions would produce crops earlier
carbon dioxide
Light shades
air conditioning
extra oxygen
Other than temperature which of the following are limiting factors in photosynthesis
carbon dioxide concentration & light intensity
Oxygen concentration & light intensity
carbon dioxide concentration & Glucose
Nitrogen concentration & light intensity
Glucose is used for
storage of food
energy for growth and repair
the cell wall
making the plant taste sweet
Plants store glucose as
starch
glycogen
cellulose
sucrose
which of the following is a fate of glucose
used to make cellulose for the cell wall
Used to make the cell membrane
Used to make DNA
Used for protein synthesis
Stage one of photosynthesis is called
photolysis
photosplit
carbon fixation
calvin cycle
stage two of photosynthesis is called
photolysis
water spliting
carbon fixation
photofixation
stage two of photosynthesis
is an enzymatic process
uses light as an energy source
used to spit water
makes sucrose
stage two of photosynthesis can be limited by
temperature & carbon dioxide concentration
temperature & glucose
carbon dioxide and oxygen concentration
carbon dioxide concentration and light intensity
where does photosynthesis occur
chloroplast
chlorophyll
chloroplasm
chlorodrian
what is the waste product of stage 1 of photosynthesis
oxygen
