Photosynthesis badger task
Photosynthesis is the reaction that allows plants to make their
own food; the plant uses chloroplasts in the green leaves to absorb
and trap sunlight in. They then use this sunlight to react with the
water and nutrients /minerals its roots absorb from the soil and
carbon dioxide in the air around us. There are many factors that
affect photosynthesis including heat the hotter it gets the rate
increases but after 40 degrees the enzymes in the leaves die.
Another is carbon dioxide concentrations, the more carbon dioxide
the higher the rate of photosynthesis
Rate of photos ynthesi s
Concentration of carbon dioxide
The word equation for the process of photosynthesis is
Light Water+carbon dioxide glucose+oxegon Chlorophyll
6CO2 + 6H2O (+ light energy) reaction for photosynthesis
C6H12O6 + 6O, this is the overall chemical
Roots Roots act like straws absorbing water and minerals from
the soil. Tiny root hairs stick out of the root, helping in the
absorption. Roots help to anchor the plant in the soil so it does
not fall over. Roots also store extra food for future use. Roots do
not have chloroplasts at all; this would be a waste of space in the
plant because the roots are underground.
Stems Stems do many things. They support the plant. They act
like the plant's plumbing system, conducting water and nutrients
from the roots and food in the form of glucose from the leaves to
other plant parts.
Leaves Most plants' food is made in their leaves in chloroplasts
which contain the chlorophyll this is where the photosynthesis
takes place
Flowers Flowers are the reproductive bits of the plant. Flowers
contain pollen and tiny eggs called ovules. After the flower
pollinates and its seeds are scattered and there will be new plants
Xylem and phloem These are tubes running up and down the plant. The
xylem takes up water and other minerals while the phloem transports
the glucose around the plant this is vital to the plant and you can
see the tubes in a cross-section of a stem especially in plants
such as celery.
Respiration Respiration in plants is one of the most important
processes in the plant; its needed in plants to carry out the
chemical change in gases and provides metabolic energy Biomass
Biomass is the total amount of living matter in plants. In things
like agriculture exceeded biomass from as little photosynthesis is
the basis of productivity; the famers can try many different things
to get a ratio of biomass of up to 40:1! They have different ways
of trying to reach this level by 1. Plant the proper plants at the
proper time. 2. Space the plants properly (less competition).3.
To know the plants specific plant's water requirements very
carefully.
4. To know the plant's nutrient requirements very carefully. 5.
Be known about the plant's rooting patterns.
6. Reduce weed competition. Various things can slow down biomass
oxygen production
Things which affect biomass production and oxygen evolution:
algal beds - pollution reefs - pollution tropical rainforests -
logging & clearing swamps - draining marshes - draining
