From these observations, students conclude that photosynthesis takes place in
Elodea
. Through experimentation, students conclude that light is necessary for photosynthesis. Observe chloroplasts and identify both the stem and the leaves of an Elodea plant as areas where photosynthesis occurs.
Does Elodea have photosynthesis?
Like E. densa, its leaves are only 2 cells thick, making the microscopic observation of plant cell structure, chloroplasts, and cytoplasmic streaming simple. You
can successfully perform all other common photosynthesis activities
using this species of Elodea.
Where does photosynthesis take place in the Elodea plant?
Lesson Description: Elodea is a common fresh water plant. Cells in the leaves and stem contain
chloroplasts
(the site of photosynthesis). Chloroplasts contain chlorophyll which is the molecule that absorbs sunlight. Photosynthesis uses Carbon Dioxide and water which generates glucose and oxygen.
Can Elodea perform photosynthesis in dark?
The Elodea in the dark
lacked light for photosynthesis
, so CO2 levels should have increased and O2 levels decreased as respiration occurred.
How do Elodea plants photosynthesis?
During photosynthesis, the plant
absorbs carbon dioxide from the water and releases oxygen
. Since oxygen is much less soluble in water than is carbon dioxide, the water quickly saturates with oxygen and bubbles form.
What do Elodea plants eat?
Care: Food: There is no need to feed; Elodea derives most of its nourishment from
the water through its leaves and through light
. Water: You should keep your Elodea fully submerged in water, so water in its habitat should be replenished as it evaporates with de-chlorinated water.
Where can Elodea be found?
Elodea can be found in
wet mud along sluggish streams, seepage areas, and marshes
.
Does elodea produce oxygen?
The
higher the exposure to light the more oxygen bubbles produced
by the Elodea. Light excites electrons from P680. … The removal of electrons splits water into two hydrogen ions and an oxygen atom. The oxygen atom immediately combines with a second oxygen atom to produce oxygen gas.
Is elodea an organism?
Elodea is
a freshwater organism
and should be kept in dechlorinated tap water.
What does elodea produce?
Elodea plants produce
oxygen bubbles
. The elodea is an aquatic perennial plant. When in bloom, elodea produces white, three-petaled flowers that float on the surface of the water. Elodea produces bubbles when it breathes.
What gasses are given off by elodea?
Snails generate
CO2
that elodea convert into sugar. Elodea produces the O2 and glucose that the snail will consume.
What are the two stages where photosynthesis occurs?
There are two main stages of photosynthesis:
the light-dependent reactions and the Calvin cycle
.
What do elodea cells look like?
This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its
box-like shape
. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell.
Which step in photosynthesis does not need light?
The light-independent stage, also known as the Calvin Cycle
, takes place in the stroma, the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light-independent reaction.
Is light required for elodea to take up CO2?
blue (no CO2) is not only dependent on the presence of Elodea, but specifically on the Elodea being supplied with
light
.
What did you observe on the elodea leaves?
The elodea like all green plants uses the process of photosynthesis to produce organic energy molecules. …
Oxygen
can be observed leaving the elodea cells. Under a microscope the green chloroplasts inside of the cell can be observed.
