Title: PHOTOSYNTHESIS
1PHOTOSYNTHESIS
- Unit Target Use a model to illustrate how
photosynthesis transforms light energy into
stored chemical energy.
2Learning Target Model ATP production and use.
(skill)
- Energy
- a. Comes from the sun
- b. Is used by plants to grow
- c. Is used by animals for daily activities
- d. Is the ability to do work
- e. All of the above
- Answer e
3Truth and Baloney
The original source of energy for most living
things is water. Baloney Sun Organisms that
can make their own food from the suns energy are
called heterotrophs. Baloney Autotrophs
4ATP
- Which is not a component of ATP?
- Adenine
- Glucose
- Ribose
- Phosphates
- b. Glucose
5- Which component of ATP is missing from ADP?
- A- Adenine
- B- Ribose
- C- 2 phosphates
- D- 1 phosphate
- D- 1 phosphate
6- Energy is released from ATP when bonds break
between - adenine
- ribose
- phosphate groups
- c
7- ATP is
- Light energy
- Mechanical energy
- Chemical energy
- Heat energy
- c.
8- Which is not true about ATP
- It stores energy
- It releases energy
- It is used for active transport of substances
into and out of the cell - It is used for diffusion and osmosis
- d. Diffusion and osmosis do not require energy.

11- Where do the light dependant reactions take
place? - The thylakoid
- Where do the light independent reactions take
place? - The stroma
12Photosynthesis takes places in a plant cells
mitochondria. Baloney chloroplast A plant
needs carbon dioxide, water and sunlight to carry
out photosynthesis. Truth
13- Autotrophs can convert the sunlight into
mechanical energy. - Baloney chemical
- The chemical energy made by autotrophs are
carbohydrates such as sugar and starch. - True
14Learning Target Write the chemical formula for
photosynthesis. (knowledge)
- Name the missing parts of the formula from left
to right. - light
- 6CO2 6H2O --------? 6O2 C6H12O6
15- Heterotrophs rely on photosynthesis for the food
and oxygen produced. - True
16Learning Target Observe changes in a system
during photosynthesis. (R)
- How will photosynthesis be affected if you do not
give a plant light? - Photosynthesis cannot take place without light.
- What will happen to the rate of photosynthesis if
you increase the amount of carbon dioxide
available? - It will increase.
17Learning Target Determine the structures of a
plant that helps it obtain energy. (knowledge)
- Which part of the plant is absorbing water?
- A- roots
- What plant part is absorbing sunlight?
- E- leaf
- What plant part of the plant takes in carbon
dioxide? - Leaf
18- What type of cell is show in the picture?
- Guard cell
- On a hot day, guard cells (open / close ) the
stoma to keep too much water from leaving the
plant. - What gases important to photosynthesis pass
through the stoma? - Carbon dioxide and oxygen
19- The organelle of the leaf that is the site of
photosynthesis is the nucleus. - False chloroplast
- The pigment in the chloroplast that absorbs
sunlight is called xanthophyll. - False chlorophyll
- During the winter, chlorophyll begins to
disappear from the leaf as photosynthesis
production shuts down. - True
