Scientific Question

• How does chlorine effect seed germination?

3
Hypothesis

• The seed with the least chlorine will grow the
  most.

4
What is chlorine?

• Chlorine is a halogen element that is
  greenish-yellow, incombustible water soluble
  ,poisonous gas that is highly irritating to the
  respiratory organs. Obtained chiefly by
  electrolysis of sodium chlorine brine It is used
  for water purification, in both of chemicals that
  do not contain chlorine as ethylene glycol, and
  of those that do.

5

• Seed germination is to start the sprout to
  develop into a plant or individual as a seed
  spore or bulb.

6
What makes me interested in this project?

• I am interested in this project because I would
  like to know if seeds at a consistent pace if it
  receives water with chlorine in it.

7
The positive uses of chlorine

• Disinfect
• Purifier

8
The negative uses of chlorine

• Can be used to create a poisonous mixture.
• Stops plants from growing.
• Changes color of colored clothing

9
The 6 parts of a plant that it uses to gain
germination

• Radical-A rudimentary root .
• Cotyledon- The primary leaf of the embryo of seed
  plants
• Hypocotyls - The part of a plant which forming a
  connection with the radical.
• Plumose-the bud ascending axis of a plant while
  still in the embryo.
• Leaf- One of the expanded,Green organ born by the
  stem of a plant.
• Epicotyls - (In the embryo of a plant)that part
  of a stem above the cotyledons

10
What happens to a seed if you put to much chlorine

• To much chlorine on one seed may cause the seed
  to have slower growth rate or to not grow at all.

11
Did you know

• Chlorine is not the only killer of plants there
  are others like over watering, no soil or
  sunlight, So these are some of the many things
  that can kill a seed or stop it from growing

12
Introduction

• Chlorine can often be found in may household
  products,it can usually be found on bleach.
• Chlorine is used to clean pools, wash clothes ,
  etc.

13
Body

• A seed can absorb nutrients in its growth
• Anything poisonous can kill a seed or stop it
  processing.

14
conclusion

• I have learnt that chlorine has its good and bad
  effects it can kill any living thing and if can
  disinfect bacteria.
• The seed can obtain resources to help it go
  through it growth process or stages.
