A questionnaire was distributed to grade
9 students (14-15 years old) in turkey.
A questionnaire was constructedcomprising seven open-ended questions
design to test students conceptionabout important areas of plant biology.

Photosynthesis: process that coverts light
energy into chemical energy of sugars
and oth
er organic compound in greenplant.
Nutrition: process by which an organism
obtains food which is used to provideenergy and materials for its life sustaining
activities.

What is thesource ofweight
increase in
plants during
their growth?
Most ofstudentanswer water
and soil, 7
student
mentionedcarbon
dioxide.
The weightincrease inplants comes
from organic
substances,
manufactured by the
plantsthemselves.

why are
plantscalledproducers?
Plants are called
producers becausethey produceoxygen. On the otherhand, about half of
students claimed thatmost plants producefruit or vegetables, socan be called
producers.

Question Result
Is it possible for animals
to survive with
out plantsin an ecosystem?
Most students believed
th
at animals need plantto survive but only 22students (25%) relate thiswith the process of
photosynthesis.
What is the reason forkeeping carbon dioxide
at an optimum level inthe atmosphere, eventhough living organismbreath it continuously?
Approximately 52students understand the
role of carbon dioxide inphotosynthesis, butremaining 36 students dinnot give accurate
answer for this question.

Many students do not understand that plants absorbcarbon dioxide and water to produce organicmaterials.
Most of students have misconception that livingorganisms obtain energy by means other than byphotosynthesis or food intake.
Students understand the need for water, air andsunlight by plants. But they fail to understand why
these materials are important and how they are partof the production of food.
