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.

Question Misconception Concept

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.

Question Misconception Concept

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.
