Misconceptions on the Concept of Photosynthesis and Plant Respiration for Class at Smp Negeri 27 Medan in science Learning
Type: Empirical
Data collection method: Test
Number of subjects, range: Large — 31 or more
Grade and age of subjects: 6th-8th grade — under 13-14 years
- Respiration in plants requires sunlight but animals do not need it.
- Respiration in animals produces energy but in plants, it does not.
- Respiration in plants only occurs at night but all the time for animals.
- Plants absorb oxygen at night so they should be placed outdoors. Meanwhile, during the day it releases oxygen so it can be placed indoors because it does not compete with other organisms for oxygen.
- Respiration in plants requires chlorophyll but not in an animal.
- The parts of plant cells that can capture sunlight to carry out photosynthesis are plastids.
- The characteristics of the light reactions in photosynthesis are the conversion of light energy into chemical energy.
- In photosynthesis, oxygen is produced. The oxygen released comes from the light and dark reactions in photosynthesis
- The function of chlorophyll in the process of photosynthesis is to absorb sunlight, especially green light
- Animals breathe but plants carry out photosynthesis.
