What is photosynthesis 9th grade?
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
What are some questions about photosynthesis?
Photosynthesis test questions
- What is the role of chlorophyll?
- Which useful energy conversion is carried out by chlorophyll?
- What are the products of the light reactions?
- In photosynthesis, what is ATP required for?
- In which cell organelles does carbon fixation occur?
What are the products of photosynthesis quizzes?
Photosynthesis converts radiant energy into chemical energy. Photosynthesis produces carbohydrates. Plants need sunlight, carbon dioxide, water, nutrients, and chlorophyll to complete photosynthesis. Plants use chlorophyll, water, and carbon dioxide to make sugar.
What Colour is chlorophyll?
green color
Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.
Why are plants usually green?
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
Do plants breathe?
Do Plants ‘Breathe’? Yes, like animals plants also breathe. All living organisms, including plants, receive their energy required for their survival from a chain of chemical reactions called respiration.
Why are leaves red?
As some leaves die, they produce chemicals called anthocyanins (also found in the skin of grapes and apples) from built up sugars. These chemicals produce a red pigment that can combine with green pigments left from chlorophyll and display different shades of red.
