What of these is needed for photosynthesis to begin?
A
oxygen
B
carbon dioxide
C
sunlight or radiant energy
D
all of these
Explanation: 

Detailed explanation-1: -To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

Detailed explanation-2: -The radiant energy of the Sun provides the energy for the process of photosynthesis. During the reactions of photosynthesis, solar energy transfers to chemical energy and stores in the bonds of carbohydrates, such as glucose.

Detailed explanation-3: -Radiant-Radiant energy means light. Examples of things that have radiant energy are the Sun, lightbulbs and our computer screens. Plants convert light energy into chemical energy (food) which helps them to grown, this is known as photosynthesis. Sound-The louder we shout the more sound energy we are using.

Detailed explanation-4: -ATP. Hint: In plants, the radiant energy from the sun will be converted into chemical energy to that of glucose (sugar). This transformation is called photosynthesis. Plants use water, carbon dioxide, and sunlight and transform these into oxygen and glucose.

Detailed explanation-5: -The electromagnetic energy of sunlight is converted to chemical energy in the chlorophyll-containing cells of photosynthetic organisms. In eukaryotic cells these reactions occur in the organelle known as the chloroplast. In the chloroplast, chlorophyll is the pigment that absorbs the sunlight.
