Photosyhthesis

Photosyhthesis

Energy:

• Energy for living things comes from food. Originally, the energy in food comes from the sun

PLANTS

• •Organisms that use light energy from the sun to produce food—autotrophs (auto = self)

   Ex: plants and some microorganisms (some bacteria and protists)

• •Organisms that CANNOT use the sun’s energy to make food—heterotrophs

   Ex: animals and most microorganisms

Multiple Choice

What is the ultimate ORIGINAL source of energy for living things

• Sugar
• Sun
• Moon
• Carbon Dioxide

Multiple Choice

Which organisms perform Photosynthesis?

• Only Autotrophs
• Only Heterotrophs
• Autotrophs and Heterotrophs

Photosynthesis:

• •Photosynthesis is the process by which the energy of sunlight is converted into the energy of glucose

• 
  

Plants

• •Photosynthesis occurs in the chloroplasts of plants

• •Light absorbing compound is a pigment—pigments absorb some wavelengths of light and reflect others—the color our eyes see is the color that the pigment reflects

Multiple Choice

Why do plants need sunlight for photosynthesis?

• The light creates heat needed for photosynthesis to occur

• The light provides the energy needed to power photosynthesis

• Plants can't absorb carbon dioxide in darkness

• Plants can't absorb water in darkness

Multiple Choice

Which product is "waste" and mostly released by the producer (plant)?

• oxygen

• carbon dioxide

• sugar

• glucose

Multiple Choice

What are the 2 products of photosynthesis? The products are the things made in the process of photosynthesis.

• water, sunlight

• glucose, carbon dioxide

• oxygen, glucose

• sunlight, oxygen

Multiple Choice

What pigment captures/absorbs sunlight?

• stomata

• chlorophyll

• chloroplast

• phloem

Chlorophyll

• •Chlorophyll is the pigment inside the chloroplast the absorbs light for photosynthesis
