How plants use Carbohydrates

What is the main purpose of nectar in flowers?

• To provide food for the plant
  

• To attract pollinators
  

• To store water
  

• To make seeds

What is nectar made from?

• Water and minerals
  

• Glucose and other sugars
  

• Proteins and fats
  

• Starch and cellulose

Why do plants make amino acids?

• To attract insects
  

• To make proteins
  

• To store energy
  

• To make nectar

What will happen if a plant cannot get enough nitrogen from the soil?

• It will make more nectar
  

• It will grow faster
  

• It will not make enough proteins and will not grow strongly
  

• It will produce more glucose

What is chlorophyll?

• A protein
  

• A sugar
  

• A green pigment
  

• A mineral

Why are the leaves orange?

• They have too much chlorophyll
  

• They do not contain enough minerals to make chlorophyll
  

• They are old leaves
  

• They have too much glucose

What happens if a plant cannot make chlorophyll?

• The plant will grow faster
  

• The plant will not be able to photosynthesize well and will not grow well
  

• The plant will produce more nectar
  

• The plant will make more amino acids

What are the two main products of photosynthesis?

• Oxygen and carbon dioxide
  

• Glucose and oxygen
  

• Water and glucose
  

• Starch and sucrose

Why do plants store glucose as starch?

• Starch is easier to transport
  

• Starch is soluble in water
  

• Starch does not get involved in chemical reactions inside plant cells
  

• Starch is used directly for energy

What is one use of glucose in plants?

• To absorb sunlight
  

• To build protein molecules for growth
  

• To produce oxygen
  

• To make cell walls directly
