reinforcement nutrition in plants

Name: Date: Class:

1 Jaime shows his friend Anna the plant he has given his grandmother and asks her for advice on how to make the plant grow strong and healthy. Read Anna’s reply and answer the questions.

a) Do you think this advice could be useful to Jaime so he can take care of his plant? Why?

b) Jaime got a little confused trying to explain to Anna that his plant makes its own food and that it doesn’t need food like Nuca does. Help him by ordering steps 1 to 4.

Raw sap travels through the vessels to the leaves.

It absorbs water and minerals from the soil.

Elaborate sap travels though the vessels to the rest of the plant.

Photosynthesis takes place in the leaves.

c) Where would you place the plant if you were Jaime? Explain your answer.

I don’t know. I fill up Nuca’s food bowl every day, I give him fresh water and I take him for a walk.
