Question 5
Which statement about the chloroplast is correct?
The right answer is the one marked above.
It is a double-membraned organelle found only in plant cells. The green pigment inside it is chlorophyll — the organelle and the pigment are different things.
In activity 2.1 you watch the chloroplasts of a hydrilla leaf move towards the light. An organelle that aims itself is not a passive container.
