Plant Question?

Question

All off the following are movements plants can accomplish except:

1 folding and unfolding of leaves
2 rapid responses using action potentials
3 growth movements up or down in response to gravity
4 growth movements toward or away from light
5 changes in plant growth in response to touch

I think it is 4 because of phototropism, am I correct
(doubts in 3 and 4)

Thank You

Answer 1

It wouldn't be 4, because this is something plants CAN do. Phototropism is the name given to growth toward/away from light.

I'd say 2. Action potential implies something that has a nervous system/neurons.

Plants do fold and unfold leaves (Prayer plant, sensitive plant, Venus flytrap) (eliminates #1)

Plant shoots grow upward and roots (at least taproots) grow downward (eliminates #3)

Phototropism eliminates #4

Venus flytrap and sensitive plant close their leaves when touched (eliminates #5)

So #2 is the only one left.

Answer 2

The previous response is very good

Yep, You can exclude #2
Action potentials would refer to nerves and muscles,
which plants don't have.

Answer 3

They can do all of them I think
