Why does a Venus Flytrap have spikes?

Answer 1

Those spines create a 'cage like structure' to enclose its pray in. When a fly enters one of the Venus Flytrap's trigger mouths, the cage closes in on the fly and slowly digests it over the course of around 10 days.

Answer 2

The 'spikes', or cilia, are there to prevent the trapped prey from escaping after it is caught. They interlock with their counterparts on the other side when the trap closes.

Answer 3

The small spikes inside the "trap" of the plant are the actuator hairs, once a fly or small insect has moved these a few times the "trap" is activated and closes on the insect.

Answer 4

for eating insects and it gets its food from oxygen (other insects )
