Known technically as gymnosperms, they have needle-like leaves which are almost always evergreen and reproduce through exposed seeds nestled within cones.
Sponges have hard structures within their bodies called spicules, crystalline forms made from amorphous silica that grow and branch to form wicked shapes.

Some trees, mostly evergreen conifers like pines or spruce, use solely this technique and keep their needle-like leaves unfrozen year-round with a super strong anti-freeze.
The NDG-based needle sensors and sensor arrays are reliable electrochemical platforms for the detection of SA in plant tissue both in vivo and in vitro.
