A way to describe the first leaves that grow after cotyledon leaves. These leaves are usually different from the cotyledon leaves. See also, Cotyledon, Monocotyledon' and Dicotyledon.

Tuber
A tuber is a swollen part of the root of a plant, which stores food for dormant plants. These tubers often have buds, or eyes from which a new plant can be grown, for example, potatoes.

Turf
Turf is a patch of grass which has been cut out from the ground, so it can be laid elsewhere. Usually turf comes in rolls which are then laid out to become a lawn.
