Leaf Tissue Organization
The plant body is divided into several organs: roots, stems, and leaves. The leaves are the primary photosynthetic organs of plants, serving as key sites where energy from light is converted into chemical energy.

leaf -- An organ found in most vascular plants; it consists of a flat lamina (blade) and a petiole (stalk). Many flowering plants have additionally a pair of small stipules near the base of the petiole.
leaf veins Vascular tissue in leaves, arranged in a net-like network (reticulate vennation) in dicots, and running parallel (parallel vennation) to each other in monocots.

Leaf Structure of C3 and C4 Plants
The leaves of C4 plants are structured differently than those of C3 plants.
rue leaf. Any leaf produced after the seed leaves (cotyledons).
rugose. A rough appearance of leaves in which veins are sunken and interveinal tissue raised, caused by certain virus infections.
root-leaf-vascular system axis Refers to the arrangement in vascular plants in which the roots anchor the plant and absorb water and nutrients, the leaves carry out photosynthesis, and the vascular system connects the roots and leaves, ...

The fossil leaf they extracted the DNA was from a compression fossil formed when the leaf sank to the bottom of a lake. The conditions were very anoxic (lacking in oxygen) and as a result the fossil was in very good condition.
Growthform: the overall morphology of a plant species, including its stature, leaf type, and habit.
"Apoptosis" is a funny word that is derived from the Latin meaning " to fall off" , like a leaf falls off a tree. And a leaf falls off a tree when it's dead.
The eggs are laid on the leaf. They will crawl around on the leaves and eat on the leaves, and tunnel through the midrib of the leaves sometimes.

Vorticella is a stalked ciliate that is usually found with its based attached to a twig, leaf, or other detritus.
A cotyledon is the seed leaf. When you are a monocot, your seed only has one package of food. "Mono" means one or a single cotyledon. Monocots are made up of simple flowering plants like grasses, corn, palm trees, and lilies.
