The embryonic root is the structure that will become the root in a mature plant. When it grows out of the seed and into the soil, it grows downward. Its formal name is Radicle.
The embryonic shoot is the structure in the seed that will become the stem of the new plant and grows upward through the soil surface.

The endoplasmic reticulum is a spider web of canals, each canal surrounded by a cellular membrane, that is embedded within the cytoplasm. Ribosomes (protein synthesis factories) typically are attached along the margin of the endoplasmic reticulum.

The epidermis is a layer of cells on the exterior of stems and leaves as well as other plant organs. This is a protective layer that keeps out bacterial and fungal spores as well as sealing the plant organ from loss of water. Cutin, secreted by the epidermal cell, is a waxy material that allows the epidermal cell to be very effective in preventing water loss. In cross section, the epidermis looks like small bricks. Looking at epidermal cells from the top down, they have the appearance of a jigsaw puzzle pieces.

Epigynous ovaries have the flower parts (calyx, corolla, and androecium) attached above the ovary to the top of the ovary. Epigynous and inferior ovary are synonymous terms.

Excurrent branching is the type of branching that exists in a pine tree. There is one main trunk with a whorl of branches at each node. This is also known as Monopodial Branching.
