rhizoid

There he discovered that the plant had one cell and the nucleus was always located in the rhizoid.

It is a sessile organism which anchors itself to the soft seafloor using a rhizoid, a root-like structure that embeds into the sea floor.

It lives in soft abyssal sediment at depths between 3316 and 3399 meters and attaches to the seafloor using its root-like rhizoid.

The single nucleus of Acetabularia is located in the rhizoid, and allows the cell to regenerate completely if its cap is removed.

The inner surface of the smooth rhizoids is smooth while that of the tuberculate rhizoid will have internal cell wall projections.

The tip of the germ tube divides to form an octant of cells, and the first rhizoid grows as an extension of the original germ cell.

In addition, if a piece of the stem is removed, with no access to the nucleus in the rhizoid, this isolated stem piece will also grow a new cap.

Not needing the water-drawing roots of more advanced plants, they grow a form of rhizoid that is just a holdfast, letting them cling to rocks and other hard surfaces.

A root hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root.

From the top of the rhizoid, 1 to 6 horizontal, equidistant stolons with vertical branches form the 'vanes' of the sponge (this is evident in all of Chondrocladia).

Further, the fossil gets narrower as it attaches to a rhizoid, a place where one would expect there to be the highest concentration of vascular tissue (as this is where the peak transport occurs).

Acetabularia has three basic parts: its rhizoid, a short set of root-like appendages that contain the nucleus and anchor the cell to fissures in a substrate; its median stalk, which accounts for most of its length; and its apex, where its cap forms.

In form, the mature Acetabularia resembles the round leaves of a nasturtium, is 0.5 to 10 cm tall and has three anatomical parts: a bottom rhizoid that resembles a set of short roots; a long stalk in the middle; and a top umbrella of branches that may fuse into a cap.
