Cell Wall
In a crop plant, the three basic tissue types are ________, ________, and _______ _________.
Epidermis, vascular, and ground tissues.
The outermost tissue is the epidermis.
True
The “pipelines” in the plant are known as _________ ________.
Vascular Tissues (Xylem and Phloem)
The _________ conducts water and minerals, and the Phloem transports photosynthetic products from the leaves.
Xylem
The region of active cell division that gives rise to the primary growth of various tissue types are know as the _________.
Meristem
________ meristmes are located at the tip of roots and shoots, whereas axillary meristems are located at the axils of leaves.
Apical
In most crops, the _____ constitute the majority of underground portion of the plant and are specialized for anchorage, absorption, storage, and conduction.
Roots
In monocotyledons, the primary root is usually short-lived and the main root system develop from ________ roots that arise from nodes on the base of the stem below or just above the soil surface.
adventitious
In monocotyledons, no root is more prominent that other others, and the toot system know as the ________ __________ _______.
Fibrous root system
In dicotyledons, the primary root of the embryo forms a substantial, tapering main root from which smaller ______ root usually arise. This type of root system is called a _____ root system.

False
Nodes are points of attachments for leaves on the stem.
True
The regions between successive nodes are called inter-nodes.
Trure
The only function of the stem is water conduction.
False
The tillers are vertical flowering stems of grasses origination from basal nodes.
True
Horizontal above ground stems are called stolons.
False
Horizontal above ground stems are called stolons.
True
Enlarged, fleshy underground stems are called a stolons.
False
