Plants Flashcards
Meristematic tissue
Undifferentiated embryonic tissue in the active growth regions of plants
Apical Meristem
In vascular plants, masses of cells in the root and shoot that reproduce and elongate as primary growth occurs
What are the three types of primary meristem, and what do these three lead to?
Protoderm which leads to epidermal tissue.
Ground meristem produces ground tissue.
Procambium produces vascular tissue.
Explain the functions of the three specialized tissues
Epidermal tissue: forms the outer protective covering of a plant
Ground tissue: fills the interior of a plant
Vascular tissue: transports water and nutrients in a plant and provides support.
What is the epidermis covered with and why?
The epidermis is covered with a waxy surface called cuticle, this minimizes water loss. The cuticle also protects against bacteria and other organisms that might cause disease.
Angiosperms
Flowering plant that produces seeds with ovary, which eventually develops into a fruit.
Most flowering plants posses what?
A root system and a shoot system
Root System
Includes the main root and any and all of its lateral (side) branches.
Organ
Combination of two or more different tissues performing a common function.
Stem
Usually the upright, vertical portion of a plant that transports substances to and from the leaves.
Node
In plants, the place where one or more leaves attach to a stem
Internode
In vascular plants, the region of a stem between two successive nodes
Xylem
Vascular tissue that transports water and mineral solutes upward through the plant body; contains vessel elements and tracheids
Phloem
Vascular tissue that conducts organic solutes in plants
Axillary bud
Bud located in the lateral part of the leaf
