Definitions and functions of various plant organs, including roots, stems, and leaves. Learn about their main functions, structures, and the role of plant tissues such as dermal, vascular, and ground tissues.

What you will learn

  • What are the three main functions of roots?
  • What is apical dominance and how does it affect plant growth?

3 types of plant organs

roots, stems and leaves TERM 2

roots

DEFINITION 2 are multicellular organs with three main functions;anchoring the plantabsorbing minerals and waterstoring organic nutrients TERM 3

Stem

DEFINITION 3 consists of alternating system of nodes and internodes, axilarry and apical. TERM 4

apical nodes

DEFINITION 4 cause elongation TERM 5

axilarry nodes

DEFINITION 5 can form branches

leaves

main photosynthetic organ of most vascular plants.monocots and eudicots differ in arangement of veins TERM 7

plant tissues

DEFINITION 7 dermal, vascular and ground tissues are in each organ TERM 8

dermal tissue

DEFINITION 8 in non-woody plants it consists of the epidermis. it is the outermost layer TERM 9

cuticle

DEFINITION 9 waxy coating that prevents water loss on top of dermal tissue TERM 10

vascular tissue

DEFINITION 10 Xylem- water and dissolves mineralsPholem-transports organic nutrients to where they are needed.innermost tissue layer

secondary growth

(getting fat) occurs in stems and roots of woody plants due to cell division of vascular and cork cambium TERM 17

vascular

cambium

DEFINITION 17 adds layers of secondary xylem (wood) and secondary phloem TERM 18

cork

cambium

DEFINITION 18 replaces the epidermis with periderm, which is thicker and tougher TERM 19

pericycle

DEFINITION 19 lateral roots rise from within the preicycle, the outermost cell layer in the vascular cylinder
