Three Basic Organ in Plant

• Three basic organs evolved roots, stems, and
  leaves
• They are organized into a root system and a
  shoot system

The Three Basic Plant Organs Roots, Stems, and
Leaves

• The basic morphology of vascular plants
• Reflects their evolutionary history as
  terrestrial organisms that draw nutrients from
  two very different environments below-ground and
  above-ground

Roots

• A root
• Is an organ that anchors the vascular plant
• Absorbs minerals and water
• Often stores organic nutrients

Fungsi Akar

• Attachment to substrate (ground, etc)
• Water and nutrien uptake
• Transport
• In several plants
• Food storage
• Oxygen uptake
• Climber

• In most plants
• The absorption of water and minerals occurs near
  the root tips, where vast numbers of tiny root
  hairs increase the surface area of the root

Primary Growth of Roots

• The root tip is covered by a root cap, which
  protects the delicate apical meristem as the root
  pushes through soil during primary growth
• The primary growth of roots
• Produces the epidermis, ground tissue, and
  vascular tissue

12

• Lateral roots
• Arise from within the pericycle, the outermost
  cell layer in the vascular cylinder
