Parts of Plant
Main Parts of Plant
1. Vegetative Part- Organs concerned with the growth & nutrition of the plant- Responsible for the non-reproductive activity
a. Root or Root Systemb. Stemc. Leaves
Main Part of Plant
2. Reproductive Part- Responsible for the production of new individual plant
a. Flowersb. Fruits c. Seeds
VEGETATIVE PART
ROOTS
• For anchoring the plant and absorption of water and mineral
• Cylindrical in form and are usually colorless or have some color
Types of Root System
1. Taproot- Has a primary root
where the lateral root arises
- Typical of the dicot
Types of Root System
2. Fibrous - More or less the same
size originating directly at the base of the stem
- Characteristic of monocot
Type of Root System
3. Adventitious - Arise from any part of
the plant body
Parts of the Root
STEM
- Ascending axis of the plant body for support and conduction
Types of Stem
Herbaceous Stem• Soft and Green• Little growth in diameter• Tissue chiefly primary• Chiefly annual• Covered by an epidermis• Buds mostly naked
Woody Stem• Tough and not green• Considerable growth in
diameter• Tissue chiefly secondary• Chiefly perennial• Covered by corky bark• Buds chiefly covered by
scales
Types of Stem
Herbaceous Woody
Parts of Stem
LEAVES
• Expanded, flat and green• For photosynthesis and transpiration
REPRODUCTIVE PART
Reproductive Part1. Flowers- Modified shoot that bears
the gamete for sexual reproduction
2. Fruits- Ripened ovary- Formed as a result of
union of gametes3. Seeds- Mature ovule- Consist of embryo,
endosperm, cotyledon and seed coat
TYPES OF FLOWERING PLANT
Eudicot / Dicot• Form the largest group of
plants • Netted vein leaf• Flowe parts are in multiples
of 4 or 5• Seeds with 2 cotyledon• Stem is covered with bark
and tiny pores called “ lenticel”
Monocot• Seeds have only one
cotyledon• Parallel vein leaf which are
usually narrow • Floral part is in multiple of 3• Stem do not have lenticel
