Plant Organ Classification
Stem
Function: The stem connects the roots and leaves, supports the plant structure, and transports water and nutrients.
Characteristics: Can be woody or herbaceous, with growth points and lateral branches.
Fruit
Function: Fruits are reproductive structures that protect seeds and aid in their dispersal.
Characteristics: Mature ovaries that usually contain seeds, varying in shape and size.
Root
Function: Roots anchor the plant in the soil, absorb water and minerals, and store nutrients.
Characteristics: Usually grow underground, divided into main roots and lateral roots, with root hairs to increase absorption surface area.
Leaf
Function: Leaves are the primary sites for photosynthesis, absorbing sunlight and converting carbon dioxide and water into glucose and oxygen.
Characteristics: Typically flat, with a surface containing stomata for gas exchange.
Trunk
Function: The trunk is the main support structure of woody plants, bearing the weight of the crown and providing stability for growth.
Characteristics: Typically thick and woody, with growth rings and bark.
Spike
Function: A spike is a specific type of inflorescence structure responsible for plant reproduction.
Characteristics: Composed of multiple tightly clustered small flowers, usually growing at the top or sides.
Tuber
Function: Tubers are storage organs that store nutrients and water for the plant to use in unfavorable conditions.
Characteristics: Typically fleshy underground parts, such as potatoes.
Flower
Function: Flowers are the reproductive organs of plants, responsible for producing seeds and fruits.
Characteristics: Composed of petals, stamens, and pistils, with diverse shapes and colors to attract pollinators.
