4 major angiosperm organs

Roots, Stems, Leaves, Flowers

Front

Function of organs in plants

Back

Organs function together to create organ systems: Root system (roots) and Shoot system (stems, leaves, flowers)

Front

Vascular tissue in plants

Back

Connects root and shoot systems. Roots rely on sugar from photosynthesis in shoots; shoots rely on water and minerals from roots.

Front

Importance of roots

Back

Vital for below ground resource extraction and dealing with gravity. Absorb water and minerals, anchor plant to soil.

Front

Types of root systems

Back

Tap root system (tall plants) with tap root and lateral roots; Fibrous root system (small plants) where tap root dies and lateral roots grow.

Front

Root hairs

Back

Main absorptive part, located at tips of absorptive roots, increase surface area.

Front

Mycorrhizal fungi

Back

Associate with the roots of most plants.

Front

Structure of stems

Back

Branching structure with nodes (leaf attachment points), internodes (stem segments between nodes), apical bud (elongation of young shoot), and axillary bud (potential to form lateral branch, thorn, or flower).

Front

Functions of stems

Back

Support leaves, flowers, and fruits; transport water and minerals to supported structures and bring sugars to cells.
