Lesson #3: Plants Transport System

Vocabulary flashcards covering the components of the plant transport system, specific root types, vascular pathways (xylem/phloem), and the steps of photosynthesis.

Transport System

The mean by which plants move water and food through their body, involving the roots, stem, and leaves.

Roots

Plant organs that take in water and nutrients from the soil and send them up through the stem to the rest of the plant.

Taproot System

A root system characterized by one primary, large central vertical root that grows deep into the soil.

Fibrous Root System

A root system with many smaller secondary roots spreading out near the surface, commonly found in grass or local plants.

Edible Roots

Thickened roots that store nutrients for the plant's growth and are eaten by humans, such as carrots, beets, turnips, onions, garlic, and celery.

Stem

A part of the plant transport system that acts like a highway, carrying water and nutrients from the roots to the leaves.

Xylem

A pathway inside the stem that carries water and nutrients from the roots to the leaves.

Phloem

A pathway inside the stem that moves the food made by the leaves to the rest of the plant.

Leaves

Plant organs that play a key role in making food for the plant using sunlight, carbon dioxide, and water.

Photosynthesis

The process where plants use sunlight, carbon dioxide ($CO_2$), and water to make food.

Chlorophyll

A substance in the leaves that absorbs sunlight to provide energy for the photosynthesis process.

Xylem Vessels

The tubes through which water travels up the stem to reach the leaves during water uptake.

Stomata

Tiny openings in the leaves through which carbon dioxide ($CO_2$) enters from the air.

Chloroplast

The specific part of the plant cell where photosynthesis occurs.

Glucose and Oxygen

The two final products resulting from the process of photosynthesis.

Pechay Leaf

The specific plant material used in the Pathway Inside Plants activity to demonstrate how water moves through the stem.
