IG8.2&8.3 Translocation and Amino Acids Flashcard

Front

Where are phloem and xylem located in roots?

Back

In the center.

Front

What are the elements found in the Phloem?

Back

Tissue companion cells, fibers, sclereids, laticifers, and parenchyma cells.

Front

What is the function of the cortex of the root?

Back

Storage, support, and movement of minerals and water.

Front

How does osmosis contribute to water movement in plant roots?

Back

Water follows ions and flows into the root due to the accumulation of minerals beyond the impermeable membrane due to active transport.

Front

What part of the root allows water and minerals to enter?

Back

Root hairs.

Front

What is the primary function of phloem in plants?

Back

Transport of sugars and nutrients produced by photosynthesis.

Front

What role do root hairs play in plant nutrition?

Back

They increase the surface area for absorption of water and minerals.

Front

Define active transport in the context of plant roots.

Back

The movement of ions against their concentration gradient, requiring energy.

Front

What is the significance of the epidermis in roots?

Back

It serves as a protective outer layer and regulates water and nutrient absorption.

Front

Explain the process of transpiration in plants.

Back

The loss of water vapor from plant leaves, creating a negative pressure that helps draw water up from the roots.
