Nutrient Absorption & Transport

Front

What is nutrient absorption?

Back

Nutrient absorption is the process by which living organisms take in nutrients from their environment, typically through their digestive system or cell membranes.

What is the role of diffusion in gas transport?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. In animals, gases like oxygen and carbon dioxide are transported to and from the bloodstream via diffusion.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, including the release of oxygen and the intake of carbon dioxide.

Front

What is xylem?

Back

Xylem is a type of tissue in vascular plants responsible for the transport of water and dissolved minerals from the roots to the rest of the plant.

Front

What is phloem?

Back

Phloem is a type of tissue in vascular plants that transports sugars and other metabolic products downward from the leaves.

Front

How do plants absorb water?

Back

Plants absorb water primarily through their roots, which then transport it through the xylem to the leaves and other parts of the plant.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the significance of minerals like nitrogen for plants?

Back

Minerals like nitrogen are essential for plant growth as they are key components of amino acids, proteins, and nucleic acids.

Front

How does glucose move through plants?

Back

Glucose is transported through the plant via phloem, which distributes the sugars produced during photosynthesis to various parts of the plant.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
