What is osmosis?

Back

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

Front

What does xylem transport?

Back

Xylem transports water and minerals from the roots to the rest of the plant.

Front

What is phloem responsible for?

Back

Phloem is responsible for transporting food materials (sugars) from the leaves to other parts of the plant.

Front

What are vascular tissues?

Back

Vascular tissues are specialized plant tissues that conduct water, nutrients, and food throughout the plant. The two main types are xylem and phloem.

Front

How do plants lose water?

Back

Plants lose water primarily through small openings called stomata, which are located on the leaves.

Front

What is transpiration?

Back

Transpiration is the process by which water vapor is released from the plant into the atmosphere, mainly through stomata.

Front

What role do stomata play in plants?

Back

Stomata are tiny openings on the surface of leaves that allow for gas exchange (CO2 in, O2 out) and water loss through transpiration.

Front

What is the function of chlorophyll?

Back

Chlorophyll is the green pigment in plants that absorbs light energy for photosynthesis, allowing plants to convert sunlight into chemical energy.

Front

What is active transport in plants?

Back

Active transport is the process by which plants move ions and nutrients against their concentration gradient, requiring energy.

Front

What is the significance of root hairs?

Back

Root hairs increase the surface area of roots, enhancing the plant's ability to absorb water and nutrients from the soil.
