100

This is the process by which molecules move from an area of high concentration to an area of low concentration.

Diffusion

100

What is transpiration?

This process involves the loss of water vapor from the plant's leaves.

100

This blood cell type has no nucleus and is shaped like a biconcave disc.

Red Blood Cells

100

These blood vessels carry oxygenated blood away from the heart.

Arteries

100

This is the muscular chamber of the heart that pumps oxygenated blood into the aorta.

Left ventricle

200

This term describes the movement of water molecules across a semi-permeable membrane.

Osmosis

200

The tissue that transports water and minerals from the roots to the rest of the plant is called this.

Xylem

200

This component of blood helps in clotting and stopping bleeding.

Platelets

200

Name three substances that are exchange via the capillaries

gases- carbon dioxide, oxygen, nutrients, hormones

200

The heart has four chambers, and this one receives deoxygenated blood from the body.

Right atrium

300

When a cell is placed in a hypertonic solution, it will undergo this process, resulting in the shrinkage of the cell

Plasmolysis

300

What are phloem tubes?

This tissue transports the products of photosynthesis, such as sugars, throughout the plant.  

300

The liquid portion of blood that carries nutrients, waste products, and gases is called this.

Plasma

300

This large artery carries oxygenated blood from the left ventricle to the rest of the body.

Aorta

300

This valve prevents the backflow of blood from the left ventricle to the left atrium.

Bicuspid valve (mitral valve)

400

This factor does NOT affect the rate of diffusion: temperature, concentration gradient, or size of the solute.

Size of the solute

400

This type of plant adaptation reduces water loss by minimizing the surface area of leaves.

Having needle-like/ spike leaves.

400

Where are the blood cells made?

In the bone marrow

400

All types of this blood vessel carries deoxygenated blood except which one?

Pulmonary vein

400

Of all the 4 chambers of the heart, the walls of this chamber is the thickest.

Left ventricle

500

What is meant by the 'net movement of water'?

The overall direction and amount of movement of water

500

In some desert plants, this adaptation helps them to lose less water by closing their __________________ during the hottest part of the day.

Stomata

500

The oxygen-carrying pigment in red blood cells.

Haemoglobin

500

True or false: All blood vessels contain valves except veins.

False

500

What is pulmonary circulation?

The part of the circulatory system that moves deoxygenated blood from the heart to the lungs for oxygenation, and then returns the oxygenated blood back to the heart
