Where does Chemical Digestion start to happen?

• Mouth

• Stomach

• Large Intestine

• Small Intestine

Which does NOT describe Digestive Glands?

• These are parts where food passes through

• Salivary Glands, Gastric Glands, Liver, and Pancreas are examples of it

• They help with Chemical Digestion

• They release Enzymes

What is the function of Gall Bladder in Human Digestive System?

• It controls the release of Bile produced by the Liver

• It blocks the chyme from entering the Liver

• It protects the Liver from harmful bacteria

• It supplies Bile to the Liver

Which substance produced by Gastric Glands protects the Stomach?

• Mucus

• Hydrochloric Acid

• Pepsin

• Water

In which part of the Digestive System are Feces created?

• Large Intestine

• Small Intestine

• Rectum

• Anus

Which part of the plants Absorb nutrients and water from the soil?

• Roots

• Stelle

• Phloem

• Xylem

What are the 2 Main Parts of Plants?

• Shoot &

  Root Systems

• Stele &

  Roots Systems

• Phloem &

  Xylem

• Midrib &

  Veins

Why does water always move in upward direction in Xylem?

• Because only Roots can absorb water from the environment

• Because the Heat from the Sun causes the water to rise up

• Because the Stomata are located under the leaves of the plant

• Because Xylem counters the force of gravity

Why do nutrients move in up and down directions in the Phloem?

• Because there are nutrients that come from both the roots and leaves

• Because the heat from the Sun causes nutrients to rise up, but gravity pulls them down

• Because the plants need to distribute the nutrients across their body

• Because nutrients can also flow in the Xylem
