Unit 2.4 How do Plants Function?

What is a autotroph?

• an organism that eats other organisms for energy

• an organism that creates it energy from the environment

• organism that acts like a parasite

• organism that hibernates

Most organisms on earth break down glucose to release energy (ATP), which type of organism do we consider these?

• parasites

• virus

• heterotroph

• autotrophs

if you were to place an insect in a sealed jar, and left some food for the insect, which gas would be used by insect to breakdown the food. Which gas would be released after it breaks down the food?

• Carbon Dioxide, oxygen

• oxygen, carbon dioxide

• argon and carbon dioxide

• none of the above

How are the processes of photosynthesis and cellular respiration interrelated?

• The products of photosynthesis are the reactants of cellular respiration

• The reactants of photosynthesis are the products of cellular respiration

• Photosynthesis uses light and cellular respiration creates light

• none of the above

What will happen to a plant that is kept in complete darkness? What is the plant not able to produce?

• it will live, its producing sugar

• it will die, it is not producing sugar

• it will die, it is producing sugar

• The roots will soak up water and the leaves will make sugar

These structures form openings on the leaf that allow for transpiration and gas exchange.

• chloroplasts

• mitochondria

• guard cells

• cytoplasm

Plants remove this gas from the atmosphere and use it to create sugar during photosynthesis

• oxygen

• carbon dioxide

• glucose

• nitrogen

When we use cellular respiration we break down ________ to get ________ which releases energy

• glucose; ATP

• carbon dioxide; ATP

• ATP; glucose

• Oxygen; glucose

Cells can move about, but how do they produce the energy to move?

• cells produce sugars by photosynthesis and release energy by respiration

• cells create high energy proteins that move the cell

• cells produce ATP in the mitochondria, then bonds in the ATP are broken to release energy

• cells move by pumpin charged particles across their membrane

What does the chloroplast make for a plants root system?

• ATP

• chlorophyll

• glucose

• none of the above
