Plant Nutrition Lab: Photosynthesis and Proof

Section A: Photosynthesis Equation and Raw Materials

Question 1mcq

Which equation represents photosynthesis?

CO_2 + O_2 \rightarrow H_2O

C_6H_{12}O_6 + O_2 \rightarrow CO_2 + H_2O

6CO_2 + 6H_2O \xrightarrow{light} C_6H_{12}O_6 + 6O_2

H_2O \rightarrow H_2 + O_2

Question 2mcq

What is the main food product formed during photosynthesis?

A.Glucose

B.Bile

C.Lactic acid

D.Urea

Question 3mcq

In the photosynthesis equation, oxygen appears on the product side because:

A.Oxygen is released during photosynthesis

B.Oxygen is changed into chlorophyll

C.Oxygen is absorbed from soil

D.Oxygen is the only raw material

Question 4mcq

Which statement best explains: Identify raw materials for photosynthesis?

A.It describes a process that occurs only in non-living objects.

B.It is a process that happens only in plants and never in animals.

C.Name carbon dioxide, water, chlorophyll and sunlight and their sources.

D.It refers only to reproduction and not to maintenance.

Question 5mcq

A student is revising Nutrition in Plants. Which idea is most accurate for 'Identify raw materials for photosynthesis'?

A.It explains only external body movement, not internal cellular work.

B.It means the organism no longer needs energy.

C.It describes a process that occurs only in non-living objects.

D.Name carbon dioxide, water, chlorophyll and sunlight and their sources.

Question 6mcq

Which answer would best correct a misconception about identify raw materials for photosynthesis?

A.It describes a process that occurs only in non-living objects.

B.It explains only external body movement, not internal cellular work.

C.Name carbon dioxide, water, chlorophyll and sunlight and their sources.

D.It is mainly a chemical test for acids and bases.

Section B: Experimental Evidence

Question 7mcq

Stomata mainly help plants by allowing:

A.Blood clotting

B.Protein digestion

C.Gaseous exchange

D.Urine formation

Question 8mcq

Guard cells control:

A.Heart valves

B.Food movement in oesophagus

C.Opening and closing of stomata

D.Kidney filtration

Question 9mcq

Why is stomatal control useful for plants?

A.It balances gas exchange with water loss

B.It stops photosynthesis forever

C.It transports blood

D.It digests starch
