1.

What is photosynthesis?

a)

Synthesizing molecules of water

b)

Synthesis of ATP

c)

The process by which a living plant makes food in presence of chlorophyll, light, water, and CO2, releasing O2

2.

Which of these is NOT a factor affecting photosynthesis

a)

Light intensity

b)

Water content

c)

CO2 concentration

d)

Siza of vacuoles

3.

What is translocation?

a)

The movement of food to various parts of the plant via phloem

b)

The loss of water in a plant through cuts

c)

The upward movement of water through the xylem

d)

None of the above

4.

Which of these is NOT an adaptation made in leaves to facilitate photosynthesis?

a)

Large surface area

b)

Needle-like leaves

c)

Numerous stomata

d)

Higher concentration of chloroplasts

5.

Pick the correct order of options:

1- CO2 diffuses into the leaf through stomata and water is taken in through the roots
