EXPERIMENT: PHOTOSYNTHESIS PROCESS1. Boil some water in a beaker.2. Put 1 variegated leaf into the water and boil for 3 min. 3. Turn off the flame (Bunsen burner).4. Fill the boiling tube with methylated spirit and put the

boiling tube into the hot water.5. Soak the boiled leaf into the methylated sprit.6. When methylated sprit turns green, wash the leaf in the

water.7. Dry the leaf on a paper towel. 8. Drop some iodine on the leaf.

Chemicals:

• Iodine (brown solution) turns blue-black in the presence of starch.

• Methylated sprit is volatile, therefore catches fire very easily(flammable).

Which part of the plant?1. The main site for photosynthesis2. Attaches the leaf to the stem3. Attachment site for leaves4. Where water is absorbed by the plant.

It also anchors the plant in the soil.5. Special cell of the root which absorbs

water for the plant6. Holds the male and female

reproductive organs. Where sexual reproduction occurs.

Which part of the plant?1. The main site for photosynthesis: Leaf2. Attaches the leaf to the stem: Petiole3. Attachment site for leaves: stem 4. Where water is absorbed by the plant. It

also anchors the plant in the soil: root 5. Special cell of the root which absorbs

water for the plant: root hair6. Holds the male and female reproductive

organs. Where sexual reproduction occurs: flower

Leaf transverse section

Outer layer of the leaf

CUTICLE- A waxy layer- It is a transparent layer which

allows light to penetrate the leaf

- It reduces water loss

Outer layer of the leaf

EPIDERMIS- The outer layer of cells is called

epidermis- The epidermal cells are transparent so

that light can penetrate to the inner part of the leaf

- These cells also help support the leaf and protects the leaf from physical damage.

Outer layer of the leafStomata and Guard cells- Pores in the leaf surface are called stomata.

(sig. stoma)- The stomata is formed by two two kidney

shaped cells called guard cells which can change their shape to open and close the stomata.

- Stomata and allow gases to enter and leave the leaf.
