stoma

epidermis layer

spongy and palisade mesophyll

cuticle

Question 6 of 10

6. Lamella is the name for an unstacked thylakoid. What do lamellae connect together? Hint

two chlorophylls

two guard cells

two grana

two chloroplasts

NEXT>

Question 7 of 10

7. Leaves are usually broad and thin or narrow and thin. This allows the oxygen to travel shorter distances to reach the chloroplasts.

True

False

NEXT>

Question 8 of 10

8. Inside of the thylakoid there are various parts which are very important to photosynthesis. Which of the following is NOT a part of the thylakoid? Hint

they're all a part of the thylakoid.

thylakoid radiation site

thylakoid membrane

NEXT>

Question 9 of 10

nutrients and water

water and nutrients

sun and soil

soil and sun

NEXT>

Quiz Answer Key and Fun Facts

1. The very top of the leaf has a thin coated waxy surface. What is the name of this leaf part?

Answer: cuticle

The major function of the cuticle is to control the amount of light which goes into the leaf, and the amount of water which goes out. On a hot, dry, sunny day for example the leaf will not let as much water out or sunlight in.

2. This leaf part is transparent. It allows light to pass through to the section where most of the photosynthesis reaction takes place. What is the name of this colourless leaf part?

Answer: epidermis layer

The epidermis layer is located below the cuticle in not only the leaf but also the stem and root.

3. All living plants, no matter their age, colour, maturity, or size have chlorophyll in their leaves.

Answer: False

Chlorophyll begins the process of photosynthesis and without it photosynthesis would not occur. However, chlorophyll is a green-coloured pigment and not all plants are green. Non-green plants have carotenoids which reflect or transmit photons in yellow, orange, and red.

4. Microscopic openings in the leaf regulate the gas exchange of carbon dioxide and oxygen. They also allow transpiration of the leaf to occur. What is this opening called?

Answer: stoma

The guard cells surround the stoma and allow them to open and close. For example, the stoma is larger and more open when the guard cells are swollen. When the guard cells are flaccid the stoma closes.

5. In which part of the leaf are chloroplasts most abundant?

Answer: spongy and palisade mesophyll

The mesophyll layers are located under the cuticle and epidermis layer and are the bulk of the leaf.

6. Lamella is the name for an unstacked thylakoid. What do lamellae connect together?

Answer: two grana

A grana is a stack of thylakoids. These stacks are connected to one another and that's done by the lamellae.

7. Leaves are usually broad and thin or narrow and thin. This allows the oxygen to travel shorter distances to reach the chloroplasts.

Answer: False

The shape of the leaf allows it to have a maximum absorption of sunlight and limits the distances that absorbed carbon dioxide needs to travel to reach chloroplasts. Oxygen is a product of photosynthesis.

8. Inside of the thylakoid there are various parts which are very important to photosynthesis. Which of the following is NOT a part of the thylakoid?

Answer: thylakoid radiation site

The thylakoid significantly increases the efficiency of photosynthesis because of the increase of surface area they provide.

9. The vascular bundles carry materials needed for the plant through the roots to the leaves. What do the xylem and phloem carry respectively?

Answer: water and nutrients

The xylem carries water from the roots to the leaves, while the phloem carries nutrients and minerals from the soil through the roots. The xylem is larger in radius than the phloem.

10. Chlorophyll is located inside the chloroplast.

Answer: True

Chloroplasts are the so called "factories" of photosynthesis for plants. They contain stroma, thylakoids, lamellae, and chlorophyll. Most of the stages of photosynthesis happen in the chloroplast.
