Formative assessment 

unit 5 Plants

How to study for the test:

1. Read the text carefully (as well as the text in your textbook)
2. Look at the figures; can you explain what every figure shows?
3. While studying: connect the text with the figures.
4. In this Lesson up: choose the very best answer.
5. Only when the answer is correct (and the answer and feedback "sounds the same as what you were thinking", you know for sure you have the proper knowledge about that subtopic. (Be honest to yourself!)

upside of the leaf

The upside of the leaf is called epidermis.

Cross section with xylem and phloem vessels!

Stoma(ta)

Most of them present at the underside of the leaf.

Here, during the day, oxygen leaves the plant and carbon dioxide enters (during more photosyntesis than respiration).

At night, when there is no light, here oxygen enters the leaf and carbon dioxide leaves.

Bladgroenkorrel

Groene korrels in plantencellen zijn bladgroenkorrels. Hierin gebeurd fotosynthese.

Xylem vessels transport:

1. water and sugar from the roots to the leaves
2. water and minerals from the leaves to the roots
3. water and sugar from the leaves to the roots
4. water and minerals from the roots to the leaves

Phloem vessels transport:

1. water and sugar from the roots to the leaves
2. water and minerals from the leaves to the roots
3. water and sugar from the leaves to the roots
4. water and minerals from the roots to the leaves

Absorption and transport by roots

What do roots take in from the soil?

1. Water and minerals
2. Water, minerals and vitamins
3. Minerals and vitamins
4. Only water

What is the name of the thin hairy structures connected to the smallest roots?

Do you remember this?

Root hairs absorb water with minerals.

This is transported from the xylem vessels (houtvaten) to the rest (omHoog) of the plant.

How to transport water and minerals upwards?

The most important way related to what you have to learn is:

Water with minerals is transported by xylem vessels. Water evaporation causes water (with minerals) to be taken in by the root hairs (the chain of water particles is pulled upwards)

Explain the difference between sexual and a-sexual reproduction

Imagine a plant in a closed box made of glass. This box is standing in the light.
What is formed in this box? Why?

Imagine a plant in a closed box made of glass. This box is standing in the dark.
What is formed in this box? Why?

Parts of flowers are: eggcell, stamen, pistil and pollen grains.
What is the name of the female reproductive organ of a plant (1)? What is the name of the female gamete? (2)

1. 1 = pistil, 2 = egg cell
2. 1 = pistil, 2 = pollen grain
3. 1 = stamen, 2 = egg cell
4. 1 = stamen/ 2 = pollen grain

The fungus causing elms' disease, is spreading through the xylem vessels into the tree. the xylem vessels get blocked and within a year, the tree dies.
Due to the blocking of the xylem vessels, certain substances cannot be transported.

By blocking xylem vessels it is impossible to transport:

1. water and sugar
2. water
3. minerals
4. water and minerals

By making holes in the stem of corn plants, caterpillars disturb the transport of water, minerals and sugars.

In which type of vessels transport is disturbed?

1. Only in phloem vessels
2. Only in xylem vessels
3. Both in phloem vessels as in xylem vessels

Wat is pollination?

1. At pollination, pollen ends up on the stamen of the same species
2. At pollination, pollen ends up on the pistil of the same species
3. At pollination, pollen ends up on the stigma of the pistil of a flower of the same species
4. At pollination, the nucleus of a pollen grain fuses with the nucleus of an egg cell.

Fertilisation

Pollination

What is fertilisation (bevruchting)?

1. When a plant developed fruits
2. When the nucleus of a pollen grain fuses with the nucleus of an egg cell
3. When a pollen grain sticks to a stigma of the same species
4. When seeds are formed.

1. stamen
2. anther

1. Fertilisation
2. Pollination
3. Plant sex

1. the anther
2. the ovary
3. the style
4. the filament

1. the ovule

Why do butterflies fly from flower to flower?

1. To fertilize the plant
2. To drink nectar
3. To disperse the seeds

A plant needs "flavonoïd" to form pollen tubes. During a research a certain type of flower is pollinated with pollen grains without flavonoïd. Is it possible for these pollen grains to fertilize the egg cells? is it possible for seeds to develop in this flower?

1. Egge cells are fertilized. Seeds will develop.
2. Egg cells are fertilised. NO seeds will develop
3. NO egg cells are fertilised. Seeds will develop
4. NO egg cells are fertilised. NO seeds will develop

Seed dispersal is NOT happening by

1. wind
2. the hair/fur of animals
3. when bees are collecting nectar
4. by bursting/ "exploding" fruits
