A carpel usually has 3 parts. What are the names of these 3 parts?

What are pollen grains?

Various steps in the fertilization of a plant are listed below.
A The nucleus moves towards the ovary.
B The pollen tube grows out of the pollen grain.
C The tip of the pollen tube breaks open.
D The pollen tube grows through the style.
E The two nuclei fuse.
F The pollen grain lands on the stigma. What is the correct sequence of steps?

People with hay fever have an allergic reaction to pollen that is drifting in the air.
Does that pollen come from insect-pollinated flowers or wind-pollinated flowers? Explain your answer.

What characteristics of the male flowers of the
hazel tree show that they are
wind-pollinated flowers? Explain your answer.

A pollen grain from a flower lands on a flower of another plantof the same species.
Is this self-pollination or cross-pollination? Explain your answer.

The fertilized ............. goes on to form a  seed, which contains a ............... and an .................. that will later grow into a new plant. The ....................develops into a .............. to protect the .............

Roots do not only absorb water from the ground, they also have another important function. Name that function and explain how the shape of the roots is very important for this process.

Germination is a very important process for plants. Explain in detail what germination is and how it happens, make sure you use the correct biological words.

The plant absorbs sunlight through the palisade cells.

The plant absorbs water and nutrients through the roothair cells.

The plant transports water and nutrients up through the xylem vessels.

The plant transports sugars and nutrients down through the phloem vessels.

The plant absorbs carbon dioxide through the stomata cells.

The plant releases oxygen through the stomata cells.

Some of the sugars produced by photosynthesis are stored as starch in the roots. What is an example of this?

1. tomatoes
2. potatoes
3. beans
4. spinach

1. carbon dioxide concentration
2. light intensity

4. water levels

Some plants have variegated leaves, this means with white parts which contain no chlorophyll. How do you think a variegated geranium would grow compared to a similar sized geranium with all green leaves? Explain your answer using key words you have learned.

A piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. What process is explained in the text above?

2. runners
3. grafting
4. cloning

The gardener wants his test to be fair. Name 3 conditions which he should keep the same for all his tomato plants. (Keep in mind this experiment is outside!!)

To obtain the biggest mass of tomatoes, against which wall is it best to grow the tomato plants? Explain your choice..
