Question | Answer |
Name a type of flowering plant | Oak,ash or chestnut tree |
What is the structure of a typical flowering plant? | A root system and a shoot system |
Where is the root system located? | Below the ground |
Where is the shoot system located? | Above the ground |
What are the functions of the roots? | Anchor and support the plant in soil. Take in or absorb water and minerals |
What type of minerals do the roots absorb? | Nitrogen,phosphorus and potassium |
What does the shoot system consist of? | Stems,leaves and flowers |
What are the functions of the stem? | To support or hold up the leaves and flowers.To transport water and minerals from the roots to the leaves. (some stems store food, e.g potato) |
What are the functions of the leaves? | Make food through photosynthesis. Allow gasses to pass in and out. Allow water vapour to pass in and out of the plant. ( some leaves store food e.g cabbage and lettuce) |
What gas do leaves allow to pass in? | Carbon dioxide |
What gas do leaves allow to pass out? | Oxygen |
What is transpiration? | The loss of water vapour from a plant |
How would a person show the path of water through a plant? | Put water + food dye in a beaker.Put a stalk of celery with leaves attached into the beaker.Leave it in a bright warm room for a few days,remove the celery + rinse off the colored water.Cut sections through the stalk.Note the pattern of the colored water |
Following the last question and answer. A person did show the path of water through a plant,what was their result? | The coloured water was seen as lines of colour in the stalk and leaves |
How would one show that water is taken in by the roots and passes up and out of a plant? | Put a plant into a testube.Add water enough to cover the roots.Add a layer of seeding oil.Put a masking tape to mark the top level of the water. Leave in a warm room for a week. The water level should have gone down |
Why was a layer of seeding oil added to the experiment? | The oil prevented the water from evaporating |
How would a person show that water evaporates from the surface of a leaf by transpiration? | Water a plant in a pot.Cover it with a transparent plastic bag and tie the end of it. Leave it in a bright warm room for a few hours.Drops of liquid will form inside the plastic bag |
What is xylem? | A tissue that transports water |
What is phloem? | A tissue that transports food |
