Science(Structure and transport in flowering plants)

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
