what are the roles of the leaf ?
1. The leaf produces food by photosynthesis 2. Takes in CO2 and releases O2 3. Allows water to exit the plant
What are the roles of the roots?
1. Absorption of water 2. Anchoring the plant body to the ground and protecting it 3. Storage of food and nutrients 4. Translocating water and minerals to the
What are the three processes that allow water to move up a plant?
1. Transpiration, 2. Capillary action, 3. and Osmosis.
What is transpiration and where does it take place?
It is the evaporation of water from the surface of the plant mainly from the leaves,and more water particles move up within the plant to take their place>
What is osmosis ?
When the concentration of water in the soil is greater than the concentration of water in the roots of the plant, water moves into the root cells.
What is a seed plant?
A plant that makes a seed.
What are the roles of the stem?
● Provide a pathway for the movement of water and food
● Support the leaves and reproductive structures
How are flowers and cones different when it comes to reproduction?
flowers have both the female (the Ovary) and male (Pollen) parts while cones are either male or female (you need two cones for a seed)
What do seeds contain?
1. The Embryo that will grow into a new plant 2. The stored food for the embryo
What is capillary action ?
The movement of liquid along a surface of a solid caused by the attraction of molecules of the liquid to the molecules of the solid.
Where does the capillary action happen?
Water travels from the roots to the leaves through tiny tubes in the roots and stems.
Where does osmosis happen?
Water from the soil enters root cells by a process called Osmosis.
