Biology 3

Why is water important to plants?
Support, Use in Photosynthesis, Transport of Minerals
1 of 9
How does water support the structure of the plant?
Vacuoles push against the cell walls keeping them turgid
2 of 9
How do plants uptake water?
Areas of high water concentration to areas of low water concentration through a partially permeable membrane (Osmosis)
3 of 9
How do plants uptake mineral salts?
From areas of low to high concentration (Active Transport). Requires energy which is released during respiration
4 of 9
What is significant about root hair cells?
Increased surface area allows for more absorption
5 of 9
What are the functions of Phloem?
Carry sugar from photosynthetic areas of plant to less photosynthetic areas
6 of 9
What is the sugar used for?
Converted to starch for storage and in respiration
7 of 9
Name 2 functions of Xylem
Support, Transport of Minerals, Transport of Water
8 of 9
What is the function of stomata?
Open and close to regulate transpiration
