Adaptations for transport: PLANTS

Question 1

what is the word equation for photosynthesis?

Answer 1

carbon dioxide + Water ——-> Glucose + Oxygen

Question 2

what are the 2 transport systems in plants?

Answer 2

• Xylem
• Phloem

Question 3

what does xylem transport?

Answer 3

water + mineral ions
- photosynthetic cells in the leaf need water and mineral ions which are available only in the soil
- transport from roots to leaves (transported upwards in hollow tubes)
- dead cells

Question 4

what does phloem transport?

Answer 4

photosynthates (the glucose produced during photosynthesis is used to make amino acids)

• moves from leaves to other organs of the plant (eg. roots and flowers)
• bi-directional movement

Question 5

Mineral ions are _______ __________ from the soil into the root hair cells. this lowers the ______ __________ inside the root hair cell so water enters by _____.

Answer 5

-Actively transported
- Water Potential
-Osmosis

Question 6

name the 3 pathways used to transport minerals and ions across the root.

Answer 6

• apoplast
• symplast
• vacuolar
