B2 : Transport system in plants

Question 1

How do plants make glucose and what is it used for

Answer 1

Photosynthesis, it is used to combine with nitrates to from amino acids which makes proteins for gowth and repair

Question 2

Phloem

Answer 2

The phloem transports glucose and other sugars made in photosynthesis to the rest of the plant like the stems and roots

Question 3

Translocation

Answer 3

Movement of sugars around the rest of the plant.

Question 4

Phloem

Answer 4

A transport system that transports glucose and other sugars to the rest of the plant. it is made of of living tissues with elongated cells with pores at the end so sugar solution can move through.

Question 5

Aphids

Answer 5

Creatures scientists use to determine the function of the phloem. The stylet of the aphid is inserted into the phloem to feed. The aphids body is then removed leaving the stylet in the phloem, sap containing sugars flow out of the phloem through the stylet

Question 6

Xylem

Answer 6

A transport system that carries water and mineral ions from soil to the stems in leaves. Mature xylem cells are dead . They are made of hollow tubes strengthened by lignin.

Question 7

Why are transport systems needed in plants

Answer 7

To produce glucose and water
Glucose is needed all over the plant for use in respiration and growth. Water is needed for photosynthesis and to hold the plant upright.

Question 8

Xylem in woody plants

Answer 8

In woody plants like trees, the bulk of the bark is made up of xylem with the phloem found in a ring just underneath the bark. Young trees have thin bark which animals like deer eat away preventing translocation and resulting in the death of the tree
