Stem
Leaf
Flower

Question 14

Root

Answer 14

Absorbs water and minerals, anchors the plant and stores food

Question 15

Stem

Answer 15

Holds leaves up and transport between leaves and roots, photosynthesis and stores food

Question 16

Leaf

Answer 16

Photosynthesis, protection

Question 17

Flower

Answer 17

Sexual reproduction

Question 18

Primary tissues

Answer 18

Vascular Cambium
Primary Xylem
Primary phloem
Pith
Fibres
Cortex

Question 19

Secondary tissues

Answer 19

Mature from cambium
Cambium cells that remain grow and divide
New cells produced turn into secondary tissues
