Flashcards in Chapter 22- Transport, Nutrition And Food Storage In Flowering Plants Deck (15):
1

Flowering plants are autotrophic. What does this mean?

They make their own food
Photosynthesis

2

Uptake of water in plants

Water is need for photosynthesis
Plants get water form soil
Water enters plants by osmosis

3

Adaptions of root hairs for water intake

Root hairs and numerous
Root hairs are thin walled
Root hairs don't posses cuticles

4

Transport of water in plants

Water diffuse across ground tissue and into xylem

5

Adaptions of xylem for water transport

Thin, hollow, continuous tubes with narrow bore
Strengthened with lignin
Pits to allow sideways movement of water

6

What is root pressure?

Force that pushed water up the stem from the root

7

What is transpiration?

Loss of water from surface of a plant

8

What is the cuticle of a plant?

Controls use of transpiration

9

What is a stoma?

Tiny openings on surface of leaves and stems allowing water vapour to escape

10

Uptake of minerals into plant

Absorbed by plants form soil in the for of ions
Minerals enter root through root hairs by diffusion

11

Transport of minerals through plant

Once in root, minerals pass across ground tissue to xylem

12

Uptake of carbon dioxide by plant

Needed for photosynthesis
Get it from respiration within cells or by diffusion from air through stoma

13

Transport of carbon dioxide

Diffuses through air spaces in leaf and from cell to cell
Used to make food

14

Transport of products of photosynthesis

Glucose and oxygen
Glucose stored as starch
Or transported in for of sucrose

15

Who founded cohesion-tension model?

Dixon and Joly
