Flashcards in Chapter 22- Transport, Nutrition And Food Storage In Flowering Plants Deck (15):
Flowering plants are autotrophic. What does this mean?
They make their own food
Uptake of water in plants
Water is need for photosynthesis
Plants get water form soil
Water enters plants by osmosis
Adaptions of root hairs for water intake
Root hairs and numerous
Root hairs are thin walled
Root hairs don't posses cuticles
Transport of water in plants
Water diffuse across ground tissue and into xylem
Adaptions of xylem for water transport
Thin, hollow, continuous tubes with narrow bore
Strengthened with lignin
Pits to allow sideways movement of water
What is root pressure?
Force that pushed water up the stem from the root
What is transpiration?
Loss of water from surface of a plant
What is the cuticle of a plant?
Controls use of transpiration
What is a stoma?
Tiny openings on surface of leaves and stems allowing water vapour to escape
Uptake of minerals into plant
Absorbed by plants form soil in the for of ions
Minerals enter root through root hairs by diffusion
Transport of minerals through plant
Once in root, minerals pass across ground tissue to xylem
Uptake of carbon dioxide by plant
Needed for photosynthesis
Get it from respiration within cells or by diffusion from air through stoma
Transport of carbon dioxide
Diffuses through air spaces in leaf and from cell to cell
Used to make food
Transport of products of photosynthesis
Glucose and oxygen
Glucose stored as starch
Or transported in for of sucrose
