Plant transport and osmosis 🚗🍀 Flashcards
Why what process does water enter the root hairs
Osmosis
Two Irish scientists who is covered the upward movement of water in plants
Henry Dixon,
John Joly
Describe in detail the upward movement of water in plant
Water molecules stick together,
Water molecules stick to xylem walls,
Evaporation,
Tension
Three ways plants use to control transpiration
Waxy cuticle,
Action of stomata,
Location of stomata
Three structural differences between xylem and phloem
Xylem has lignin phloem does not,
Xylem is a continuous tube phloem is not,
Phloem has nuclei Xylem does not
What zone of a plant root is water absorbed through the soil
Differentiation
Process by which water is absorbed from the soil
Osmosis
Tissue that transports water in roots
Xylem
Three ways that xylem is adapted to transporting water
Hollow,
Contains lignin,
Continuous tube
Vascular tissue by which the products of photosynthesis are transported in plants
Phloem
Three structural features of phloem
Companion cells,
Sieve plates,
Cytoplasm pushed to edges
Cells that control opening and closing of stomata
Guard cells
Advantage to plants having mot of their stomata on the underside of the leaves
Reduces water loss by evaporation
Disadvantage to plants of a high rate of transpiration
Wilting
What do plants do in response to wilting
Close stomata
Explain term vegetative propagation
Plant asexual reproduction
Three features of vegetative propagation
One parent,
No variation,
No gametes/seeds
