🚨Plant structure Flashcards
Give one function of vascular tissue present in plants
Transport and support
Name two types of vascular tissue in plants
Xylem and phloem
Give one disadvantage of self pollination
Less genetic variation,
Or,
Offspring will be more susceptible to disease
Give one way seedless fruits may develop
Spray with growth regulators/auxins
Outline how a à scientists uses à coverslip
Lowered slowly at an angle
Explain why a coverslip is uses
Prevents specimen from drying out
In which zone is water absorbed from the soil
Zone of differentiation
Name proves through which water is absorbed from the soil
Osmosis/ active transport
Name tissue that transports water in roots
Xylem
How is xylem adapted to transporting water
Hollow,
Has lignin
Describe mechanism by which water moves through the tissue to the leaves in a plant
Water molecules stick together,
Forming continuous column,
Water molecules sticks to side of xylem,
Root pressure pushes water upwards
What is turgor pressure in plants
Pressure of cell contents against the cell wall
How do plant cells remain turgid for long periods of time
By taking in as much water as they lose
What happens to a plant if many of its cells lose turgidy
Lose rigidly and wilt
Name a part of the body where active transport happens.
Location and active transport material involved
Nephron,
Water and salts
Name the structures in stems, equivalent to stomata is leaves, that are involved in gaseous exchange
Lenticels
Two compounds that leaves the plant through lenticels (in the stem)
Water and carbon dioxide
Would you expect the daughter plant formed from vegetative propagation to be haploid or diploid and why?
Diploid,
Product of mitosis that is genetically identical to the parent
Two methods other than runners, and not involving seeds that horticulturists use to produce plants
Cuttings, micro-propagation
Example of monocotyledonous plant
How are the veins arranged in the leaves of monocots
Parallel
How does the vein arrangement in the leaves of dicot plants differ from that in monocots
Net or branched
