Roots Flashcards
the underground part of a plant which supports the shoot system
root system
is comprised of the primary root (main root) which branches into secondary root and tertiary roots
root system
types of root system
- taproot system
-fibrous root system - modified roots
generally found in dicotyledons, its made up of a central, large root that is called the
taproot system
functions of taproot system
- to absorb water and nutrients from the soil
- to provide stability to the plant by anchoring it into the ground
is made up of thin, stringy roots that all have about the same diameter. these roots branched several times and form a complex mat under the plant that binds to the upper soil layer
fibrous root system
can be found in monocots such as grasses
fibrous root system
function of fibrous root system
- absorption of plant nutrients and water from soil
which type of root system provides strong anchorage?
- taproot system. this system consists of a main, thick root that extends deep into the soil enhancing stability and support for the plant
what are the modified roots
- stilt roots / prop roots
- buttress roots
- fleshy and enlarged roots
- aerial epiphytic roots
- haustorial roots
- pneumatophores
a modified root that arise from around the base of the stem and help in the mechanical support
stilt roots/ prop roots
a modified roots that compressed and flattened plants like roots that grows out from the base of the trunk for additional support
buttress roots
a modified root that grow underground and are specially modified for storage of starch and water
fleshy and enlarged roots
a modified root that hang freely in the air and absorb moisture with the help of special sponge like tissue called velamen
aerial epiphytic roots
a modified root of a parasitic plant which penetrate host’s tissues and absorbs nutrients and water
haustorial roots
