Lesson 5
- AnythingPLANT ORGANS the
above : ROOTS
root system
(consists of root) is called shoots.
SHOOT SYSTEM
- Shoot system consists of stems. Also
flowers and fruits if the plant is an
angiosperm.
Organs
- Group of tissues that act together to
perform specific function
- Vascular tissue - xylem and phloem
- Ground tissue - parenchyma, Functions:
collenchyma, and sclerenchyma - Photosynthesis (leaves)
- Epidermis and periderm - Structural support (stem)
- Transport substances (vascular
tissues are present in all systems)
- Produces flowers for sexual
reproduction (angiosperm)
ROOT SYSTEM
- Usually below ground
- Dermal tissue

- Heterotropic (can’t create own - Root hairs are only present on certain
nutrients) parts of the root.
- Roots get nutrients from the product - Root hairs are to further maximize the
of photosynthesis (glucose) that is
transported by the vascular part,
phloem, all throughout the plant,
especially on the roots.
Functions:
- Anchorage
- Absorption (absorbs water and
minerals needed for photosynthesis)
- Corn roots need a lot of
water as they need 2L of water
a day
- Conduction (roots defuse water and
will distributed all throughout the
plant)
- Storage (stores a lot of energy
- There are non-absorptive regions in
the roots. And these regions produce
other roots.
- Producing more roots is a means for
them to locate water and minerals in
the soil.
- Primary root produces secondary root,
while secondary root produces tertiary
root.
