Root system or shoot system
a.Leaf –shoot system
b.Stem- shoot system
c.Roots- root system
PLANT TISSUE
 The vascular system of a plant is most like the circulatory system of the
animal in that is transports nutrients and waste throughout the plant.
 The Xylem carries Water-(W-XY-Z)
 The Phloem carries Food- (ph-f)
 You can think the dermal tissue of a plant like the skin (dermis &
epidermis) of a human. It is a thin layer that covers the inner tissue of a
plant
PLANT HOMEOSTASIS
 Transpiration is the loss of water through the stomata in a leaf
 Guard cells control the opening and closing of stomata. Usually
associated with gas exchange.
 When stomata are open, water is lost , like sweating this cools the
plant down
 In extremely dry weather stomata will close to preserve water.
PLANT RESPONSES
 Phototropism causes the cells on the dark
side of a plant to elongate and bend toward
the light.
 Thigmotropism is the plants response to
touch. Such as a vine
 Geotropism/gravitropism is the plant
growing towards or away from the earth as a
result of gravity. Root systems grow with
the force of gravity (positive tropism), shoot
systems grow opposite the force of gravity
(negative tropism)
PLANT REPRODUCTION
 Gymnosperms and Angiosperms both reproduce sexually
 Gymnosperms have cones containing male gametes and female cones
with the female gamete
 Angiosperms have flowers with male and female structures
(pistil and stamen)
 Both depend on wind, water, or
pollinators to spread the gametes to
other plants for pollination
 Ferns & Moss reproduce by releasing
millions of spores. This is asexual
reproduction
This feedback mechanism reacts to
changes in the body and provides
necessary means to return the body to
normal.
