A typical plant body consists of _____and ______

roots ; shoots

Where do plants draw their resources from?

Roots and shoots

Root System

Anchors plants in soil

Absorbs/transports minerals/H2O

Stores food

Roots hairs _____ absorptive surface


Shoot System

Obtains CO2 & light from air

Stem(nodes/internodes) support leaves/flowers

Leaves are ______ organs; flowers are _______ organs (terminal/axillary buds)

Photosynthetic; reproductive

Apical dominance

Is an evolutionary adaptation the increase the plant's exposure to light

Many plants have modified ______, _______, and _______

Roots , stems, and leaves

Function of modified roots

Store sugar

Function of modified stems

Stolons enables a plant to reproduce asexually

Rhizomes store food and can form new plants

Tubers are structures specialize for storage

Function of modified leaves

Store food or water

Fn in protection of plant

Aid in climbing (tendrils)

The three tissue systems that make up the plant body

Dermal, vascular, and ground

Dermal tissue system

Forms outer protective covering of the plant; epidermis and cuticle

Vascular tissue system

Contains xylem and phone

Provides long-distance transport/support

Ground tissue system

Most of the bulk of the petals



Pith is _____ to vascular tissue; cortex is ______ to vascular tissue

Internal; external

Arrangement of tissue systems in root

Vascular cylinder is in center

Ground tissue system consists entirely of cortex

Vascular cylinder structure

Xylem radiates out

Phloem fills in space

Arrangement of tissue in stem

Vascular tissue in vascular bundles

-Dicot, arranged in a ring

-Monocot, scattered throughout ground tissue

Ground tissue

-Dicot, has both cortex and pith region

-Monocot, not divided into regions

Arrangement of tissue in leaf

Epidermis interrupted by stomata flanked by guard cells

Mesophyll ground tissue sandwiched between lower and upper epidermis

Vascular system made up of network veins

Plant cells 3 unique structures/functions

Chloroplasts, the sites of photosynthesis

Central vacuole, containing fluid

Cell wall, surrounds the plasma membrane

What are the five major types of cells?

Parenchyma, collenchyma, sclerenchyma, fibers, sclereids


Perform most of the plants metabolic functions


Provides support


Form a rigid skeleton that supports the plant the main component of wood


Long cells arranged in bundles


Shorter, have very hard secondary walls

Primary growth _______ a plant to grow in length; primary growth ______ behind the root tip in 3 zones

Enables; occurs

Apical meristems

Are unspecialized cells that continue to give rise to new cells

Location of apical meristems

Tips of rod and terminal/axillary buds of shoots

Structures of apical meristem

Covered by protective root cap that is sloughed off during growth

What are the 3 zones where primary growth occurs?

Zone of cell division, zone of elongation, zone of maturation

Secondary growth ______ the girth of woody plants


Secondary growth is produced by _______

Lateral meristems

Lateral meristems

Two cylinders of dividing cells, vascular cambium and Cork cambium
