Applied Biology Plant Review

In plants, the main organs of photosynthesis are the (a) roots (b) leaves (c) trunk (d) stems

b

Most of the wood in a tree is made up of (a) cork cambium (b) phloem cells (c) bark cells (d) xylem cells

d

Stomata open and close due to water pressure changes in the (a) guard cells (b) sieve tube member (c) root hairs (d) cortex

a

The type of plant tissue that divides by mitosis is (a) meristematic (b) xylem (c) phloem (d) parenchyma

a

Nutrient needed by plants to ensure proper leaf growth and color (a) Water (b) potassium (c) calcium (d) nitrogen

d

The inner part of bark is made of (a) xylem (b) parenchyma (c) phloem (d) cuticle

c

The vascular bundles in monocot stems (a) are arranged in a ring (b) are scattered throughout (c) contain phloem only (d) contain xylem only

b

Plants take in almost all their water and nutrients through structures called (a) guard cells (b) vascular cylinders (c) root hairs (d) osmosis

c

The root apical meristem is protected by the (a) bud scales (b) cuticle (c) root cap (d) cortex  

c

Nonfunctional xylem in the center of a tree trunk is (a) summerwood (b) sapwood (c) heartwood (d) springwood

c

A primary root that grows longer and thicker is a (a) fibrous root (b) apical root (c) meristematic root (d) tap root

d

A meristematic tissue that increases the thickness of plant stems over time is the (a) vascular cambium (b) apical meristem (c) pericycle (d) epidermal meristem.

a

Tracheids are the most important type of cells in (a) vascular cylinders (b) veins (c) xylem (d) phloem

c

Heartwood is older, darker xylem that still functions slightly rapidly divides during growth season carries water to the leaves Stops transporting water completely

d

The spot where leaves attach

Node

Waxy covering on upper epidermis of leaf

Cuticle

Outer protective covering

Epidermis

The area that cell differentiation is completed

Zone of maturation

Cylinder containing the xylem and phloem

Vascular cylinder

Meristimatic region that produces xylem and phloem

Vascular Cambium

Protective layer on the tip of the root

Root cap

Area that contains the apical meristem of the root

Zone of cell division

. Branch off a root that increases surface area

Root hair

Final Question

Surrounding a vascular bundle

endodermis

Name two functions each for roots, stems, and leaves

What two types of wood make up the rings of a tree What two types of wood make up the rings of a tree? What cause each type?(

Spring wood—wide gaps due to rapid growth Late wood—narrow gaps due to mostly dormant cell growth.

What is the difference between a compound and a simple leaf

Simple leaf—one leaf from per petiole Compound leaf—multiple leaves per petiole

Draw the cross section of a tree trunk and label the following parts Draw the cross section of a tree trunk and label the following parts. Pith, Heartwood, Sapwood, Vascular Cambium and Bark
