Define plant meristem cells?
Plant meristem cells are differentiated cells that can divide definitely and give rise to one type of differentiated cells.
Plant meristem cells are undifferentiated cells that can divide indefinitely and give rise to many types of differentiated cells.
Choose the correct answers:
List the types of apical meristems.
Ground Meristem = ground tissue
Xylem meristem= phlome tissue
Protoderm. Meristem= epidermal tissue
Pro cambium = vascular cambium tissue

Describe the epidermal tissues in plants
They form the outer protective covering of a plant
They form the inner protective covering of a plant
Epidermis contains closely packed epidermal cells.
Epidermis contains closely packed cambium cells.
Why does the walls of epidermis are covered in waxy cuticules?
To minimize water loss and to protect it from bacteria and other species that might cause diseases
To maximize water loss and to expose it to bacterias and other species that might cause diseases
What is the importance of root hairs in root epidermal tissues?
To Increase surface area of root for water and mineral absorption and anchor the plant.
To Decrease surface area of root for water and mineral absorption and worsen the plant.
What is the role of trichomes in epidermal tissue
To expose the plant to the sun, moisture loss,and Discourage herbivory
To protect the plant to the sun, moisture loss,and Discourage herbivory
Describe parenchyma cells
Least specialized and most abundant cells
Found in specific organs
Contains chloroplast and performs photosynthesis
Contains vitamins and nutrients
Can divide and give rise to more specialized cells
Describe Collenchyma cells
Supports immature parts of a plant
Has thick secondary walls
Forms bundles underneath epidermis
Has thick primary walls
Forms bundles above epiderms
True or false
Scelerenchyma has thick secondary walls that are impregnated with liginin
True
False
True or false
sclerenchyma cells supports immature parts of a plant
True
False
True or false
In scelernchyma cells most are nonliving at maturity
True
False
Two types of sclerenchyma cells:
Fibers
Annual
Vascular
Sclereids
True or false
Sclereids are long and they are grouped in bundles
True
False
True or false
Fibers are short and more varied
True
False
Describe xylem as vascular tissue in plants?
It transports water and minerals from roots to leaves
It transports sucrose and other organic compounds
Xylem is specialized parenchyma cells.
What are the 2 types of Cells that can conduct water in xylem
Cambium
tracheids
Monocot
Vessel elements
Explain the structure and function of phloem in vascular tissue?
Phloem transports sucrose and other organic compounds.
Conducting cells of phloem are specialized parenchyma cells.
Sieve-tube members function as conducting cells.
Each sieve-tube member has a companion cell which is involved in transport function.
