Q

What are the functions of the apical and lateral meristem?

A

apical meristem - found on growing plant tips; makes plants grow taller
lateral meristem - found on lengths of roots and stems; makes plants grow thicker a.k.a VASCULAR CAMBIUM and CORK CAMBIUM

Q

What are the functions of the simple and complex tissues?

A

Simple tissues - composed of only one type of cell
Complex tissues - composed of more than one type of cell that function together as one unit.

Q

What is the function of the Parenchyma?

A

Parenchyma -

living tissues that are thin-walled, with cytoplasm. Performs most of the metabolic functions; provides support; stores various organic products

16
Q

What is the function of the Collenchyma?

A

Collenchyma -

living tissues with cells that have thick primary walls; provides support to the young parts of the plant shoots; flexible support

17
Q

What is the function of the Sclerenchyma?

A

sclerenchyma -

dead cells that have thick walls containing lignin - enhances cell wall rigidity (strength); provides support; withstand strains;protects inner cells from damage

18
Q

What are the two types of complex tissues?

A

i. Xylem
ii. Phloem

19
Q

What are the functions of the Xylem and Phloem?

A

Xylem - conducting tissues*, transports water and minerals from the roots to the leaves; mostly dead cells

Phloem - conducting tissues; transports food from the leaves to other parts of the plant, mostly living cells

*group of cells that are responsible for transporting food materials and water to different parts of plants

20
Q

What are the 4 types of animal tissues?

A

A. Epithelial Tissues
B. Connective Tissues
C. Muscle Tissues
D. Nerve Tissue

21
Q

What are epithelial tissues?

A

they are made of thin cells that cover the body, organs blood vessels and body cavities

22
Q

How are epithelial tissues classified?

A

they are based on:

  1. number of layers (simple and stratified)
  2. shape of individual cells (squamous, cuboidal, columnar)
23
Q

What are Connective Tissues?

A

They are cells that vary widely in form and function but mostly support the body and form the structure

24
Q

What are the Types of Connective Tissues?

A

a. loose/areolar - holds organs in place

b. fibrous - a.k.a. dense connective tissue; made of collagen and resistant to stretching and strength

c.adipose - composed of fat storage cells; facilitates energy storage and provides insulation

d. bone - hardest connective tissues; provides protection, strength, and support.

e. cartilage - composed of collagen fibers; reduced friction between bones; provides support, structure, and strength.

f. Blood - a.k.a. Fluid connective tissue; transports oxygen and nutrients

25
Q

What are Muscle Tissues?

A

made of cells that possess contractile filaments that change the size of the cell; facilitates movement

26
Q

What are the types of Muscle Tissues?

A

a. Skeletal
b. Smooth
c. Cardiac

27
Q

What are Skeletal Muscle tissues?

A

Skeletal - striated (banded) and attached to bones by the tendons; cells with many nuclei; responsible for voluntary movement

28
Q

What are Smooth Muscle Tissues?

A

these tissues lack striations; in the walls of internal organs; involuntary movements

29
Q

What are Cardiac Muscle Tissues?

A

striated; cells connected by intercalated* disks; contractions of the heart

*something between layers

30
Q

What are Nerve tissues?

A

these are tissues responsible for the transmission and receipt of signals that provide information

31
Q

What are Nerve tissues made of?

A

neurons and neuroglia
