Q

Forms the body and also helps the bones in body movement

A

Muscle or muscular tissue

24
Q

different kinds of muscular tissues:

A
  1. skeletal
  2. smooth
  3. cardiac
25
Q

Muscles can be grouped into two:

A

voluntary and involuntary

26
Q

are muscles that can be controlled by the nervous system

A

voluntary muscles

skeletal muscles attached to the bones are voluntary muscles. They only move at our will.

27
Q

muscles that are beyond the control of the nervous system

A

involuntary muscles

e.g. muscles of the digestive tube and the heart

28
Q

type of muscular tissues

are made up of very long, cylindrical, multi-nucleated cells capable of quick and forceful contractions that are usually voluntary

A

Skeletal muscles

interactions of the thin and thick fillaments make it possible for them to slide through each other during contraction

29
Q

type of muscular tissues

  • are composed of elongated branched individual cells that are configured parallel to each other
  • capable of involuntary, vigorous, and rhythmic contractions
A

cardiac muscles

30
Q

tyoe of muscular tissues

  • are collections of cells that do not show cross-striations
  • largest at their midpoints and taper toward their ends
  • contraction process is slow and involuntary
A

smooth muscle

e.g. digestive tube

31
Q

comprised of cells that are specialized for the reception and conduction of impulses

A

nervous tissues

usually found in the brain & spinal cord except for cytoplasmic extensions like axons

32
Q

individual cells of the brain and the spinal cord

A

neurons or nerve cells

33
Q

types of neurons according to functions:

A
  1. sensory
  2. motor
  3. interneurons
34
Q

carry information obtained from the interior of the body and the environment to the CNS (central nervous system)

A

sensory neurons

35
Q

carry impulses from the CNS to the effector organs commanded by these centers

A

motor neurons

36
Q

are found only in the CNS, connect one neuron to another.

A

Interneurons

37
Q

Plant tissues can be classified based on origin:

A
  1. meristematic or embryonic
  2. non-merismatic or permanent
38
Q
  • these tissues are mostly located at the tips of roots and shoots of plants – where cells actively divide
  • they are responsible for the production of more cells
A

merismatic or embryonic tissiue

new cells formed are typically small, each with a proportionately large nucleus at the center and tiny vacuoles or no vacuoles at all

39
Q

found at the tips of shoots and roots which increase in length and produce new cells

A

apical meristems

40
Q

found at the vicinity of nodes which occurs at intervals along stems

A

intercalary meristems

they also increase the length of stems

41
Q

increase the girth or diameter of plants. they are also found along the sides of some roots and stems.

A

lateral meristems

42
Q

these are tissues formerly derived from meristems but have already assumed various shapes and sizes related to their specific functions as they develop and mature.

A

non-meristematic or permanent tissues

usuaally non-dividing with few exceptions

43
Q

kinds of non-meristematic tissues:

A
  1. surface
  2. fundamental
  3. vascular
44
Q

serve as the outermost covering in plants

A

surface tissues

45
Q

two types of surface tissues:

A
  1. epidermis
  2. periderm
46
Q
  • the outermost layer of cells of all young plant organs
  • one-celled, thick, and may have several layers in some.
A

epidermis

47
Q
  • functions for added protection and usually found in mature plants
  • consists of sevral layers of dead cells impregnated with suberin or waxy substance when mature found in bark of trees.
A

periderm

48
Q

are designed to give support and strength to the plant

A

fundamental tissues

49
Q

the most abundant of all the cell types and found in almost major parts of higher plants

A

parenchyma

  • cells are more or less spherical in shape when newly produced
  • they push against each other when they mature and their thin pliable cells are flattened at points of contact
50
Q

composed of uneven thick-walled cells. they often occur just beneath the epidermis.

A

collenchyma

51
Q
  • characterized by cells with thick and tough cell wall.
  • these are normally impreganated with lignin
  • dead at maturity and function for support
A

sclerenchyma

commonly found in pears and chicos (also known as “stone cells”)

52
Q

are involved in the transport of substances in the body of the plants

A

vascular tissues

53
Q

types of vascular tissues:

A
  1. xylem
  2. phloem
54
Q

functions for conducting water and
minerals in the plant upward

A

xylem

55
Q

which function for translocating food materials to all the growing parts of the plants and roots

A

phloem

56
Q

+

sample tissues or cells from plants are isolated and grown aritificially in specific culture media

A

plant tissue culture (micropropagation)
