18
Q

They store mostly water and salts that cannot
be preserved for microscopy;

A

VACUOLE

19
Q

Sometimes contain visible crystals, starch,
protein bodies, and various types of granules
or fibrous materials in addition to water and
salts.

A

VACUOLE

20
Q

VACUOLE FUNCTION:

A

storage of both nutrient reserves and waste products

21
Q

It is the semi-fluid substance of a cell that is present
within the cellular membrane and surrounds the
nuclear membrane.

A

CYTOPLASM

22
Q

The nonnuclear content of the protoplasm

A

CYTOPLASM

23
Q

All the
cellular contents in a prokaryote organisms are
contained within cell’s

A

CYTOPLASM

24
Q

In ________ organisms, the nucleus of the cell is
separated from the cytoplasm.

A

eukaryote

25
Q
  • It provides mechanical support to the internal structures.
  • It is the medium for suspension for the internal organelles of
    the cell.
  • It maintains the shape and consistency of the cell.
  • It also stores many chemicals that are vital for life.
  • Important metabolic reactions like the glycolysis and
    synthesis of proteins takes place in the cytoplasm.
A

CYTOPLASM

26
Q

takes place where there is movements of the cytoplasm
around the vacuoles.

A

cytoplasmic streaming

27
Q

is a rod-shaped organelle that is functions as the
cells’ power generator that converts oxygen and
nutrients into adenosine triphosphate or ATP.

A

MITOCHONDRION

28
Q

is a molecule that can be easily used by the
plants as a source of chemical energy.

A

ATP

29
Q

Main sources of energy for each cell

A

MITOCHONDRION

30
Q

The process for converting raw nutrient materials
into usable energy is known as

A

cellular respiration

31
Q
  • large sheets of folding that provides room for large
    numbers of enzymes.
A

Cristae

32
Q

It gives shape and a little rigidity to the mitochondrion
it is rather freely permeable

A

Outer mitochondrial membrane

33
Q

forms the cristae, and is selectively permeable and has
numerous pumps and channels.

A

Inner mitochondrial membrane

34
Q

are group of dynamic organelles able to perform many functions.

A

PLASTIDS

35
Q

PLASTIDS
TYPES:

A
  • Proplastids
  • Chloropasts
  • Amyloplasts
  • Chromoplasts
  • Leucoplasts
  • Etioplasts
36
Q

small and undifferentiated plastids, are plastids of
young, rapidly dividing cells.

A

Proplastids

37
Q

it is green owing to the presence of the
photosynthetic pigment chlorophyll, thus carry out
photosynthesis, are plastids that are exposed to
light.

A

Chloroplasts

38
Q

store starch; considered to be leucoplasts.

A

Amyloplasts

39
Q

develop into amyloplasts which
accumulate sugar and store it as starch for months

A

Proplastids

40
Q

contain abundant colored lipids; in flowers and
fruits

A

Chromoplasts

41
Q

colorless plastids, synthesize lipids and other
materials

A

Leucoplasts

42
Q

A specific stage in the transformation of proplastids
to chloroplasts; occur when tissues are grown
without light

A

Etioplasts
