7
The functions of ground tissue include photosynthesis, storage, and support
disagree
no
agree
l don't know
8
How is a plant cell similar animal cell ?
the vacuole in plant cell is larger than in animal cell
both have ribosome , nucleus ,mitochondria and vacuole
in animal smaller vacuole , lack cell wall and chloroplast
they all have nucleus ,cytoplasm and ribosomes
9
Meristematic tissues responsible for increase in diameter
Lateral meristems
apical meristem
cork cambium
vascular cambium
10
what is the location of parenchyma ?
everywhere
in growing regions

12
what is the study of cells and tissues ?
human biology .
histology
tissue
biochemistry
13
hair like projections that prevent evaporation in plant leaves is called ?.
cambium
xylem
trichomes
root hair
14
How is a plant cell different from animal cell ?
they all have nucleus ,cytoplasm and ribosomes
in animal smaller vacuole , lack cell wall and chloroplast
the vacuole in plant cell is larger than in animal cell
both have ribosome , nucleus ,mitochondria and vacuole
15
list types of sclerenchyma
vessel element , tracheid ,fiber and parenchy
companion cells , sieve tube and sieve plate
fiber and sclerid
parenchyma ,collenchyma and sclerechyma
16
what is the function of the part labelled 10?
internal circulation of gases (CO2 and O2)
protection against water lost
photosynthesis
closing and opening of stoma
17
what kind of cells are found in parenchyma?
storage and photosynthesis
very thick and rigid and die at maturity,
These spherical cells have thin, flexible cell walls
Cells are long cells with unevenly thickened cell walls
18
Meristematic tissues found at or near the tips of roots and stems
Lateral meristems
cork cambium
vascular cambium
apical meristem
19
gritty texture of pears is
cork cambium
vascular cambium and cork cambium
apical meristem
sclerid
20
what kind of cells are found in sclerenchyma ?
These spherical cells have thin, flexible cell walls
storage and photosynthesis
Cells are long cells with unevenly thickened cell walls
very thick and rigid and die at maturity,
21
what is the function of a stoma ?
control movement of gases and water .
These cells cover the surface of stems and roots.
xylem and phloem cells in the stems and roots
This meristem adds cells that lengthen
22
why is cell 9 has more green structures than the other cells ?
because it is associated with photosynthesis
because it is big in size
because of internal circulation of gases (CO2 and O2)
it helps to closing and opening of stoma
23
The phloem is composed of the following
parenchyma , fiber and collenchyma
parenchyma ,collenchyma and sclerechyma
vessel element , tracheid ,fiber and parenchy
companion cells , sieve tube and sieve plate
24
The cork cambium produces
This meristem adds cells that lengthen
These cells cover the surface of stems and roots.
produces cells with tough cell walls.
xylem and phloem cells in the stems and roots
25
what is the location of sclerenchyma ?
in growing regions
everywhere
in bark of a tree
outside tissues of plants
26
