BIO203 EXAM UTM QUESTIONS &
ANSWERS (RATED A+)
T/F: vascular plants have modular/reiterative development - ANSWERT
What are the basic plant organs? - ANSWERroots, stems, leaves
Chromoplasts function and location - ANSWER-Chromoplasts often develop from
chloroplasts, but may also form from proplastids & amyloplasts .
-Often found in flowers, fruits, senescing leaves and certain roots.
leucoplast function - ANSWERstore pigments, proteins, lipids, starch
Amyoplast function: - ANSWER-Store fixed carbon reserves as starch. Starch
granules. Found in roots (detection of gravity?) & storage tissues (e.g. cotyledons,
endosperm, & tubers.
What are the major non reproductive simple primary plant tissues? -
ANSWERParenchyma, collenchyma, sclerenchyma, root endodermis, pericycle
What are the major non reproductive specialized cells? - ANSWER-Parenchyma
cells(in parenchyma)
-collenchyma cells(in collenchyma)
-sclerieds&fibers(in sclerenchyma)
-endodermal cells(in root endodermis)
-pericycle cells(in pericycle)
Fruit typically develops from... - ANSWERthe ovary/ovaries of flower(s)
Simple, fleshy fruits include... - ANSWERTrue berry, hesperidium, false berry, pepo,
drupe
Accessory fruits include... - ANSWERPomes, strawberry, fig, blackberry
Aggregate fruits include... - ANSWERBlackberry, raspberry
Multiple fruits include... - ANSWERPineapple, mulberry, fig
,Dry Simple Fruits are formed from.... - ANSWER• Formed from a simple or
compound ovary with only one pistil, where the pericarp is dry at maturity.
Dehiscent fruits - ANSWERsplit open when mature
indehiscent fruits - ANSWERdo not split at maturity
tetrochromatic animals - ANSWERbirds,some reptiles and fish too
bichromatic animals - ANSWEREutherian mammals
What are the differences between parenchyma and collenchyma tissues? -
ANSWER-Parenchyma has a nucleus, 1+ vacuoles and cytoplasm
-Collenchyma is alive at maturity
- Parenchyma has thin primary cell wall and collenchyma has thick primary cell wall
- Collechyma is used for support&protection whereas parenchyma is used in
photosynthesis, storage, pith, and transport
-Parenchyma stains pink w TBO and collenchyma stains dark pink/purple
What are the similarities between parenchyma and collenchyma tissues? -
ANSWERboth primary cell walls are unlignified
What is the difference between sclerenchyma and collenchyma? -
ANSWERSclerenchyma are dead at maturity
T/F: Sclerenchyma have thickened primary and secondary cell walls - ANSWERT
What colour do the cell walls of sclerenchyma tissues stain? - ANSWERBlue/Blue-
Green
What is the function of sclerenchyma tissues? - ANSWERSupport& protection from
micro-organisms
What are the complex primary plant tissues? - ANSWERLeaf mesophyll, xylem,
phloem, epidermis, secretory tissues
What are the complex primary specialized plant cells? - ANSWER-Spongy
mesophyll cells& palisade mesophyll cells(in leaf mesophyll)
-Fibers, parenchyma cells, trachieds, vessel elements, transfer cells(in xylem)
-Fibers, parenchyma cells, sclerids, sieve tube members, companion cells, sieve
cells alumbuminous cells(in phloem)
-shoot& root epidermal cells, trichomes, cells associated w pores, guard cells
subsidiary cells(in epidermis)
, -transfer cells, seceratory cells(in seceratory tissues)
What are the complex secondary specialized plant cells? - ANSWERSecondly
xylem, secondary phloem, periderm
What are the complex secondary plant tissues? - ANSWER-Fibers, parenchyma
cells, trachieds, vessel members(in secondary xylem)
-Fibers, parenchyma cells, sclerids, sieve tube members, companion cells, sieve
cells alumbuminous cells(in secondary phloem)
-cork cells, cork cambium, parenchyma cells(in periderm)
Xylem function: - ANSWERTransports water and dissolved minerals from the root up
to all the other parts of the plant
T/F xylem cells are often alive initially but are often dead at maturity - ANSWERT
Phloem function: - ANSWER-Transports fixed carbon i.e. food nutrients such as
glucose from the leaves to other parts of the plant
-long distance signalling molecules
Epidermis function: - ANSWER-protective of abiotic and biotic factors
-gas exchange& transpiration(in the shoot)
-secretory
-structural
Growth and development are resultant of... - ANSWERelongation&expansion
Apical meristem function: - ANSWER-responsible for elongation growth
-elaborate the adult plant
-Primary SAM & RAM
Lateral meristem function: - ANSWER-Secondary growth
-adds thickness to woody plants
Intercalary meristem function: - ANSWER-growth of cut grass
-in monocots
-primary meristem
