Answers
1
The xylem and phloem are part of which plant system?
Vascular/Transport
No plant system
Response
Reproductive
2
What is the function of stems & trunks?
to collect water and minerals
to support the leaves and reproductive parts
to anchor the plant in its environment
to produce new offspring
3
Auxin, a plant hormone, causes cells on the shady side of a plant to elongate. The response is
geotropism
phototropism
transpiration
photosynthesis
4
The pistil is made up of..
#'s 2, 3 an 4
#'s 2 and 4
#'s 1 and 6
#'s 1,3 and 5
5
The style is part of which plant system?
support
response
transport
reproductive
6
What vascular tissue transports H2O & minerals from the roots to the stems & leaves of a plant?
cambium
xylem
rhizoid
phloem
7
Leaves are part of a plant's shoot system. The xylem tissue in leaves transports:
oxygen that regulates the rate of carbohydrate production
the water and minerals that are absorbed by the roots
the bacteria needed for nitrogen fixation in root nodules
wax required to coat the surface of actively growing tissue
8
In plants, what happens in the ovary?
pollen is made
eggs wait to be moved to the anther for fetilization
eggs are stored and fertilized
pollen moves there to be fertilized
9
Which of the following is an example of a scientific name?
polar bear
koala bear
black bear
Ursus maritimus
10
Which reproductive strategy is represented by the flower?
pollination
fragmentation
budding
conjugation
11
The male part of the plant is made up of #'s?
1 and 6
4 and 5
2,3 and 5
2, 3 and 4
12
What condition would make the stomata close in a plant?
low oxygen supply
little water available
lots of water available
none of these
13
Where is pollen found?
pistil
<p>stigma</p>
anther
phloem
14
Tiny openings on the surface of plant leaves are called
guard cells
tenticels
air space
stomata
15
The downward growth of roots is controlled by:
chemotropism
phototropism
gravitropism
hydrotropism
16
Plants that have large, underground root systems often live in dry climates. Why is this?
the roots cool the plants when they overheat
the roots help take in carbon dioxide for photosynthesis
the roots make water in times of drought
the roots provide more surface area for water absorption
17
When a shoot from a bean plant touches the trellis, it winds onto it. This is an example of:
gravitropism
hydrotropism
thigmotropism
phototropism
18
What is the correct term that describes the tendency of a plant to grow towards light?
gravitropism
hydrotropism
thigmotropism
phototropism
