WorksheetsTransportation in Plants
Total questions: 20
Worksheet time: 10mins
Substances transported in plants are
water
minerals
food
all of the above
Diffusion is a major method of transport of materials in
tall plants
unicellular plants
Multicellular plants
Both (b) and (c)
Diffusion is not effective in
solids
liquids
gases
all of the above
Xylem fibres are made of –
Parenchyma cells
Collenchyma cells
Sclerenchyma cells
Aerenchyma cells
Which of the following do not take part in conduction?
Tracheids
Vessels
Sieve tubes
Fibres
Which of the phloem cells help in storage of food?
Sieve tubes
Companion cells
Phloem parenchyma
Phloem fibres
Absorption of water in plants take place by
osmosis
diffusion
both (a) and (b)
none of the above
Diffusion occurs when molecules move
from lower concentration to higher concentration.
from higher concentration to lower concentration through a membrane.
from higher concentration to lower concentration.
when energy is used.
Ascent of sap in plants takes place through
Cortex
Epidermis
Xylem
Phloem
If the xylem vessels of a plant are plugged
the leaves will turn yellow
no food will be made
the plant will wilt (shrivel)
the plant will continue to grow
Force responsible for the ascent of sap is
capillary force
root pressure
transpirational pull
all of the above
Raisins swell when put in
rainwater
saturated salt solution
mustard oil
saturated sugar solution
The root-hairs are suited for absorbing water from the soil because
they have a large surface area
they have a semi-permeable membrane
they contain a solution of higher concentration than the surrounding water.
all of the above
Transpiration is defined as:
the rise of water up to the stem of a plant.
the elimination of water with dissolved water products.
the loss of water as water vapour from the aerial parts of a plant.
the loss of water as water vapour from the roots as well as the leaves of the plant.
Which one of the following favours the fastest transpiration rate?
A cool, humid, windy day
A hot, humid, windy day
A hot, humid, still day
A hot, dry, windy day
Movement of molecules against a concentration gradient is called
diffusion
osmosis
active transport
all of the above
Nitrogen, Phosphorus and Potassium are examples of
macronutrients
micronutrients
trace elements
all of the above
Deficiency of magnesium leads to
slow growth
yellowing of leaves
curling of leaves
shoots fail to develop
The ‘girdling experiment’ shows that
water is transported by xylem
food is transported by phloem
transport is unidirectional
transport is bi directional
Mineral ions are transported by
diffusion
osmosis
active transport
none of the above
