Which of the following helps to reduce the lose of water from a plant?
the arrangement of palisade mesophyll cells
the presence of xylem
the waxy layer of cuticle
the arrangement of spongy mesophyll cells
The water lose from a plant through the

phloem
stomata
epidermis
The opening of closing of stomata is controlled by the...

phloem
During day, stomata usually..
closed
opened
shrink
expand
During photosynthesis, this substance enter the leaf through the stomata.
water

carbon dioxide
oxygen
In plants, water can lose through these processes...

Guttation
Secretion
The water droplets which formed through guttation is known as....
water vapour
tears
dew

Choose the factors which can affect the rate of transpiration.
temperature
humidity
light intensity
air movement
The following factor can also affect the rate of transpiration..
the number of leaves
the number of flowers
the number of stomata
the amount of water in the soil
Which situation can increases the rate of transpiration?
A plant without leaves
A plant placed under the roof
A plant placed in the room with air conditioner
A plant placed in front of a table fan with speed 2
Vascular bundle consists of...
stem
xylem
root
phloem
Function of xylem is to....
transport the product of photosynthesis
transport water from the root
transport minerals from the root to the leaves
transport water and minerals from the root to the leaves
The diagram shows the arrangement of vascular bundle found in..
root
leaf
stem
flower
The function of phloem is to...
transport minerals from the root to the leaves
transport sucrose formed during photosynthesis from the leaves to other parts of the plant
transport glucose formed during photosynthesis from the leaves to other parts of the plant
transport sucrose formed during photosynthesis from the root to other parts of the plant
the diagram shows a cross section of a leaf. What is X?
Phloem
stoma
xylem
guard cells
The diagram shows a stem which the phloem has been removed. What will happen to the plant after 2 weeks?
The plant die
The upper part of the stem becomes swollen
The lower part of the stem becomes swollen
The root becomes swollen
A few days after the experiment, the plant can still carry out photosynthesis. Why?
The new phloem is produced
The xylem can still transports water and mineral
Photosynthesis is not affected at all
The plant can survives without phloem
