This quiz contains 18 questions from a mix of 1 subtopics.
Which part of the plant is glucose produced in?
Leaves
Roots
Stem
|
What do we call the movement of cell sap (a mixture of sugar and water) up and down the plant?
|
Phloem cells have _________ in their end walls to allow cell sap to pass along the phloem tube.
lignin
stomata
pores
starch
|
What does the xylem transport in a plant?
Water and dissolved mineral ions
Water only
Water and dissolved sugars
|
How do root hair cells absorb water from the soil?
Osmosis
Diffusion
Active transport
|
How do root hair cells absorb mineral ions from the soil?
Active transport
Osmosis
Diffusion
Mass transport
|
Which substance are xylem cells reinforced with to make them stronger?
|
What is transpiration?
The movement of water into the root hair cells
The release of energy in plant cells
The evaporation of water from the leaves
|
What happens to the transpiration rate as the temperature increases?
It stays the same
It increases
It decreases
|
Are stomata normally open or closed during the night?
Open
Closed
|
Why does the rate of transpiration increase if the light intensity is increased?
The stomata open wider to let more carbon dioxide into the leaf for photosynthesis.
The root hair cells become more permeable to water, letting more water into the plant.
The humidity increases, which makes the rate of transpiration increase.
|
What happens to the rate of transpiration if wind speed increases?
It increases
It decreases
It stays the same
|
Why does water loss slow down if a plant is put into a plastic bag?
The humidity increases
The temperature increases
The light intensity increases
|
What is the movement of sugars throughout a plant called?
Translation
Transpiration
Translocation
Transcription
|
Water passes up the plant via the:
Artery
Phloem
Capillary
Xylem
|
Translocation takes place via tubes. These are made up of lots of phloem cells, which are separated by tiny pores that allow cell to pass through.
|
During the summer, where does the primary production of sugars through photosynthesis occur in a plant?
Roots
Stems
Leaves
Flowers
|
Which of the following best describes the role of roots in a plant during the winter season?
Sources, releasing stored nutrients
Sinks, using nutrients for growth
Sinks, storing excess sugars
Sources, actively photosynthesising
