Structure of phloem consists all below, except?
Sieve tube element
Tracheids
Companion cell
Sieve plate
Recall that the movement of food in the phloem is called.
Translocation
Transpiration stream
Evaporation
Respiration
ATP and protein are supplied to sieve tube elements by which other cell?
Xylem vessel
Sieve tube element
Companion cell
Tracheid
Which of the statement is true?
sinks: places where sugar is made
sinks: places where water is made
sinks: places where sugar is delivered to
sinks: places where water is delivered to
Translocation is the
transport of water in the xylem
transport of water in the phloem
transport of sugar in the xylem
transport of sugar in the phloem
Active transport is the movement of substances
from an area of lower concentration to higher concentration
from an area of lower concentration to lower concentration
from an area of higher concentration to lower concentration
from an area of higher concentration to higher concentration
Diffusion is the movement of substances
from an area of lower concentration to higher concentration
from an area of lower concentration to lower concentration
from an area of higher concentration to lower concentration
from an area of higher concentration to higher concentration
How is sugar transported in the plant?
though diffusion which requires energy
through active transport which requires energy
though diffusion which does not require energy
though active transport which does not require energy
The phloem is made up of sieve tube plates and companion cells. The companion cells
has pores to allow sugar to be transported in a continuous flow
provides energy for the transport of glucose
gives company to the phloem
connects xylem to phloem
What is the form of sugar being move to companion cells?
glucose
maltose
sucrose
starch
Movement of sugar from source to other parts of plant is assist by
active transport
diffusion
endosmosis
capillary action
Structure of phloem consists all below, except?
Sieve tube element
Tracheids
Companion cell
Sieve plate
Elements which are transported throughout plants are called
Inorganic
sieve elements
key elements
phloem elements
ATP and protein is supplied to companion cells via
sieve tubes
porous wall
cell wall
vascular tissue
Which of the following statement is true about sieve tube cells?
Sieve tube cells are nucleated but devoid of mitochondria and ER
Companion cells are non-nucleated and regulated by nucleated sieve cell
Sieve tube cells are present in all plants
Companion cells are nucleated and regulates activity of non-nucleated sieve tube
What is the best words to describe sugar source and sugar sink
Both are plants organ and act as storage
Sugar sink can be either roots, fruit or mature leaves and sugar source is shoots
Sugar source act as site for sugar production and sugar sink will store sugar
Companion tube carry food from a sugar source to a sugar sink
Process in which food substances are moved to the rest of plant by phloem is known as
transpiration
respiration
photosynthesis
translocation
Movement of sugar from source to other parts of plant is assist by
active transport
diffusion
endosmosis
capillary action
All events below occurs in sink tissue, except
Water potential increases
Water enters sieve elements from xylem
Higher(+ve) solute potential
Phloem turgor pressure decrease
What is the form of sugar being move to companion cells?
glucose
maltose
sucrose
starch
