Translocation

What molecule is the phloem responsible for transporting?

• Glucose
• Water
• Sucrose
• Glycogen

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

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

Recall which of the following form part of the phloem.

• Sieve-tube elements

• Trachieds

• Vessels

• Companion cells

Cells which transport assimilates in the plant are called ..........?

• Inorganic

• sieve elements

• key elements

• phloem elements

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
