Exercise 31 - Plant Anatomy

Choose the one answer that best answers the question.


1	Which of the following systems functions to absorb water and minerals?
		A)	leaf
		B)	stem
		C)	root
		D)	flower


2	What is the embryological structure that gives rise to the root system?
		A)	radicle
		B)	taproot
		C)	shoot apical meristem
		D)	phyllotaxis


3	What is the function of sieve cells are where are they located in the root system?
		A)	They are located in the xylem and function to transport water.
		B)	They are located in the xylem and function to transport organic compounds.
		C)	They are located in the phloem and function to transport water.
		D)	They are located in the phloem and function to transport organic compounds.


4	How does the root cap protect the root apical meristem as the root grows through the soil?
		A)	The root cap is a thick, dense bundle of cells that acts as a shield.
		B)	The root cap protects the root by secreting mucilage.
		C)	The root perceives the coarseness of the soil and moves into another direction.
		D)	The root cap is not involved with protecting the root apical meristem.


5	What is the primary function of the stem?
		A)	absorb light for photosynthesis
		B)	absorb water and nutrients from the soil
		C)	support the plant and transport water and solutes
		D)	attract pollinators


6	Looking at a stem, how can one determine the length of yearly growth?
		A)	Measure the distance between axillary buds.
		B)	Count the number of lenticels.
		C)	Measure the diameter of the stem.
		D)	Measure the distance between the terminal bud scale scars and the terminal bud.


7	What is girdling and how does it kill a tree?
		A)	Girdling is the process by which all the leaves are stripped away preventing the tree from photosynthesizing.
		B)	Girdling strips away the secondary phloem, disrupting the flow of water to the leaves.
		C)	Girding strips away the secondary xylem, disrupting the flow of photosynthates to the roots.
		D)	Girdling strips away the secondary phloen, disrupting the flow of photosynthates to the roots.Ca. Girdling is associated with the stem system.


8	Which plant system functions mainly for producing food for the plant?
		A)	leaf
		B)	stem
		C)	root
		D)	flower


9	Which form of leaf arrangements has one leaf per node, with leaves appearing first on one side of the stem and then on the other?
		A)	opposite
		B)	alternate
		C)	whorled
		D)	compound


10	Which layer of cells lies just below the upper epidermis of a leaf?
		A)	cuticle
		B)	spongy mesophyll
		C)	palisade mesophyll
		D)	lower epidermis
