Tomato
This root system does not penetrate deeply in the soil
Tap Root System
Fibrous Root System
Primary Root System
Adventurous Root System
Which of the following is NOT true about the root cap?
It is a thimble-like structure covering the tip of the root
It functions in the perception of water in the soil
It protects that apical meristem
It has a slimy substance produced by the outer cap's golgi bodies
Which zone includes the root apical meristem?
Zone of maturation
Zone of elongation
Zone of cell division
Zone of differentiation
In which primary meristem does the epidermis arise?
Periderm
Protoderm
Endodermis
Pericycle
The innermost layer of the cortex which regulates passage of substances to the vascular cylinder is the:
Periderm
Endodermis
Pericycle
Protoderm
___ is a fatty substance that is impervious to water and forms the ___
Suberin; Casparian Strip
Casparian Strip; Suberin
Cutin; Casparian Strip
Casparian Strip; Cutin
Which of the following is true about the casparian strip?
It is made up of cutin which makes it impervious to water
It surrounds the endodermal cell wall parallel to the ground
It regulates the flow of substances to the vascular cylinder
All answers are true
The pericycle is ___ and its function is to ___
adjacent to the endodermis surrounding it; gives rise to lateral roots
the ring surrounding the vascular bundle; gives rise to lateral roots
the ring surrounding the vascular bundle; gives rise to cork cells
adjacent to the endodermis surrounding it; gives rise to cork cells
Which of the following is NOT true about lateral roots?
The lateral roots pushes the cortex and epidermis as it emerges from the established root
The lateral roots are formed by the pericycle
The lateral roots needs to be continuous to the vascular cylinder to allow flow of substances
All answers are true
In a young eudicot root, the ___ has a star-like appearance, while the ___ occupies the indentations between the arms of the star.
Xylem; Phloem
Phloem; Xylem
Roots that are above the ground or that extend to the air
Pneumatophores
Prop Roots
Buttress Roots
All answers are correct
Carrot is a type of root that specializes in
storing food and water for the plant
pulling the plant underground until it reaches the optimal depth
facilitating oxygen in the roots
All answers are correct
Plant roots that produces peg-like roots called haustoria which penetrates the host plant and connect to its conducting tissues are:
Aerial Roots
Storage Roots
Parasitic Roots
Contractile Roots
Which is NOT true about secondary growth of roots?
Part of the pericycle and the parenchyma between the phloem and xylem become the vascular cambium.
With more secondary tissues made, the primary phloem, cortex, and epidermis gets crushed and sloughed off
The vascular cambium produces the secondary xylem to the outside and the secondary phloem to the inside
Secondary growth occurs simultaneously with primary growth
Which tissues are part of the root stele?
Xylem
Phloem
Pericycle
All answers are correct
Which roots is best in preventing soil erosion and absorbing water that does not penetrate deeply in the soil?
Tap Root
Fibrous Root
Primary Root
Secondary Root
Which of the following is true about the route of substances in roots?
The symplast is the continuous connection of protoplast of cells which substances can freely diffuse
The apoplast is the space outside the protoplast which substances can diffuse freely
The casparian strip in the endodermis prevents substances from moving in an apoplastic route
All answers are true
