ANSWERS GRADED A+ (2026)
Tissue - answer-group of cells consisting of one or more cell types that together perform
a specialized function
Organ - answer-An organ consists of several types of tissues that together carry out
particular function
Three Basic Plant Organs - answer-Roots, Stems, Leaves
Fibrous Root - answer-(small or trailing plants) consists of adventitous roots and lateral
roots
Taproot - answer-Develops from the primary root and prevents the plant from toppling
Adventitious Root - answer-Arise from stems or leaves
Absorption of Water and minerals, tissue type - answer-Roots
Root hair - answer-Found near root tip, increase the surface area of the root to get
nutrients (higher absorption rate), tender tissue
Terminal, axillary buds - answer-structure that has potential to form a lateral branch,
thorn or flower
monocots (venation) - answer-parallel veins
, eudicots (venation) - answer-branching veins
Dermal tissue - answer-epidermis, protects plant
Vascular tissue - answer-facilitates the transport of materials through the plant and
provides mechanical support
Phloem - answer-Transports sugars from where they are made to where they are needed
(moves things down the plant)
Xylem - answer-Conducts water and dissolved minerals upward from roots into shoots
(moves things up the plant)
Sclerenchyma - answer-Rigid because of thick secondary walls strengthened with
lignin, dead at functional maturity, include sclerids and fibers
Paraenchyma - answer-Thin/flexible primary walls, lack secondary walls, least
specialized, perform the most metabolic functions, retain the ability to divide and
differentiate
Tracheids - answer-Found in xylem of all vascular plants
Vessel Elements - answer-common to most angiosperms and few gymnosperms, align
end to end to form long micropipes called vessels
Sieve Tube members - answer-Alive at functional maturity though they lack organelles-
each tube element has a companion cell whose nucleus and ribosomes serve both
cells
Companion cells - answer-each tube element has a companion cell whose nucleus and
ribosomes serve both cells
