BIOLOGY 1002 TEST 2 2026 TOPICAL QUIZ
COMPILATION CORRECT RESPONSES
◉ -Photosynthetic autotrophs
-cell walls made of cellulose.
Answer: Which of those characteristics are the actual distinguishing
characteristics?
◉ Diploid.
Answer: 2n
◉ Haploid.
Answer: n
◉ alternation of generations.
Answer: Most plants go through a life cycle that involves an
◉ sporophyte; haploid spores; meiosis.
Answer: In this life cycle, the diploid phase produces a ____ that
produces _____ _____ by _____
◉ gametophyte; gametes; fertilization diploid zygote.
,Answer: The spores grow into _____ that produces _____. These
gametes fuse together during ____ to form a _____ ____ that then grows
into another sporophyte.
◉ algae.
Answer: closest relative to land plants
◉ algae.
Answer: since plants (like other organisms) originated in the water,
the most primitive plant types are the
◉ -most or all of life cycle in water tidal forms
-no vascular tissue
-no leaves, stomata, or cuticle
-variation in dominant form of the life cycle
-in some sporophyte is dominant
-in some gametophyte is dominant
-sporophyte and gametophyte can be Heteromorphic or isomorphic.
Answer: The algae traits include:
◉ heteromorphic.
Answer: the sporophyte and the gametophyte have a different
overall appearance
,◉ isomorphic.
Answer: the sporophyte and the gametophyte have a similar overall
appearance
◉ anchoring mechanism: roots
conducting vessels: Xylem and phloem
increased support mechanism: lignin
external protection: cuticle
mechanism for gas exchange: stomata.
Answer: some new traits that appeared in plants as they made their
transition from their origins in water onto plants are...
◉ xylem and phloem.
Answer: parts of the plants vascular tissue system (conducting
vessels). They are vessels that transport water, minerals, nutrients
(especially sugars) and hormones throughout the plant. Plants with
this trait are vascular plants.
◉ lingin.
Answer: a material that is added to the cell walls of "woody" plants.
It increases the stiffness of the cells and allows better support for
the leaves
, ◉ cuticle.
Answer: a layer if waxy material on the epidermal layer of plants
that help prevent water loss of desiccation
◉ stomata (stoma singular).
Answer: openings in the surface (usually underside) of a leaf, which
allow gas exchange but limit water loss
◉ zoospores; xygote.
Answer: When plants transitioned to land, they also had to develop
different means of reproduction for the movement of gametes (_____)
and for the dispersal of spores and seeds (______).
◉ Nonvascular- Bryophytes
Vascular- Tracheophytes.
Answer: As plants moved to land, 2 main categories of land plants
arose
◉ nonvascular.
Answer: the _______ plants did not develop all of the characteristics
required for a complete terrestrial existence and therefore remain
closely linked to water
◉ -no vascular tissue
