How does plant structure relate to function? - Answer- — The shape and organization of
cells, tissues, and organs determine how plants perform photosynthesis, transport, and
support. (Why: Example — xylem cells are hollow so water can move efficiently.)
How do plants acquire and manipulate energy and materials? - Answer- — Through
photosynthesis, root absorption of water/minerals, and vascular transport.(Why: This
allows plants to be self-feeding primary producers.)
How do plants maintain homeostasis? - Answer- — By regulating water loss (stomata),
transport systems, and internal chemical balance.(Why: Stable conditions allow
enzymes and cells to function properly.)
How do plants adapt and evolve? - Answer- — Through natural selection acting on traits
that improve survival and reproduction. (Why: Shared ancestry explains similarities
among plant groups.)
What features distinguish land plants from aquatic algae? - Answer- — Cuticle, stomata,
protected embryos, and vascular tissue. (Why: These reduce water loss and provide
internal support on land.)
What is the cuticle? - Answer- — A waxy layer covering leaves and stems.(Why:
Prevents dehydration.)
What are stomata? - Answer- — Openings in leaves that control gas exchange and
water loss. (Why: Allow CO₂ in and O₂ out for photosynthesis.)
How do plant cells differ from animal cells? - Answer- — They have a cell wall,
chloroplasts, and a large central vacuole.(Why: These allow photosynthesis, rigidity,
and water storage.)
How do plant cells differ from bacteria and archaea? - Answer- — Plant cells are
eukaryotic and contain membrane-bound organelles.(Why: This allows more complex
internal processes.)
What is photosynthesis? - Answer- — The process of converting light energy into
chemical energy stored in glucose.(Why: This provides energy for nearly all life on
Earth.)
, Where does photosynthesis occur? - Answer- — In chloroplasts. (Why: They contain
chlorophyll to absorb light.)
What are the light reactions? - Answer- — The first stage of photosynthesis that
produces ATP and NADPH using light energy.(Why: These power the Calvin cycle.)
What is the Calvin cycle? - Answer- — The second stage that uses ATP and NADPH to
fix CO₂ into sugars. (Why: This builds glucose for plant growth.)
What is alternation of generations? - Answer- — A life cycle alternating between diploid
sporophyte and haploid gametophyte. (Why: Combines genetic variation with structural
strength.)
What is the difference between spores and gametes? - Answer- — Spores grow into
gametophytes; gametes fuse to form a zygote.(Why: Different roles in reproduction.)
What is a zygote? - Answer- — A fertilized egg cell.(Why: It becomes the sporophyte.)
What is haploid vs diploid? - Answer- — Haploid has one set of chromosomes; diploid
has two.(Why: Meiosis reduces chromosome number, fertilization restores it.)
Why are plants primary producers? - Answer- — They convert sunlight into chemical
energy.(Why: They form the base of food chains.)
What role do plants play in the oxygen cycle? - Answer- — They release oxygen during
photosynthesis.(Why: Supports aerobic life.)
What is transpiration? - Answer- — Loss of water vapor through stomata.(Why: Drives
water movement and cools leaves.)
What is carbon sequestration? - Answer- — Long-term storage of carbon in biomass or
soil.(Why: Helps reduce atmospheric CO₂.)
What is primary succession? - Answer- — Ecosystem development on bare rock or land
with no soil. (Why: Starts with pioneer species.)
What is secondary succession? - Answer- — Ecosystem recovery after disturbance
where soil remains.(Why: Faster regrowth.)
What is a pioneer species? - Answer- — The first species to colonize a new area.(Why:
They create soil and habitat.)
What are angiosperms? - Answer- — Flowering plants with seeds enclosed in
fruit.(Why: Most diverse plant group.)
