Exam Questions and CORRECT Answers
sporophyte - CORRECT ANSWER - the diploid part of the life cycle that produces
haploid spores by meiosis
What is a gametophyte? - CORRECT ANSWER - The diploid part of the life cycle
What does the gametophyte produce? - CORRECT ANSWER - Haploid gametes by
mitosis
What is the result of the union of gametes in the gametophyte? - CORRECT ANSWER -
Fertilization
Anther - CORRECT ANSWER - structures in which pollen grains are produced
Vascular Tissues - CORRECT ANSWER - comprised of the phloem and the xylem; the
main transport system of plants
carpel - CORRECT ANSWER - produce the eggs in the female reproductive part of a plant
Fronds - CORRECT ANSWER - the leaf like parts of a fern, palm, or similar plant
Phloem - CORRECT ANSWER - vascular tissue with hollow cells that transport organic
nutrients from the process of photosynthesis
Xylem - CORRECT ANSWER - vascular tissue with hollow cells that conduct water and
minerals
, Cuticle - CORRECT ANSWER - a protective and waxy covering on leaves
Rhizoid - CORRECT ANSWER - a short, thin filament that anchors the base of a plant and
can take in nutrients
oogamous - CORRECT ANSWER - containing gametes that are not similar; eggs are big
and non mobile; sperm are small and mobile
Thallus - CORRECT ANSWER - not differentiated into stem and leaves; lacks true roots
and a vascular system
ex. algae, liverworts
Gemma - CORRECT ANSWER - bud that can separate to form a new organism (spore)
Pollination - CORRECT ANSWER - the transfer of pollen to the megagametophyte
Protonema - CORRECT ANSWER - a branching filament of cells
What is double fertilization? - CORRECT ANSWER - One of the two generative sperm
fertilizing the egg, forming a zygote
Steps of double fertilization - CORRECT ANSWER - 1. Sperm fertilizes egg
2. A zygote is formed
3. Two polar nuclei form
4. Polar nuclei form an endosperm
Why is double fertilization important for a plant? - CORRECT ANSWER - It gives rise to
an endosperm that provides nourishment for the developing embryo
