Zoobot Unit 1 test review UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Pollination - CORRECT ANSWER - Transfer of pollen from a stamen to a pistil
Cuticle - CORRECT ANSWER - Outer waxy coating of plant leaves, prevents water loss
Rhizoids - CORRECT ANSWER - Rootlike filaments which attach mosses, ferns to
ground
Thallus - CORRECT ANSWER - Multicellular PLANT BODY found in bryophytes
Oogamus - CORRECT ANSWER - Containing gametes that are not similar
Gemma - CORRECT ANSWER - Bud-like body that separates to form new organisms
Photonema - CORRECT ANSWER - Threadlike chain of cells that form earliest stage of
bryophyte life cycle
Gametophyte stage
Xylem - CORRECT ANSWER - Vascular tissue with hollow cells that conducts water and
minerals
Phloem - CORRECT ANSWER - Vascular tissue that transports organic nutrients from
photosynthesis
Frands - CORRECT ANSWER - Leaflike structures on ferns
, Carpel - CORRECT ANSWER - the female reproductive organ of a flower consisting of
an ovary, stigma, and usually a style
Vascular tissue - CORRECT ANSWER - Transports water and nutrients
Alternation of generations - CORRECT ANSWER - Life cycle that alternates between the
diploid and haploid stages
Anther - CORRECT ANSWER - Part of the stamen that contains the pollen
Gametophyte - CORRECT ANSWER - Haploid part of life cycle, produces gametes by
mitosis that unite to form zygote
Sporophyte - CORRECT ANSWER - Diploid part of life cycle, produces haploid spores
by meiosis
What is double fertilization? List all the steps involved after pollination occurs. Why is it
important for a plant? - CORRECT ANSWER - Process in forming zygote and endosperm.
Pollen grain lands on stigma and grows a pollen tube down to ovary
1 sperm -> 2 polar nuclei = endosperm
1 sperm -> egg = zygote
Nutrition for the seed
Where are the seeds of angiosperms? - CORRECT ANSWER - In the fruit
The fusion of two gametes results in what kind of sporophyte? - CORRECT ANSWER -
Diploid sporophyte
