Intro to Plants
The study of plants.
What is Botany?
Why bryophytes cannot grow tall.
What is lack of a vascular system?
Presence of this separates pteridophytes from bryophytes.
What is vascular tissue?
A fine dust that contains sperm of seed-producing plants.
What is pollen?
A common name for angiosperms.
What is flowering plants?
A life cycle in which there is a multicellular diploid and a multicellular haploid form.
What is alternation of generations.
How bryophytes obtain water.
What is osmosis?
The dominant phase of the pteridophyte life cycle.
What is sporophyte?
The dominant phase of the gymnosperm life cycle.
What is sporophyte?
A "seed leaf" that develops in the seed and provides nutrients to the seedling.
What is a cotyledon?
A system of tube-shaped structures in plants that provides support and transports nutrients.
What is vascular tissue?
The three main groups of bryophytes.
What are mosses, hornworts and liverworts?
The three main groups of pteridophytes.
What are ferns, horsetails and club mosses?
The most abundant members of gymnosperms.
What are conifers?
The female and male parts of flowers.
What are carpel and stamen?
The part of a plant's life cycle that occupies the largest part of that cycle.
What is dominant generation?
The structures on bryophytes that perform photosynthesis.
What are leafy shoots?
Lack of these separates pteridophytes from gymnosperms and angiosperms.
What are seeds?
The two types of cones on gymnosperms.
What are pollen cones and seed cones?
This female reproductive structure of flowers contains seven nuclei.
What is the embryo sac?
The haploid (1n) part of the plant life cycle.
What is gametophyte?
The only economically useful member of the bryophytes.
What is peat moss?
A cluster of sporangia on the underside of a fern leaf.
What is a sorus?
This component of gymnosperms represents three generations of the plant's life cycle.
What is a seed?
A plant with flower petals in multiples of 5, broad leaves with branching veins and a tap root system.
What is a dicot?
