2.1
Tell what the two classifications of plants.
What is non vascular and vascular plants?
Do angiosperms or gymnosperms produce spores?
What is both?
Describe one way deciduous and evergreen trees differ
What is evergreen trees retain their leaves all year long and deciduous trees drop their leaves in the fall?
In one ways is the alternation of generations different in angiosperms and gymnosperms.
One happens in a cone while one is visible.
Compare xylem and phloem
What is xylem transports water and nutrients through a series of tubes and phloem transports the food the plants makes to all of the cells?
Describe 3 differences between mosses and ferns
What is Mosses are non-vascular plants with simple structures and a dominant gametophyte stage, while ferns are vascular plants with true roots, stems, and leaves and a dominant sporophyte stage?
describe two differences between male and female cones
What is male are small, holds pollen, and not woody, females are big, holds ovules, and woody?
Label all the parts of this flower, then name its male/female parts.
What is Male: Stamen (Pollen, Anther, Filament)
Female: Pistil (Stigma, Style, Ovary, Ovule/Seed)
Contrast diffusion with osmosis.
What is Diffusion is the general movement of any particles (solutes or solvents) from high to low concentration, while osmosis is a specific type of diffusion involving only water movement across a semipermeable membrane, from an area
What are the functions of rhizomes?
What is in vegetative reproduction by spreading horizontally and forming new plants, and as storage organs for carbohydrates and proteins, providing energy for survival during dormancy and regrowth?
describe two characteristics of Gnetophyta
what is nearly leafless; slender branches; flowering with fleshy red cones resembling berries?
Name 3 kinds of differences between Monocots and Dicots.
What is
Monocots, Parallel leaf structure; Petals in groups of 3; 1 cotyledon; Grow from embryo/radicle’s lower end
Dicots, Netted leaf structure; Petals in groups of 4 or 5; 2 cotyledons;Grow from stem nodes?
How do vascular plants compare with non-vascular plants?
What is vascular plants being dominant and widespread, whereas non-vascular plants are restricted to damp environments.
What are spores?
What is reproductive units of plants?
DAILY DOUBLE!!!
Name four different types of Coniferophyta
What is pines, firs, redwoods, junipers, cypresses, spruces, yews?
Explain how insect-pollinated and wind-pollinated flowers work
What is Insect-pollinated - These flowers are brightly-colored, have strong scents, and have nectar to attract pollinators to them. The flowers have a closed design to make sure that the pollinators can’t help but brush past the anthers, (which produce larger, pointier, but fewer pollen grains,) and the sticky stigma, forcing them to transfer/gather pollen to continue to reproduce. These flowers and their pollinators have a beneficial relationship called mutuality and wind-pollinated - These flowers don't look like the flowers above: they have no petals, no bright colors, no strong scents, and don't have nectar, because they don't need pollinators. These flowers have an open design, exposing their anthers (that make small, lightweight, larger?

What is alternation of generations in plants?
What is a life cycle in plants where a multicellular haploid gametophyte generation alternates with a multicellular diploid sporophyte generation.
What plants are in division Pteridophyta?
What is ferns?
Describe what a conifer is
What is a gametophyte phase that occurs entirely within the cone?
What is double Fertilization?
a unique reproductive process in flowering plants (angiosperms) where two sperm cells from a single pollen grain participate in two separate fusion events.
