Gymnosperms
What is a Gymnosperms?
A group of woody, perennial seed-producing plants.
What is the role of pollen in angiosperms?
Facilitating fertilization and seed development
What is the primary characteristic that distinguishes dicots from monocots?
Cotyledons
Do biennials self-seed?
Yes
What type of venation is typically found in monocot leaves?
Parallel venation
What are the main groups of gymnosperms?
Conifers, cycads, ginkgoes, and Gnetophytes
How do fruits help in seed dispersal?
Attracting animals to eat them, then dispersing the seeds through their droppings

What are some examples of biennial plants?
Wild cabbage/Hollyhock/Onions/Wood Forget/Black-eyed susan
What is the name of the type of root system typically found in monocots?
Fibrous root system
How do gymnosperms differ from angiosperms?
Seed production and reproductive structures
What is the significance of the endosperm in seed development?
provides nutrients and supports seed growth
What is the characteristic number or multiple of flower parts found in dicot flowers?
Four or five
What happens during the second year of a biennial's life?
The biennials will die and the seed will grow next spring.
What are the two main groups of flowering plants based on the number of cotyledons?
Monocotyledons and Dicotyledons
Give an 3 example of a gymnosperm.
Cycas/Pinus/Araucaria/Thuja/Cedrus/Picea/Abies/Juniperu
What are the two main groups of flowering plants?
monocots and eudicots
Describe the leaf venation pattern typically found in dicots.
Net-like or branched venation pattern
What is a biennial plant?
A plant that, generally in a temperate climate
What are the differences between monocots and dicots?
Monocots have one cotyledon in their seed, while dicots have cotyledon two in their seed.
How does the structure of gymnosperm pollen contribute to their wind-dispersed pollination?
Increase air resistance and surface area, letting pollen grains to float for extended periods and travel long distances.
How does xylem in angiosperms differ from that in gymnosperms?
Primarily in the presence of vessels, which are absent in gymnosperms
What is the typical root system of a dicot?
Taproot system
What happens during the first year of a biennial's life?
Vegetative growth, developing leaves, stems, and roots,
What is a typical example of a monocot plant?
Palms, garlic, onions, daffodils, tulips, and lilies
