25
What are seeds?
A multicellular embryo with a store of nutrients.
26
Examples of gymnosperms:
Conifers, cycads, gnetophytes, and ginkgo.
27
When did gymnosperms evolve?
160 MYA
28
How do gymnosperms reproduce?
By wind pollination.
29
Why are conifers important?
We need them for wood, paper, food (pine nuts, juniper berries (makes gin), and because they make up some of the oldest.
30
What are angiosperms:
The majority of plants on the planet that flower and are used to make food and medicine.
31
When did angiosperms evolve?
135 MYA
32
What is the structure of a male flower?
The anther which produces pollen and the filament which is the supporting stock.W
33
What is the male reproductive structure of a flower called?
The stamen.
34
What is the structure of a female flower?
The stigma which is a sticky tip, the style which is an elongated stalk, and the ovary which contains the ovules.
35
What is the female reproductive structure of a flower called?
The carpel.
36
How do plants attract pollinators?
By tricking bees to mate with the flower and by bribing them with nectar. In both instances, the bee is covered in pollen.
37
How do angiosperms disperse seeds?
Getting carried by the wind, get carried off by an animal, or by attaching to passing animals.
38
What does foxglove do?
Slows your heart rate.
39
What does willow bark do?
Provide pain relief.
40
What does ipecacuanha do?
Causes vomiting.
41
What are the characteristics of fungi?
They are more related to animals, are eukaryotic, lack chlorophyll, contain chitin, are heterotrophic, and can be multi or unicellular.
42
What kingdom do plants belong to?
Plantae
43
What kingdom do fungi fall under?
Fungi (dumbass)
44
How many phyla are in the Fungi Kingdom?
7
45
What are the major groups of fungi?
Yeasts, truffles and mushrooms, and molds.
46
What are the characteristics of fungi?
Feeding by absorbing decaying materials and secreting enzymes.
47
What is the largest organism in the world?
The yellow honey mushroom fungus.
48
What are some harmful fungi for plants?
Wheat rust and dutch elm disease.
49
What are harmful fungi for people?
Yeast infections, jock itch, ringworm, toenail fungus, toxic mold, and aspergillis.
50
What is cedar apple rust?
A disease caused by a fungal pathogen that needs two hosts to complete its life cycle.
51
How are fungi helpful?
We use them for penicillium, cholesterol drugs, bread, alcohol, cheese, and truffles.
52
How do plants and fungi live symbiotically?
Mycorrhizal fungi grow with the roots of plants, receiving sugar in exchange for nitrogen and phosphorous.
53
