Unit 2 Flashcards
Who is the father of taxonomy?
Carolus linnaeus
What is the science of classifying things?
Taxonomy
A two part scientific name
Binomial nomenclature
What are two parts in a scientific name
Genus (capital)
Species (not capital)
Why are scientific names used?
- to avoid confusion
- names are universal
- specifics
What are some examples of gymnosperms
Connifers, evergreens, fir, spruce, pine
Which plant type has cones and seeds
Gymnosperms
Pistil
Female portion of flower. Contains stigma, style and ovary
Stamen
Male part of flower. Contains anther and fillament
Stigma
Female portion of flower that is sticky so pollen can stick on it
Style
Stalk that supports the stigma
Ovary
Swollen base of the flower that contains ovules
Anther
Male part of flower that contains pollen
Fillament
Salk holding up the anther
Why are petals colourful?
To help attract pollinators
Sepals
Leafy structures that surround the flower used for protection
Examples of angiosperms
Deciduous trees, heaths, roses, peas, magnolias, dandilions
Examples of protists
Algae, protazoa
Examples of fungi
Mushrooms, yeast, bread molds
Nutrition for protists
Some autotrophs, some heterotrophs (ingestion and absorption) and some both
Nutrition for fungi
Heterotrophs (absorption or secrete enzymes that digest food outside of itself)
Characteristics of viruses
- no cellular structure
- no able to grow and reproduce on their own
- not able to respire independently
- act as parasites
- rely on host cell for survival
Examples of bryophytes
Mosses, liverworts and hornworts
What are the structures that is not a true root but helps bryophytes be anchored to the ground?
Rhizoids
Seed
A complex structure containing an embryo, food, and tough waterproof coating.
What are gymnosperms
Plants with cones or naked seeds
What are examples of gymnosperms
Connifers, fir, spruce, pine
Where are gymnosperms seeds and sperm located
Their seeds are in the female cones while the pollen (sperm) comes from the male cones
Perfect flowers
Flowers that have both male and female parts (stamen and pistil)
Imperfect flowers
Flowers that have either male OR female parts (stamen OR pistil)
Where are the reproductive structures found in angiosperms
The reproductive structures are found within the flower
What are sepals
Leafy structures that surround the flower which are used for protection
What is an endosperm
A 3n structure within the ovule of a plant created when a sperm nucleus fuses with two polar nuclei. The endosperm is a food source for the developing zygote in a seed.
What are some examples of spore producing tracheophytes
Ferns, whisk ferns, club mosses, horsetails
What are some examples of angiosperms
Deciduous trees, heaths, roses, peas, magnolias, dandilions
What are some examples of gymnosperms
Evergreens/ conifers, firs, cone, pine, spruce
What things does the endoderm give rise to?
The digestive tract
What things does the ectoderm give rise to
Skin and nervous system
Operculum
Covering found on gills of fish
What are examples of agnathans
Lamprey
Hagfish
What are some examples of chondrichthyes
Sharkes
Skates
Rays
What are some example of Osteichthyes
