Study Notes
Taxonomic Ranking
- Classification is the process of grouping organisms based on their similarities and differences
- The taxonomic ranking is as follows:
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
Kingdom Plantae
- Has four phyla:
- Bryophyta
- Simple stems and leaves
- Single rootlet called rhizoids
- Reproduce by spores
- Pteridophyte
- Simple roots, stems, and leaves
- Vascular tissue
- Reproduce by spores under the leaf
- Coniferophyte
- Seeds grow inside cones
- Roots, stems, and leaves
- Vascular tissue
- Angio Spermatophyta
- Vascular tissue
- Reproduce by seeds in fruits
- Proper roots, stems, and leaves
- Divided into two groups: Monocotyledons and Dicotyledons
- Bryophyta
Monocotyledons and Dicotyledons
- Monocotyledons:
- One cotyledon
- Fibrous roots
- Leaves attached by a sheath
- Leaf veins are parallel
- Dicotyledons:
- Two cotyledons
- Tap root
- Leaves attached by a petiole
- Leaves have a network of veins
Kingdom Animalia
- Has eight phyla:
- Porifera
- Stationary organisms
- Lack tissues and organs
- Body contains a single cavity with many pores
- Cnidaria
- Bag or umbrella-shaped body
- Simple opening which is the mouth
- Ring of tentacles around the mouth
- Platyhelmithes
- Long, flat, unsegmented body
- Some are parasites
- Annelida
- Elongated body divided into segments
- Body has bristles called setae
- Echinodermata
- Body based on a radial pattern of 5 parts
- Segmented body
- Several pairs of jointed legs
- Mollusca
- Soft, moist, unsegmented body
- Muscular foot
- Many have shells
- Arthropoda
- Class Crustacea
- 2 pairs of antennae
- Usually have more than four pairs of legs
- 3 body segments
- Class Arachnida
- No antennae
- Four pairs of legs
- 2 body segments
- Class Insecta
- One pair of antennae
- 3 pairs of legs
- 3 body segments
- Pair of compound eyes
- Class Chilopoda
- Long body with many segments
- Each body segment has one pair of legs
- One pair of antennae
- Class Diplopoda
- Long body with many segments
- Each body segment has 2 pairs of legs
- One pair of antennae
- Class Crustacea
- Chordata
- Class Pices
- Scales
- Gills for breathing
- Fins for swimming
- Cold-blooded
- Class Amphibia
- Soft, moist skin without scales
- Eggs laid in water, adults live on land
- Larvae have gills, adults have lungs
- Class Reptilia
- Dry, waterproof skin with scales
- Lay eggs with a rubbery shell on land
- Cold-blooded
- Class Aves
- Feathers, beaks, and wings
- Lay eggs with a hard shell
- Warm-blooded
- Class Mamalia
- Hair (or fur)
- Feed their young on milk
- Developed brain
- Warm-blooded
- Class Pices
- Porifera
Ecology
- Study of the interrelationships of living organisms with each other and their environment
- Key definitions:
- Environment: combination of factors that surround and act on an organism
- Abiotic: non-living chemical and physical factors
- Biotic: living organisms
- Species: group of organisms of common ancestry that closely resemble each other
- Ecosystem: community of living organisms interacting with each other and with their abiotic environment
- Methods for carrying out an ecological study:
- Quadrat: used to count stationary or slow-moving organisms
- Pitfall trap: used to sample crawling or walking organisms on the ground
- Sweep net: used to sample flying insects
- Line transect: a measuring tape/string with marks at regular intervals
- Belt transect: a strip of fixed width
- Abiotic factors:
- Aquatic factors: affect organisms living in aquatic habitats
- Salinity
- Dissolved oxygen
- Climatic factors:
- Light
- Temperature
- Humidity
- Water availability
- Edaphic factors: connected with the soil
- Water
- Air
- Mineral nutrients
- pH
- Humus
- Aquatic factors: affect organisms living in aquatic habitats
- Types of soil:
- Sand: large and loosely packed particles
- Clay: very small particles
- Loam: moderate water and a fertile mixture of sand, clay, and...
- Food chain:
- A chart showing the flow of energy from one organism to another
- Arrows signal the direction of the energy flow
- Consumers may be classified into:
- Herbivores
- Carnivores
- Omnivores
