Study Notes
Classification Overview
- Classify means to arrange or sort living things based on their characteristics and properties.
- Scientists classify organisms by asking questions related to their appearance, habitat, and food sourcing.
Plant Classification
- Plants are classified by their nutrient transport methods and reproductive processes.
Vascular Plants
- Vascular plants have tubelike structures that connect leaves, stems, and roots.
- These structures transport water and nutrients and provide support for larger growth.
- Examples include trees, ferns, and wildflowers, all of which produce seeds.
Types of Vascular Plants
- Conifers or gymnosperms produce seeds in cones instead of flowers (e.g., Longleaf Pine, Red Cedar).
- Ferns reproduce via spores located on the underside of their leaves.
Nonvascular Plants
- Nonvascular plants transport water and nutrients from cell to cell, lacking tubelike structures.
- Examples include moss, hornwort, and liverwort.
- Moss grows low to the ground due to its nonvascular nature.
Animal Classification
- Animals are classified by the presence or absence of a backbone.
Vertebrates
- Vertebrates are animals with backbones, which include:
- Fish
- Amphibians
- Reptiles
- Birds
- Mammals
Invertebrates
- Invertebrates lack backbones, with arthropods being the largest group.
- Examples of arthropods include insects, spiders, crabs, and shrimp, characterized by segmented bodies and hard exoskeletons.
Identification Tools
- A dichotomous key is a systematic method for identifying organisms through paired descriptions.
Specific Animal Definitions
- Mammals: Warm-blooded vertebrates that provide milk to their young.
- Amphibians: Cold-blooded vertebrates living partially on land and partially in water.
- Fish: Cold-blooded vertebrates adapted to aquatic environments with fins.
- Birds: Warm-blooded vertebrates covered in feathers, breathing through lungs and laying hard-shelled eggs.
- Reptiles: Cold-blooded vertebrates characterized by scaly skin and egg-laying habits.
