Study Notes
Classification of Organisms
- Carolus Linnaeus developed a classification system
- Scientists classify organisms based on:
- Cell structure
- Mode of nutrition
- Reproduction
Characteristics of Kingdoms
Animal Kingdom
- Multicellular
- Obtain food by consuming living or once living organisms
Plant Kingdom
- Multicellular
- Make their own food through photosynthesis
Fungi Kingdom
- Most are multicellular
- Obtain food by absorbing nutrients from other living or dead organisms
Protists Kingdom
- Most are single-celled
- Obtain food through photosynthesis, consuming living or once living organisms, or absorbing nutrients
Monerans Kingdom
- Single-celled
- No cell nucleus
- Some make their own food, while others obtain food by consuming living or once living organisms
Examples of Kingdoms
- Monerans: bacteria
- Protists: algae, amoebas, euglena, paramecium
- Fungi: mushrooms, yeasts, molds
- Plants: trees, flowers, grasses, ferns, mosses
- Animals: monkeys, humans, birds, frogs, fish, spiders
Importance of Plants
- Most living things gain energy directly or indirectly from plants
- Plants serve as a source of food and help maintain the Earth's climate
Cell Structure
- The smallest unit of life that can carry out activities
- All cells must:
- Obtain nutrients and energy
- Remove waste products
- Grow
- Reproduce
Cell Types
- Unicellular: made up of one cell
- Multicellular: made up of many cells
Cell Theory
- All living things are made up of cells
- Cells are the basic unit of life
- All cells come from existing cells
Cell Organization
- Cells → Tissues → Organs → Organ System
Organelles
- Structures within cells that enable them to live, grow, and reproduce
Cell Membrane
- Outer layer of the cell
- Allows nutrients in and waste out
- Protects the cell
- Controls incoming and outgoing substances
- Maintains concentrations of various substances
- Selectively permeable
Cytoplasm
- Jelly-like fluid within the cell
- Holds organelles
Nucleus
- Control center of the cell
- Contains the cell's DNA
Mitochondria
- Power center of the cell
- Provides energy for cellular activities
Ribosomes
- Site of protein synthesis
- Cell parts are made of proteins
Endoplasmic Reticulum
- Transportation system of the cell
- Rough ER: ribosomes attached
- Smooth ER: no ribosomes attached
Lysosomes
- Digest food, particles, and cell parts
- Protects the cell by digesting foreign invaders
