Reflection 8/31 – I can explain what is meant by homeostasis and provide an example.

Hierarchy of Life Tissue Organ Organ System Organism Subatomic Part
Molecule Macromolecule Organelle Cell Tissue Organ Organ System Organism Population Community Ecosystem Biome Biosphere
4
Subatomic Particles Protons, Neutrons, and Electrons!
5
ATOMS Smallest unit or particle of matter
Made of Protons, Neutrons, electrons
6
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere Atoms are the simplest form of matter.
7
Molecules 2 or more bonded atoms Forms compounds
8
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere Two or more atoms comprise a molecule.
9
Macromolecule Very large molecules – Carbon molecules
Proteins, fats, carbohydrates, nucleic acids Help build cells
10
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere A macromolecule is a complex of two or more smaller molecules. Most common examples in organisms: proteins, DNA, lipids, and starches.
11
Organelles “Tiny organs of the cell” – ER mitochondria, lysosomes, chloroplast, etc Made of macromolecules
12
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere An organelle is unique functioning part of a cell.
13
Cell Made of organelles – Basic “Unit” of life
Red, white blood, bone, nervous, leaf
14
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere Cells are basic unit of all living organisms.
15
Tissue Similar cells working together at same function. Living
16
Types of Tissues Muscle Epitheleal Nervous Connective
17
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere Tissues are groups of cells functioning the same way together.
18
Organs Tissues that work together same function Stomach heart
Lungs brain
19
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere Organs are parts of a body with unique functions.
20
Systems Organs that work together same function Living Digestive
Respiratory skeletal
21
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere An organ system is a set of organs and tissues working together as one system.
22
Organism Entire living things (organisms) Usually made of systems
May be a single cell
23
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere All the organ systems functioning together in one body make up an organism.
24
Population Same type of organism or species living together
Rattlesnake dolphins, frogs in pond
25
Species Same type of organisms that can mate and produce fertile offsprings.
26
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere Members of one species living together in one area make up a population
27
Community All populations living together in a specific area.
Populations interact – Competition, symbiotic relationships – mutualism, commensalism, paratism
29
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere All biotic..living organisms interacting. Many populations of species living together in one area.
30
Ecosystem A biotic (living) community plus the abiotic (nonliving) parts of an environment. Can be large or small
31
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere Environment—includes abiotic..water, weather, geology—often defined by a natural boundary Ecosystems is a area with all the communities of organisms interact with each other and their common environment: rivers, mountain ranges, canyon, lake, soil types, etc.
32
Biome Large areas of the world with similar climates and organisms.
33
Biosphere Whole living layer around the globe
All the bioitc and abiotic parts of Earth Includes abiotic features
34
Levels of Organization
Atoms Molecules Macromolecules Organelles Cells Tissues Organs Organ systems Organism Population Community Ecosystem Biome Biosphere Ecosystems with similar climate-same temperature and temperature sets conditions for similar organisms.
