Characteristics of Organisms Part 2 Characteristics of Organisms

Organism- any living thing that meets the six biotic criteria.Organism- any living thing that meets the six biotic criteria.

Biotic Criteria: All living things 1) Are made of cells 2) Obtain and use energy 3) Maintain homeostasis 4) Reproduce 5) Grow and develop 6) Adapt to their environment

Characteristics of Organisms Part 3 Characteristic 1: Organisms are made of cells

Unicellular- organisms made of one single cell.Unicellular- organisms made of one single cell. Multicellular- organisms made of many cells.Multicellular- organisms made of many cells.

Prokaryotes- unicellular organisms, such as bacteria, that lack membrane bound organelles.Prokaryotes- unicellular organisms, such as bacteria, that lack membrane bound organelles. Eukaryotes- multicellular, and some unicellular organisms with membrane bound organelles, such as yeast, plants, and animals.Eukaryotes- multicellular, and some unicellular organisms with membrane bound organelles, such as yeast, plants, and animals.

Organisms are made of cells working together Organism Organ Systems Organs Tissues Cells

The Main Parts of a Cell Nucleus- the brain of the cellNucleus- the brain of the cell Mitochondrion- the powerhouse of the cell.Mitochondrion- the powerhouse of the cell. Plasma Membrane- controls what enters and exits the cell.Plasma Membrane- controls what enters and exits the cell.

The Main Parts of a Cell Ribosomes- produce proteins.Ribosomes- produce proteins. Nucleolus- found inside the nucleus, it produces ribosomes.Nucleolus- found inside the nucleus, it produces ribosomes.

Characteristics of Organisms Part 4 Characteristic 2: Organisms must obtain and use energy

Photosynthesis- the process in which plant cells convert light energy into chemical energy.Photosynthesis- the process in which plant cells convert light energy into chemical energy. Cellular Respiration- the release of chemical energy for cellular use.Cellular Respiration- the release of chemical energy for cellular use.

Food Chain- the transfer of energy through an ecosystem.Food Chain- the transfer of energy through an ecosystem. Food Web- interconnected food chains in an ecosystem.Food Web- interconnected food chains in an ecosystem.

Energy Cycle Decomposers Producers Consumers

Characteristics of Organisms Part 5 Characteristic 3: Organisms must maintain homeostasis

Homeostasis- the ability for organisms to maintain an internal balance needed for survival.Homeostasis- the ability for organisms to maintain an internal balance needed for survival.

Metabolism- the conversion of potential energy to chemical/usable energy.Metabolism- the conversion of potential energy to chemical/usable energy. –Based on the organism’s need, homeostasis regulates how much energy is used or stored.

Characteristics of Organisms Part 6 Characteristic 4: Organisms reproduce

Genesis 1:11 “And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth, and it was so.”

Reproduction- the ability of an organism to multiply and create offspring.Reproduction- the ability of an organism to multiply and create offspring.

Asexual Reproduction- the ability of an organism to multiply and create offspring with its own DNA.Asexual Reproduction- the ability of an organism to multiply and create offspring with its own DNA. Sexual Reproduction- the ability of an organism to create offspring with a member of its own species (and combined DNA).Sexual Reproduction- the ability of an organism to create offspring with a member of its own species (and combined DNA).

Characteristics of Organisms Part 7 Characteristic 5: Organisms grow and develop

Growth- the increase in body mass or formation of new body structures.Growth- the increase in body mass or formation of new body structures. Development- all the changes that takes place during an organism’s life cycle.Development- all the changes that takes place during an organism’s life cycle.

Metamorphosis- series of changes in body structure from egg to adult.Metamorphosis- series of changes in body structure from egg to adult. –Complete metamorphosis- Adult organism looks little like its youth counterpart.Adult organism looks little like its youth counterpart. –Incomplete metamorphosis- Adult organism looks similar, but larger, than youth counterpart.Adult organism looks similar, but larger, than youth counterpart.

Characteristics of Organisms Part 8 Characteristic 6: Organisms Adapt

Adaptation- physical and behavioral characteristics that allow organisms to survive in their environment.Adaptation- physical and behavioral characteristics that allow organisms to survive in their environment.

Organisms must be adapted for:Organisms must be adapted for: –Finding food and water –Surviving climate changes –Protection from predators –Reproduction
