Organism

A living thing with one or more cells

Unicellular

An organism with one cell

Multicellular

An organism with two or more cells

Prokaryote

A cell without a nucleus

Eukaryote

A cell with a nucleus

Nucleus

A kind of bubble that wraps around a cell and it holds nucleic acid

Nucleic acid

DNA or RNA that holds all the information on how to function for every living thing

DNA

holds your genetic information

Protein

A complex molecule made of amino acids. As well as repairing and building tissue

Lipids

Also known as fats they hold long-term energy

Carbohydrates

Also known as crabs they given you quick energy

Water

Made of two hydrogens and one oxygen

glucose

A simple sugar that serves as the main source of energy for the body's cells.

Autotroph

An organism that makes its own food

Heterotroph

An organism that eats other organisms to get energy

Photosynthesis

it is how green plants and some autotrophs make their own food. They turn sunlight, water and carbon dioxide into glucose and ATP

cellular respiration

the process that all living things use to get energy from food

ATP

the main “rechargeable battery” for all living cells. For example a cell uses ATP to do all the things it needs to do

Growth

it’s where a living thing gets bigger over time

development

while it also changing in size it is also learning more skills and becoming more mature

Lifespan

total length of time that an organism exists

Asexual Reproduction

a type of reproduction that only involves one parent. Usually the child will be a clone to the parent

Stimulus

A change in the organisms environment that cause the organism to react

Homeostasis

ability to keep the intervals of an organism balanced despite what’s happening outside

sexual reproduction

Involves two parents and usually child will have a mix of both parents
