Flashcards

Bacteria characteristics

Bacteria are single-celled organisms found everywhere, lacking a nucleus and requiring a microscope to be seen. They play a role in breaking down materials.

Single-celled organisms

Single-celled organisms consist of one cell, have a nucleus, and are microscopic. They often have feeding tubes.

Plant characteristics

Plants are composed of cells, produce their own food, and usually have flat leaves.

Animal characteristics

Animals move, consume other organisms, and sometimes have flowers. (Some animals do not have flowers)

Study Notes

Bacteria

Found everywhere
No nucleus
Not easily seen with the naked eye
Important for breaking down substances
Reproduce using binary fission

Single-celled Organisms

Found in all water sources
Composed of a single cell
Visible only with a microscope
Have a nucleus
Reproduce using cell division

Plants

Composed of cells
Can make their own food through photosynthesis
Mostly flat structures with leaves
Obtain nutrients directly from the soil and sunlight

Fungi

Large complex organisms
Mostly located underground
Composed of a series of filaments called hyphae
Each filament contains many cells
Fungi grow throughout rotting wood and organic matter
