Topic 7: Characteristics of Living Things

cell theory

• a well-supported explanation that the cell is the fundamental structural unit of living matter

• a hypothesis that cells are only found in plants

• a theory that cells can spontaneously generate from non-living matter

• a statement that all living organisms are made up of tissues and organs

eukaryotic

• having a nucleus and membrane-bound cell parts inside each cell

• lacking a nucleus and membrane-bound organelles

• a type of prokaryotic cell

• a cell type that only exists in multicellular organisms

heterotrophic

• that can produce its own food through photosynthesis

• that cannot make its own food and obtains nutrition and energy by consuming other organisms

• that relies solely on inorganic substances for nutrition

• that can survive without any source of energy

autotrophic

• that makes its own food

• depends on other organisms for food

• is a type of heterotroph

• is a process of photosynthesis

cell

• the basic unit of structure and function in all living things

• a type of organelle found in eukaryotic cells

• a small structure that carries genetic information

• a group of tissues working together to perform a specific function

organism

• a type of cell

• an individual living thing

• a group of similar species

• a non-living entity

multicellular

• made up of more than one cell

• consisting of a single cell

• capable of photosynthesis

• able to move independently

unicellular

• made up of only one cell

• made up of multiple cells

• a type of multicellular organism

• a cell that can live independently

prokaryotic

• made up of one cell that lacks a nucleus and membrane-bound cell parts

• made up of multiple cells with a defined nucleus

• contains membrane-bound organelles

• is a type of virus that can infect bacteria

microscope

• a tool that allows you to see enlarged images of tiny images

• a device used for measuring temperature

• an instrument for recording sound waves

• a machine for analyzing chemical compositions
