24
Q

a living thing that has an effect on an ecosystem

A

biotic factor

25
a NON-living thing that has an effect on an ecosystem
abiotic factor
26
the smallest structural and functional unit of an organism, typically microscopic
cell
27
any of the district types of material of which animals or plants are made, consisting of specialized cells and their products
tissue
28
a group of organs that work together in the body to perform a complex function
organ system
29
a microscopic unicellular organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Also includes bacteria and cyanobacteria.
prokaryote
30
an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Also include all living organisms other than the eubacteria and archaebacteria. unicellular OR multicellular.
Eukaryote
31
a type of Eukaryote cell that lacks a cell wall and has a true, membrane-bound nucleus with other cellular organelles. unicellular.
animal cell
32
have a cell wall surrounding the membrane unlike a certain type of a cell
plant cell
33
The cell is the smallest living unit in all organisms. All living things are made of cells. A single celled organism is unicellular because it has one cell. A multicellular organism is made of many cells. All cells come from other pre-existing cells.
