Question

cell theory

1. all living things are made of

although all living things are made of cells, organisms may be:
unicellular - composed of cell
multicellular - composed of cells that may organize into tissues → organ systems

1. cells are the basic unit of life.

it is the smallest part of an organism that is still capable of all of life’s processes.
two types

	prokaryotic	eukaryotic
membrane - bound organelles?	no
division?	binary fission
size of organisms?		uni - or multicellular
cell walls?	yes, made of peptidoglycan	only fungi and made of chitin or cellulose
ex. of organisms with this type of cell?		plants, fungi, protists

all cells have material (dna or rna)

• cytoplasm
• cell membrane

1. all cells come from other cells.

all cells have these four structure, but eukaryotic cells also have membrane - bound

Explanation:

1. The first blank is 'cells' as the cell - theory states all living things are made of cells.
2. Unicellular organisms are composed of one cell.
3. Multicellular organisms are composed of many cells which can organize into tissues, organs, and organ systems.
4. Prokaryotic cells lack a nucleus, while eukaryotic cells have one.
5. Prokaryotic cells do not have membrane - bound organelles.
6. Prokaryotic cells divide by binary fission.
7. Eukaryotic organisms can be uni - or multicellular.
8. Prokaryotic cell walls are made of peptidoglycan, while in eukaryotes, only fungi and plants have cell walls made of chitin or cellulose.
9. Examples of eukaryotic organisms are plants, fungi, and protists.
10. All cells have genetic material (DNA or RNA), cytoplasm, and a cell membrane.
11. All cells come from other cells, and eukaryotic cells have membrane - bound organelles in addition to the basic four structures.
