Cell theory Flashcards
Cell theory
The cell theory states that all living things are made of cells, cells are the basic unit of life, and all cells come from other cells.
What are the two types of organisms based on cell composition?
Organisms may be unicellular (composed of one cell) or multicellular (composed of many cells).
What is a cell?
A cell is the most basic unit of life and the smallest part of an organism that are capable of all life processes.
What are the two types of cells?
The two types of cells are prokaryotic and eukaryotic.
What is the difference between prokaryotic and eukaryotic cells?
Prokaryotic cells do not have a nucleus, while eukaryotic cells do.
Prokaryotic cells do not have membrane-bound organelles, while eukaryotic cells do.
How do prokaryotic and eukaryotic cells divide?
Prokaryotic cells divide through binary fission, while eukaryotic cells divide through mitosis.
What is the size range of organisms with prokaryotic and eukaryotic cells?
Organisms with prokaryotic cells are typically unicellular, while organisms with eukaryotic cells can be either uni- or multicellular.
Do prokaryotic and eukaryotic cells have cell walls?
Prokaryotic cells have cell walls made of peptidoglycan, while eukaryotic cells only have cell walls in fungi and plants, which are made of chitin or cellulose.
What are some examples of organisms with prokaryotic and eukaryotic cells?
Examples of organisms with prokaryotic cells are bacteria.
Examples of organisms with eukaryotic cells are animals, plants, fungi, and protists.
What do all cells have in common?
All cells have genetic material (DNA/RNA), cytoplasm, cell membrane, and ribosomes.
What is spontaneous generation?
It is a scientific theory that proposes that living organisms can come from non-living matter.
What is the other name for spontaneous generation?
The other name for spontaneous generation is ABIOGENESIS.
What is an example of spontaneous generation?
Flies spawning in rotten meat is an example of spontaneous generation.
