Question

part i: determine if each sentence is true or false.

1. prokaryotes contain genetic material.
2. prokaryotes do not have a nucleus.
3. prokaryotes contain membrane - bound organelles.
4. prokaryotes are smaller and less complex than eukaryotes.
5. eukaryotes have a nucleus.
6. eukaryotes evolved more recently than prokaryotes.
7. eukaryotes do not have a cell membrane.
8. eukaryotes do not contain membrane - bound organelles.

part ii: fill in the blanks using the words from the word bank.
word bank
cytoplasm dna eukaryotes simpler eukaryotic nucleus organelles bacteria
unicellular. complex prokaryotic membrane ribosomes prokaryotes animals

1. there are two major types of organisms: __________ and eukaryotes. prokaryotes have ________ cells, and eukaryotes have __________ cells,
2. both types of cells have a cell __________, ________, ________ and __________.
3. __________ have a ________ and a variety of cellular __________.
4. prokaryotes are considered __________ organisms, and eukaryotes are more __________.
5. prokaryotes are always ____________ while eukaryotes can have one or more cells.
6. examples of prokaryotes include __________ and archaea. examples of eukaryotes include plants, __________, fungi, and protists.

Explanation:

• For statements 1 - 8:
• Prokaryotes have genetic material (DNA), no nucleus, and no membrane - bound organelles. They are smaller and less complex than eukaryotes. Eukaryotes have a nucleus, evolved more recently than prokaryotes, have a cell membrane, and contain membrane - bound organelles.
• For fill - in - the - blanks 9 - 14:
• The two major types of organisms are prokaryotes and eukaryotes. Prokaryotes have prokaryotic cells (simple), eukaryotes have eukaryotic cells (complex). Both have a cell membrane, cytoplasm, DNA, and ribosomes. Eukaryotes have a nucleus and organelles. Prokaryotes are simpler, unicellular. Bacteria are prokaryotes, animals are eukaryotes.

5. True
6. True
7. False
8. False
