Question

name: date: 7. looking at a cell under a microscope, you note that it is a prokaryote. how do you know? a. the cell lacks cytoplasm. c. the cell lacks a nucleus. b. the cell lacks a cell membrane. d. the cell lacks genetic material. 8. which structures are involved in cell movement? a. cytoplasm and ribosomes c. microtubules and microfilaments b. nucleolus and nucleus d. chromosomes

Explanation:

For question 7: Prokaryotic cells have cytoplasm, a cell membrane, and genetic material (usually circular DNA in the nucleoid region). The key difference between prokaryotes and eukaryotes is that prokaryotes lack a nucleus.
For question 8: Microtubules and microfilaments are part of the cytoskeleton. The cytoskeleton is involved in cell movement. Cytoplasm is the fluid inside the cell, ribosomes are for protein synthesis, the nucleolus is involved in ribosome production, the nucleus contains genetic material, and chromosomes are structures of DNA and proteins.

Answer:

1. c. The cell lacks a nucleus.
2. c. microtubules and microfilaments
