chapter 25.1- A review of Eukaryotic cells

Question 1

The earliest single-celled eukaryotes were probably single-celled organisms with..

Answer 1

• a cytoskeleton
• an endomembrane system
• A nucleus
• sexual reproduction or different life cycles

Question 2

What is the purpose of the cyto skeleton?

Answer 2

allows for cells to quickly change their shape

Question 3

What are organelles?

Answer 3

a group of membranes that change the shape and package materials for transport.

Question 4

endocytosis

Answer 4

vesicles budding off the cell membrane to bring matieral into the cell

Question 5

excytosis

Answer 5

vesicles budding off the cell membrane to escort things out of the cell

Question 6

What happens during phagocytosis?

Answer 6

a cell surrounds food and then packages them into vesicles from the plasma membrane..

Question 7

What two things are needed for phagocytosis?

Answer 7

cytoskeleton and plasma membrane

Question 8

Ways in which eukaryotic cells are limited compared to prokaryotic cells?

Answer 8

Energy can only be harvest through the mitochandira and photosynthesis in the chloroplast

Question 9

In what ways does cell membrane and a cytoskeleton benefit eukaryotes?

Answer 9

• no cell size limit because diffusion is not needed
• internal movement
• Diverse cell shape

Question 10

How do DNA Replication and Translation benefit eukaryotic cells?

Answer 10

• linear chromosomes means DNA replication can occur at multiple sites
• more control over gene expression

Question 11

Is cell reproduction in eukaryotes diverse ?

Answer 11

Yes cells can reproduce sexually or asexually
