Eukaryotic cells have extra features compared to prokaryotic cells. what does this provide indirect evidence for?
that eukaryotes evolved from prokaryotes
eukaryotic cells have organelles, most of which form membrane-bound compartments. being in a compartment, the chemicals involved in a particular process are kept separate from the rest of the cytoplasm. what does this allow ?
allows chemical reactions to take place quickly and efficiently
what processes do eukaryotic cells use to form new cells?
- mitosis
- meiosis
description of plasma membrane in eukaryotic cells
- membrane found on cell surface and most internal organelles
- made up of phospholipid bilayer which also contains embedded proteins
what is the function of the plasma membrane in eukaryotic cells ?
- selectively permeable
- allows cell identification
description of nucleus in eukaryotic cells
- surrounded by 2 membranes nuclear pores allow movement of substances between nucleus and cytoplasm
- contains chromosomes
- has one or more nucleoli
what is the function of the nucleus in eukaryotic cells ?
- DNA contains genetic codes for a making proteins
- nucleolus manufactures ribosomes
What are chromosomes?
long, linear DNA molecules associated with histone protein
description of mitochondrion in eukaryotic cells
- oval shaped organelle surrounded by 2 membranes
- inner membrane folded & forms cristae
-fluid inside called matrix
- contains DNA like that in prokaryotes
what is the function of mitochondrion in eukaryotic cells ?
- produces ATP from aerobic respiration
- ATP is used by the cell for active process, active transport, protein synthesis
