Ch 3: Cellular And Memebrane Organelle Flashcards
Nucleas
Membrane with pores that stores DNA
What are chromatin turned into during cell division?
Chromosomes
What happens to chromosomes during cell division
During cell division chromosomes are split up into sister chromatids, that are held together by centromere’s.
What holds mitotic spindles together
Kinetochore
What are centrioles
They separate chromosomes during cell division
 ribosomes
Sites of protein synthesis; to produce proteins
Types of ribosomes
- free (cytoplasm)
- Attached to rough E.R
- nucleolus
Mitochondria
- major site of ATP
-membranes (inner & outer) - power house of the cell
What are the two membranes of the mitochondria
- Cristal: infolding of inner membrane
Matrix: located in space formed by inner membrane
Rough E.R
- ribosomes attached
- to produce proteins
Smooth E.R
- produce lipids
- to detoxify the body
- found more in the liver
Golgi apparatus
- modify, package, and distribute proteins and lipids for secretion for internal use
Lysosomes
- vesicles that contains digestive enzymes
- Used to digest substances
Stages of the cell lifecycle
- Interphase
- Mitosis
- Prophase
- Metaphase
- Anaphase
- Telophase
 interphase
 longest phase of cell cycle
- G1: cell grows
S- phase: synthesize DNA
G2: Growth and prepare for cell division
