During which phase of mitosis do spindle fibers first form?
prophase
When does crossing over occur?
prophase 1
control center of the cell
nucleus
This parts nickname is the Gatekeeper
Cell Membrane
What is the cell membrane composed of?
The cell membrane is composed of lipids
What is condensed genetic material called?
Chromatids
Were during Meiosis 2 do chromosomes line up against?
The Cell's equator
Liquid that carries organelles; the cytosol and the organelles in the cytosol
Cytoplasm
This body part holds the organelles
Nucleus
Endocytosis involves what two processes?
endocytosis involves phagocytosis and pinocytosis.
The point of mitosis is to make
a perfect copy of a cell.
ow many Daughter cells do you end up with at the end of Meiosis 2?
Four Daughter cells.
Power center of the cell; membrane bound organelles; have a double membrane
Mitochondrion
what holds the DNA of the cell?
Chromosomes
What is the difference between passive and active transport?
Passive transport does not need energy, while active transport needs energy.
What structure guides the movement of chromosomes?
Spindle fiber
When do chromosomes line up in a single file?
Metaphase 2
Membrane bound sac; holds nutrients, water, and waste; plant cells have one large vacuole; animal cells help increase cell size during growth
Vacuole
what produces ribosomes?
Nucleolus
Requires the input of energy to move molecules from a low concentration to a high concentration
Active Transport
During which phase does the number of chromosomes briefly double?
Anaphase
When does DNA replication take place?
Interphase
Protects cell and gives them their shape; only plant cells have made up of polysaccharides
Cell Wall
this is the site of protein synthesis
Ribosome
The movement of relatively large quanities of material into or out of a cell at one time
Bulk Transport
