How can bacteria be beneficial?
Help decompose dead organisms and return nutrients to the soil
Used to make food
Used to make life-saving drugs
True or False: Cytokinesis is a part of mitosis.
FALSE!
What is programmed cell death?
APOPTOSIS
sister chromatids are being pulled apart by the spindle fibers towards opposite poles of the cell - the cell is elongating. What phase is the cell currently in?
ANAPHASE
True or False: All biomolecules contain carbon, hydrogen and oxygen.
TRUE!
This phase follows the split of chromosomes to opposite poles of the cell.
TELOPHASE
CYTOKINESIS
DOUBLE JEOPARDY
the nuclear envelope has disappeared and the condensed chromosomes are attaching to the spindle fibers extending from the centrioles - what phase is the cell currently in?
PROPHASE
DOUBLE JEOPARDY!
True or False: Enzymes can break down and build up products.
TRUE!
Immediately after G1, a cell can enter one of which two phases?
G0 or S phase
(either the cell will rest until it is needed OR commit to cell division and creating two daughter cells)
What is a mass of cancer cells that interfere with the functions of major organs?
TUMOR
a muscle cell is synthesizing the proteins and organelles needed to prepare for the division of the nucleus - what phase is the cell currently in?
G2
What part of the DNA structure determines genetic information?
sequence (order) of nitrogenous bases
1. cell size
2. DNA replication
An agent that causes mutation is known as a...
a lung cell undergoes uncontrolled cellular growth, creating a mass - the cells go through every phase except...
G0
How is energy converted during photosynthesis?
light energy -> chemical energy
(solar energy -> glucose)
DOUBLE JEOPARDY!
Give 3 reasons why the cell cycle (cell division) is important:
- growth
- development
- reproduction
- survival
- maintenance
- repair
MITOSIS
a skin cell checks for proper DNA replication before continuing to cellular division - what point in the cell cycle is the skin cell currently in?
G2 checkpoint
