Cells
Smallest functional unit of life.
Cell
What comes next in the levels of organization?
Cells - Tissues - Organs - ???
Organ Systems
First stage of mitosis in which chromosomes replicate themselves.
Prophase
Name a disadvantage of asexual reproduction.
Less genetic variation
Organisms are the same so they share the same weaknesses
May not be able to adapt quickly to environment changes to survive
Changes in an organism that affect its appearance, how it behaves, and its functions is called _______.
Mutation.
Where do cells come from?
Other existing living cells.
A group of organs that work together is called ____.
Organ Systems
Metaphase
This female organ is responsible for producing the ova in sexual reproduction.
Ovaries
In meiosis II the cell division begins with how many daughter cells?
Two
All cells have a nucleus, which acts like the brain of the cell. Is this statement true or false?
False
Group of cells that work together form _______.
Tissues
The stage in mitosis that results in two new daughter cells being formed.
Telophase
Removal of bad genes from the population is an advantage of sexual reproduction. True or False?
True
The organelle that controls all cell activity and contains the DNA; known as the "brain" of the cell.
Nucleus
Observed box-like compartments of cork tree bark and was the first scientist to give the cell a name.
Robert Hooke
Structure made up of two or more different tissues types that work together to do a certain job.
Organ
The genetic offspring are EXACLTY like the parent cell in meiosis? True of false
False
What asexual reproduction is being demonstrated:
Fully grown parent cells split into two halves resulting in two daughter cells with the exact DNA as the parent.
Binary Fission.
A multi or unicellular organism that contains a nucleus is called ______.
Eukaryote
All cells come from preexisting cells was discovered by this scientist.
Rudolph Virchow
Say the levels of organization in order from largest to smallest.
Organism, organ systems, organs, tissues, cells
What is the correct order of phases of mitosis?
PMAT -- Prophase, Metaphase, Anaphase, Telophase
Sexual reproduction involves which type of cell division?
Both mitosis and meiosis.
A parent cell breaks into pieces and each piece becomes a new offspring.
Fragmentation
