Prophase
Chromatin becomes visible.
Nuclear membrane disappears
Metaphase
In metaphase, the chromosomes
line up across the middle of the cell.
Anaphase
The chromatids separate. They are
pulled apart to opposite sides of the
cell.
Telophase
Two new nuclear membranes forms
around each group of chromosomes.
Cytokinesis
Division of the parent cells cytoplasm
Mitosis
The part of the cell cycle during
which the nucleus divides.
DNA
A molecule that contains the
information that determines the
traits that a living thing inherits and
needs to live.
Chromatin
Made up of DNA and proteins
The four phases of Mitosis
Prophase, metaphase, anaphase, telophase
Why is it important for DNA
To make sure that after cell
to be duplicated before mitosis?
division it gets the exact copy
Where is DNA found?
Nucleus
During interphase
Growth, DNA replication, prepare to
divide
In cytokinesis
the cytoplasm divides and
2 new cells are produced
Cell produces organelles in which phase?
Interphase
Chromatids are held together by a
Centromere
Binary Fission
Equal separation of cytoplasm
Ex. Bacteria, Amoeba, paramecia
Budding
Unequal separation of cytoplasm
Ex. Yeast, Hydra
Parthenogenesis
Unfertilized egg develops into young
Regeneration
Regrow body parts (starfish)
Sporulation
New growth grows after spore formation
Ex. Mushrooms and bread mold
Vegetative Propagation
Runners lead to new growth of a plant
Gamete
Sex Cells
Meiosis
Two divisions of the nucleus making
sex cells (gametes)
Fertilization
The process of sex cells (gametes) combining
Zygote
A fertilized egg
Diploid
Having the full # of chromosomes
Humans have 46 total
Haploid
Having half the # of chromosomes
Human sex cells have 23
Only animal cells have this organelle
to help during mitosis
Number of daughter cells produced
during meiosis
Eggs and sperm
Controls cell activity with coded instructions
Centrioles
4
examples of gametes (sex cells)
DNA
Longest stage of the cell cycle
Interphase
Requires 2 parents
Sexual reproduction
