Cell division and reproduction

Why do cells need to divide?

• Volume is too small compared to the surface area of the cell

• The cell grows too big and puts a strain on DNA

• surface area is too big compared to the volume of the cell

• Too much DNA is created and can't be held in the cell

How are chromosomes counted?

• number of chromatids

• number of centromeres

• number of chromosomes

• number of homologous chromosomes

What happens in the S phase of interphase?

• Cell growth and repair

• Organelles are copied

• DNA is replicated

• Cell checkpoint

What does the body do if there is an error in the cell cycle?

• The body turns off cell growth

• The body sends more regulatory factors to that area

• The body tells the cell to replicated anyway

• the body tells that cell to die

What is the order of mitosis?

• Metaphase, Anaphase, Prophase, Telophase

• Prophase, Metaphase, Anaphase, Cytokinesis

• Prophase, Metaphase, Telophase, Anaphase

• Prophase, Metaphase, Anaphase, Telophase

What is the difference between cytokinesis in plant cells and in animal cells?

• animal: forms metaplate plants: forms cell plate

• animal: forms metaplate plants: forms cell plate

• animal & plant: cell membrane pinches in, cytoplasm divides

• animal: cell membrane pinches plant: cell plate forms

In which type of conditions to asexual and sexual reproduction happen?

• Asexual: constant conditions, Sexual: Changing conditions

• Asexual: changing conditions, Sexual: constant conditions

• Asexual & Sexual: Constant conditions

• Asexual & Sexual: Changing conditions

What is the biggest advantage of sexual reproduction?

• decrease in population

• increased genetic diversity

• increase in population

• takes longer to reproduce

What is one drawback to asexual reproduction?

• fast reproduction

• offspring will thrive in a changing environment

• only need one cell/organisms to reproduce

• offspring may not survive too much change in environmentv

Some starfish can grow from just one piece of another starfish's body. What is this called?

• Budding

• Fragmentation

• Vegetative Propagation

• Binary Fission
