Cell growth and division quiz review

What are advantages of asexual reproduction? (pick all that apply)

• There is increased genetic diversity

• The cell can reproduce quickly

• Exact copies of the successful cells can be reproduced

• Organisms can adapt to changing environments over generations

Why a cells generally so small?

• Because the molecules they are made of are tiny

• Because more cells can fit into an organism

• Because moving nutrients across cell membranes is more efficient when they are smaller

• Because more daughter cells can be reproduced when fewer resources are being used

What are the structures in a cell that are made of bundles of DNA?

• ribosomes

• mitochondria

• organelles

• chromosomes

What occurs during the cell cycle?

• cells prepare and then divide into 2 daughter cells

• cells are triggered to die off after a certain amount of time

• cells fail to die off and reproduce uncontrollably

• cells travel throughout the circulatory system

During the cell growth phase of cell division, what is occurring?

• cell membranes and walls are forming

• cells are splitting in half

• new protein and organelles are being formed

• chromosomes are enlarging

What is mitosis?

• The fluid in the cell outside of the nucleus

• The area of the cell that contains DNA

• The part of a cell's life before cell division

• The stage of cell division when the nucleus is divided

During which phase of mitosis are the chromosomes replicated?

• prophase

• metaphase

• anaphase

• telophase

During which phase of mitosis are two nuclear envelopes formed?

• prophase

• metaphase

• anaphase

• telophase

During which phase of mitosis do the spindle fibers first attach to the chromosomes?

• prophase

• metaphase

• anaphase

• telophase

What do spindle fibers do?

• They make up the nuclear envelope

• They hold the chromosomes together

• They separate the chromatids

• They give the cell its shape
