Unit 4, Quiz 2 Flashcards
Cells need to reproduce or divide so that organisms can _______ and __________ damaged cells.
- Grow
- Repair
Most of a cell’s life is spent during a period of growth and development. What is this stage called?
Interphase
Directions: Is the following statement true or false?
Interphase is technically a stage of mitosis.
False. Interphase is like the preperation for mitosis. This is the period where chromosomes duplicate themselves. It’s not an active phase of cell division.
Give two examples of cells that are permanently stuck in interphase.
- Nerve cells
- Muscle cells
What is mitosis?
Mitosis is the process in which a eukaryotic cell splits into two new daughter cells, each having the same number of chromosomes as the parent cell
How many chromosomes is a healthy human supposed to have?
46
Name the six stages of mitosis in order.
- Interphase (technically not a part of mitosis)
- Prophase
- Metaphase
- Anaphase
- Telophase
- Cytokinesis
What is asexual reproduction?
The process in which one parent creates two identical offspring
Directions: After being provided the definition, name the term to the best of your ability.
When a new plant grows from a fragment or cutting off of the parent.
This is referring to simple mitosis, in the context of vegetative propagation.
What organisms use simple mitosis (vegetative propagation)?
Both potatoes and strawberries can reproduce through vegetative propagation, which involves simple mitosis.
What is binary fission?
What is an example of an organism that uses it?
- Binary fission is a method of asexual reproduction where DNA is duplicated and the cell grows bigger and splits
- Bacteria
Directions: True or False? If false, correct the statement.
Binary fission only occurs in single-celled organisms (prokaryotic).
True
What is budding?
What are examples of animals that use this?
- Budding is when the parent grows a mini-version of itself that eventually breaks off to form a new organism.
- Some organisms that use this are hydra and jelly fish.
If an organism can make new cells, tissues, or organs after injury, what is this process called?
Regeneration
Directions: True or False? If false, correct the statement.
Regeneration is a form of asexual reproduction that starfish, worms, lizards, and the human liver use.
True
