MITOSIS
What is the genetic makeup of the daughter cells after mitosis?
How many cell divisions occur in the process of meiosis?
How many parents are needed for sexual reproduction?
Two parents are needed for sexual reproduction
How many parents are needed for asexual reproduction?
One parent
If a body cell has 17 chromosomes, how many chromosomes will it have after the process of mitosis?
The daughter cell will have 17 chromosomes
What is the definition of mitosis?
Each daughter cell has ________ as much DNA as the parent cell
1/2
Name one advantage and one disadvantage of sexual reproduction
Advantages: Allows for genetic variation, leading to better adaptability in different environments
Disadvantages: Two parents are needed, takes more time than asexual, takes a lot of energy
What is a genetically identical copy of a parent in asexual reproduction called?
A clone
What are mutations?
How many cell divisions occur during the process of mitosis?
One single cell division
How many daughter cells are produced in the process of meiosis?
4 daughter cells
In plants, male and female gametes unite to produce a _______
Seed
Name one advantage and one disadvantage of asexual reproduction
Advantages: Fast & cheap, no mating required, energy efficient
Disadvantages: No genetic variation, low adaptability
What is DNA?
The chemical name for the long, stringy stuff that sits inside cells
What is the difference between mitosis and asexual reproduction?
Mitosis is a type of cell division primarily used for growth and healing.
Asexual reproduction is a process that produces an entirely new, identical organism
Why is meiosis essential for organisms that reproduce sexually?
Because it ensures that offspring have the correct number of chromosomes (half), and it allows for genetic variation.
______ is the male gamete in flowering plants and the eff or ______ is the female gamete
1.) Pollen
2.) Ovum
What is the primary name given to asexual reproduction by bacteria?
Binary fission
TRUE or FALSE: The Komodo Dragon reproduces both sexually and asexually
TRUE
Describe the process of mitosis in detail
Cell is in a resting state, chromosomes duplicate and separate to opposite sides of the cell. Cell divides, and each daughter cell is identical to the parent.
Describe the process of meiosis in detail
1. Cell is at rest with (X) number of chromosomes
2. Chromosomes in the cell double and align in the center
3. Cell divides, and each has (X) chromosomes
4. Cell divides again, now there are 4 cells each with 50% the number of chromosomes
What is a fertilized egg called in sexual reproduction?
A zygote
____________ is a form of asexual reproduction where an embryo develops from an unfertilized egg
Parthenogenisis
What is the difference between identical and fraternal twins?
Identical twins happen when one egg and one sperm are fertilized and split into two embryos.
Fraternal twins happen when two eggs and two sperm are fertilized at the same time.
