100
What does reproduce mean?
To make new organisms of the same species
100
How many parents are needed for asexual reproduction to occur?
Only 1 parent cell is needed
100
How many parents are needed for sexual reproduction to occur?
2 parents (1 male, 1 female) are needed
100

List the phases of mitosis in order

1. Prophase

2. Metaphase

3. Anaphase

4. Telophase

100

What type of reproduction is Mitosis? Why?

Asexual Reproduction: starting with 1 parent cell and forming 2 daughter cells

200

What is the cell cycle?

The sequence of events that happen in a cell's life including Interphase and Mitosis
200
Are the daughter cells exactly the same as or different from the parent cells?
Exactly the same (identical copies)
200
Are the offspring exactly the same or different from the parents? Why?
The offspring are different because they get characteristics from the father and the mother.
200

At which phase do the chromosomes become visible in the cell?

Prophase

200

What is the longest phase in the cell cycle?

Interphase

300

What is heredity?

Passing genetic material (DNA) from parents to offspring

300
Name the four types of asexual reproduction.
Binary Fission, Budding, Fragmentation/Regeneration, Vegetative Propagation
300
What is fertilization?
When a male cell (sperm) joins with a female cell (egg/ovum) to create a zygote/new organism
300

In which phase do the nuclear envelopes reform around the separated chromosomes?

Telophase

300

The cell cycle phase where the cell grows to its full size, copies the DNA and organelles and prepares to divide is called _________.

Interphase

400

What is a chromosome?

Tightly wrapped DNA that is ready for cell division

400
Which type of asexual reproduction do most bacteria use?
Binary Fission
400

Name an advantage of sexual reproduction

Lots of variation can occur, Variations can help organisms to survive in new environments, Help to protect entire populations from being killed by diseases

400

At what phase in cell division do the spindle fibers pull the chromosomes to opposite poles of the cell?

Anaphase

400

The division (pinching) of the cytoplasm of the cell during cell division is referred to as_____________.

Cytokinesis

500
What do we call the new organism or organisms made during reproduction?
Daughter Cells or Offspring
500

Name an advantage of asexual reproduction

Only needs one parent, happens very quickly, offspring are clones of parents, successful characteristics are guaranteed, requires less energy and time

500

Name a disadvantage of sexual reproduction

Organisms/Cells take a longer time to mature, Must have a mate (2 parents), Gametes (sperm/egg) can be lost, Takes more energy and time

500

Spindle fibers attach to the centromeres and chromosomes line up in the middle of the cell during this phase of cell division.

Metaphase

500

What are the 3 reasons that cells divide using mitosis?

1. Asexual Reproduction

2. Growth

3. Repairing & replacing damaged cells
