Unit 2 Lesson 3

Question 1

Asexual reproduction

Answer 1

One organism produces 1 or more organisms that are genetically identical to itself.

The new organisms live independently of the original organism

Question 2

Types of Asexual reproduction

Answer 2

A. Binary Fission - happens in prokaryotes. The parent organism splits in 2
B. Budding - happens in eukaryotes. A bud grows until it forms a full size organism. Result of mitosis
C. Spores - both prokaryotes and eukaryotes. Specialized cells that are light and can be carried by wind
D. Vegetative Reproduction - where new plants can grow from stems, roots or leaves

Question 3

Sexual Reproduction

Answer 3

Each parent contributes a sex cell to the new organism. 1/2 the genes in the offspring come from each parent

Question 4

Fertilization

Answer 4

When a sperm cell and egg cell combine to form a new cell

Question 5

Zygote

Answer 5

The new cell formed when the egg cell and sperm combine

Question 6

Advantages of Asexual Reproduction

Answer 6

1. Happens very quickly
2. Offspring are identical to parent so good traits are passed on
3. Organisms don’t need a partner
4. All organisms can produce more offspring not just females

Question 7

Advantages of Sexual Reproduction

Answer 7

1. It increases genetic variation which increases the chances of survival
