Section 4.1: Types of Reproduction

Exercise 1
Step 1
1 of 2
Asexual reproduction does not need the fusion of gametes (sperm and egg cell) to reproduce. A single cell can be reproduced by binary fission. The offspring has the exact copy of the original parent’s DNA.

Exercise 2
Step 1
1 of 2
The answer is 1. Cloning is the process of replicating genes in order to produce an identical type of plant or organism. Even though they are the same, they still have different DNA inside them.

Exercise 3
Step 1
1 of 2
The answer is 3. Hereditary information is located in genes found in chromosomes. This chromosome is a thread like structure which is coiled tightly and is supported by histones.

Exercise 5
Step 1
1 of 2
The answer is 1. Asexual reproduction requires only one parent and have the same genetic combination as the parent. The resulting offspring may have different variations.

Exercise 6
Step 1
1 of 2
The answer is 4. Cloning is the process of replicating genes in order to produce an identical type of plant or organism. They have the same DNA from the one they are cloned.

Exercise 7
Step 1
1 of 2
The answer is 4. Since they are reproduced asexually, the resistance of the parent cell will be passed on to the offspring thereby producing bacterial cells which have resistance to penicillin.

Exercise 8
Step 1
1 of 2
The answer is 2. Sexual reproduction is the process of making an offspring using an egg cell and a sperm cell. The egg and sperm cell come in contact with one another and then combine the genetic material of both egg cell from the mother and sperm cell from the father.

Exercise 9
Step 1
1 of 2
The answer is 2. Cloning is the process of replicating genes in order to produce an identical type of plant or organism. The offspring would have the same DNA as the parent plant or organism.
