Question

meiosis worksheet

1. a cell with two pairs of each set of chromosomes is called a diploid / haploid cell. these cells are typically found throughout the body tissues and are called germ / somatic cells.
2. a cell with only one set of chromosomes is called diploid / haploid cell. these types of cells are found in the reproductive organs and are called germ / somatic cells.
3. sperm and egg cells are called gametes / zygotes . a fertilized egg is a gamete / zygote .
4. a type of cell division that results in diploid cells: meiosis / mitosis
5. a type of cell division that results in haploid cells. meiosis / mitosis
6. when a sperm and egg combine, it is called _________________________
7. what is the diploid number for humans? ____ what is the haploid number? ____
8. matching chromosomes are called ______________________________ pairs.
9. when homologous chromosomes exchange genes, it is called: _________________________________

Explanation:

Question 1

Step1: Recall diploid/haploid definition

A diploid cell has two sets (pairs) of chromosomes, haploid has one. Body tissues (somatic) are diploid.

Step2: Select correct terms

So first blank: diploid; second blank: somatic.

Step1: Recall haploid/diploid and cell types

Haploid cells have one set of chromosomes, found in reproductive organs (germ cells).

Step2: Select correct terms

First blank: haploid; second blank: germ.

Step1: Recall gametes vs zygotes

Gametes are sex cells (sperm, egg); zygotes are fertilized eggs.

Step2: Select correct terms

First blank: gametes; second blank: zygote.

Answer:

1. diploid; somatic
