Reproduction 1 and 2 (educake)

Question 1

What is the name of the human male gamete?

Answer 1

sperm cell

Question 2

In bacteria what name is given to asexual reproduction?

Answer 2

binary fission,
which literally means “splitting into two”.

Question 3

Which type of microorganism reproduces using spores?

Answer 3

Fungi reproduce via spores. Fungal spores serve a similar function to the seeds of plants.

Question 4

Which type of reproduction only needs one parent?

Answer 4

Asexual reproduction only requires one parent.

Question 5

What is the missing word? An advantage of __________ reproduction is that all good characteristics are passed on.

Answer 5

asexual

Question 6

A disadvantage of sexual reproduction is that _____ parents are needed. What number completes the sentence?

Answer 6

2

Question 7

Does sexual reproduction produce offspring that are genetically identical or different?

Answer 7

genetically different to each other and to the parents.

Question 8

Which type of reproduction requires less time and energy?

Answer 8

Asexual reproduction
it is a much quicker, less energy-demanding process than sexual reproduction. Only one individual is needed.

Question 9

Which type of reproduction occurs by mitosis?

Answer 9

Asexual reproduction

Question 10

What is the name of the human female gamete?

Answer 10

egg cell

Question 11

What is the scientific name for a sex cell?

Answer 11

gamete

Question 12

How many pairs of chromosomes are found in human body cells?

Answer 12

23 pairs of chromosomes

Question 13

How many sets of 23 chromosomes are found in human sex cells (gametes)?

Answer 13

Human sex cells, known as gametes, contain one set of 23 chromosomes as opposed to the 2 sets contained in all other body cells.

Question 14

What is a genetically identical individual made by asexual reproduction known as?

Answer 14

a clone

Question 15

In asexual reproduction, how many parents are needed?

Answer 15

one parent

Question 16

What type of reproduction involves the fusion of male and female gametes?

Answer 16

Sexual reproduction

Question 17

What type of gamete is able to move itself using a tail?

Answer 17

sperm cell

Question 18

True or false? Pollen grains are the female gamete in the plant.

Answer 18

false
They are the male gamete.

Question 19

What is the missing word? A disadvantage of sexual reproduction is that production of offspring is __________.

Answer 19

slower/slow

since a lot of time and energy is invested in producing the offspring.

Question 20

Daffodils and strawberry plants both reproduce using which method?

Answer 20

Daffodils and strawberry plants can reproduce both asexually and sexually.

Question 21

Which type of reproduction gives rise to variation in the offspring?

Answer 21

sexual

Question 22

Malarial parasites reproduce one way in a human host, and another way in a mosquito. Which type of reproduction do they use in a human host?

Answer 22

asexual reproduction

Question 23

In fungi what is produced by asexual reproduction?

Answer 23

thousands of microscopic spores.

Question 24

How many chromosomes will the white blood cell have?

Answer 24

46

Question 25

Malarial parasites reproduce one way in a human host, and another way in a mosquito. Which type of reproduction do they use in a mosquito?

Answer 25

sexual

Malarial parasites reproduce sexually while they are parasitising a mosquito.

Question 26

In humans, how many pairs of chromosomes determine the sex of the individual?

Answer 26

1
In humans, one pair of chromosomes known as the sex chromosomes determines the sex, male or female, of the offspring.

Question 27

During meiosis, sperm cells are produced that carry X or Y sex chromosomes. What percentage of sperm cells carry a Y chromosome?

Answer 27

50% contain an X chromosome and 50% contain a Y chromosome.

Question 28

What is the missing letter? During meiosis, egg cells are produced that only carry the sex chromosome __ .

Answer 28

X

Females inherit an X chromosome from both the egg and sperm making them XX. All egg cells produced as a result of meiosis contain an X chromosome.

Question 29

How many times does a cell divide during meiosis

Answer 29

2

Question 30

Where are sperm cells produced

Answer 30

Sperm cells are produced by meiosis in the testes.

Question 31

What type of cell division occurs when an embryo is developing into a new individual?

Answer 31

mitosis

Question 32

Meiosis only occurs in the __________ organs. What one word completes the sentence.

Answer 32

reproductive

namely the ovaries in females and the testes in males.

Question 33

in meiosis what type of cell will the daughter cells become?

Answer 33

Its become a gamete as they develops into sex cells

Question 34

Fertilisation occurs when which part of the sperm and the egg cell fuse?

Answer 34

Nuclei

Question 36

Fertilisation

Answer 36

the fusion of an egg cell nucleus with a sperm cell nucleus.

Question 37

How many chromosomes will the ovum have?

Answer 37

23

Question 38

How many gametes are formed as a result of one cell dividing by meiosis?

Answer 38

Each time a cell divides by meiosis, 4 new cells are produced.

Question 39

True or false? When a cell divides by meiosis, it forms four identical gametes.

Answer 39

false
When a cell divides by meiosis, the four resulting gametes are not identical to each other.

Question 40

True or false? When a cell divides by meiosis, it forms two pairs of identical gametes.

Answer 40

false

Mitosis can produce genetically identical daughter cells, but meiosis produces genetically unique cells.

Question 41

During the process of meiosis, how many divisions occur?

Answer 41

2

Question 42

in meiosis, how many chromosomes will there be in each of the 4 daughter cells?

Answer 42

23

Daughter cells produced by meiosis each contain 23 chromosomes in their nuclei.
