asexual Reproduction

Question 1

What is Sustainability

Answer 1

The ability of the environment and the living things it supports to endure into the future.

Question 2

What is Reproductions role in sustainability

Answer 2

Reproduction ensures that organisms have a source of nutrients and energy to sustain their life processes.

Question 3

what does continuity mean

Answer 3

how each species of organism continues to exist over time from one generation to another

Question 4

what is the importance of reproduction

Answer 4

ensures that life exists beyond its present generation. All life depends on the ability of cells to reproduce

Question 5

what are the two ways in which living things can reproduce

Answer 5

sexual and asexual

Question 6

what is asexual reproduction?

Answer 6

offspring come from a single parent. Each offspring recieves a copy of the parent’s genetic material. As a result offspring are genetically identical to the parent and to each other.

Question 7

what is sexual reproduction?

Answer 7

two parents each contribute half of the offspring’s genetic material. As a result, the offspring have genetic information that is different from either parent’s so the offspring are not identical to their parents or in most cases each other.

Question 8

What is the same between asexual and sexual reproduction?

Answer 8

the genetic material and the information it holds is passed on to the offspring

Question 9

Where is the genetic information from the parents contained?

Answer 9

The DNA

Question 10

What are the building blocks of DNA

Answer 10

Nucleotides

Question 11

what is a DNA sequence

Answer 11

the specific Order in which the nucleotides are linked together

Question 12

What is the function of DNA

Answer 12

holds the genetic information that is passed on to offspring

Question 13

how is sexual reproduction different from asexual reproduction

Answer 13

asexual comes from one parent contributing all the parents genetic material and offspring are identical to the parents and to each other.
sexual comes from two parents contributing half of the offspring’s genetic material therefore different from the parents and, in most cases, its siblings.

Question 14

what is binary fission

Answer 14

a type of asexual reproduction in which a cell splits into two daughter cells that have identical genetic information

Question 15

what is a spore?

Answer 15

a structure that produces a new organism by asexual reproduction

Question 16

Explain the cell cycle? and what are the two main stages?

Answer 16

a series of events in the life cycle of a cell. It consists of two main stages: 1) Growth and Development and 2) Cell Division

Question 17

what is vegetative propagation?

Answer 17

asexual reproduction of a plant from part of its roots, stems, or leaves

Question 18

What is budding?

Answer 18

a type of asexual reproduction that involves the formation of an outgrowth, or bud, from a parent cell

Question 19

What is a clone?

Answer 19

An exact copy of a cell or organism

Question 20

How is food poisoning an example of reproduction?

Answer 20

Food poisoning is a result of microbes (example bacteria such as salmonella and E coli) that can reproduce at very fast rates in a short period of time (populations can double in minutes) becoming a threat to our health.

Question 21

what is an eukaryote?

Answer 21

an organism composed of one or more cells that consist of a nucleus and other internal structures that are surrounded by membranes.

Question 22

what are the two ways plant cells can reproduce

Answer 22

asexually and sexually

Question 23

how does a plant cell reproduce sexually

Question 24

what is asexual reproduction in plants called

Answer 24

Vegetative propogation. new plants grow from a portion of the roots stems or leaves of an existing plant becoming clones of the original plant.

Question 25

how does mould reproduce and what is it

Answer 25

moulds reproduce using spores that grow into a mew mould by mitosis. This is considered asexual reproduction because the spores are genetically identical to the mould cells they came from. The spores are released into the air from a structure called the sporangium. when it lands in a good area they begin to grow and further divide by mitosis and cytokinesis and eventually produces more mould.

Question 26

what are the two main stages of the cell cycle?

Answer 26

1. growth and development 2. Cell Division

Question 27

What happens in the cell cycle stage of growth and development?

Answer 27

Interphase: cell grows and he number of organelles increases and the DNA is copies

Question 28

what happens in the cell division stage of the cell cycle?

Answer 28

1. Mitosis (DNA distributed between the two developing daughter cells) and 2. cytokinesis (when those daughter cells separate into independent daughter cells)

Question 29

in what way are yeasts and bacteria similar? and Different?

Answer 29

Both are unicellular organisms. Bacteria are Prokaryotic cells. Yeasts are Eukaryotes and reproduce by the asexual reproduction called budding.

Question 30

What is the proof that bacteria reproduce asexually?

Answer 30

in the process of Binary Fission,, that Bacteria use to reproduce, a parent cell produces two individual and IDENTICAL CELLS (Daughter cells) containing the same DNA

Question 31

what is the difference between binary fission and budding?

Answer 31

binary fission is a type of asexual reproduction where by a cell splits into to two daughter cells that have identical genetic information. Budding is a type of asexual reproduction that involves the formation of an outgrowth, or “bud” from a parent cell (the bud is still identical to the parent like a binary fission process).

Question 32

How does mould form on bread by asexual reproduction?

Question 33

AWhat is vegetative reproduction and describe an example of how it occurs in nature and how it can be used by industry?

Answer 33

vegetative reproduction is the asexual process plants use to reproduce. This means new plants grow from portions of the roots, stems, or leaves of an existing plant. These are called clones of the parent plant.

Example. Sometimes Dad doesn’t know how to buy good potatoes and he buys potatoes with growths on it. those growths are the result of my dad leaving the potatoes out too long and and new roots and shoots have grown from the “eyes” of the potatoes. I we were to plant those a potato plant would grow and it would be an identical copy of the original potato.

there are many examples of how vegetative reproduction can be used in industry but my dad likes grafting. Grafting means taking the bud of the stem or a cut section of the root of a plant and joined to another. Wine Makers use this to use the root of good grape vines from other parts of the world to the stems of grape vines that have been planted to leverage the health of the indigenous stem with the bud of a non native grape variety.
