Sexual and Aesexual Reproduction Flashcards
(42 cards)
What is aesexual reproduction?
Asexual reproduction only needs the involvement of one part of the organism and does not require the presence of male and female parts.
Asexual reproduction produces offspring that are identical to the parent. What is this called?
Cloning
What is the cell division in bacteria?
Binary Fission
What is the cell division in humans?
Mitosis
What is cell division?
The reproduction of cells by duplicating their genetic material
What is parthenogenesis?
The type of asexual reproduction found in females where growth and development of embryos occurs without fertilization by male.
How do fleas, aphids, and only some bees, reptiles and fish reproduce?
Aesexually, through parthenogenesis
What is a runner?
Stem or root that comes out of a plant and produces new roots that create a genetically identical plant
Why do humans grow?
Because the cells in their body reproduce
How do plants reproduce?
By making a seed
How do mushrooms reproduce?
They have spores
How do some animals, like chickens, reproduce?
They lay eggs
What is budding?
When a bud forms on one side of the cell and when it reaches maturity, it breaks off and turns into a new cell
Which organism uses budding?
Yeast
What is regeneration?
When a plant makes a new part to replace lost ones
Cloning is an example of regeneration. What happens in cloning?
When a leaf or a stem is cut off from the main plant, and planted into a moist environment. As a result, a new plant is formed.
How to strawberry bushes, roses, trembling aspen tree reproduce?
By cloning
What is sexual reproduction?
Reproduction that requires both male and female parts
When you reproduce sexually, are the offspring identical?
No, they may share similarities but have genes from both parents
How do plants sexually reproduce?
By spores, cones, or flowers
What is cloning?
When a leaf or stem is cut off from the main plant and put in moist materials to grow a new plant
What are the pros of aesexual reproduction?
- easier and faster because you don’t have to find a mate
What are the cons of aesexual reproduction?
Bacteria, like parasites, figure out a way to enter way easier because they only have to learn one set of DNA because all organisms of that species are identical
What are some examples of organisms that reproduce aesexualy?
Plants, mushrooms, yeast, cells, some fish…
