Science Q2 Review - (A)sexual Reproduction Flashcards
reviewer ko 'to ‼️‼️
True or False:
Reproduction is one of the characteristics of organisms.
True
How do organisms preserve their specie?
Organisms produce new organisms that have the same traits as them.
The ability of organisms to produce their own kind.
Reproduction
Two ways organisms reproduce.
Sexual and Asexual
Refers to the process of producing offsprings from one parent, without the union of gametes.
Asexual Reproduction
True or False:
Asexual reproduction requires more than one parent.
False
Ace reproduction requires only one parent.
A type of ace reproduction wherein the cell splits into two or produce two identical offspring.
Binary fission
True or False:
Bacteria reproduce through binary fission.
True
A type of ace reproduction in which the parent cell produces a bud on its surface.
Budding
True or False:
Yeast is an examples of microscopic fungus that reproduces by binary fission.
False
[DYK?] One yeast cell can actually produce 24 daughter cells.
(Yeast reproduce by budding.)
A type of ace reproduction where an organism splits into fragments.
Fragmentation
Ex. of organisms that produce by fragmentation
Cyanobacteria (blue-green bacteria), Lichens, and Sponges.
True or False:
These fragments develops into organisms with nothing in common with their parent.
False
These fragments mat develop and mature into new organisms with the exact same copy of their parent’s genetic material.
A special type of ace reproduction. It can replace an injured or lost body part.
Regeneration
True or False:
In some cases, the generated body part can grow into a whole organism.
True
It bears a number of nodes or “eyes.”
Tuber
Potatoes and dahlias reproduce by this method of ace reproduction.
Tuber
An horizontal underground stem, where each node gives rise to a new plant.
Rhizome
An underground vertical stem, it thickens as it continues to grow.
Example: Gabi
Corm
A special bud that is thick and fleshy.
Bulb
The _ _ serves as storage of food during the period of dormancy to enable plants to survive adverse conditions.
Bulb
True or False:
Onions and water hyacinths are plants that reproduce through their bulbs.
True
A stem that grows below the ground.
Runner / Stolon
The reproductive parts in angiosperms (flowering plants).
Flowers
The two essential parts of flowers
Accessory and reproductive organs
True or False:
Accessory organs are directly involved in reproduction
False
Function of accessory organs
To protect and attract possible pollinators
The outer part of the flower
Perianth
The perianth is composed of
corolla and calyx
Modified leaves that protect and enclose the flower esp. during the bud stage
Calyx
The colorful modified leaves in the flower
Corolla
True or False:
The bright color of the corolla attracts some insects and birds for pollination
True
The collective name for the stamen
Androecium
It contains the anther and the filament.
Stamen
It contains the pollen grains – which have the sperm cells.
Anther
collective name for the pistil
Gyneocium
Where is the stigma located?
The stigma is located at the tip of the pistil.
This is where ovules are contained.
Ovary
Serves as a bridge from the stigma to ovary.
Style
It contain the egg cells.
Ovules
Thr transfer of pollen grains from the anther to the stigma.
Pollination
Pollination may be classified as?
self-pollination
or cross-pollination
The transfer of pollen grains from the anther to the stigma of the same flower.
self-pollination
The transfer of pollen grains from the other of the flowers to the stigma of another flower.
cross-pollination
It involved the fusion or union of gametes from the male and female organisms
Sexual reproductin
Two types of fertilization
external and internal
True or False:
In external fertilization, fertilization can take place after the sperm reaches the egg.
True
This type of fertilization takes place inside the body.
Internal fertilization
The process of producing an egg that is developed and hatched outside the body.
Oviparity
It involved an egg inside the maternal body.
It stays intil it is ready to hatch.
Ovoviviparity
It involves producing live young from the mother’s womb.
Viviparity
