Is a biological process in which an organism gives rise to young ones(offspring) similar to itself.
produces the pollen, which contain the male sperm
Male reproductive organ of plant
Female reproductive organ of plant?
is a fusion of male and female gametes produced by the individual
Is the fusion of male and female gametes from different individuals of the same species.
In this method, single individual is capable of producing offspring
Division in half, A kind of asexual reproduction, The cytoplasm then separates, creating multiple daughter cells
Involves the growth of small bulb-like production called bud, It grows and detaches itself from the parent cell to grow independently into a new organism.
Involves breaking down of filaments into fragments that grow into young ones
Process of propagating plants through artificial methods
Methods which involves development of new varieties of fruit plants
Planting a young cutting of a stem with buds into moist soil
Involves of bending of young stem towards the ground and let it grow under the soil for the development of roots.
jasmine
A mass of tissue is selected from the growing tip of the plant
-This is termed as callus
Asexual reproduction is also used in agriculture and horticulture to propagate a particularly desirable plant whose traits would be altered by sexual reproduction, even self pollination.
Some plants reproduce by means of runners or stolon, long slender stem that grow along the surface of the soil
Underground stem
The roots of some plants produce sucker or sprouts, which give rise to new plants
The common names of this plant are based on the fact that numerous plantlets arise from meristematic tissue located in the notches along leaves
The embryos in the seeds may be produced asexually from the parent plant
Some of the plants found ways to share and to scatter genetic materials. Water and air
Trees or fruit bearing plants
Flowering plants
Short term food supplement
plants with one cotyledon
plants that have two cotyledons
Animals which give birth to live offspring
Animal which lay eggs
Female’s egg develops into a new organism without being fertilized by a sperm cell
Predatory cnidarians
Example, Flatworm, Sea star
Occurs in animals where one individual has both male and female reproductive parts
Occurs when an individual reverses sex during its lifetime
Individuals start out life as female and change sex to male
Individuals start out life as a male and change to female
Two component of human reproduction
control maturity of reproductive systems and the development of secondary sexual characteristics to prepare the body for reproductive processes
produce sperm cell
pouch like sac that holds the testis
places sperms into the vagina during mating
transport mature sperm to urethra
provide liquid in which sperm can swim
secretes one of the components of the semen
secretes a milky fluid
mucous secreting glands located at the base of the penis
produce egg cells
passageway of eggs from the ovary to the uterus
place where fertilized egg develops
receives the penis during mating
begin w/ the fusion of sperm and egg cell to form a fertilized egg called a ZYGOTE
The zygote is like a ball of cells attached itself to the uterine lining (endometrium) of the uterus in the process called
when it already attached
Most critical period of embryonic development
All major organs have formed, and the growing individual is now called FETUS
any substance which our body absorbs in order for us to gain energy
intake of food from various sources and the process that converts food substances into living matter.
organisms that obtain energy from sunlight and chemicals to produce their own food
organisms that cannot make their own food and obtain their energy from other organisms
Nutritional requirements of plants
requirement by which organisms convert the energy from sunlight into chemical energy.
used by plants for cellular respiration to release energy from chemical bonds in the sugar to support their growth and maintenance of the bodily processes.
The most important source of nitrogen-fixing bacteria is the symbiotic interaction between soil bacteria and legume plants.
Common in some vascular plants
A parasitic plant depends on its host for survival. Some parasitic plants have no leaves.
An insectivorous plant has specialized leaves to attract and digest insects.
Animals are known as
heterotrophs that obtain nutrients from decaying bodies of plants and animals called detritus by breaking them into smaller sizes before decomposition acts on them
process their food inside the cell.
intake food particles are broken down into smaller components outside the cell.
animals that live in or on their food source
eat relatively chunks of food and have adaptation like jaws, teeth, tentacles, etc.
2nd stage of food processing in animals
5th stage of food processing in animals
start of digestion
helps soften the food
break down the food into smaller pieces
long tube connecting the mouth and the stomach
movement so that food can move easily
seconds for the food to pass from the pharynx down to the esophagus
hours the food will stay in the stomach for the gastric juice to continue the digestive process
controlling the food that passes into the small intestine
