Science 3.3.1 Flashcards
A fully grown and fully developed organism.
adult
The pollen-producing sac of a stamen.
anther
A type of asexual reproduction in which cell division with mitosis causes new individuals to develop on a parent.
budding
The female reproductive part of a flower.
carpel
The reproductive organ of a conifer. Male cones produce pollen, and female cones produce seeds.
cone
A type of sexual reproduction in which individual cells come together to exchange or transfer genetic material before cell division.
conjugation
A multicellular organism in the very early stages of development.
embryo
An organism that produces only eggs for sexual reproduction.
female
The fusion of an egg and a sperm to form a zygote.
fertilization
The developing offspring of a mammal between the embryo stage and birth.
fetus
A type of asexual reproduction in which a cell splits into two identical cells.
fission
The reproductive organ of a flowering plant.
flower
A type of asexual reproduction in which new individuals develop from pieces of an individual that break off.
fragmentation
A distinct, immature stage of an organism’s offspring.
larva
An organism that produces only sperm for sexual reproduction.
male
A reproductive organ that produces eggs. In flowers, the ovary is part of a carpel and is where eggs are produced in ovules and seeds develop.
ovary
The part of a cone or a flower in which an egg forms through cell division with meiosis. Ovules develop into seeds.
ovule
Reproduction from an egg without fertilization.
parthenogenesis
A flattened organ formed within a uterus to supply nourishment to developing mammals.
placenta
The powdery grains produced in the anthers of a flower. Pollen grains contain sperm formed by cell division with meiosis.
pollen
A plant embryo and its supply of stored food along with a protective coat.
seed
A reproductive cell that can develop into a new organism by itself,without combining with another reproductive cell.
spore
The male reproductive part of a flower.
stamen
The sticky tip of a carpel of a flower. The stigma receives pollen grains.
stigma
The stalk that leads from the stigma to the ovary of a carpel in a flower.
style
A reproductive organ that produces sperm.
testis
Thick-walled, female reproductive organs in which the offspring of vertebrates develop after fertilization.
uterus
A type of asexual reproduction in which nonreproductive parts of an organism can break off and develop into new individuals.
vegetative reproduction
