Fertilization is the process where a sperm _________ from a male and an egg
_______ from a female join into a single _________.
Any characteristic of a living thing is a ____________.
In asexual reproduction, the offspring is __________ to the parent.
All six kingdoms have organisms that reproduce asexually.
Kingdoms that reproduce asexually:
o Bacteria
o
o Most fungi
o Plants
Animals that can reproduce asexually:
o Jellyfish
o Corals
o
o Echinoderms
Splitting: unicellular protists and bacteria reproduce by ________ into two cells.
Budding: a small part of the parent’s body grows into a tiny and complete
version of the ____________.
Vegetative propagation- produces new plants from leaves, roots, or _________.
Sexual Reproduction Embryo- the beginning of a new ______________.

Inside the________ of a flower, fertilization takes place. The inside of the seed is
where the _________ grows. This seeds contains all the food supply for the
growing embryo. Eventually the embryo will develop enough to make its own
food.

Fruit develops from the ovary and it protects the seed inside. Another form of
protection comes from the seed coat which is tough outer covering.
Notes on Reproduction

Plants that use _____ for reproduction are called conifers and fertilization takes
place inside the cone. After _____________, the developing egg matures into a
seed inside the cone.
Seed dispersal:
o They can be carried by water or by the wind.
o _____________ can move seeds from place to place.
o Animals can eat seeds and as the seeds pass through their
______________ system they deposit them in a new location.
__________ reproduce sexually.

Fish and _______ lay their eggs in water. The water keeps the eggs moist and a


jellylike layer protects the embryos. Food is provided for the embryo from the
________ of the eggs.

Most mammals develop inside their __________. They get nutrients from their
mothers’ bodies as they develop. Monotremes are the only mammals that lay
eggs. All other mammals give birth to live young.

Yeast are _________ that reproduce through budding. Other fungi can
reproduce _____________ by producing spores. Some fungi also reproduce
sexually.

Budding:
o ____________ begins when a small growth, called a bud, forms on the
parent cell.
o As the bud grows, the nucleus in the parent cell ________ in two.
o Each nuclei has identical genetic information.
o On of the nuclei becomes part of the developing bud and eventually
the bud breaks off and lives as a new ________________.
Multicellular fungi reproduce asexually.

Fruiting body: fungal structure that produces spores.

Most fungi can also reproduce ___________. Sexual reproduction occurs when

two hyphae fuse and form a new spore-producing structure.

Asexual reproduction is convenient. An organism does not have to depend on
another ___________ to reproduce. It can live in isolation.

Sexual reproduction promotes variety in a _________. It can give rise to offspring
better suited to environmental changes. Offspring are ______ identical to either
parent. Some are smaller, larger, or faster.
