Pollination & Fertilization
Pollination– the transfer of pollen from the stamen to the pistil.
Fertilization– the joining of an egg and sperm
Germination– the growth or sprouting of an embryo from a seed.
Dormant– the ability of a seed or plant to become inactive, but when conditions are
right, the seed or plant will become active.
Structures & functions of a Plant
Flowers– Flowers are the reproductive organ of a plant.
 Flowers produce seeds during reproduction.
Petals– protect the stamen & pistil.

Petals also attract insects to help spread the pollen or sperm from the stamen to the
pistil.
Stamen– male reproductive organ that produces pollen or sperm

Male sex cell: sperm
Pistil– The female reproductive organ of a flower. Produces an egg in the ovary.

Female sex cell: egg
Leaves– leaves are the food making organ of a plant. During photosynthesis, leaves use sunlight
and chlorophyll to make food.
Stem– stems hold the plant up & supports the leaves & flower.

Stems transport water from the roots to the leaves and flower.
Roots– Roots absorb water & minerals from the soil.
 Roots anchor or hold the plant in place in the soil.
