pollination, nutrition and respiration

Pollination
Pollination is an important process in the reproduction of plants that have
____________________ . It is the transfer of pollen from a ____________________ to a ____________________ .
____________________ pollination is the transfer of pollen from the stamen to the stigma
of another plant or of the same plant by an insect or a bird .
____________________ pollination involves wind blowing the pollen from one plant to
another .

Plant nutrition
Plants make their own food . To do this they need ____________________ , ____________________ , ____________________
and ____________________ from the Sun and ____________________ dioxide .

During the process of
photosynthesis , plants release
____________________ into the air .

The ____________________ absorb water and
minerals from the soil . Roots
also fix the plant in the soil .

The water and minerals travel up the ____________________ to the ____________________
passing through the stem vessels .

Plants make food in their leaves . Leaves have tiny pores called ____________________ through
which carbon ____________________ enters the plant . Plants also release oxygen through the
stomata . The leaves are made up of very small cells . Inside these cells are tiny
structures called ____________________ . Each chloroplast contains a green chemical called
____________________ which gives leaves their green colour and absorbs the light from the
sun . Leaves use the light energy to convert water and carbon dioxide into sugar
and oxygen .

Respiration
Plants are living things and so they need to ____________________ , just like people and
animals . During the day they can also use the ____________________ they produce during
the photosynthesis process . At night , however , they must take in ____________________
from the air and release ____________________ dioxide .

Respiration occurs in every cell of the plant . ____________________ is transported to all
plant parts . Some sugar is stored and some is used for respiration
producing energy and releasing water and carbon dioxide .

In ____________________ plants take in carbon dioxide and release oxygen in the
presence of light .

In ____________________ plants take in oxygen and release carbon dioxide into the
atmosphere .

____________________ and respiration help in maintaining a balance between
oxygen and carbon dioxide in nature .
