PLANTS – VOCABULARY AND PROCESSES
PLANT VOCABULARY Roots – secure the plant in
the ground; take the water & nutrients from the soil
Stem – connects the leaves to the roots; helps hold the leaves up to the sunlight
Leaves – grow from the
stem; collect sunlight to make food for the plant
PLANT VOCABULARY Flowers – produce seeds;
attract and feed some pollinating birds and insects
Fruit – contains seeds that
can be planted Seeds – have hard
coatings to protect the tiny new plant parts inside
PLANT VOCABULARY Petals – shelter the inside of the
flower; attracts insects & birds by the color
Sepals – outermost part of the flower to protect the inner parts of the flower
PLANT VOCABULARY Pistil – female part of
a flower
Stamens – male parts of a flower that surround the pistil
Pollen – yellow dust from the stamen that is moved to the pistil during pollination
PHOTOSYNTHESIS Photosynthesi
s (photo – “light”, synthesis – “to put together”) – process of how the plant makes its own food
PHOTOSYNTHESIS
1. Chlorophyll (in green plant cells) collects energy from the sun.
2. The Sun’s energy splits the water molecules (from the soil) into hydrogen & oxygen
PHOTOSYNTHESIS3. The hydrogen joins
with carbon dioxide (that the plant takes in) to make sugar (food). The sugar is not your normal sugar. It’s used to make more complex substances like fats, proteins, etc.
PHOTOSYNTHESIS
4. Sugar is carried to other parts of the plant. Extra oxygen is released into the air.
Light + Water + carbon dioxide = glucose (sugar) + oxygen
TRANSPIRATION
1. Plants absorb water from the soil.
2. Water moves from the roots through the stems to the leaves.
TRANSPIRATION
3. The leaves have a small opening called a stomata. Guard cells surround the stomata & control how much the stomata opens.
TRANSPIRATION
4. Some water from the leaves evaporates through the stomata.
