How Do Plants
Produce Food?
What are the basic parts of the
plants?
Roots, stems, leaves
What are the two main jobs of
ROOTS?
•Anchor the plants
• Take in water and
nutrients
Explain the two different types of
roots.
• Desert Plants: Have
roots that spread out.
• Dandelions: Have one
main root to reach deep
underground.
What is the job of the stem?
•Support a plant and
enable its leaves to
reach the sunlight.
Explain the two different types of
stems.
• Smaller plants: flexible, green
stems (Live for 1 year)
• Larger plants: stiff, wooden
stems (Live for many years)
What is the one main job of the
LEAVES?
To make the food for
the plant
What is the outer layer of the
leaves called?
epidermis
What is the job of the epidermis?
Keeps leaves from drying
out
What does the upper epidermis
do?
Helps keep water in.
What is the lower epidermis called
and what does it do?
• Called stomata
• Open during day to take in
carbon dioxide and make food
• Closed at night to keep the
plant from drying out
What is the loss of water through
leaves called?
transpiration
What connects to the tubes in the
stems, are found in the center of
most leaves, and they help food
and water move within the leaf?
veins
What is the process in which plants
use water from the soil, carbon
dioxide from the air, and energy
from the sunlight to make food?
photosynthesis
What is the job of chloroplasts?
Only cells with
chloroplasts can make
food
What green pigment, or coloring
matter, is located in the
chloroplasts?
chlorophyll
What enables a plant to absorb
light energy so that it can produce
food?
chlorophyll
What percent of oxygen you
breathe is produced during
photosynthesis by plants and
plantlike protists?
90%
Explain the steps of
photosynthesis.
Sunlight provides
energy for plants to
make food.
Plants take in carbon
dioxide.
Leaves release oxygen
through stomata.
Chlorophyll absorbs
energy from sunlight.
Food is stored in
leaves, stems, seeds,
and roots.
Roots take in water
