How Do Plants Make Their Food Test 1

• Oxygen is released during the process of photosynthesis.
• Photosynthesis is the process by which green plants produce glucose.
• It involves the conversion of carbon dioxide gas, water, and minerals the plants take in from their surroundings into sugar and gaseous oxygen.

• Cactus is a desert plant.
• To prevent (reduce) the loss of water leaves are reduced to spines and the stem is modified to a fleshy part that stores water and performs photosynthesis.

• In radish, food is stored in roots.
• Raddish, Beetroot, Carrot are some more examples of plants in which food is stored in roots.

Leaves have tiny pores called stomata.

Through the stomata the exchange of gases takes place.

Green parts of a plant contain chlorophyll pigment.

Chlorophyll pigment helps in the synthesis of food.

Chlorophyll is essential for plants to synthesize its food.
Plants use Chlorophyll and light to make food.
Chlorophyll gives green colour to plants.

Photosynthesis is the only process that releases oxygen.

Maize is a cereal.

Cereals store food in their seeds.

Starch turns blue-black when iodine solution is added to it.
If we add Iodine Solution to Peeled Potato which is a starch, The peeled Potato turns blue- black.
This confirms the presence of starch in potato.

The leaves of most plants are green, because the leaves are full of chemicals that are green.
The most important of these chemicals is called “chlorophyll” and it allows plants to make food.
