Life Processes in Plants

Answer

The four essential requirements for plant growth are: 1) Sunlight - provides energy for photosynthesis, 2) Water - needed for photosynthesis and transport, 3) Carbon dioxide from air - raw material fo

Answer

Photosynthesis is the process by which plants prepare food in the presence of sunlight and chlorophyll using carbon dioxide and water. Word equation: Carbon dioxide + Water → Glucose + Oxygen (in the

Answer

Leaves are called 'food factories' because they contain chlorophyll (green pigment) that captures sunlight and uses it along with carbon dioxide and water to produce glucose (food) through photosynthe

Answer

Chlorophyll is a green pigment present in leaves that gives them their green color. Its main role is to capture sunlight efficiently and use this energy to convert carbon dioxide and water into glucos

Answer

To test for starch: 1) Boil the leaf for 5 minutes to soften it, 2) Dip in alcohol and heat in boiling water to remove green color, 3) Place decolorized leaf on a plate, 4) Add a few drops of iodine s

Answer

Stomata are tiny pores present on the surface of leaves (mainly on the lower surface). Their main functions are: 1) Allow exchange of gases - carbon dioxide enters and oxygen exits during photosynthes

Answer

Carbon dioxide is essential for photosynthesis. In the caustic soda experiment, when half a leaf was placed inside a bottle containing caustic soda (which absorbs CO₂), that part did not produce starc

Answer

Besides glucose, oxygen is produced during photosynthesis. This can be demonstrated by the aquatic plant experiment where bubbles of oxygen gas are released and can be collected in an inverted test tu
