Question

1. Name the pores through which leaves exchange gases.
2. Name the process by which plant make food.
3. what is photosynthesis.​

Answer 1

Answer: Hope it helps!

Explanation:1. Stomata

2. Photosynthesis

3. The process by which plant make food from simpler substances such as water, sunlight and nutrients

Answer 2

Answer -

1. Stomata

$\longrightarrow$The pores through which leaves exchange gases is called as stomata.

$\longrightarrow$These are the small pores through which gaseous and water exchange takes place.

$\longrightarrow$It is guarded by guard cells which helps in opening and closing of stomata.

$\longrightarrow$It also helps in transpiration which is loss of excess water.

2. Photosynthesis

$\longrightarrow$The process by which plants make their own food is called photosynthesis.

$\longrightarrow$Chlorophyll is the green coloured pigment which trap sunlight ( solar energy ) which is then converted into chemical energy in the form of food and the process is called photosynthesis.

$\longrightarrow$Chloroplast is the site of photosynthesis.

3. The synthesis of organic compounds like glucose from simple inorganic molecules like$CO_2$ and$H_2O$ by the cells of green plans having chlorophyll in the presence of sunlight is called as photosynthesis.

$\longrightarrow$Equation of photosynthesis -

$\implies$$6 CO_2 + 12 H_2O \xrightarrow{\text{sunlight}}C_6H_{12}O_6 + 6 O_2 +6 H_2O.$

━━━━━━━━━━━━━━━

$\longrightarrow$Steps of photosynthesis -

$\implies$ Light reaction - Occur in grana.

$\implies$ Dark reaction - Occur in stroma.
