A. Explain why leaves need stomata.  
b. Explain why plants need small amounts of minerals. Describe how they obtain these minerals.​

Explain why leaves need stomata?

Stomata have two main functions, namely, they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breathe. The other main function is regulating water movement through transpiration.

Explain why plants need small amounts of minerals. Describe how they obtain these minerals?

Plant roots absorb mineral salts including nitrates needed for healthy growth. For healthy growth plants need mineral ions including: - Nitrate for producing amino acids which are then used to form proteins. - Magnesium is needed for chlorophyll production.

stomata allow a plant to take in carbon dioxide which is needed for photosynthesis

Explanation:

plants need small amount of minerals to produce amino acids which are then used to form proteins for plant growth. plants Roots absorb minerals needed for healthy growth
