3. Why leaves are considered as food factories of the plant?
4. Rhizobium bacteria and leguminous plant help each other in survival. What is this relationship known as?
5. What name is given to the relationship between an alga and fungus in lichens?
Answers
Answer:
(3) The leaf is the part of the plant that produces food for the plant by the process of photosynthesis. The leaf has chlorophyll which gives the green color to the leaf. Chlorophyll makes food for the plant using carbon dioxide, water, nutrients, and sunlight.
(4) Rhizobium in return provide help to legumes. they are nitrogen fixing bacteria and they change atmospheric nitrogen in soluble form(nitrate and nitrite) which the plants can easily take from soil to make protein. thus they help each other as there is symbiotic relationship between them.
(5) Like all fungi, lichen fungi require carbon as a food source; this is provided by their symbiotic algae and/or cyanobacteria, that are photosynthetic. The lichen symbiosis is thought to be a mutualism, since both the fungi and the photosynthetic partners, called photobionts, benefit.

Answer:
Answer:Leaves are considered as food factories of plants because
Explanation:
Leaves prepare the food of plants by taking in carbon dioxide and water
Leaves prepare the food of plants by taking in carbon dioxide and waterThey generate glucose in the process of photosynthesis and also release oxygen
Leaves prepare the food of plants by taking in carbon dioxide and waterThey generate glucose in the process of photosynthesis and also release oxygen This glucose is then sent to various parts of plant as food
