Nutrition in Plants Quiz

Nutrition in Plants

• Plants can make their own food through the process of photosynthesis, using water, carbon dioxide, and minerals.

• Animals, including humans, are directly or indirectly dependent on plants for their food.

• Leaves are the food factories of plants, where photosynthesis occurs with the help of chlorophyll and sunlight.

• Water and minerals are absorbed by the roots and transported to the leaves through vessels.

• Carbon dioxide from the air enters the leaves through stomata and is used in photosynthesis.

• Photosynthesis is a unique process that captures solar energy and stores it in the form of food.

• Nitrogen, necessary for the synthesis of proteins, is obtained by plants from soil bacteria or fertilizers.

• Some plants lack chlorophyll and depend on other plants for their food, using the heterotrophic mode of nutrition.

• Insectivorous plants can trap and digest insects for their nutrients.

• Fungi use saprotrophic nutrition by absorbing nutrients in solution form from dead and decaying matter.

• Some fungi can cause diseases in plants, animals, and humans, while others are useful or used in medicines.

• Symbiotic relationships, such as those between fungi and trees or algae and fungi in lichens, involve the sharing of nutrients and shelter.Nutrition in Plants

• Fungi are saprotrophs that derive nutrition from dead, decaying matter.

• Plants like Cuscuta are parasites that take food from the host plant.

• A few plants and all animals are dependent on others for their nutrition and are called heterotrophs.

• Most plants are autotrophs, but some adopt other modes of nutrition like parasitic and saprotrophic.

• All animals are heterotrophs since they depend on plants and other animals for food.

• Insectivorous plants may be considered partial heterotrophs.

• Organisms need to take food to obtain nutrients for growth and maintenance.

• A parasite is an organism that lives on or in another organism and feeds on it, while a saprotroph feeds on dead organic matter.

• The presence of starch in leaves can be tested through simple chemical tests.

• Green plants synthesize their own food through the process of photosynthesis, which involves capturing solar energy through chlorophyll pigments.

• Plants are the ultimate source of food, as they produce organic matter through photosynthesis that sustains all other organisms in the food chain.

• The pores through which leaves exchange gases are called stomata.
