Nutrition in Plants

These flashcards cover essential vocabulary terms related to nutrition in plants, including important processes and classifications of organisms.

Autotrophs

Organisms that can make their own food from simple substances like carbon dioxide and water using photosynthesis.

Heterotrophs

Organisms that cannot make their own food and instead obtain food from other organisms, either plants or animals.

Photosynthesis

The process by which green plants make their own food from carbon dioxide and water using sunlight energy in the presence of chlorophyll.

Chlorophyll

A green pigment found in plants that allows them to absorb sunlight for photosynthesis.

Stomata

Tiny pores on the surface of leaves through which plants exchange gases, including carbon dioxide and oxygen.

Saprophytes

Non-green plants that obtain their food from dead and decaying organic matter.

Parasites

Plants that live on or inside another organism (host) and derive food from it.

Nitrogen-fixing bacteria

Bacteria, such as Rhizobium, that convert nitrogen gas from the air into nitrogen compounds usable by plants.

Glucose

A simple carbohydrate produced during photosynthesis, which is then converted into starch and used as food.

Symbiosis

A relationship between two different species of organisms where both benefit, such as algae and fungi in lichens.
