Photosynthesis Class 10

Vocabulary flashcards covering the definition, equations, internal leaf structures, and process of photosynthesis based on the Class 10 Science curriculum.

Photosynthesis

A process used by green plants and some other organisms to make their own food using light energy.

Conditions Required for Photosynthesis

Sunlight, Chlorophyll, Carbon dioxide ($CO_2$), and Water ($H_2O$).

Word Equation of Photosynthesis

$$\text{Carbon dioxide} + \text{Water} \xrightarrow[\text{Chlorophyll}]{\text{Light}} \text{Glucose} + \text{Oxygen}$$

Chemical Equation of Photosynthesis

$$6CO_2 + 6H_2O \xrightarrow[\text{Chlorophyll}]{\text{Light}} C_6H_{12}O_6 + 6O_2$$

Chloroplast

The site of photosynthesis in a plant cell, containing stroma, thylakoids, and grana.

Stroma

The fluid found inside the chloroplast.

Granum

A stack of thylakoids found within the chloroplast.

Thylakoid

The individual membrane-bound compartments that make up a granum inside the chloroplast.

Glucose

A type of sugar ($C_6H_{12}O_6$) produced during photosynthesis that provides energy to plants.

Starch

The form in which extra glucose is stored in the leaves of a plant.

Stomata

Pores in the leaf used for the exchange of gases, allowing $CO_2$ to enter and $O_2$ to be released.

Palisade Mesophyll

The layer of leaf tissue that contains chloroplasts for photosynthesis.

Spongy Mesophyll

The layer of leaf tissue containing air spaces between cells.

Endothermic reaction

A type of chemical reaction that requires energy (such as light energy) to proceed, a category which includes photosynthesis.

Raw materials for photosynthesis

The essential substances required: Carbon dioxide, water, sunlight, and chlorophyll.

COCO WANTS GO

A mnemonic trick to remember the components of photosynthesis: C (Carbon dioxide), O (Oxygen), C (Chlorophyll), O (Water), WANTS (Light), and GO (Glucose).
