About Stomata Diagram Class 10

Stomata are microscopic pores on a leaf's surface that open and close to control gas exchange and water loss. This model labels the guard cells that control each pore's opening.

Why It's Important

  • Lets carbon dioxide in for photosynthesis
  • Releases oxygen produced during photosynthesis
  • Controls water loss from the leaf
  • Helps the plant respond to its environment

Observation Points

  • Locate the guard cells surrounding each pore
  • Notice how the pore's size can change
  • Consider which gases move in versus out
  • Identify where stomata are most concentrated on the leaf

Learning Objectives

  • Identify the structure of a stoma and its guard cells
  • Explain how stomata control gas exchange
  • Describe why plants close stomata in dry conditions
  • Understand the role of stomata in photosynthesis

Summary

Stomata, controlled by their guard cells, open to let carbon dioxide in and oxygen and water vapour out, balancing photosynthesis with water conservation.

Guard CellsControl whether the pore is open or closed
EpidermisOuter leaf layer where stomata sit
MesophyllInner leaf tissue where photosynthesis occurs

How It Works

Guard cells change shape to open or close the pore
↓
When open, carbon dioxide enters for photosynthesis
↓
Oxygen and water vapour exit through the open pore
↓
Guard cells close the pore to conserve water when needed
