In biology, a pit refers to a thin area on the secondary cell wall of plants. It appears as a depression on the wall and facilitates the transport of water and minerals between adjacent cells. These pits often occur in pairs with a complementary depression in the neighboring cell, known as 'pit pairs'. This arrangement allows for efficient communication and exchange of fluids between cells.
Pits are crucial for plant growth and development. They enable the transport of essential nutrients and facilitate communication between cells, allowing coordinated responses to environmental changes.
