What are subsidiary cells and what is their role in the stomatal apparatus?
Subsidiary cells are epidermal cells near the guard cells that are specialized in shape and size. Their role is to support the function of the guard cells in the stomatal apparatus.
Define stomatal apparatus and its components
Stomatal apparatus is composed of the stomatal aperture, guard cells, and surrounding subsidiary cells.
Describe the relationship between subsidiary cells and guard cells in the context of the stomatal apparatus
Subsidiary cells, specialized in shape and size, support and interact with the guard cells to regulate the stomatal aperture and control gas exchange.
Explain the role of root hairs in the absorption of water and minerals from the soil.
Root hairs are unicellular elongations of the epidermal cells that help absorb water and minerals from the soil.
Describe the characteristics and functions of trichomes in the shoot system.
Trichomes in the shoot system are usually multicellular, and they may be branched or unbranched, soft or stiff, and even secretory. They help in preventing water loss due to transpiration.
Differentiate between root hairs and trichomes in terms of structure and function.
Root hairs are unicellular elongations of epidermal cells that aid in water and mineral absorption, while trichomes in the shoot system are usually multicellular and help prevent water loss due to transpiration.
What is the primary function of root hairs in the epidermis?
Absorbing water and minerals from the soil
How do trichomes in the shoot system contribute to the plant's survival?
Aiding in preventing water loss due to transpiration
What distinguishes root hairs from trichomes in terms of structure?
Root hairs are soft, while trichomes are stiff
