Stomata
What else can I help you with?
Where on the plant are the stomata found?
Stomata are pores in the leaf's epidermis, or outer surface. They are used to regulate the outflow of water vapour and oxygen from the plant leaves as well as the inflow of carbon dioxide into the leaves. Stomata are normally found on the underside of the leaves (protected from direct sun and exposure to wind).
Where are the pores of plants found?
The pores of plants, called stomata, are typically found on the surfaces of leaves and stems. They regulate gas exchange by allowing carbon dioxide to enter for photosynthesis while releasing oxygen and water vapor. Stomata are essential for the plant's growth and survival.
Do humans have stomata?
No, humans do not have stomata. Stomata are microscopic pores found on the surface of plant leaves and stems that are used for gas exchange and transpiration. Humans have lungs for gas exchange and do not require stomata for this purpose.
The oblong support cells in young green stems or leaf stalks are?
The oblong support cells in young green stems or leaf stalks are collenchyma cells. They provide structural support to the plant and have thickened cell walls, especially at the corners where they join. Collenchyma cells are found just beneath the epidermis in areas that need flexibility and mechanical support.
In older woody plants the epidermis of the stem is replaced by what tissue?
In older woody plants, the epidermis of the stem is replaced by periderm, which includes tissues such as cork cambium, cork cells, and phelloderm. Periderm helps protect the stem and replaces the functions of the epidermis as the plant matures and its stems thicken.
Outermost layer of cells that covers roots stems leaves and flower parts?
The Epidermis
Where does air and water vapor cross the epidermis at?
Air and water vapor enter and exit through the stomata, tiny pores found on the surface of leaves, stems, and other plant organs. These openings are surrounded by specialized cells that can open and close to regulate gas exchange and water loss.
What is the layer inside the epidermis of root and stems that stores food?
cortex
Where on the plant are the stomata found?
Stomata are pores in the leaf's epidermis, or outer surface. They are used to regulate the outflow of water vapour and oxygen from the plant leaves as well as the inflow of carbon dioxide into the leaves. Stomata are normally found on the underside of the leaves (protected from direct sun and exposure to wind).
What is the layer of cells that covers roots stems leaves and flower parts?
epidermis
What are the brathing pores of stems called?
The breathing pores of stems are called stomata. Stomata are small openings located on the surface of plant leaves and stems that allow for gas exchange, including the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor.
Where are the pores of plants found?
The pores of plants, called stomata, are typically found on the surfaces of leaves and stems. They regulate gas exchange by allowing carbon dioxide to enter for photosynthesis while releasing oxygen and water vapor. Stomata are essential for the plant's growth and survival.
Outer most layer of cells that covers roots stems leaves and flower parts?
The outermost layer of cells that covers roots, stems, leaves, and flower parts is called the epidermis. The epidermis helps protect the plant from water loss, pathogens, and physical damage. It also plays a role in gas exchange and nutrient absorption.
Where are the plant epidermal cells found?
Plant epidermal cells are found on the outermost layer of plant tissue, covering the surfaces of leaves, stems, flowers, and roots. They serve various functions such as protection, gas exchange, and absorption of water and nutrients.
How do monocot and dicot stems differ in location?
Monocot stems are typically found in plants with parallel venation, while dicot stems are found in plants with reticulate venation. Monocot stems are usually found in the stems of grasses and palms, whereas dicot stems are found in a wide range of flowering plants.
Where are stoma usually found?
Stomata are usually found on the surface of plant leaves, stems, and other plant organs. They are tiny, specialized pores that allow for gas exchange, including the uptake of carbon dioxide and release of oxygen during photosynthesis.
Where are the protective tissues found in plant body?
Protective tissues in plant bodies are typically found in the epidermis, which is the outermost layer of cells. The epidermis is responsible for protecting the plant from physical damage, pathogens, and water loss. In woody plants, the outermost layer of the stem and roots is covered by a thick layer of protective tissue called the periderm, which replaces the epidermis in older parts of the plant.
