Answer 1

Я уже ответила на подобный вопрос, но повторюсь:

 Одна из самых важных функций эпидермы - защита растений от неблагоприятных условий окружающей среды.
К функциям кожицы можно отнести и следующее:
- регуляция газообмена
- выделение наружу различный веществ
- участие в фотосинтезе
- поглощение Н2О и питательных веществ
И многое другое! Если что-то не понятно - обращайся :)

The Role of Epidermis in Plant Protection

The epidermis, also known as the outermost layer of the plant's tissue, plays a crucial role in protecting the plant from various external factors. It serves as a barrier against physical damage, pathogens, and excessive water loss. The epidermis is present in all aerial parts of the plant, including leaves, stems, and flowers.

Physical Protection: The epidermis acts as a physical barrier, preventing the entry of harmful microorganisms, insects, and other pests into the plant's tissues. It serves as the first line of defense against external threats.

Pathogen Defense: The epidermis contains specialized cells called guard cells, which are responsible for regulating the opening and closing of stomata. Stomata are tiny openings on the surface of leaves and stems that allow for gas exchange. The guard cells can close the stomata to prevent the entry of pathogens, such as bacteria and fungi, into the plant.

Water Regulation: The epidermis plays a crucial role in preventing excessive water loss from the plant. It is covered by a waxy layer called the cuticle, which reduces water evaporation. This cuticle layer helps the plant retain moisture and adapt to different environmental conditions.

Protection Against UV Radiation: The epidermis also provides protection against harmful ultraviolet (UV) radiation from the sun. It contains pigments, such as flavonoids, that absorb UV light and prevent damage to the underlying tissues.
