Question

Кожица (эпидерма) защищает растение от

Answer 1

 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 :)

Answer 2

Эпидерма-кожица которая защищает внутренние части листа, регулирует газообмен и испарение воды.

Answer 3

The Role of the Epidermis in Plant Protection

The epidermis, or outermost layer of a plant, 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. Let's explore the different ways in which the epidermis protects the plant.

Physical Protection: The epidermis acts as a physical barrier, shielding the underlying tissues from mechanical damage, such as abrasion or impact. It provides structural support and prevents the entry of harmful substances into the plant.

Pathogen Defense: The epidermis plays a vital role in preventing the invasion of pathogens, such as bacteria and fungi. It acts as the first line of defense by producing a waxy cuticle, which makes it difficult for pathogens to penetrate the plant's tissues. Additionally, the epidermis may contain specialized cells, such as trichomes or hairs, that can deter or trap pathogens.

Water Regulation: The epidermis helps regulate water loss from the plant through a process called transpiration. It is covered by a waxy cuticle that reduces water evaporation from the plant's surface. The epidermal cells also control the opening and closing of stomata, tiny pores on the leaf surface, which further regulate water loss and gas exchange.

UV Protection: The epidermis provides protection against harmful ultraviolet (UV) radiation from the sun. The cuticle and epidermal cells contain pigments, such as flavonoids, that absorb or reflect UV light, preventing it from damaging the underlying tissues.

Environmental Adaptation: The epidermis can adapt to different environmental conditions. In some plants, the epidermal cells may develop specialized structures, such as sunken stomata or hairs, to reduce water loss in arid environments. In aquatic plants, the epidermis may have air-filled spaces that help with buoyancy and gas exchange.

In summary, the epidermis of a plant plays a crucial role in protecting the plant from physical damage, pathogens, excessive water loss, UV radiation, and adapting to different environmental conditions. It acts as a barrier and regulates various processes to ensure the plant's survival and well-being.
