The ovule of an angiosperm, which will eventually become a seed, is surrounded by integuments. They are layers of protective sporophytic tissue that eventually develop into the seed coat.

What do conifers produce?

Conifers produce seeds that are enclosed in an integument and born on cones. The integument is a thin layer of cells. Conifers do not produce flowers but in early spring, they produce flower-like structures.


What happens if your skin is damaged by a cut?

You would get sick rather quickly and very likely die. This is what happens in animals that get burned. The reasons why follow. The integumentary system is commonly referred to as your skin. In mammals this is the outermost layer of tissues, including hair and nails, that protects the body from the external environment. In most animals the internal and external environments are very different. For example, mammals have a moist and warm internal environment and must maintain this to survive. Without the integument, moisture is rapidly lost and body temperature will equilibrate (fall) to match the local environment and you have not protection from infection. The integument is a critical organ to maintain homeostasis. In lower organisms such as worms and insects, it can function as a gas exchanger (a primitive 'lung'); it also secretes waste products such as CO2, excessive water, garlic and urea. In all organisms it functions as a barrier, preventing pathogens getting in and causing disease and infection. It can act as a sensor (or receptor) of pressure and pain, The integument also produces products (antimicrobials) that kill pathogens and, ironically, can simultaneously feed the commensal bacteria and fungi that live symbiotically on the integument and help to prevent pathogens establishing a colony. In many animals the integument senses external temperature and pressure (through receptors contained within its various tissue structures. It further protects the bodies internal organs from damage fromphysical impacts. Another function of the integument is to provide a structure for many tissues that manufacture products that benefit the animal. Most tissues cannot function without a well defined structure. The integument provides such a structure by resisting the collapse of these tissues. In short, while the skeleton is used to hang organs from, the integument is used to hold them toghether and stop them from flapping around.


What function do goosebumps play in your integument?

Goosebumps are caused by the contraction of tiny muscles called arrector pili muscles attached to hair follicles. In animals, this response can help trap air to provide insulation or make the animal appear larger to predators. In humans, goosebumps are a vestigial response that has lost its original function but can be triggered by emotions or cold temperatures.


What are some function of the integument?

The integumentary system functions to protect the body against external factors, such as pathogens and UV radiation. It also helps regulate body temperature through sweating and shivering. Additionally, the integumentary system houses sensory receptors that detect stimuli such as touch, pressure, and temperature.


Which part of the ovule is the testa and tegmen developed?

The testa is the outer seed coat that develops from the integuments of the ovule, while the tegmen is the inner seed coat that also originates from the integuments but lies closer to the seed.
