Answer: Angiosperms are the plants which produce flowers for sexual reproduction.
Explanation:
In the angiosperm life cycle the following events occur:
1. Seed germination: Under suitable condition inside the soil obtain water, oxygen and minerals the seed germinates and from the two precursors plumule from where the stem emerge and radicle from where the root emerges.
2. Mature plant with flower: The plant gets matured with the develop of root and shoot and from the shoot the bud originates which produces the flower.
3. Pollination: During the process of pollination a mature pollen grain is transferred towards the female reproductive structure typically the stigma receives the pollen grain.
3. Fertilization of pollen with egg in ovary: The pollen is the male gametophyte which develops in the anthers which are the male reproductive structure of the flower and the egg or ovule is the female gamete which develops inside the ovary or female gametophyte. The fusion of male gametes provided by the pollen grain with that of the ovule is called as fertilization.
4. Formation of fruit with seed: After the fertilization process the ovules develop into seed and the ovary into fruit.
5. Seed dispersal: The fruit gets detached from the plant and it may get rotten and dried the dried seeds disperse and may germinate in favorable conditions.
Sebaceous glands help in maintaining temperature homeostasis.
Sweat and sebum are both produced by the sebaceous glands. Each of these liquids serves a purpose in preserving equilibrium. Sweating helps the body expel minute amounts of metabolic waste while cooling the skin when it becomes hot.
Sebaceous glands are tiny oil-producing glands found in mammal skin. Typically linked to hair follicles, sebaceous glands secrete a fatty substance called sebum into the follicular duct, which subsequently travels to the skin's surface. With the exception of the palms of the hands and the soles of the feet, the glands are found all over the body, but they are most prevalent on the scalp and face.
