Sexual Reproduction (Plants) The female gametes are found in the ovule. The ovules are made in the ovaries. In the case of some flowers, they will have nectaries and bright petals to attract insects into the flower. In other flowers pollen may be transferred by the wind or water. Thursday...

Sexual Reproduction in Plants Many plants use sexual reproduction through cones or flowers. Male reproductive cells are formed from the pollen of plants and the egg cells are located in cones or flowers. Pollination In conifers and flowering plants, male reproductive cells (pollen) fertilize eggs (...

Most of the evolved organisms on the planet, like plants and animals and various multicellular organisms, display sexual reproduction. This is often considered the superior method of reproduction because of variation and evolution that occurs. Let us dis
The cross-pollinated plants are seen to adopt several devices for the success of cross-pollination. Some of-these adaptations are; 1. Uni-sexuality or Dicliny: Often uni-sexuality is of great help in the success of cross-pollination. Plants bearing unisexual flowers are dioecious (e.g. Can...

Sexual reproduction is an essential process for generating a genetic variety in the next generation. However, most flowering plants and hermaphrodit...

Germination and Birth Whereas a vertebrate animal begins its life through exiting the mother's womb—either as an egg that must further develop and hatch, or as a newborn individual — in plants the new plant is "born" by germinating from the seed. In plants and animals, part of the mat...
