Best answer: What is the advantage of male and female flowers borne on the same plant?

Male and female flowers borne in the same plant. When male and female are borne on the same plant, there is no need for cross-pollination and pollinating agents. In these plants (having bisexual flowers) self-pollination occurs.

When male and female flowers are borne on different plants?

The plants in which male and female flowers are borne on separate individual are referred to as dioecious plants, e.g., papaya, date palm.

Why male and female flowers of gymnosperms are borne on different Sporophylls of the same plant?

In gymnosperms, spores are produced in sporangia of sporophyll. The statement explains that a plant has two different sex organs for both male and female,the male part of the plant generates the male gametes whereas the female part generates the female gamete.

When both male and female flowers are present on the same plant then said to B?

Bisexual: each flower of each individual has both male and female structures, i.e. it combines both sexes in one structure. Flowers of this kind are called perfect, having both stamens and carpels. Other terms used for this condition are androgynous, hermaphroditic, monoclinous and synoecious.

What is a polygamous plant?

So, the polygamous plants are the flowering plants which have both unisexual (male, female) and bisexual flowers on the same plant. In other words, a plant may have both bisexual and male flowers or bisexual and female flowers. Some may have bisexual, male and female flowers.

Why male and female cone is produced on different plants in gymnosperms?

Gymnosperms produce both male and female cones, each making the gametes needed for fertilization; this makes them heterosporous. Megaspores made in cones develop into the female gametophytes inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores.

Why male and female cone is different in gymnosperms explain your answer with suitable example?

In gymnosperms, a leafy green sporophyte generates cones containing male and female gametophytes; female cones are bigger than male cones and are located higher up in the tree. A male cone contains microsporophylls where male gametophytes ( pollen ) are produced and are later carried by wind to female gametophytes.

Why do some plants have male and female flowers on separate plants?

Most flowering plants have what are known as “perfect flowers” – each flower contains both male and female parts. … They often have separate male and female flowers, which means they may end up pollinating themselves – and not getting the genetic benefits of mating with other plants.

The male plant frequently grows taller than its female counterpart and has thicker, sturdier stalks to support its weight. Male plants also have fewer leaves than female plants, which tend to be shorter and bushier.

Do male flowers have ovaries?

The “male” or pollen-bearing part is called the stamen, and is composed of the filament and the anther. The “female” or seed-bearing part is called the pistil, and is composed of the ovary, the stigma, and the style. A flower may have exclusively male parts, exclusively female parts, or commonly, both.
