Thus, in angiosperms (flowering plants) and gymnosperms (plants with “naked seeds”), the male structures produce pollen (which contain sperm), and the female structures have one or more ovaries (which contain eggs known as ovules).

When it comes to growing cannabis, seeds can be male, female or hermaphrodites. Females produce the resin-secreting flower, and males make small sacs of pollen near the base of the leaves.

According to the myth, “male” bell peppers have three lobes and are more bitter, while “female” bell peppers have four or more lobes, have more seeds, and are sweeter to eat. ... The seeds are formed in each pepper after pollination, with those seeds then able to form new pepper plants.

What are three differences between seed plants and seedless plants? Seed plants produce seeds Unlike gametophytes of seedless plants, the gametophytes of seed plants do not live independently of the sporophyte The sperm of seedless plants need water to swim to the eggs of female gametophytes.

Most greenhouse cucumber plants produce both male and female flowers – it's easy to tell the difference as male flowers have simple stalks while female flowers have miniature fruits forming behind the petals.

They have a seed in their open scales that becomes a new tree when it gets pollen from a male cone. Male cones are a lot smaller than female cones and their scales aren't as open. Each scale in a male cone contains the pollen that can spread to a female cone to make a seed.

If what you've got is a handful of seeds, it's pretty much impossible to tell which ones are male or female. The only way true way to tell the plant's gender is to plant some seeds, then wait. After a period of several weeks, it will begin to pre-flower, or form a small bud in the crux of a branch.

As a monoecious plant, maize develops unisexual male and female flowers in physically separated parts of the plant. ... Initially, both inflorescences contain bisexual flowers. During the course of development, however, they become unisexual through abortion of gynoecia in the tassel flowers and stamens in the ear flowers.

Some plants are indeed only male or only female. Ginkgo, kiwi, cannabis, and willow all have individuals that make only pollen or only seeds. Botanically, they are known as dioecious plants, and their strategy ensures genetic outcrossing.

Plants that reproduce by seeds. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed. The seed protects the embryo and stores food for it.

Both autoflowering and photoperiod strains can be feminized. All it means is that a breeder modified a particular strain to produce only female plants. Technically speaking, the odds of a female emerging are 99.9%—that's still quite impressive!

When determining the sex of kiwi blooms, the female will also have bright white, well defined ovaries at the base of the flower, which, of course, the males lack. The ovaries, by the way, are the parts that develop into fruit. Male kiwi flowers have a brilliantly colored yellow center due to its pollen bearing anthers.

Feminized seeds produce only female plants, and when they germinate there will be few males among them if they are produced correctly. ... Feminized seeds are produced by inducing a normal female, not a hermaphrodite, to grow male flowers with viable pollen.

A female flower has a grape-sized swelling at its base; after pollination, the swelling increases in size and develops into fruit. A male flower has thin filaments called stamens at its center.

Male vs. Female Marijuana Plants – A Quick Rundown Female crops have pointed green calyxes that sprout a white and wispy pistil – a hair-like part of the plant that grows from the calyx. Male crops have round, green pollen sacs that enlarge and don't sprout a white, wispy pistil.

Watermelons have both male and female flowers on the same plant. It's easy to tell the difference because the male flowers have powdery pollen-filled anthers and the female flowers have an ovary below them that looks like a tiny watermelon (b/c it is).

Since Y is dominant, each case results in yellow seeds. If the plant has the YY genotype, all gametes would receive a Y, as that is all that is available. If the plant had the Yy genotype, then there are two possibilities: either a Y or a y. Only dominant alleles are possible from a homozygous dominant parent.
