what is the difference between spores and pollen grains?

Spores are used by groups of ancient plants and fungi in one stage of their reproduction. ... Neither of these groups of plants produces flowers. Pollen is used by flowering plants to fertilize seeds. Fertilized seeds grow into adult plants, not intermediate gametophytes.

The main difference between pollination and fertilization is that pollination is the deposition of pollen grains from the anther to a stigma of a flower whereas fertilization is the fusion of the haploid gametes, forming a diploid zygote.

As nouns the difference between grain and granule is that grain is (uncountable) the harvested seeds of various grass food crops eg: wheat, corn, barley or grain can be a branch of a tree; a stalk or stem of a plant while granule is a tiny grain, a small particle.

What is the difference between how gymnosperms and angiosperms manifest their heterosporus nature? Gymnosperms don't have flowers so they manifest this nature in pollen grains on things like cones. Angiosperms have flowers and the flowers produce the pollen.

Plants that reproduce by spores Ferns, mosses, liverworts and green algae are all plants that have spores.

Bacterial spores are meant for survival in stressful conditions and are not for reproduction, like fungi spores are. The actual living cell, called the vegetative cell, produces a protective layer (spore) around its DNA until favorable conditions return.

Plants and Reproduction Non-vascular plants reproduce through spores. ... Flowers are the most evolved reproductive system in the plant world, with separate male and female organs, however a flower is only part of a plant and does not have an independent life of it's own.

There are many more angiosperms than gymnosperms. What is the difference between a Sporophyte and a Gametophyte? Sporophyte phase produces spores, while gametophyte phase produces gametes (egg and sperms). Therefore, sporophyte phase is asexual, while gametophyte phase is sexual.

A sporophyte is a reproductive structure while a gametophyte is not. A sporophyte undergoes sexual reproduction while a gametophyte undergoes asexual reproduction. A sporophyte is part of the diploid phase while a gametophyte is part of the haploid phase of the plant life cycle.

Most are haploid, but some can be diploid. Spores are stored in cases (asci), which release clouds of spore smoke. Nuclear fusion and meiosis take place within the ascus. Ascomycota are heterotrophic, obtaining nutrients from both dead or living organisms.

-They are haploid. They contain chromosomal tetrads. What is the main difference between oogenesis and spermatogenesis in terms of meiosis? -Oogenesis produces three polar bodies, while spermatogenesis produces only one.

Difference Between Human Sperm and Ovum. Sperm is the male gamete, produced in the testis of a male, while Ovum is the female gamete, produced in the ovary of a female. Ovum, also known as egg cell and is said to be the largest cell in the female body. On the contrary Sperm cells is the smallest cell in the male body.

Microspores are land plant spores that develop into male gametophytes, whereas megaspores develop into female gametophytes. ... Microspores are haploid, and are produced from diploid microsporocytes by meiosis.

Both dinoflagellates and diatoms reproduce using photosynthesis and they both also produce significant amounts of new organisms every year. A difference between them is their physical appearance. Diatom cells are encased in a “glass like” shell, whereas dinoflagellates have a shell made of cellulose.

Spore: A spore is a dormant, reproductive cell with a thick cell wall, which is highly resistant to unfavorable environmental conditions. Vegetative Cell: A vegetative cell is any cell of the body except the cells that participate in the production of gametes.

In essence, they're two variations of the same thing; hashish. Pollen is usually the softer or crumblier stuff whereas hash is a generic usually the name given to the rock hard stuff I like to bake with.

Here is a simple explanation of the difference. Mushrooms are the beautiful, delicate, lumpy, bumpy 'fruiting body' we see growing out of the ground or wood-they are the reproductive structures of fungi. Fungi is the entire organism. ... Therefore, all mushrooms are also fungi, but not all fungi produce mushrooms.
