What is the difference between antheridia and archegonia?
Antheridia are male reproductive structures that produce sperm cells, while archegonia are female reproductive structures that house egg cells. Antheridia are typically smaller and simpler in structure compared to archegonia. Both structures are commonly found in plants like mosses and ferns.
Are archegonia haploid or diploid?
Archegonia are haploid structures found in plants. They are part of the female reproductive structure and are responsible for producing the egg cells.
Mosses grow from special cells called what?
Mosses grow from special cells called rhizomes. The rhizomes are the ones that will produce rhizoids which stems will grow from.
How are nutrients transported to the cells in a plant?
Nutrients are transported to the cells in a plant through the xylem and phloem. The xylem carries water and minerals from the roots to the rest of the plant, while the phloem transports sugars and organic compounds produced during photosynthesis to different parts of the plant.
Which waste product is picked up from cells by blood?
Carbon dioxide is the waste product that is picked up from cells by blood. It is transported to the lungs where it is expelled from the body during exhalation.
What is archegonia?
Archegonia are the female reproductive structures found in certain plants, particularly in bryophytes (like mosses) and some vascular plants (like ferns). They are typically flask-shaped and produce egg cells. In the life cycle of these plants, the archegonia play a crucial role in sexual reproduction by facilitating fertilization when sperm, produced by male structures, reaches the egg. After fertilization, the zygote develops into an embryo within the archegonia.
What is the difference between antheridia and archegonia?
Antheridia are male reproductive structures that produce sperm cells, while archegonia are female reproductive structures that house egg cells. Antheridia are typically smaller and simpler in structure compared to archegonia. Both structures are commonly found in plants like mosses and ferns.
What are moss egg cells produced by?
Moss egg cells are produced by the female reproductive organs called archegonia in moss plants. The archegonia are responsible for producing and releasing the egg cells, which are then fertilized by sperm cells to form a zygote.
Where are moss eggs cells produced?
archegonia
Are archegonia haploid or diploid?
Archegonia are haploid structures found in plants. They are part of the female reproductive structure and are responsible for producing the egg cells.
What is the function of archegonia?
Archegonia are the female reproductive structures found in certain plants, particularly in bryophytes and ferns. Their primary function is to produce and house the egg cells (ovules) during reproduction. Once fertilization occurs, the archegonia provide a protective environment for the developing embryo, facilitating its growth until it can establish itself as a new plant.
Structure that holds antheridia and archegonia in ferns?
The structure that holds antheridia and archegonia in ferns is called the gametophyte. It is a small, heart-shaped structure that develops on the underside of the fern frond. Antheridia produce sperm cells, while archegonia produce egg cells for sexual reproduction in ferns.
How are sperms transferred from the male to the female plantin mosses and in ferns?
In mosses, sperm is transferred from the male gametophyte to the female gametophyte via water, as sperm cells swim through moisture to reach the egg. In ferns, sperm is also motile and relies on water for movement; they swim from the male antheridia to the female archegonia during the process of fertilization. Both processes depend on water, highlighting the need for a moist environment for reproduction in these non-flowering plants.
Where are the moss egg cells produced?
Moss egg cells, also known as archegonia, are produced in the reproductive structures called gametangia, which are located at the tips of the gametophyte plant body. These gametangia develop on the female moss plants, and each gametangium contains an egg cell.
Food elements are transported by what cells?
Food elements are primarily transported by phloem cells in plants. Phloem is responsible for the movement of nutrients, particularly carbohydrates produced during photosynthesis, from the leaves to other parts of the plant. In addition to phloem, in animals, nutrients from digested food are transported by red blood cells and plasma through the circulatory system.
What are hormones transported to?
Hormones are transported to target cells, which are cells in another part of the body where the hormone will have an effect.
Mosses grow from special cells called what?
Mosses grow from special cells called rhizomes. The rhizomes are the ones that will produce rhizoids which stems will grow from.
