Why do gymnosperms and angiosperms not need flagellate sperm?
Gymnosperms and Angiosperms do not need flagellated sperm because they have other meathods to get the sperm to the egg. In Gymnosperms, the pollen that contains the sperm lands on the inside of a female cone scale where the megaspore mother cell is located. Once it lands there, the pollen begin to dig in and form a pollen tube. While this is happening, the megapore mother cell undergoes meiosis to form four haploid cells (now in gametophyte stage). One of these cells becomes the megaspore, one becomes the endosperm mother cell, and the other two become the gametopyte that surrounds the egg. When the sperm finally reaches the egg, it forms a zygote still inside the gametophyte. This zygote becomes the embryo, which becomes the seed, and the gametophyte becomes the seed coat. In Angiosperms, pollinators take pollen from one flower to another where it gets attached to a stigma, and forms a tube to that egg.
What are glands where sperm is produced called?
The glands where sperm is produced are called testes or testicles. They are located in the scrotum, a pouch of skin located outside the body that helps regulate the temperature of the testes for sperm production.
What is the scientific name for gymnosperms plant?
The scientific name for gymnosperms is Gymnospermae.
Which generation is dominant in gymnosperms?
The dominant generation in gymnosperms is the sporophyte generation.
Where does sperm develop in the male reproductive system?
Sperm develops in the testes, which are located in the male reproductive system.
What gymnosperms structure are haploid?
In gymnosperms, the haploid structures are primarily the gametophytes, which develop from spores. Specifically, the male gametophyte is found within pollen grains, while the female gametophyte is located within the ovule. These gametophytes produce the gametes (sperm and egg cells) necessary for fertilization, completing the life cycle of gymnosperms.
What are some of the uses of gymnosperms?
Gymnosperm is a sperm coming from human cellulartube
What were the first plant that did not require water for transferring sperm to eggs?
Gymnosperms
What are similarities between gymnosperms and angiosperms?
The most common similarity is definitely SPERM!!
What were the first plants that did not require water for transferin sperm to eggs?
The first plants that evolved to not require water for transferring sperm to eggs were the gymnosperms, such as conifers and cycads. Gymnosperms produce seeds that are not enclosed in a fruit, allowing them to be dispersed without the need for water for reproduction. This adaptation allowed them to colonize drier environments and diversify during the Paleozoic era.
What is the tiny heart-shaped part of a fern that produces bote sperm and egg?
Gymnosperms and anginosperms both?
What are angiosperms eggs fertilized in?
Angiosperm eggs are fertilized in the ovule, which is a structure located within the ovary of the flower. The pollen tube delivers the sperm cell to the egg cell within the ovule, leading to fertilization and the formation of a seed.

Does Gymnosperm have seed?
no gymnosperms do NOT have sperm cells. They are actually "naked seeds"
What are some examples of cells that contain flagella?
Bacterial cells, spermatozoa i.e. human sperm cell, green algae, ferns, mosses and some gymnosperms.
What is spore of gymnosperm?
The spores of gymnosperms are reproductive structures produced in the sporophyte generation. These spores are released from specialized structures called sporangia and develop into male and female gametophytes that produce eggs and sperm for fertilization. Gymnosperms include plants like conifers, cycads, and ginkgoes.
Where is the genetic material in sperm located on a cow?
The genetic material in sperm is located in the Cattle thymus gland on a cow.
