sperm to sperms cells
Oolemma is the cell membrane that surrounds the oocyte, or egg cell. It plays a critical role in regulating the movement of substances in and out of the egg cell during fertilization and early development.
The zygote is the first cellular form of development in mammals. This results from the union of the sperm and egg cell.
The shape of a frog's egg cell is spherical in order to maximize surface area relative to volume, which allows for efficient nutrient uptake and waste removal during early development. This shape also aids in facilitating the fusion of sperm with the egg during fertilization.
The inactive stage of development is one where the insect grows but does not move. This is most common during the egg stage.
Water, nutrients, gases, and waste products are known to move through the egg membrane during the process of embryonic development. These materials are essential for the growth and survival of the developing embryo.

Oogenesis begins during fetal development, specifically during the development of the ovaries in the fetus. It is the process by which female gametes (egg cells) are produced in the ovaries.
Yes, egg cells are present in the ovaries of females at birth. These egg cells are already formed during fetal development and are released from the ovaries during ovulation later in life.
The uneven surface of a bumpy chicken egg is caused by the presence of pores on the eggshell, which are natural openings for air and moisture exchange during the egg's development.
The process in which a sperm enters an egg and triggers further development. We say fertilisation has occurred when we see the nucleus of the sperm together with the egg nucleus inside the egg cell under the microscope
During the process of embryonic development, you start as a single cell called a zygote, which is formed when a sperm fertilizes an egg.
The sperm fertilizes the egg and it begins to grow as an embryo. During the eight week of development it becomes recognizable as being human and is called a fetus.
The function of a starfish egg cell is to unite with a sperm cell during fertilization to form a new embryo. The egg cell contains the genetic information necessary for the development of the new organism.
Yes, it was a mistake, or Easter egg, in development.
This really depends on what you mean by "egg production". If you mean the actual development of the egg in the ovary, this begins during embryonic development (i.e. while the female baby is developing in utero). Human females are born with every egg (or ovum) that they will ever have. These eggs are held in a kind of "stasis" until puberty, when they fully mature during the menstrual cycle and are released from the follicle.
