What else can I help you with?
Where are sex cells made?
Ovaries in females, testes in males.
What type of cells are known as gametes?
Gametes are specialized sex cells that are involved in sexual reproduction. In humans, gametes include sperm cells produced by males and egg cells produced by females. Gametes carry half the genetic information of a normal cell and fuse during fertilization to form a zygote.
What produces male reproductive cells?
Male reproductive cells, also known as sperm, are produced in the testes through a process called spermatogenesis. Specialized cells within the testes known as spermatogonia undergo a series of divisions and maturation steps to eventually form sperm cells.
In humans which cell is produced most directly by mitotic cell division?
Skin cells are most directly produced by mitotic cell division in humans. This is because the outer layer of our skin, known as the epidermis, is constantly renewing itself through cell division to replace old skin cells that are shed.
Where does the cell theory state that all cells come from?
The cell theory states that all cells come from pre-existing cells. This principle, known as the principle of biogenesis, was proposed by Rudolf Virchow in 1855, concluding that cells can only be produced by division of pre-existing cells.
Where are red cells produced and what is the process known as?
Red blood cells are produced in your red bone marrow. The process is known as erythropoiesis.
What is the process by which meristems are continually replenished?
One meristem cell undergoes cell division to separate into two cells. One cell remains meristematic, and the other is free to differentiate and contribute to the plant body. Through this process, meristems are continually replenished/constantly renewed.
What cells have irregular shapes.?
Bone marrow continually produces healthy cells in our marrow. Cells that are produced irregular are most commonly known as cancer.
What produced sperm cell?
Cells do not produce sperm. Spermatozoa, also known as sperm cells, are produced in the testes.
ADH is produced by cells within the?
ADH (antidiuretic hormone), also known as vasopressin, is produced by cells within the hypothalamus and released by the pituitary gland in response to changes in blood osmolality.
Where are sex cells made?
Ovaries in females, testes in males.
Why cant a cell in the brain be replaced?
there are some cells in the body that after the are produced once, they can no longer reproduce. These cells are known as cells in the quiescent stage. They are permanantly in G0 phase.
What creates sex cells and offspring?
Sex cells, also known as gametes, are created through a process called meiosis. In animals, male sex cells are called sperm, which are produced in the testes, while female sex cells, known as eggs or ova, are produced in the ovaries. When a sperm fertilizes an egg during sexual reproduction, it leads to the formation of offspring.
What elongation of root and stem forms what is known as?
The elongation of root and stem is known as primary growth. This process occurs at the tips of roots and stems, facilitated by the activity of apical meristems, which are regions of undifferentiated cells. Primary growth allows plants to increase in length, enabling them to access more nutrients, water, and light.
What cells produce pepsinogen and hcl?
Chief cells of the stomach (gastric glands in stomach have chief cells)
What type of cells are known as gametes?
Gametes are specialized sex cells that are involved in sexual reproduction. In humans, gametes include sperm cells produced by males and egg cells produced by females. Gametes carry half the genetic information of a normal cell and fuse during fertilization to form a zygote.
What kind of cells is produced during meiosis in the ovary?
germ cells
