Where sperm form in seed plants?
Sperm cells in seed plants are typically formed within the pollen grains, which are produced in the male reproductive structures of the plant (anther). When the pollen grain reaches the female reproductive structure (ovule) of the plant, the sperm cells are released and fertilization occurs.
What scientist first determined that all plants are composed of cells?
Theodor Schwann, a German physiologist, was the first scientist to determine that all plants, as well as animals, are composed of cells. This discovery was made in the early 19th century and formed part of the cell theory that revolutionized biology.
What is procallus?
Procallus is a structure that develops during the early stages of wound healing in plants. It is formed by undifferentiated cells that later differentiate into specific types of cells required for tissue repair and regeneration. The procallus helps to seal the wound and initiate the healing process in plants.
How are new plants formed?
New plants can be formed through sexual reproduction, where male and female reproductive cells join to create a seed. They can also be formed through asexual reproduction, where a new plant grows from a vegetative part of the parent plant, such as a stem or leaf cutting. Additionally, some plants can produce new plants through specialized structures like bulbs, rhizomes, or tubers.
Which cell helps in gas exchange in plants?
The main cell responsible for gas exchange in plants is the stomatal cell. Stomata are small openings on the surface of leaves and stems that are formed by two guard cells. The stomatal cells regulate the exchange of gases, such as carbon dioxide and oxygen, in and out of the plant through these openings.
Where are the male and female sex cells formed in plants?
male sex cells are formed in anther and female sex cells in the ovary
How is the dermis formed?
The division of the somatic cells (epithelial cells) in animal tissues/collenchyma cells in plants.
Where are haploid cells formed?
In the ovaries/testes for animals In the ovaries/anther for plants
What new cell is formed from meiosis in plants?
The process of meiosis produces pronography, also called sexual perversion.
Define mitosis how does differ in plants and animals?
It is the process of cell division taking place in somatic cells where two daughter cells are formed which have the same chromosome number as the mother cell and which are identical to the mother cell. It differs in plants and animals: Animals; A centriole formed at the poles. Plants: no centriole Animals: An incision develops between the two cells in the telophase Plants: A cross wall develops between the two cells in the telophase
Do plants have germ cells?
Plants do not have germ cells in the same way animals do. Plants reproduce through gametes, which are formed in specialized structures like pollen and ovules. These gametes are produced directly from cells in the reproductive organs of plants, rather than from separate germ cells.
Where are cells formed?
Cells are formed through the division of other cells.
How do cells formed?
New cells are created by division; an existing cell divides into two 'daughter cells'. Tissue growth and regeneration in plants and animals, and procreation in unicellular organisms (such as bacteria) are achieved this way.
Where sperm form in seed plants?
Sperm cells in seed plants are typically formed within the pollen grains, which are produced in the male reproductive structures of the plant (anther). When the pollen grain reaches the female reproductive structure (ovule) of the plant, the sperm cells are released and fertilization occurs.
What are cells formed during mitosis called?
Cells formed during mitosis are called daughter cells. These cells are genetically identical to the parent cell from which they were formed.
Blood cells are formed from what?
Blood cells are formed from haematopoietic stem cells by the process of haematopoiesis.
When is cytokenisis complete?
In both plants and animals, cytokinesis occurs in the last stage of cell division. It brings about the separation of a cell into two daughter cells.
