Which cells form a thin layer on the outer surface of the roots?
An outer surface of the roots has a thin layer of cells is called EPIDERMIS.
What does the daughter cell get from the parent cell?
Cell division is the mechanism by which DNA is passed from one generation of cells to the next and ultimately, from parent organisms to their offspring. Although eukaryotes and prokaryotes both engage in cell division, they do so in different ways.
What is a spore formation?
Spore formation is a form of reproduction in which the reproductive bodies called the spores are present in a sac called the sporangia. Once these spores mature the sporangia burst and these matured spores reach different areas by air, wind and water.
Which of the following cells is formed by meiosis?
Meiosis produces our sex cells or gametes? (eggs in females and sperm in males).
What is the outer surface of any cell?
The outer surface of all animal cells is covered by a glycocalyx composed of oligosaccharides (glycans) of glycoproteins and glycolipids and a layer of secreted mucus particularly in the gastrointestinal, respiratory, and urogenital tracts. The biological roles of the glyco- calyx are diverse.
What tissues form the root?
The primary tissues of the root are, from outermost to innermost, the epidermis, the cortex, and the vascular cylinder. The epidermis is composed of thin-walled cells and is usually only one cell layer thick.
How is a parent cell created?
All cells arise from other cells through the process of cell division. Meiosis is a specialized form of cell division that produces reproductive cells, such as plant and fungal spores and sperm and egg cells. In general, this process involves a “parent” cell splitting into two or more “daughter” cells.
How do daughter cells form?
Daughter cells are cells that result from the division of a single parent cell. They are produced by the division processes of mitosis and meiosis. At the completion of the mitotic cell cycle, a single cell divides forming two daughter cells. A parent cell undergoing meiosis produces four daughter cells.
Where are spores formed?
sporangium
In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes.
What cell is formed after meiosis 1?
haploid daughter
However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
