The plant life cycle has
mitosis occurring in spores
, produced by meiosis, that germinate into the gametophyte phase. Gametophyte size ranges from three cells (in pollen) to several million (in a “lower plant” such as moss).
Do plant cells do mitosis?
Most plants continue to grow as long as they live. They grow through a
combination of cell growth and cell division
(mitosis). The key to plant growth is meristem, a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate.
Do plants replicate cells by mitosis?
When
plants reproduce asexually
, they use mitosis to produce offspring that are genetically identical to the parent plant. The advantage of asexual reproduction is that it allows successful organisms to reproduce quickly.
What is the role of mitosis in plants?
Explanation: The mitosis cell division helps
in vegetative growth
in plants. It also helps in healing of wounds.
Do animals and plants replicate cells by mitosis?
When plants and animals
reproduce their cells asexually
, the process is known as mitosis. … Plants have both a cell membrane and a cell wall, whereas animal cells have no cell wall. Animals also have cell centrioles, but higher plants don’t.
Do plant cells replicate their DNA?
DNA replication
in plant cells occurs in three basic steps, each catalyzed by at least one enzyme. First, the two original, or parental, DNA strands of the double helix unwind and separate. Then each parental strand is used as a template for the formation of a new daughter strand.
Do animals use mitosis?
Animal cells, like human cells, use
mitosis to grow larger cells
, replace damaged cells and repair injured tissue. Mitosis of an animal cell is an asexual reproductive process that produces two exact copies of a cell.
What are examples of mitosis?
Mitosis is the process of dividing a cell and its nucleus into two cells which each have their own nucleus. An example of mitosis is
the way the skin cells covering a child’s body all multiply while they are growing
.
What is the role of mitosis in animals?
In the case of multicellular organisms, mitosis helps in growth and repair by producing more number of identical cells. For example plants, animals depend on cell division
for their growth by addition of new cells
. … Mitosis refers to the splitting of chromosomes in the eukaryotic cells during the cell division process.
How does mitosis happen?
Mitosis is the process of nuclear division, which occurs just prior to cell division, or cytokinesis. During this multistep process,
cell chromosomes condense and the spindle assembles
. … Each set of chromosomes is then surrounded by a nuclear membrane, and the parent cell splits into two complete daughter cells.
What are the major differences between mitosis in animal cells and mitosis in plant cells?
| Animal cell Mitosis Plant cell Mitosis | A furrow is formed between two daughter cells. A solid middle lamella develops in between the two daughter cells for permanent adhesion. | It occurs in bone marrow and many epithelia. It is found in meristems. |

How is plant mitosis different from animals?
Explanation: The most important and observable difference in the plant animal cells mitosis is
the cytokinesis
. In plants a new cell plate is formed between the daughter cells for the future cell wall, while in animal cells the cell membrane constricts to separates the parent cell into daughter cells.
What animals use mitosis?
Some organisms use mitosis to replace body parts. For example
starfish
replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring. The process is known as budding.
Where does DNA replication occur in plants?
DNA replication occurs in
the cytoplasm of prokaryotes and in the nucleus of eukaryotes
. Regardless of where DNA replication occurs, the basic process is the same.
Do plant cells make daughter cells?
In plant cells,
a new cell wall must form between the daughter cells
. During interphase, the Golgi apparatus accumulates enzymes, structural proteins, and glucose molecules prior to breaking into vesicles and dispersing throughout the dividing cell.
How fast do plant cells divide?
Only a few types of eukaryotic cells can grow and divide as quickly as bacteria. Most growing plant and animal cells take
10 – 20 hours to double in
number, and some duplicate at a much slower rate.
