How does a centrosome know when it has found the center of the cell?
AT some point the initial sheet of tubulin curls into a tube to form the microtubule.
How does a centrosome “know” when it has found the center of the cell.
When all the oppositely directed microtubules emanating from a centrosome are the same length, the centrosome will be in the center of the cell..
What is a good analogy for nucleolus?
An analogy for the nucleolus is that the nucleolus is like a building materials manufacturer.
Why centrosome is not present in plant cell?
in plant cells microtubules are made by the Golgi bodies. Animal cells are much evolved than plant cells that’s why they have centrioles . Spindle formation is very much different in plant cells than in animal cells due to the absence of centrioles .
What can you compare Centrioles to?
Analogy: The centrioles of a cell can be compared to a dresser because a dresser keeps our clothes organized just as the centrioles organize cell division. Also asked, what everyday object is like a endoplasmic reticulum? Golgi Apparatus – Packing Things Up The Golgi apparatus or Golgi complex is found in most cells.
What part of a school is like a Centriole?
Endoplasmic Reticulum/ Lysosomes Just like Centrioles control the microtubules of the cytoplasm during cell division. The Endoplasmic Reticulum would be like the buses, because they carry students to school, and they can help transport things for the school.
How a cell is like a school?
in or out. The Cell Wall is like the beams in a school because it provides the school support. The Chloroplast is like the cafeteria in a school because it is where the students in a school get their energy. The Large Central Vacuole is like a swimming pool because it stores water for the swim team.
What can a mitochondria be compared to in a school?
Much like a boiler room providing energy to the school, the mitochondria provides energy to the cell. Ribosomes make proteins, and teach them, like how teachers teach students.
Why centrosome is absent in nerve cell?
Why are there no centrosomes in nervous cells? Dear Anonymous: The reason for this absence is that as soon as a cell becomes nervous — for whatever reason — the stress induced by this makes the centrosome disintegrate, and quickly disappear in a lysosomatic feeding frenzy …
Do plant cells have a centrosome?
While both animal and plant cells have microtubule organizing centers (MTOCs), animal cells also have centrioles associated with the MTOC: a complex called the centrosome. Animal cells each have a centrosome and lysosomes, whereas plant cells do not.
Do plant cells have spindle fibers?
Brief About Formation of Spindle Fibres in Plant Cells Plant cells lack centrioles but still, they are capable to form a mitotic spindle from the centrosome area of the cell located just exterior to the nuclear envelope.

What’s a good analogy for mitochondria?
Mitochondria are like the human digestive system because the digestive system breaks down food to supply the body with energy like the mitochondria breaks down food to supply the cell with energy.
How a cell is like a house?
Cell organelle. A cell is like a house. While the nucleus is the control center of the cell, people control everything inside the house. The Golgi apparatus packages/delivers proteins.
What is a good analogy for the Centriole?
A centriole helps organize the cell when it is divided. A centriole is like a secretary because they organize things.
What happens if centrosome is missing?
Centrosomes are not needed for the mitosis to happen. When the centrosomes are irradiated by a laser, mitosis proceeds with a normal spindle. In the absence of the centrosome, the microtubules of the spindle are focused to form a bipolar spindle. Many cells can completely undergo interphase without centrosomes.
Where is the centrosome found?
The centrosome is positioned in the cytoplasm outside the nucleus but often near to it. A single centriole is also to be found at the basal end of cilia and flagella.
In which cell Centriole is absent?
Centrioles are not present in all eukaryotes; for example, they are absent from conifers (pinophyta), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and ginkgo.
Do plants have lysosomes?
Lysosomes are membrane bounded organelles found in animal and plant cells. They vary in shape, size and number per cell and appear to operate with slight differences in cells of yeast, higher plants and mammals. Lysosomes contribute to a dismantling and re-cycling facility.
What makes a centrosome?
Centrosomes are organelles which serve as the main microtubule organizing centers for animal cells. Centrosomes are made of from arrangement of two barrel-shaped clusters of microtubules, called “centrioles,” and a complex of proteins that help additional microtubules to form.
What does a centrosome function like?
A centrosome is a cellular structure involved in the process of cell division. Before cell division, the centrosome duplicates and then, as division begins, the two centrosomes move to opposite ends of the cell.
What do plant cells have instead of centrioles?
Unlike animal cells, where microtubules are nucleated at discrete centriole-containing centrosomes, plant cells produce a bewildering assortment of microtubule arrays in the absence of centrosomes.
