How do you explain the differences in the apparent shapes and position of the nuclei in different cells?

How do you explain the differences in the apparent shapes and position of the nuclei in different cells?

Are nuclei visible in cyanobacterial cells? How do you explain the differences in the apparent shapes and positions of the nuclei in different cells? The nucleus is in different locations because it is free to move around and not attached to any point in a cell. What shapes are onion cells?

Why is the position of the nucleus different between the cells?

The differences are due to the direction and the place in which the slice is made. The nucleus of a plant cell is in the cytoplasm with the centre of the cell often occupied by the vacuole. The reason why nuclei appear in different parts of a cell section is for the same reason.

What is the position of the nucleus in a plant cell?

In an animal cell, the nucleus is located in the central region of the cell. In a plant cell, the nucleus is located more on the periphery due to the large water-filled vacuole in the center of the cell.

What is the shape of the nucleus in a plant cell?

Oftentimes in plant cells, the central vacuole expands with water to apply pressure to the cell walls. This pressure forces the nucleus into a more flattened, oblong shape.

How do the shape and body consistency differ between amoeba and paramecium?

An amoeba has no shape. It uses its pseudopod (makeshift-foot) to assist with its movement, by extending it out to the desired direction, then letting its body settle in it. While a paramecium has more of an oval-shape and uses cilia (tiny hairs) to help with movement. Hope this helps.

How do the shape and organelles differ between amoeba and paramecium and plant cells?

Amoeba body is more fluid; Paramecium body is rigid but somewhat flexible. How does shape and body consistency differ between Amoeba and Paramecium? Mitochondria, nuclei, and endoplasmic reticulum occur in plant cells. A Contractile vacuole and pellicle do not occur in plant cells.

What best describes the relationship between the nucleus and the cytoplasm?

Which of the following best describes the relationship between the nucleus and the cytoplasm? The nucleus is an organelle that is surrounded by the cytoplasm. The nucleus is the site of protein assembly.

What is the difference between the position of nucleus in plant and animal cell?

The nucleus is present in the plant cell and lies in one side of the cell. The nucleus is present in the animal cell also but lies in the centre of the cell.

What is the difference in position of nucleus in plant and animal cell Why is it so?

nucleus in animals is present at the center of cell where as in plants it is not in centre. It is because of vacuoles which is larger in size in plants and absent or small in animals.

How does the shape of the nucleus help it function?

The nuclear envelope is a double membrane that separates the nucleus from the cytoplasm. The nuclear envelope is perforated with numerous pores called nuclear pores. The envelope helps to maintain the shape of the nucleus and assists in regulating the flow of molecules into and out of the nucleus through nuclear pores.

What gives a nucleus its shape?

The cell nucleus is bound by a double membrane called the nuclear envelope. The nuclear envelope helps to maintain the shape of the nucleus. It is connected to the endoplasmic reticulum (ER) in such a way that the internal chamber of the nuclear envelope is continuous with the lumen, or inside, of the ER.

How do the amoeba and paramecium differ?

The key difference between amoeba and paramecium is that the amoeba moves using pseudopodia while the paramecium moves using cilia. Amoeba and paramecium are two very important unicellular eukaryotes.

Why do nuclei appear in different parts of a cell?

(The slice may, of course, not even go through the pea and many cells in a section appear to have no nucleus.) The reason why nuclei appear in different parts of a cell section is for the same reason. If you slice a salami sausage, you normally cut it to produce circular slices.

How does shape and body consistency differ between amoeba and Paramecium?

Amoeba body is more fluid; Paramecium body is rigid but somewhat flexible. How does shape and body consistency differ between Amoeba and Paramecium? Mitochondria, nuclei, and endoplasmic reticulum occur in plant cells.

Where is the nucleus of a plant cell?

The differences are due to the direction and the place in which the slice is made. The nucleus of a plant cell is in the cytoplasm with the centre of the cell often occupied by the vacuole. A section through a cell may show the nucleus at the side, or it might appear in the centre of the cell if the section was of the “edge” of a cell.

Are there mitochondria that do not occur in plant cells?

Mitochondria, nuclei, and endoplasmic reticulum occur in plant cells. A Contractile vacuole and pellicle do not occur in plant cells. What structures in Amoeba and Paramecium also occur in plant cells?
