What organelle is sructure involved in mitosis in animal cell only?
The organelle involved in mitosis in animal cells is the centrosome. It contains a pair of centrioles that play a crucial role in organizing the spindle fibers necessary for chromosome separation during cell division. Unlike plant cells, which do not have centrioles, animal cells rely on centrosomes to ensure proper mitotic spindle formation. This structure is essential for the accurate distribution of chromosomes to the daughter cells.
What is one difference between the animal and plant cell?
One major difference between animal and plant cells is the presence of a cell wall in plant cells but not in animal cells. The cell wall provides structural support and protection in plant cells, while animal cells rely on other structures for support.
Which cell has a stronger outer covering - a plant cell or an animal cell?
A plant cell has a stronger outer covering compared to an animal cell. This is because plant cells have a rigid cell wall made of cellulose that provides structural support and protection, whereas animal cells do not have a cell wall and rely on a flexible cell membrane for structural integrity.
Pseudopod in plant cells?
A pseudopod is a temporary protrusion of the cell membrane in some protozoa and amoeboid cells for movement and feeding. It is not typically found in plant cells, which have a rigid cell wall that provides structural support and protection. Plant cells primarily rely on structures like flagella and cilia for movement.
How organelles of a cell relate to the community?
Organelles can be compared to different components of a community. For example, the nucleus is like the government, regulating and controlling the cell's activities. Mitochondria are like power plants, generating energy for the cell. The endoplasmic reticulum is like a transportation system, moving materials around the cell. Just as a community relies on different organizations for its functioning, cells rely on various organelles to carry out their specialized functions.
Do chloroplasts have a cell wall?
Chloroplasts do not have a cell wall. They are membrane-bound organelles found in plant cells and some algae, surrounded by an inner and outer membrane. The function of chloroplasts is to conduct photosynthesis, converting light energy into chemical energy, but they rely on the plant cell's cell wall for structural support.
Why are animal cells flexible whereas plant cell are rigid?
Plant cells have a rigid cell wall made of cellulose that provides structural support and rigidity, whereas animal cells do not have a cell wall and rely on other structural components like the cytoskeleton for support. This difference in cell wall composition is what makes plant cells rigid and animal cells flexible.
In plants that do not have tubes does the food travel in water around the outside of the plant or from cell to cell?
In plants that do not have tubes, like non-vascular plants, food and water are transported from cell to cell through a process known as simple diffusion. This movement occurs within the plant tissues and does not rely on specialized structures like xylem or phloem.
Is a virus smaller than an organelle?
Yes, viruses are typically smaller than organelles. Viruses are simple infectious agents that rely on a host cell to multiply, while organelles are complex structures within cells that carry out specific functions.
Which plant does not have special tissues to deliver food and water to its cell?
Live
What structures do dividing plant cells lack?
Dividing plant cells lack centrioles, which are organelles involved in organizing and segregating chromosomes during cell division. Plant cells instead rely on the formation of a preprophase band to assist in the orientation of the cell division plane.
Cells without cell wall is called as?
Cells without a cell wall are typically found in animals and are called animal cells. These cells rely on other structures like the plasma membrane for support and protection, instead of a rigid cell wall.
