- Cell division is the process of cells separation into many cells.
- Cells are the building blocks of body.
- Chloroplast is the energy transformation center of cells.
- Centrioles are found in the nucleus of a cell.
- Both atoms and cells are made up of smaller parts including the nucleus.
- Nucleus center of holds all the supplies needed to make in the body.
- The differences between eukaryotic and prokaryotic cells are presence or absence of ribosomes.
- There is no cell division in plant cells but it occurs only in animal cells.
- The chromosome number is doubled in the Prophase of mitosis and halved in the Anaphase of mitosis.
- Mitosis and meiosis are function in an opposite and contrasting manner.
- Very large cell has a larger surface area to volume ratio than a very small cell.
- Animal cells get energy for its function by synthesis of their own food.
- Chromosomes are formed as a result of shrinkage and thickening of spindle fibers.
- The organelles such as mitochondria and chloroplasts dissolve and vanish during cell division and then are reformed.
- DNA replication occurs in prophase during the process of cell division.
- Inter phase is the resting phase of mitosis
