science- cell division

what are the parts of the CELL THEORY?

1. everything is made of one or more cells. 2. cells carry out the functions needed to support life. 3. cells only come from other living cells.

a cutting taken from a plant grows into a new plant as the result of what process?

A cutting taken from a plant grows into a new plant as a result of regeneration( asexual reproduction)

in asexual reproduction, how many parent cells are necessary?

Asexual reproduction in most organisms involves one parent- going through mitosis(cell division)

what form or reproduction is budding? what type of organism does budding produce?

Budding produces an organism that is genetically identical (same DNA as parent) to the parent. Budding is asexual reproduction.

what occurs last to the nucleus in the division of a plant cell?

a cell plate forms to separate the two new daughter cell's nuclei and its cytoplasm and will form the new cell wall for both daughter cells.

when does a cell produce two genetically identical daughter cells?

a cell produces two genetically identical daughter cells when it under goes mitosis (division of the nucleus- DNA divides)

what is budding? give an example of budding.

budding is when an organism grows tiny buds or extensions from its body and those buds can break and form a new organism. ex: bread yeast reproduces by developing tiny extensions on their bodies.

what does cell division always result in?

cell division always results in the formation of two new daughter cells that are genetically identical to the parent cell and to each other

what happens to the cells in an adult human?

cells in an adult human divide so that the bod can grow and repair itself. the cell division process slows down but does not stop.

during what phase of the cell cycle do cells prepare for cell division?

cells prepare for cell division during interphase of the cell cycle.

how do cells share genetic material?

cells share genetic material when they divide during cell division creating two new daughter cells.

how do cells prepare for cell division?

during interphase the cell duplicates its DNA and grows to prepare itself for cell division.

what process begins the cell cycle?

interphase which is the longest part of the cell cycle.

list the following processes in the proper order: cytokinesis, interphase, and mitosis.

interphase,mitosis,cytokinesis

how do most multi-cellular organisms continue to grow and develop?

most multi-cellular organisms grow and develop because their cells continue to divide through cell-division

when does the cell cycle end?

the cell cycle ends when mitosis and cytokinesis are over

describe what happens during interphase.

the cell grows to about twice its original size. It goes through normal activities as it duplicates its DNA and prepares for cell division.

after cell division, mitosis and cytokinesis how many chromosomes are present in the daughter cells compared to the parent cell?

the two new daughter cells have the same number of chromosomes as the parent cell did before cell division.
