Which grows at a faster rate, surface area or volume? Why?
Volume increases faster because it is 3-Dimensional and surface area is only 2-Dimensional
This problem occurs when a cell grows too large for the fixed amount of DNA that controls its activities.
This problem happens to cells that become too big because the ratio of surface area to volume becomes too small.
The process occurs before a cell grows too large.
2 of these are produced when 1 cell divides.
These are the 3 steps of the cell cycle.
Interphase, Mitosis and Cytokinesis
These are the TWO steps in cell division.
Mitosis and Cytokinesis
These are the 3 parts of Interphase, in order.
G1, S Phase, and G2
This is the division of just the nucleus.
These are made of DNA and carry genetic information.
This is what a "replicated" chromosome is composed of.
TWO sister chromatids
This is the connection point where 2 sister chromatids are connected.
This is a period of growth, replication and activity that happens between cell divisions.
The cell grows larger during this first part of interphase. New proteins and organelles are also produced.
DNA replication and synthesis of new chromosomes occur in this part of interphase.
The cell prepares for cell division by producing organelles like centrioles.
These are the 4 phases of mitosis in order
Prophase Metaphase Anaphase Telophase (P-M-A-T)
These are the events of Prophase
1. The nucleus dissolves & replicated chromosomes become visible. 2. Centrioles start to move to opposite sides. 3. Spindle fibers start to form
This is what happens in Metaphase
Replicated chromosomes line up in the Middle of the cell between centrioles. Each is connected to a spindle fiber.
This is what happens in Anaphase
Sister chromatids of replicated chromosomes are pulled Apart
This is what happens in Telophase
Two nuclei form around opposite groups of chromatids in a single cell. Cytokinesis also begins here.
This is how many nuclei are present in one cell when MITOSIS is complete.
These are the only 2 phases of mitosis where replicated chromosomes are seen.
Prophase and Metaphase
This is the job of spindle fibers
To organize chromosomes and pull sister chromatids apart
This process occurs after mitosis and causes the rest of the cell to divide.
These type of cells carry out cytokinesis by "pinching in" (forming cleavage furrows) until they divide.
Because a plant cell has this, it cannot pinch in during cytokinesis.
This forms between 2 plant cells when they undergo cytokinesis.
If a parent cell has 46 chromosomes, how many chromosomes will be found in each of the daughter cells after cytokinesis is complete?
This is the formula for calculating volume.
L x W x H
This is the unit in which volume is measured.
This is the formula for calculating the surface area of a cube.
6 (L x W)
This is the unit in which surface area is measured.
During which phase of mitosis do chromosomes become visible?
What kind of cells undergo the cell cycle?
Somatic (body) cells undergo the cell cycle.
