Cell Division: Mitosis and Meiosis Quiz

Growing many plants from small pieces, like cells.

Cells dividing and living on.

DNA thread in cells; visible during cell division.

DNA part making proteins.

Codeine is a pain killer.

A cell with one set of chromosomes.

A cell with two sets of chromosomes.

Changes in a cell from one division to the next.

Non-dividing stage of cell cycle.

Very elongated in Interphase.

Nuclear division creating two identical nuclei.

Two diploid cells formed

Chromosomes become visible.

Spindle fibers begin to form.

Nuclear membrane breaks down.

Chromosomes line up in the center of the cell. Each chromosome has two fibers attached.

Fiber contracts and chromosomes are pulled to the opposite ends of the cell.

The cell begins to divide into two cells. New nuclear membranes form. Chromosomes elongate forming chromatids.

The final step of cell division where the original cell divides to form two cells. The two resulting daughter cells contain the same number of identical chromosomes.

A process of cell division that results in two identical daughter cells.

Four main types: epithelial, connective, muscular, and nervous.

Four main types: meristematic, dermal, ground, and vascular.

Growing cells in a controlled environment outside the organism.

Growth of cells in an artificial environment, outside the organism.

Large vessels used for growing cells in tissue culture.

A group of diseases where cells divide uncontrollably and invade other tissues.

A non-cancerous tumor that doesn't spread to other tissues.

A cancerous tumor that can invade other tissues.

The spread of cancer cells from one part of the body to another.

A substance that causes cancer.

A cell that contains only one set of chromosomes.

Meiosis has two main functions: - Sexual reproduction: It produces gametes (sperm and egg) that combine to form a new organism. - Genetic variation: The shuffling of genes during meiosis increases the genetic diversity within offspring.

The first stage of meiosis, where chromosomes condense, pair up, and exchange genetic material (crossing over).

Cancer cells lose control over the rate and frequency of mitosis, leading to uncontrolled cell division and growth.

Lipids are a broad category encompassing fats and oils, which differ based on their state at room temperature.

Triglycerides are crucial for energy storage within the body.

Phospholipids are essential components of all cell membranes.

Phospholipids have a hydrophilic head, attracted to water, and hydrophobic tails, repelled by water.

Phospholipids arrange in a two-layered structure with their heads facing outwards and tails inwards.

The movement of molecules from an area of high concentration to an area of low concentration, without requiring energy.

A membrane that allows some molecules to pass through but blocks others.

A region with a lot of water molecules, meaning fewer dissolved substances (like sugar or salt).

A region with relatively fewer water molecules, meaning a higher concentration of dissolved substances (like sugar or salt).

Water moves out of the cell due to osmosis, leading to cell shrinking and potential death.

Water moves into the cell due to osmosis, resulting in swelling and potential bursting.

Water moves out of the cell, causing it to shrink. This process is called plasmolysis and can lead to wilting.

The process where the cell membrane pulls away from the cell wall in plant cells due to water loss.

The movement of water across a semi-permeable membrane in plant cells. This movement is influenced by the concentration of solutes inside and outside the cell, affecting the cell's water content and potentially leading to wilting or plasmolysis.
