100
The movement of particles from regions of higher density to regions of lower density.
What is DIFFUSION?
100
The process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food.
What is PHOTOSYNTHESIS?
100
The life cycle of a cell.
What is the cell cycle?
100
46 chromosomes or 23 pair of chromosomes
What is the number of chromosomes that humans have?
100
Before mitosis begins, chromosomes are copied. Each chromosome becomes two chromatids.
What is the INTERPHASE (Copying DNA)?
200
The diffusion of water through a semipermeable membrane. When particles move from areas of higher concentration to low is so important that is has a special name......
What is OSMOSIS?
200
The process by which cells use oxygen to produce energy from food and the breakdown of food without the use of oxygen.
What is CELLULAR RESPIRATION and FERMENTATION?
200
In a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA.
What is a CHROMOSOME?
200
A parent cell with 10 chromosomes will go through what process to produce new cells.
What is MITOSIS and CYTOKINESIS?
200
The nuclear membrane is dissolved. Paired chromatids align at the cell's equator.
What is the METAPHASE (Mitosis Phase 2)?
300
Only certain substances can pass through.
What is a membrane that is SEMIPERMEABLE?
300
The word respiration means "breathing," but cellular respiration is different from breathing. Breathing supplies the oxygen needed for cellular respiration. Breathing also removes carbon dioxide, which is a waste product of cellular respiration. Cellular respiration is a chemical process that occurs in cells.
What is the difference between CELLULAR RESPIRATION and BREATHING?
300
A form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size.
What is BINARY FISSION?
300
A nuclear membrane forms around each set of chromosomes and the chromosomes unwind. Mitosis is complete.
What is the TELOPHASE (Mitosis Phase 4)?
300
In cells that lack a cell wall, the cell pinches the cytoplasm in two. In cells that have a cell wall, a cell plate forms between the two new cells. This process takes place once mitosis is complete.
What is CYTOKINESIS?
400
If you place a red blood cell in pure water, water molecules would flood into the cells and cause them to burst.
Why would a red blood cell burst if you placed them in pure water?
400
Photosynthesis transfers the energy from the sun into glucose. During photosynthesis, cells use carbon dioxide to make glucose, and the cell release oxygen. During cellular respiration, cells use oxygen to break down glucose and release energy and carbon dioxide. Each process makes the materials needed for the other process to occur elsewhere.
What is the connection between PHOTOSYNTHESIS and CELLULAR RESPIRATION?
400
In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes.
What is MITOSIS?
400
Mitosis begins. Chromosomes condense from long strands into rodlike structures.
What is the PROPHASE (Mitosis Phase 1)?
400
When a plant cell divides, a cell plate forms and the cell splits into two cells. In a cell that does NOT have a cell wall ex. animal cell), the cell membrane pinches inward to form a groove, which eventually pinches all the way through the cell and two daughter cells form.
What is the difference between cytokinesis in an animal cell and cytokinesis in a plant cell?
500
Passive transport is the movement of substances across a cell membrane without the use of energy by the cell. Active transport is the movement of substances across the cell membrane that requires the cell to use energy.
What is the difference between passive and active transport?
500
Most of the energy that fuels life processes comes from here.
What is the sun?
500
Which of the following cells would form a cell plate during the cell cycle? a) a human cell b) a prokaryotic cell c) a plant cell d) All of the above
What is a plant cell?
500
The chromatids separate and move to opposite sides of the cell.
What is the ANAPHASE (Mitosis Phase 3)?
500
Chromosomes that have the SAME sequence of genes and the SAME structure.
What is HOMOLOGOUS CHROMOSOMES?
