Cell Structures
Whats the difference between Prokaryotic and Eukaryotic cells?
Prokaryotic cells are unicellular organisms while Eukaryotic is multicellular.
What is diffusion?
Overall movement of particles from an are of higher concentration to low concentration
What do we call people that study ecology?
People who study ecology are called ecologist.
What is DNA?
Molecules that carry genetic information.
What is claim?
Plants need sunlight to grow.
What are the 3 principles of cell theory?
All living organisms are made of cells. All existing cells are produced by other living cells. The cell is the most basic unit of life.
What is osmosis?
The diffusion of water across a selectively permeable.
What does bio stand for in biosphere?
It stands for life.
What is Mitosis?
The process when one cell divides to create two genetically identical cells.
What is evidence?
In a simple experiment, scientists grew two groups of plants. One group was in the sunlight, and the other group was kept in a dark room. The plants in the sunlight grew much better than those in the dark. This shows that sunlight helps plants grow.
What's one part of the cell that the plant has but the animal doesn’t?
The plant cell has a cell wall the animal cell doesn't.
What is the difference between solvent and solute?
The solute is the substance that is being dissolved, and the solvent is the substance in which it is dissolved.
What is biosphere?
The biosphere is the portion of earth that has life.
What shape are chromosomes?
They are X-shaped.
What is evidence?
In another experiment, researchers placed plants in different amounts of sunlight—some got a lot, some got a little, and others got none at all. The plants with the most sunlight grew the tallest and healthiest, while the ones with no sunlight started to die and turn yellow.
What does the nucleus contain?
The nucleus contains DNA.
How would temperature effect diffusion?
As temperature increases molecules move faster increasing the process of diffusion.
What is commensalism
A relationship in which one organism benefits and the other does not.
What is metaphase?
The third phase in a cell cycle which is when the chromosomes duplicate and become sister chromatids.
What is reasoning?
Sunlight is used in photosynthesis to produce the energy plants need to grow.
Where are ribosomes made?
They are made in the nucleolus.
What does is mean to be selectively permeable?
When some substances are kept in while others are kept out.
What are the 4 main symbiotic relationships?
The 4 symbiotic relationships are mutualism, parasitism, commensalism, and competition.
What is a gene, and what does it have to do with DNA?
A gene is the physical and functional unit of heredity, and it is made up of DNA.
What is reasoning?
Sunlight is used in photosynthesis to produce the energy plants need to grow.
