Looking Inside Cells
What does cell wall mean?
A rigid layer that surrounds the cells of plants and some other organisms.
What is the definition for DNA?
The genetic material that carries information about an organism and passes from parent to offspring.
What does diffusion mean?
The process by which molecules move from an area of higher concentration to an area of lower concentration.
What does Photosynthesis mean?
The process by which a Cell captures energy in sunlight and uses it to make food.
The process by which cells obtain energy from glucose.
How Do the Parts of a Cell Work?
Each kind of cell structure has a different function within a Cell.
What is compounds?
Compounds form when two or more elements combine chemically.
Which is it: Active transport depends on (sugars/proteins) to move molecules across the cell membrane.
Answer: proteins
What happens during Photosynthesis?
During photosynthesis, plants and some other organisms absorb energy from the sun and use the energy to convert carob dioxide and water into sugars and oxygen.
What happens during Cellular Respiration?
During cellular respiration, cells break down glucose and other molecules from food in the presence of oxygen, releasing energy.
What does mitochondria mean?
Rod-shaped organelles that convert energy in food molecules to energy the cell can use to carry out its function.
What compounds Do Cells Need?
Some important groups of organic compounds that living things need is carbohydrates, lipids, proteins, and nucleic acids. Water is a necessary inorganic compound.
What is the Importance of the Cell Membrane?
Substances that can move into and out of a Cell do so by means of one of two processes: passive transport or active transport.
What happens when the Sun as an Energy Source?
What is fermentation?
An energy-releasing process that does not require oxygen.
What is the difference between multicellular and unicellular?
Unicellular organisms consist of a single cell that performs all life functions, while multicellular organisms are composed of many specialized cells working together.
What is elements?
An element is any substance that cannot be broken down into simpler substances.
What is an Osmosis?
What is stage 1 on Photosynthesis?
Capturing the Sun's Energy?
What happens during fermentation?
What happens when cells work together?
In multicellular organisms, cells are organized into tissues, and organ systems.
Which groups of organic compounds found in living things are NOT energy rich?
proteins and nucleic acids.
What is stage 2 of photosynthesis?
Using energy to make food?
What is one stage of Cellular Respirtation?
1. Occurs in the cytoplasm of a cell
2. Takes place in the mitochondria.
