CELL STRUCTURE
What are the two main groups into which cells are classified?
Cells can be classified as eukaryotic or prokaryotic.
Prokaryotic cells are those that do not have an enclosed nucleus. Eukaryotic cells are those with a nucleus enclosed by a membrane.
What is cell secretion?
Cell secretion is the external elimination of substances produced by the cell
What is mitosis?
Mitosis is the process in which one eukaryotic cell divides into two cells identical to the parent cell
What is the primary energy source of living organisms on earth?
The sun
What is the highest-grossing film of all time?
Avengers: Endgame
Do the cells of bacteria have a nucleus?
In bacteria, genetic material is contained in the cytosol and there is NO internal membrane that encloses a nucleus.
How do cells obtain the energy they need to function?
Cells obtain energy for their metabolic reactions from breaking down organic molecules with a high energy content. This energy is mostly stored as ATP molecules.
The process of obtaining energy in order to produce ATP molecules is called cellular respiration.
What is the importance of mitosis in embryonic development?
Every embryo grows from a single cell that undergoes mitosis and generates other cells that also divide via mitosis, forming tissues and complete organs.
How is light from the sun transformed into the chemical energy used by living organisms on earth?
Photosynthesis
What year did Facebook launch?
2004
What is the main function of plasma membrane?
Since it is selectively permeable, the plasma membrane plays an important role in the entrance and exit of substances.
What is the difference between aerobic and anaerobic organisms?
Aerobic organisms are those whose cells do not survive without oxygen, since they depend on aerobic cell respiration to obtain energy for ATP production. Anaerobic organisms are those that live or can live in environments devoid of oxygen.
Some tissues are able to regenerate when injured.
What is cellular regeneration?
What is the chemical equation for photosynthesis?
6 CO₂ + 6 H₂O + light --> C₆H₁₂O₆ + 6 O₂
What year was the first iPhone released?
2007
What is the plasma membrane of the cell?
The plasma membrane is the outer membrane of a cell, it encloses the cell itself, maintaining specific conditions for cellular function within the cell.
What are the three phases of cell respiration?
glycolysis, the Krebs cycle and the respiratory chain (also known as the electron transport chain).
What is the cell cycle?
the time period that begins when the cell is created and ends when it is divided by mitosis, creating two daughter cells. The cell cycle is divided into interphase and the mitotic phase.
Which chemical element is at the center of the chlorophyll molecule?
magnesium
Who painted the Mona Lisa?
Leonardo da Vinci
What are the three main parts of a eukaryotic cell?
Eukaryotic cells can be divided into three main parts: the cell membrane that physically separates the intracellular space from the outer space by enclosing the cell; the cytoplasm, the interior portion filled with cytosol (the aqueous fluid inside the cell); and the nucleus, the membrane-enclosed internal region that contains genetic material.
What are the types of cell respiration?
aerobic cell respiration, a reaction with the participation of molecular oxygen (O₂)
anaerobic cell respiration, without the participation of molecular oxygen and which uses other inorganic molecules as an oxidant instead.
G1, S and G2 (the letter G comes from “gap”, meaning interval or breach, and the letter S comes from “synthesis”, indicating the stage in which DNA replicates).
What are the three stages of interphase
What do ATP and ADP mean?
ATP is the abbreviation of adenosine triphosphate, a molecule made of one adenosine molecule bound to three inorganic phosphate ions. ADP is an abbreviation of adenosine diphosphate, which is two molecules of phosphate bound to one molecule of adenosine.
What is the rarest M&M color?
Brown
