Flashcards in Chapter 1 7N1 Deck (25):
A multicellular organism with a nucleus (excluding a blood cell) and a cytoplasm wrapped around a cell membrane.
This consists of one cell (unlike a multicellular organism) that has all life needs to survive.
A rectangular, fragile piece of glass which specimens goes on to be studied on using a microscope.
An object with cells of any kind (like an onion) which is used to be seen on through a microscope.
A scientific tool used to observe cells of an object using an objective lens (to magnify the object.
This is the part of an animal cell which processes photosynthesis (the process in which plants use the sunlight to photosynthesis it into nutrients).
The vacuole is the space of any living cell where air or liquid is stored.
This is the part of the animal cell that protects it. It uses a fibre called cellulose so it can no longer be flexible.
It is an acronym that stands for the following:
Movement, respiration, sensitivity, growth, reproduction, excretion and nutrition.
This is the part of the cell that does respiration (the process for converting nutrients into energy for the cell.
This controls what comes in and out of the cell.
The part of the cell where chemical reactions occur.
This contains the genetic information (the way to make new cells) of the cell.
A single cell which is either unicellular or multicellular.
The process of viewing someone in a closer distance.
Cells (in multicellular organisms) that need to perform specific tasks in the body.
Nerve cell adaptations
The sheath (tail) is used as an insulator to communicate with other parts of the body to activate the nervous system (when needed) and is one of the largest cells in the human body.
Egg cell adaptations
The egg is half of two parts of reproduction (the other half is the sperm cell).
Sperm cell adaptations
The sperm has a tail to move and find the egg (for reproduction) and a decent amount of mitochondria for energising.
(Of an organism) depending on many other kinds of cells to survive.
Red blood cell adaptations
They are flexible to fit though narrow blood vessels and are in a small disc shape to absorb oxygen (mostly from the lungs).
The spreading of gas particles from an area of high concentration to an area of low concentration.
Rate of diffusion
The rate of diffusion is the speed of gas particles (or the amount of kinetic energy). The high the temperature, the more kinetic energy the gas particles have.
This is the process of a fully grown baby cell (after reproduction is complete) splitting into two equal cells.
