Flashcards in Biology-Chapter 1 Deck (26):
The amount that an image of something is scaled up when viewed through a microscope
It is the shortest distance between two points of a specimen that can still be distinguished by the observer or camera system as separate entities.
An organism refers to any individual living things that can react to stimuli, reproduce, grow, and homeostasis
the part of the animal cell that controls the cell.
A 'jelly like' substance where the chemical reactions take place
It is a wall around the cell that controls what goes in and what goes out
This is where respiration happens
It stands for Movement, Respiration, Sensitivity, Growth, Respiration, Excretion and Nutrition
This strengthens and provides support for the Plant Cell
This contains a water liquid called sap
This is where photosynthesis happens
An instrument used for viewing very small objects such as cells, samples etc.
An individual animal,plant etc. used as an example of its species
It is a thin flat piece of glass, used to hold objects for examination under a microscope
A microscopic structure containing material enclosed by the basic structural unit of organisms
An unicellular organisms only have one cell
A cell that has a specialised job to do something
Nerve Cell Adaptations
The nerve cell has several adaptations which allows it to carry out its necessary functions.
Sperm Cell adaptations
One example: The head contains genetic information and an enzyme to help penetrate the egg cell membrane
Egg cell adaptation
A single egg cell is called an ovum. Collectively, eggs and sperm are called gametes or sex cells. When fertilisation occurs, an egg (ovum) and a sperm cell fuse to form a zygote. Eggs and sperm have several important adaptations linked to their structure.
Root hair adaptation
Plants absorb water from the soil by osmosis. Root hair cells are updated for this by having a large surface area to speed up osmois
Something which has more than one cell
Red blood cell adaptation
They have adaptations that make them suitable for this: they contain haemoglobin - a red protein that combines with oxygen.
The spreading of something more widely and quickly
The rate of diffusion
How quickly something spreads widely and quickly
