An organism is a living thing that is made up of cells, it can be multi-celluar which is an organism made up of many germs/cells or unicelluar that is only made up of one cell e.g. bacteria
Prokaryotic cells don't contain a true nucleas, membrane bound organelles or linear DNA
Eukaryotic cells contain a true nucleas, membrane bound organelles and linear DNA
Some organisms are only made up of one cell e.g. bacteria
Some organisms are composed of many cells
a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding
Stigma, style, Ovary
Stigma is sticky for pollen on insects to stick to flower to pollinate
The style has pollen tubes that sperm cells from the pollen to the egg
Ovary contains eggs that gets fertilized, and the eggs develop into seed and the ovary develops into a fruit
Anther is the part of the stamen that produces pollen
Filament is the thin stalk that supports the anther
Petal is the part that is bright that attracts pollinators
Ovule is the organ that forms seeds in flowering plants
Sepal is the part that protects the flower while it is still a bud
Receptacle is the part of the flower stalk where the parts of the flower are attached
Peduncle is the stalk that joins the base to the flowers and fruits
Plant cells have chloroplasts, cell walls and large vacuoles while animal cells have no cell wall or chloroplasts and small or non-existent vacuoles
Cell wall is a relatively rigid area that is present outside the cell membrane. It gives cells its shape and is made by the cytoplasm
Chloroplasts are in plants that use photosynthesis to gain energy
Nucleus contains DNA which are ‘instructions for living’ – it acts as a control centre
Ribosomes synthesise proteins from the instructions in genes
Cytoplasm is a jelly like material that keeps everything in place
Mitochondria is a double membrane that is responsible for cellular respiration
Vacuoles are storage for a cell, containing water, waste and other dissolved substances
Cell membrane is a thin boundary that acts as a permeable barrier that controls movement of substances in and out of the cell
At the top of the microscope there are two eyepieces, or ocular lenses, which the observer looks through to see the image in the microscope
The low power objective lens magnifies the image 10x, gives low magnification
The high-power objective lens magnifies the image 40x, gives high magnification.
The objective lenses and the magnification of the image can be changed by moving the revolving nosepiece.
The slide is held firmly in place by the stage clips. On some microscopes the slide can be moved around using the mechanical stage.
The large knob is the coarse focus knob and can be used to bring the specimen into focus. The smaller knob is the fine focus knob and can be used to make small focus adjustments.
The amount of light is controlled by the light adjustment dial. The light travels through the hole in the stage, which is the platform on which the slide of the specimen is placed.
A microscope magnifies, turns the specimen upside down and back to front
Multiply the objective lens power by the ocular lens power to calculate the total magnification
