What are the four main types of cells ? Animal,plant,fungal,bacterial
What does an animal cell have? Cell membrane, cytoplasm, mitochondria, ribosome, nucleus
What does a plant cell have? Cell wall, cell membrane, mitochondria, cytoplasm, ribosomes, nucleus, vacuole, chloroplast
What does a fungal cell have (YEAST)? Cell wall, cell membrane, cytoplasm, mitochondria, ribosomes, nucleus
Plant cell wall is made up of ? Cellulose
What is a bacterial cell have? Cell wall, cell membrane, cytoplasm, ribosomes, plasmids, large circular chromosomes
Fungal and bacterial cells are not made up of ? Cellulose
Nucleus controls? Cellular activities and stores DNA
Cell membrane controls ? What material goes in and out of the cell
Cell wall provides? The cell with structural support
Cytoplasm is ? Where the chemical reactions take place
Ribosomes is? Where protein synthesis occurs
Mitochondria is ? Responsible for areobic respiration
Vacuole is where? Cell sap is stored and helps support the cell
Chloroplast contains? Chlorophyll to trap light energy for photosynthesis
Large circular chromosomes is? Where bacterial DNA is stored
Plasmids contain? Extra DNA to help survival
These structures are called ? Organelles
(Specialised cells to do specialised jobs) Sperm cell needs? A tail to swim, many mitochondria and 1/2 of the genetic information
Mitosis is the biological name for ? Cell division
Mitosis is important to multicellular organisms for? Growth, repair and replacement of lost and damaged cells
Mitosis is important to unicellular organisms for? Reproduction
Give an example of a multicellular organism ? Humans
Give an example of a unicellular organism ? Fungi and bacteria
Mitosis is controlled by ? The nucleus
DNA is found in the form of and where? Chromosomes in the nucleus (of most cells)
The genetic information in organisms is in the form of? DNA
Human have how many chromosome complements? 46
Female chromosome can be written as ? 44+xx
Male chromosomes can be written as ? 44+xy
Ordinary body cells (somatic) have ? 2 SETS of "23" chromosomes
2 SETS OF "23" chromosomes are described as ? Diploid
Sex cells (gametes) have only ? 1 SET of "23" chromosomes
1 SET of "23" chromosomes are described as ? Haploid
Red blood cells have NO? CHROMOSOMES
Haploid gametes fuse at fertilisation to form? Diploid 2YGOTE
A 2YGOTE IS A ? Single fertilised egg (diploid)
What is stage 1 of mitosis ? DNA in the nucleus replicates
What is stage 2 of mitosis? Chromosomes shorten and thicken and become visible
What is stage 3 of mitosis? Nuclear membrane breaks down and chromosomes line up on the cells equator
What is stage 4 of mitosis ? Spindle fibres pull chromatids to the opposite poles of the cell
What is stage 5 of mitosis ? New nuclear membrane form and cytoplasm starts to separate
What is stage 6 of mitosis ? Cytoplasm divides and 2 IDENTICAL daughter cells are formed
