Grade 10 Biology Mind map
Transcript of Grade 10 Biology Mind map
-The parts of a animal cell are rough endoplasmic reticulum, smooth endoplasmic reticulum, nucleolus, nucleus, chromatin, cell membrane, ribosomes, Golgi apparatus, cytoplasm, lysosome, mitochondrian, vacuole, cytoskeleton
-The parts of a plant cell are nucleolus, rough endoplasmic reticulum, smooth endoplasmic reticulum, ribosomes, central vacuole, cytoskeleten, cytoplasm, chloroplast, cell wall, cell membrane, mitochondrian, Golgi apparatus, nucleus
-The parts of a compound microscope is the eyepiece/ocular lens, tube, arm, stage clips, coarse adjustment knob, fine adjustment knob, lamp, base, revolving nose piece, lens, stage, diaphragm
-To properly carry a microscope you hold the arm and support the base
-Never use the coarse adjustment knob under power objective lens because it could damage the lens
-Two procedures that you should do to properly store a microscope is put the wrap the cord, was the slide and throw coverslips away
-When drawing a scientific diagram, state the title, the figure # and a descriptive statement. Use a pencil and label the parts of the diagram using a ruler to draw lines. Last of all, you have to record the magnification.
Cells - The Basic Unit of Life
The Cell Cycle: From Mitosis to Specialized Cells
Organs and Organ Systems in Animals and Plants
Advances in Biological Technologies
-the medical imaging technology used today are x-rays, x-ray fluoroscopy, x-ray radiotherapy, ultrasound, computed assisted tomography and magnetic resonance imaging or MRI
-Organ donation is 14 in every 1 million people
-most common organs that are donated by living donors are kidney, liver, lung, small bowel and the pancreas
-gene therapy involved replacing an absent or faulty gene with a normal gene
-a virus that has been modified to not cause disease, is used to carry a replacement gene into the cell to correct the defect
-currently gene therapy is an experimental procedure, but in the future gene therapy may be used to treat cancer, inherited disease and viral infections
-cloning creates a genetically identical organism that is an exact copy of a gene, cell, tissue, or organism
-The two most common methods used to clone plants is vegetative propagation and grafting
-The cloning of humans raises moral and ethical concerns
-Reproductive cloning involved the transfer of a nucleus from a donor body cell into an egg cell that has no nucleus.
The egg is then transferred to the womb of a mother and begins o grow. The embryo contains genetic info tha is identical to the original body cell. This type of cloning is useful for cloning endangered animals.
-Gene cloning involves the transfer of a gene into bacteria so that the gene can be reproduced multiple times
-The purpose of therapeutic cloning is to harvest embryonic stem cells and use it to regrow healthy tissue where there are damaged tissue.
-the concerns of reproductive technology is whether it is safe, who owns the technology, the standards and codes of practice that are in place and the definition of life
-The cell cycle consists of three phases. The G1 phase is where the cell grows, the S phase is where the DNA is replicated, the G2 phase is where the cell prepares for mitosis and the M phase is where cell division occurs.
-Cell division consists of mitosis which consists of prophase, metaphase, anaphase and telphase which finishes off with cytokenisis.
-The purpose of the cell cycle is to repreoduce cells and grows and repairs old cells to keep functions working.
-Mitosis is cell division and when the nucleus splits into two equal parts
-A chromosome is a long piece of coiled DNA and proteins
-Centromere is the middle of chromosomes
-Sister chromatids are two identical chromosomes.
-cytokenisis splits the cytoplasm and the nuclei in two which allows cell reproductions to occur
-The four main types of animal tissue are epithelial tissue, connective tissue, muscle tissue and nervous tissue
-The four main plan tissues are meristematic tissue, epidermal tissure, ground tissue, vascular tissue.
- A stemm cell is a unspecialized cell that can form into specialized cells when exposed to proper environmental conditions
-Embryonic stem cells are found in the embryos, embryonic stem cells are able to undergo differntiatio to other cell types
-one pracical use of stem cell research are finding treatments to illnesses
-Plant stem cells are called meristematic cells.
Groups of cells that function together to preform specialized tasks are called tissues
-specialized cells and tissues are the same thing, tissues are just many cells that work together to complete a job
-The epithelial tissues and epidermal tissues are quite similar they both protect the inner structures and allow materials to come in and out
-The functions of the roots of the plant is the anchor the plant and also collects water as well as stores food that is made in other parts of the body
-The job of the leaf is to use the tissues of the leaf to accomplish photosynthesis.
-The function of the stem is to transport water and nutrients throughout the parts support the leaves and flowers.
-The major function of the flower is to reproduce
-The digestive organs are the mouth, esophagus, stomach, liver, pancreas, intestines, rectum and anus
-All the organ systems are the integumatory system, skeletal system, muscular system, digestive system, respiratory system, circulatory system, nervous system, endocrine system, excretory system, reproductive system, and lymphatic system
-Diffusion is when the gases are exchanged in cells so CO2 and oxygen levels will be equal
-Nephrons help filter the waste in your kidneys
-Homeostasis means a steady state, htis is the acceptable range of physical and chemical conditions in which your body can operate efficiently
