MindMap Gallery Cell Mind Map
Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.
Edited at 2020-10-08 03:59:06Mind maps are a great resource to help you study. A mind map can take complex topics like plant kingdom and illustrate them into simple points, as shown above.
Mind maps are useful in constructing strategies. They provide the flexibility of being creative, along with the structure of a plan.
Vitamins and minerals are essential elements of a well-balanced meal plan. They help in ensuring that the body is properly nourished. A mind map can be used to map out the different vitamins a person requires.

Cell-Mind-Map
Animal cells
- do not have fixed shape
- do not have cell wall
- do not have vacuoles
- do not have chloroplast
- food storage at glycogen
- have centrioles
Epithelial tissues
- squomous epithelium
- cuboidal epithelium
- columnar epithelium
- sratified epithelium
- stratified squamous
- found in epidermis of skin and in the lining of the innermost layer of esophagus
- sratified cuboidal
- found in the excretory duct of sweat glands
- stratified columnar
- found in the secretory ducts of the mamary glands
- pseudostratified epithelium
- appear to be layer but layer do not exist
Cell wall
- tough, rigid, thick non-living structure
- give very difine shapes
- Function:
- maintaining the shape of the cells
- providing strength and give mechanical support
- maintains the turgidity of cells
- allow exchange substance during homeostasis
- an important reserve of carbohydrates
Plasma membrane
- encloses the cytoplasm/protoplasm of the cells
- provides shape and protection for cells
- semi-permeable or selective permeable
- protein are embedded in phospholipid bilayer
Cytoskeleton
- made of filamentous protein networks and skeleton of the cells
- microfilament
- microtubules
- intermediate filaments
Nucleus
- largest and most prominent organelle
- oval or sperical shape
- store genetic material in the form of DNA
- Nucleolus
- to synthesize ribosomal RNA subunits for the synthesis of protein
Endoplasmic Reticulum(ER)
- Rough endoplasmic reticulum(RER)
- next to nucleus
- synthesizing protein,modifying,packaging and transport of secretory proteins
- Smooth endoplasmic reticulum(SER)
- diverse metabolics activities
Ribosomes
- small,solid, spherical granules
- an assembly of two ribosomal RNA(rRNA) that are synthesizedd in nucleus
- synthesized protein molecules
Nerve tissues
- neurones
- a cell body
- dendrites
- the axon
- neuroglial cells
Mitocondria
- bounded by two layerof membrane
- the cristae partially divide by mitochondrial fluid called mitochondrial matrix
- mitochondrial matrix contains enzymes, DNA and ribosomes
- powerhouse of cell
- energy production for the cell
Chloroplast
- biconvex disc shape
- have their own DNA, RNA and ribosomes
- enclosed by two memmbranes separated by intermembrene space
Lysosomes
- dark spherical bodies, recyling center of the cell
- contains hydrolytic enzymes
- to digest macromolecules in the cells
- recycling centre
- also digest the remains of dead organelle(autolysis process)
Golgi body
- consist of a stack of flattened membranous sacs known as cisterinae
- receives,stores,concetrate,modifies,finishes and sorts proteins
Cartilage
- Hyaline cartilafge
- most common form
- Elastic cartilage
- contains many elastic fibers giving int a yellowish color
- Fibrous cartilage
- contains a dense network of collagenn fibers
Blood
- Red blood cells ( Erythrocytes)
- White blood cells ( Leukocytes )
- Granulocytes
- Neutrophils
- eosinophils
- Basophils
- Agranulocytes
- Lymphocytes
- Monocytes
- Platelets ( Trombocytes)
Bones
- act as lever
- converting muscle contraction into movement
- Spongy bones
- found in the center of flat bones and in the end of long bones
- Compact bones
- form by osteocytes located in the lacunae
Plant cells
- have fixed shape
- have cell wall
- have vacuoles
- maintaining turgidity of cells
- have chloroplast
- contain chloropyll for photosynthesis
- food storage at starch
- do not have centrioles
Eukaryotic cells
- Consist plants,animals,funfi,slieme moulds,protozoa and algae
- chromosome are present
- have distinct nucleus
- many membranous organelles
- cell wall was made by cellulose
- undergo mitosis and meiosis
Prokaryotic cells
- Consist of bacteria and archeabacteria
- no chromosom,only circular DNA stands
- no nucleus
- cell wall made by peptidoglycan
- undego binary fusion
