Tissues

• what are tissues?

  tissues are similar cell lying side by side that work together to perform the same function
• what are the two types of plant tissues?

  Meristematic tissue and Permanent tissue
• meristematic tissue is also known as Meristem
• what is the location of the meristematic tissue?

  growing points of parts such as tips of roots stem branches bark and wood of trees
• what are the two types of meristematic tissues?

  apical Meristem and Lateral Meristem
• apical Meristem are also known as terminal Meristem
• Lateral Meristem also known as cambium Meristem
• where are the apical Meristem present?

  tips of roots, stem and also in growing young leaves
• location of Lateral Meristem?

  below the bark increases the girth of the stem
• what are permanent tissues?

  cells which have lost their ability to divide
• what are the types of permanent tissue?

  protective

  supporting

  conducting
• protective tissues are found on the surface of root, stem and leaves
• types of supporting tissue in plant?

  Parenchyma, collenchyma, sclerenchyma
• the cell wall of parenchyma is thin
• the cell wall of sclerenchyma is thick
• what is the function of parenchyma?

  store food in potatoes and give temporary support
• what is the function of chlorenchyma?

  help in the production of food by photosynthesis
• where is parenchyma found?

  soft parts of plants such as cortex and pith
• where is collenchyma found?

  in the leaf stalks
• what is the function of collenchyma?

  to provide support to the parts of the plant
• the cell wall of sclerenchyma is?

  thick wall due to the deposition of Lignin
• where is sclerenchyma found?

  in the stems and veins of leaves
• what is the function of sclerenchyma?

  provides strength to the parts of plant
• conducting tissues also known as vascular tissues
• xylem and phloem are the two types of conducting tissues
• what are the main kinds of animal tissues?

  Epithelial, connective, muscular, and nervous tissues.
• where is the squamous epithelium found?

  lining of mouth nasal cavity blood vessels and lymph vessels
• squamous epithelium cells are thin flat with prominent nuclei closely packed
• location of cuboidal epithelium?

  parts of kidney tubules and glandular ducts like salivary gland and pancreatic
• location of columnar epithelium?

  lining of the intestine, stomach
• location of ciliated columnar epithelium?

  windpipe
• ciliated epithelium have thread like projections called cilia
• location of glandular epithelium?


  tear gland, sweat gland and liver

  inner lining of intestine and stomach
• location of stratified epithelium


  skin and cornea
• types of connective tissue

  connective tissue proper

  supportive connective tissue

  fluid connective tissue
• connective tissue proper serves for packing and binding the organs
• types of connective tissue proper

  areolar tissue

  adipose tissue

  fibrous connective tissue
• location of the areolar tissue

  beneath the epidermis of the skin
• beneath the epidermis of the skin

  padding under the eyes

  around the Kidneys

  eyeball
• tendons connect muscle to bones
