hey mate there's your answer
chapter=6 tissue
first of all in this chapter don't learn the question answers of this chapter because all the question were comes on chapter based. only read the chapter yourmind gaves you the answer automatically
first of all you have plant tissue in this chapter it plant tissue there are meristmatic tissue and permanent tissues.
meristmatic tissues contains apical meristems, lateral meristems and intercalary meristems.
apical meristems are present at the growing tips of stem and roots and increases the length of the stem and roots. the girth of the stem or root increases due to lateral meristems. intercalary meristems is the meristems which are present at the base of the leaves. permanent tissues contains two types of tissue first is simple permanent tissues and second is complex permanent tissues. simple permanent tissues contains paranchyma, chollenchyma and sclerenchyma another type of paranchyma is aeranchyma. the few layers of the cell form the basic tissue is called paranchyma. they are also loosely packed. the chlorenchyma contains chlorophyll and performs photosynthesis it also gaves mechanical support to the plants we can find this tissue in plants below the epidermis. let's talk about sclerenchyma tissues it is the tissue which makes plant hard and stiff you can see it in the husk of a coconut. this tissues have dead cells they are long and narrow they have no intercellular space this tissues present in the stems around the vascular bundle it provides strength to plants parts. now it is epidermis the outermost layer of the plants are called epidermis. it is made of single layer of cells it is also included in protective cells the surface of a plant have outer covering of epidermis. there are small pores in the epidermis which we called as stomata. transpiration also takes place with the help of stomata. cells of corks are dead and also have a chemical called suberin in their walls. complex permanent tissues....
they contains xylem and phloem
xylem consists trachieds,vessels,xylem paranchyma and xylem fibres.they have thick walls. they have thick walls and many of them are dead cells tracheids and vessels are tubular structures.
phloem consists seive tubes, companion cells,
phloem paranchyma and phloem fibres...
animal tissues .
first is epithelial tissue
there are four types of epithelial tissue
1. squamous epithelial tissues
2. cuboidal epithelial tissues
3. columnar epithelial tissues
4. stratified squamous epithelial tissues
connective tissues....
they are loosely packed and have intercellular matrix may be jelly like, fluid etc.
blood has two cells red blood cells and white blood cells. two bone connected to each other by another type of connective tissue is called ligaments. tendons connect muscle to bones and are another type of connective tissue. another type of connective tissue is cartilage.
hope it helps you
