Question

What are the types of cell and tissues?

Answer 1

it might be placed into one of two groups: the prokaryotes and the eukaryotes. A prokaryote is an organism that is almost always single-celled (except for prokaryote colonies), always reproduces by means of binary fission and does not have a cell nucleus or any other organelles contained within a membrane. The prokaryote’s DNA travels openly around the cell

Epithelial tissue covers the body surface and forms the lining for most internal cavities.  The major function of epithelial tissue includes protection, secretion, absorption, and filtration.  The skin is an organ made up of epithelial tissue which protects the body from dirt, dust, bacteria and other microbes that may be harmful.   Cells of the epithelial tissue have different shapes as shown on the student's worksheet.  Cells can be thin, flat to cubic to elongated.  

Connective tissue is the most abundant and the most widely distributed of the tissues.  Connective tissues perform a variety of functions including support and protection.  The following tissues are found in the human body, ordinary loose connective tissue, fat tissue, dense fibrous tissue, cartilage, bone, blood, and lymph, which are all considered connective tissue.  

There are three types of muscle tissue: skeletal, smooth, and cardiac.  Skeletal muscle is a voluntary type of muscle tissue that is used in the contraction of skeletal parts.  Smooth muscle is found in the walls of internal organs and blood vessels.  It is an involuntary type.  The cardiac muscle is found only in the walls of the heart and is involuntary in nature.

Nerve tissue is composed of specialized cells which not only receive stimuli but also conduct impulses to and from all parts of the body.  Nerve cells or neurons are long and string-like.

In tissues the simplest combination is called a membrane, or a sheet of tissues which cover or line the body surface or divide organs into parts.  Examples include the mucous membrane which lines body cavities.  Tissues combine to form organs.  An organ is a part of the body which performs a definite function.  The final units of organization in the body are called systems.  A system is a group of organs each of which contributes its share to the function of the body as a whole.

Answer 2

there are many types of cells and tissues and actually i dunno how many type but.........

for e.g:- muscle cell

              liver cell

etc......

Answer 3

cells are mainly of two types

1.prokaryotic cell(have membrane bounded nucleus)

2. eukeryotic cells(lack membrane bounded nucleus)

tissues may b plant tissues or animal tissue

PLANT TISSUE:

1.merismetic tissue(capacity to divide)

2.permanent tissue(dont divide)

3.epidermal tissues

4. ground tissues

5.mechanical tissues

6. collenchyma  tissues

7. scleranchyma tissues

8.xylem tissues

9.phloem tissues



ANIMAL TISSUES:

1.epithilial tissues

2.soft connective tissues

3.hard connective tissues

4.mascular tissues

5.skeletal tissues

6.smooth tissues

7. cardiac tissues

8.nervous tissues
